Sanctions can provide assurance for cooperative agents, not just deter egoists [causal]

It is true that in AG the players share a first preference for a)bp. But, as indeed Sen says, they do both need assurance, and the prospect of the enforcement of a contract might be how the assurance was secured. This points up an important difference in the possible role of sanctions, a difference relevant to political theory. The addition of sanctions may change the utilities for a basically egoistic agent, or they may provide assurance for an agent who is basically cooperative. The latter, a very important possibility, is connected to a point I shall consider later: that the disposition to cooperation is typically cost sensitive.

XREF: This contrasts two distinct roles of sanctions in game theory and political theory — deterrence for egoists versus assurance for cooperators — which connects to Hobbesian vs. Rousseauian accounts of the social contract. DEFINE: Distinguishes between the utility-changing role of sanctions for egoistic agents and the assurance-providing role for cooperative agents, a key conceptual distinction in the author's framework.

Successful cooperation requires mutual knowledge of preferences, not just shared ones. [causal]

Each needs to know that the other has the AG preference schedule. Moreover, each needs to know that the other knows that he (the first) has that preference schedule. If that is not so, each can conduct, and can replicate, reasoning that will lead him to believe that there is a risk that the other will defect, and hence he will defect himself, … Without this knowledge, or something that will stand in for it, the cooperation will unravel.

XREF: This is the classic game theory concept of common knowledge (Lewis/Schelling), closely tied to the iterated prisoner's dilemma and coordination games.

Confused intentions can erase the truth of human action. [causal]

The baroque structure of these intrigues, in which an agent might act to create the impression that a second agent was acting so as to create the impression that the first agent was engaged in a conspiracy (for instance, that one), must surely have resulted in a situation in which no one really understood what anyone was doing; and this lack of understanding will also have affected the situation to be understood. Since such a situation is structured by the agents' intentions, and their intentions are conditioned by their increasingly confused grasp of others' intentions, there comes a point at which there is no truth of the matter about what they are doing.

DEFINE: Introduces the idea that action-truth depends on the coherence of agents' mutual intentions, so recursive confusion dissolves objective answers.

Diego Gambetta, Trust - Making and Breaking…, loc. 115

Cooperation dispositions vary with the cost involved. [causal]

Besides that possibility, however, there are motives to cooperation that are not egoistic, but are more restricted than the kind of thing represented by the simplest psychological generalization of the preference schedule OR. There are general dispositions to cooperate which are conditional, and in particular are sensitive to costs: an agent will cooperate if it does not cost too much, but beyond this threshold he will not. The threshold may itself change over time. Moreover, failing perfect knowledge of the other agents' dispositions, he may take a risk on a cooperative initiative if the cost of being deceived falls below a certain threshold. In these various … (R3) A disposition to cooperate is cost sensitive.

DEFINE: Introduces the R3 disposition: cooperation is conditional and cost-sensitive, falling off beyond a threshold.

Cooperation requires mutually necessary actions beyond any agent's control. [definitional]

Two agents cooperate when they engage in a joint venture for the outcome of which the actions of each are necessary, and where a necessary action by at least one of them is not under the immediate control of the other.

DEFINE: Provides a precise, testable definition of cooperation rather than a vague colloquial sense.

Diego Gambetta, Trust - Making and Breaking…, loc. 147

Cooperation is symmetric but dependence is not. [definitional]

Cooperation is a symmetrical relation: if X cooperates with Y, Y cooperates with X (if that seems unnatural, read 'cooperates' as 'engages in a cooperative venture with'). Depends on, however, is a nonsymmetrical relation: if X depends on Y — in the sense that his getting what he wants out of the venture? depends on Y doing his part — it may or may not be the case that Y depends on X.

DEFINE: Distinguishes the logical symmetry of cooperation from the nonsymmetrical nature of dependence, a key disambiguation for the author's argument.

Diego Gambetta, Trust - Making and Breaking…, loc. 157

Cooperation requires rational assurance that partners won't defect. [causal]

Cooperation requires trust in the sense that dependent parties need some degree of assurance that non-dependent parties will not defect: as I have already said, this need not take the form of 'thick' trust, individually based belief, but it must take some form or other. The next step after this is to claim that, in general, people will not trust others enough to bring about cooperation unless their assurance is to some extent well based: that is to say, unless people are also in general motivated, one way or another, not to defect if they are in a nondependent position.

Diego Gambetta, Trust - Making and Breaking…, loc. 178

Cooperation arises from egoistic fear of sovereign sanctions [causal]

The motivation to cooperation is egoistic, since it lies essentially in the fear of the sanctions of the sovereign. However, the motivation to cooperation is also a macromotivation, because what the sovereign's sanctions are designed to bring about (among other things) is a motivation, in general, to cooperate. It is not an accident that, from egoistic considerations, the agent on these various occasions cooperated: he knew that what he had egoistic reason to do was, precisely, to cooperate.

DEFINE: Clarifies the distinction between egoistic (sanction-fearing) and macromotivation (system-designed) cooperation motives.

Diego Gambetta, Trust - Making and Breaking…, loc. 195

Egoistic cooperation springs from circumstance, not generalized cooperative commitment. [definitional]

An egoistic micro-motivation, lastly, is fairly self-explanatory: I have such a motivation to cooperate when, in those circumstances, I see it as in my egoistic interest to do so, but this is not because I am generally motivated, as in the Hobbesian system, to cooperate as such. This does not rule out the possibility that I may regularly find myself in such situations, or even that there may be some structure as a result of which I regularly find myself in such situations: to produce such a structure might be a triumph of the Invisible Hand. It will be a mark of this kind of motivation, however, in a pure form, that there will be no motivational momentum from one case of cooperation to the next.

DEFINE: Distinguishes egoistic micro-motivation from Hobbesian generalized cooperation as a technical concept.

Diego Gambetta, Trust - Making and Breaking…, loc. 199

Invisible Hand structures cannot self-regulate without implausible functionalist assumptions. [contrarian]

Without some general structure, egoistic micro-motivation merely returns us to the Prisoner's Dilemma. So if this kind of motivation is to do all the work, we need an Invisible Hand structure that will bring it about that a tendency to defect is offset by some other egoistic micromotivation (and will also allow this to be adequately known, etc.) But one needs extraordinarily strong and implausible functionalist assumptions to believe that such structures could be self-regulating and selfpreserving, and there is abundant evidence to hand, generated by a body of relentless social experiment, to show that they are not.

XREF: Ties to Prisoner's Dilemma theory and critiques of free-market self-regulation that assume rational self-interest produces collective good.

But if this is conceivable at all. [fact]

This will presumably have to be something like 'thick trust' - reliance on and between a group of persons in terms of their known dispositions, personal relations, and so on. It is not easy to see how this could be extended beyond a very small society. The only apparent way of taking it beyond that is to identify a particular set of people, a government or elite group, in whom thick trust is invested, and whose activities, example, or regulation serve to sustain cooperative activities throughout the society; but if this is conceivable at all, I find it impossible to see how such a structure could be the basis of our arrangements without an arrant degree of traditionalist or charismatic mystification.

Diego Gambetta, Trust - Making and Breaking…, loc. 219

In fact, that there is no one problem of cooperation: the problem is always. [fact]

In fact, that there is no one problem of cooperation: the problem is always how a given set of people are to cooperate. In a modern state, people are motivated by some version or degree of each of the sorts of motivations that have been distinguished, and their actions are often overdetermined, quite often by all four. The right question to ask, at this level of generality, is not which of these simple models could be made to do all the work, but rather what combinations of such motivations make sense.

Diego Gambetta, Trust - Making and Breaking…, loc. 228

Animal cooperation contradicts the competitive-Darwinism stereotype [contrarian]

The answers to such questions are important because so many non-biologists believe that the social behaviour of animals consists of nothing but strife and manipulation. If animal nature is the result of the competitive process of Darwinian evolution, then surely it must also be ruthlessly competitive. Such a conclusion does not follow from an acceptance of Darwinism. It is also a travesty of what biologists have observed and what most now believe.

Competing primates evolved larger canines to win mates. [causal]

Male polygynous primates that fight with other males for females have much larger canines than male primates that are characteristically monogamous (Harvey, Kavanagh, and Clutton-Brock 1978). Character-environment correlations of this type are known as adaptations. They catch our attention because they seem so well designed for the job they perform.

DEFINE: This highlight introduces the concept of 'adaptations' — correlations between an organism's traits and its environment that appear designed for a function.

Diego Gambetta, Trust - Making and Breaking…, loc. 260

Darwin's theory explains adaptation origins more than speciation [contrarian]

Much the most coherent explanation for the evolution of such phenomena is still Darwin's. Indeed, Darwin's proposal is much better seen as a theory about the origin of adaptations than as a theory about the origin of species.

DEFINE: Recasts the standard understanding of Darwinian theory, distinguishing the origin of adaptations from the origin of species as the theory's primary explanatory target.

Diego Gambetta, Trust - Making and Breaking…, loc. 262

Adaptive mechanisms differ from long-term gene frequency shifts. [definitional]

By analogy, Darwin referred to the differential survival of the characters that adapt an organism to its environment as natural selection. The Darwinian formulation emphasizes that the precise way in which a character enables an individual to survive or breed better is part of the process. The way in which the character works is not the same as the long-term changes in the frequencies of genes that are required for the expression of the character.

DEFINE: Distinguishes Darwin's functional conception of natural selection from the population-genetic view of evolutionary change.

Diego Gambetta, Trust - Making and Breaking…, loc. 273

Kin selection extends the obvious logic of parental sacrifice to relatives. [definitional]

The idea of 'kin selection' is an extension of the intuitively obvious point that animals will often put themselves at risk and do things that are bad for their health in the production and care of offspring.

DEFINE: Clarifies the concept of kin selection by grounding it in the intuitive behavior of parental care.

Diego Gambetta, Trust - Making and Breaking…, loc. 311

Even when both parents care for young, their interests do not coincide. [contrarian]

Even when both parents care for young, their interests do not coincide. They certainly have a common interest in their offspring’s survival, but they have diverging interests in as much as each one might be able to increase its reproductive success by spending time seeking extra mates elsewhere.

Diego Gambetta, Trust - Making and Breaking…, loc. 373

Withdrawing care of offspring must be matched by stepping up the search. [fact]

Given that each individual can affect its reproductive success in more than one way, if it reduces the effort devoted to one form of reproduction it must increase the effort devoted to the other by a specified amount in order not to reduce its overall reproductive success. Withdrawing care of offspring must be matched by stepping up the search for an additional mate.

Diego Gambetta, Trust - Making and Breaking…, loc. 383

Birds increase parental care when their mate disappears. [causal]

Therefore, animals capable of taking note of conditions should evolve so that they change the amount of time they allocate to care of the young in response to changes in those conditions. The model is simple, but the expectation is matched by many observations of birds increasing the parental care devoted to their offspring when their mate deserts or disappears.

XREF: This is classic parental investment theory, connected to Trivers and Clutton-Brock. The observation about mate desertion inducing increased care is a textbook finding in behavioral ecology.

Diego Gambetta, Trust - Making and Breaking…, loc. 405

Grasshoppers reared on black backgrounds survive by matching their environment. [causal]

Not only do such grasshoppers match their black environment, they prefer to settle on such backgrounds. It is obvious that grasshoppers with a conditional response to the environment in which they are reared are more likely to survive than those that are inflexible. They would also do better than those that go black on a probabilistic basis, matching the likelihood of becoming black to the probability of savannah fires. Clearly, many grasshoppers that go black probabilistically would do so at the wrong time and be highly conspicuous to predators as a result.

Diego Gambetta, Trust - Making and Breaking…, loc. 429

Animal behavior departures are often adaptive responses to ecology. [causal]

No animal behaves in the same way irrespective of conditions. Nor, of course, do humans. Departures from the norm are not necessarily pathologies generated by abnormal conditions. They may well be highly adaptive responses to particular ecological conditions.

Diego Gambetta, Trust - Making and Breaking…, loc. 442

Cooperation among strangers requires time and repeated future interaction. [causal]

Or if members of a group are not familiar with each other, no mutual aid occurs until they have been together for some time. As familiarity grows, individuals come to sense the reliability of each other. Furthermore, the expectation of an indefinite number of future meetings means that deception is a much less attractive option. The major message is this: in cooperative behaviour, conditions matter a lot.

XREF: Connects to game theory and the iterated prisoner's dilemma, where repeated play makes defection less attractive.

Diego Gambetta, Trust - Making and Breaking…, loc. 460

Biological interests need no motive to be maximized. [definitional]

Firstly, evolutionary process must be distinguished from its consequences; differential survival in the past does not necessarily mean social competition now. Secondly, in biology the outcome of differential survival is the ‘interest’, and no motive is required for that interest to be maximized by a given course of action.

DEFINE: Clarifies the technical distinction between evolutionary process and its current consequences, and between biological 'interest' and conscious motive.

Another's reaction validates one's prior experiential basis for action. [causal]

Central to these subjects' experience of rule breaching" is the role played by another's reaction to one's own action, in confirming the validity of the prior experience on which that action was based. As many authors have observed, without such confirmation the social world

DEFINE: Clarifies a mechanism in social rule-breaching: external reactions confirm the foundational experience that motivated the action.

Unpredictable low-intensity shocks harm animals more than predictable higher ones. [fact]

To take an extreme example, Seligman, Maier, and Solomon (1971) report that dogs subjected to random and unpredictable shocks of a relatively low intensity suffer much more than those who are receiving higher but predictable charges. Typically, the first group of dogs becomes listless, their physical condition worsens, and their normal interests diminish when compared with the group receiving the greater but predictable punishment.

XREF: Relates to learned helplessness research and the broader psychology of perceived control. Also connects to why predictable pain is psychologically preferable to unpredictable mild stress.

Trusting people tend to be more trustworthy and psychologically well-adjusted. [fact]

In general, they have found that those who are more willing to trust other people are likely to be equally trustworthy in that they are less likely to lie, cheat, or steal. They are also less likely to be unhappy or maladjusted, and are typically more liked by their friends and colleagues.

QUESTION: Does this correlation hold across cultures, or is trust willingness culturally conditioned?

Diego Gambetta, Trust - Making and Breaking…, loc. 525

Trust means confidence in another's future performance based on past claims [definitional]

The first substantive definition of 'trust' in the Oxford English Dictionary is 'confidence in or reliance on some quality or attribute of a person or thing, or the truth of a statement'. A later variant stresses the economic usage, defining it as 'confidence in the ability and intention of a buyer to pay at a future time for goods supplied without present payment'. Under either of these definitions, or the others offered in this volume, trust is based on an individual's theory? as to how another person will perform on some future occasion, as a function of that target person's current and previous claims, either implicit or explicit, as to how they will behave.

DEFINE: Provides the Oxford English Dictionary definitions of trust alongside a synthetic definition involving prediction of future behavior from prior claims.

Diego Gambetta, Trust - Making and Breaking…, loc. 529

Future interaction dramatically increases cooperation in Prisoner's Dilemma games. [causal]

Pruitt and Kimmel (1976) examined the extensive literature on the Prisoner's Dilemma game, and concluded that one important consideration for subjects is whether or not they view the interchange from a short-term or long-term perspective. In particular, if subjects believed that they would need to interact with each other after the study was concluded, and therefore the usual social and temporal isolation of such interactions was removed, their behaviour became considerably more cooperative.

XREF: Connects to Axelrod's work on the iterated Prisoner's Dilemma and the shadow of the future — repeated interactions sustain cooperation even among rational actors. Builds on: "Cooperation among strangers requires time and repeated future interaction."

Machiavellian players outperform chance in exploitative social situations [causal]

The finding of interest from this work for the argument here is that the most machiavellian of the players were most able to exploit the situation to their greatest advantage, and do much better than chance would

Confirmation-seeking bias appears across many real-world domains [fact]

By itself, a study such as Wason's might be dismissed on the grounds that it represents a fairly artificial laboratory task in which the subjects have little interest, but similar failures to seek disconfirmation have been observed in a number of different spheres. For example, Mitroff (1974) indicates that NASA scientists have a strong confirmation-seeking bias in their work, and Mynatt, Doherty and Tweeney (1977) report a similar bias amongst subjects attempting to discover the laws of an artificial universe simulated on a computer. Snyder and Swann (1978) conclude that subjects seek evidence of extroverted behaviour rather than its opposite when trying to evaluate a description of someone who has been described as extroverted. Tajfel (1969) makes the case that such a failure to seek disconfirmation, and an inability to recognize disconfirmation for what it is when it is presented to the individual by chance, are important factors in the maintenance of racial prejudice.

Anonymity increases willingness to inflict harm on others [causal]

Generally, it might be thought that there are two factors at work. The first is the impact of depersonification. In a number of experiments, it has been noted that subjects who cannot see or hear the person to whom they are reacting tend to inflict far more extreme punishments upon one another. The most famous study demonstrating this is Milgram (1963). In this, most subjects were willing to give electric shocks, which they had some grounds for believing could be dangerous and possibly lethal, to another person when that person was unseen and in another room. Most were not willing to do so when seated right next to the recipient of the shocks. Clearly, anything which increases contact between parties will reduce this tendency.

XREF: Connects to Milgram's obedience experiments and broader psychology of deindividuation, also relevant to online harassment/anonymity research. QUESTION: How does depersonification's effect interact with accountability structures, social norms, and digital interfaces today?

Knowing another person enables mutual understanding in communication. [causal]

Within any human society, the context in which a communicative act is offered is critical to its interpretation. This is true for the full range of such acts, from simple conversations to informal and formal contracts: even the most detailed of contracts cannot make explicit everything which must be understood for its interpretation. The beliefs which are held about another person at the time of communication are a significant part of what that context amounts to. Therefore, anything which contributes to a greater sense of knowing the other can contribute to the participants' belief in the possibility of mutual understanding.

Diego Gambetta, Trust - Making and Breaking…, loc. 705

Expressed attitudes only make sense within their communicative context. [causal]

However, the fundamental flaw in this work might be described as a failure to realize that expressed attitudes are communicative acts, and that they can only be satisfactorily understood in the appropriate context. This point is reflected in the fact that the most successful contemporary models of the attitudebehaviour relationship (e.g. Fishbein's) are those which try to build the context into the equation which relates one to the other (see Schuman and Johnson 1977).

XREF: Connects to attitude-behavior research and the context-dependent nature of survey/measurement responses.

Established trust systems withstand widespread fraud surprisingly well. [contrarian]

Despite its apparent fragility and our many attempts to do without it, it is clear that, in many societies where it is well established, trust is remarkably robust. Fraud is widespread in all the advanced economies, and is extremely costly to companies and individuals alike, but rarely

QUESTION: What mechanisms allow trust to remain robust despite pervasive fraud? Worth investigating the resilience factors.

Brute-force decision search fails under combinatorial explosion. [causal]

As was quickly discovered, the ‘brute force computing’ tactic, as the unbounded rationality assumption was known, was a failure because the decision space to be searched for any moderately realistic problem was of unmanageable proportions. For example, even contemporary machines take an inordinate amount of time to examine all possible two-move sequences in the opening stages of a chess game, because the number of branches in the relevant decision tree undergoes a combinatorial explosion. Not surprisingly, this tactic was quickly dropped, and much effort has subsequently been devoted to the development of more sophisticated and realistic alternatives. If we are to understood the development and maintenance of cooperative and trusting relations, similar unrealistic assumptions will have to be abandoned too.

XREF: Connects to the broader argument that rational-choice/unbounded rationality assumptions about cooperation must be abandoned, mirroring the chess example.

Diego Gambetta, Trust - Making and Breaking…, loc. 738

Economists treat trust as unexamined background to transactions. [contrarian]

Trust is central to all transactions and yet economists rarely discuss the notion.! It is treated rather as background environment, present whenever called upon, a sort of ever-ready lubricant that permits voluntary participation in production and exchange.

Diego Gambetta, Trust - Making and Breaking…, loc. 772

Trust is pre-monitoring expectations about others' future actions. [definitional]

I am using the word 'trust' in the sense of correct expectations about the actions of other people that have a bearing on one's own choice of action when that action must, be chosen before one can monitor the actions of those others.

DEFINE: Provides a precise operational definition of trust as expectations formed before verification is possible.

A reputation for unwavering truth makes lies more persuasive. [contrarian]

But the point is that his enemies did not know this. They thought that Yudhishthira could never be motivated to deviate from the path of truth. This is why the lie worked.

QUESTION: What does this suggest about strategic deception elsewhere—does credibility amplify the impact of rare deviations?

Sufficient incentives can corrupt even trustworthy individuals. [contrarian]

If the incentives are ‘right’, even a trustworthy person can be relied upon to be untrustworthy. ‘Every man has his price’: repugnant though it is to our sensibilities, the cliché captures the view that no one awards an infinite weight to his own honesty.

Diego Gambetta, Trust - Making and Breaking…, loc. 821

Reputation is a public inference from observed conduct to character. [definitional]

Our opinion is thus based partly on the theory we hold of the effect of culture, class membership, family line, and the like on a person’s motivation (his disposition) and hence his behaviour. The opinion which is publicly formed and held is this person’s reputation. Our problem in essence is to infer the person’s qualities from such data.

DEFINE: Reputation defined as publicly formed opinion inferred from qualities evidenced in behavior, filtering through theories of culture, class, and family.

Binding future choices can grant a first-mover advantage [causal]

From our point of view the interesting feature of the story is that Odysseus had the option of (quite literally) binding himself now to a future course of action (by excluding the option of trying to get to the Sirens). He exercised that option, and this enabled him to choose a further option (that of listening to the Sirens) which he would not have chosen had he not been able to so bind himself. … Odysseus’s customary self had, as game theorists would call it, a first-mover advantage over his bewitched self.

XREF: This is the classic Ulysses contract concept from game theory and precommitment strategies, with parallels in behavioral economics and rational choice theory.

Reputation-based equilibria label types without requiring face-to-face knowledge. [definitional]

At this equilibrium it is common knowledge that type 1 people are always honest and that type 2 people always cheat a little. But at no encounter does either party know who he is dealing with. Behaviour according to type is therefore what emerges at this equilibrium.

DEFINE: Explains how a pooling equilibrium works: type labels are common knowledge even though individuals never know who they're dealing with. Builds on: "Reputation is a public inference from observed conduct to character."

Diego Gambetta, Trust - Making and Breaking…, loc. 873

Rational suspicion can prevent mutually beneficial transactions entirely. [causal]

I begin by considering a 'dishonest' salesman, I formalize his disposition by the hypothesis that y exceeds a. To have an interesting problem I assume further that a is positive, that is y > a > 0. … The potential customer reasons backwards: 'If I enter the showroom and make a purchase the salesman wil sell me a lemon and my pay-off will be —6, which is less than zero — my pay-off in not buying a car at all. So of course I should not enter the showroom'. And he will not. We have thus a unique equilibrium of the game where no transaction occurs and where each party enjoys a pay-off — of nil. This is worse for both than the (non-equilibrium) outcome where a reliable car is sold and where the customer and the salesman enjoy @ and a respectively. A mutually beneficial transaction is thus unrealized.

QUESTION: How does signaling or reputation mechanisms break this lemons-market equilibrium in practice?

Diego Gambetta, Trust - Making and Breaking…, loc. 896

Buyers transact only when seller honesty exceeds a threshold [fact]

I conclude that if the seller's reputation for honesty is high — specifically if p exceeds 8 — the potential buyer will engage in a transaction. If it is low — specifically if p is less than 6 — he will not enter

DEFINE: p represents the probability threshold for seller honesty reputation that determines whether a buyer engages in a transaction.

Diego Gambetta, Trust - Making and Breaking…, loc. 922

Society underinvests in trust because its benefits spill over. [causal]

Trust, as economists have noted before, is a public good, a social lubricant which makes possible production and exchange (see for example Akerlof 1970; Arrow 1974). … The point is that if your trust in me increases it certainly benefits me. But if there are good reasons for this increase in trust it benefits you as well. This latter benefit I do not take into account when I try to build up my own reputation. This is the source of 'market failure' and, in particular, why there might typically be an underinvestment in trust formation.

XREF: Connects to public goods theory, externalities, and the free-rider problem familiar from economics of reputation and social capital.

Diego Gambetta, Trust - Making and Breaking…, loc. 934

Trustworthy exchanges can persist without binding commitments. [causal]

If the salesman is known to discount his future benefits at a low enough rate then it is the case that the outcome, where at each period the customer enjoys 1 —@ and the salesman a — that is, where at each date the customer enters the showroom and the salesman hands over a reliable car — is an equilibrium outcome even if there is no possibility of binding commitment of any sort.

DEFINE: Explains that a repeat-game equilibrium yields cooperation (reliable car each period) even absent enforceable contracts, contingent on the salesman valuing future payoffs sufficiently.

Diego Gambetta, Trust - Making and Breaking…, loc. 962

Reputation-building involves altering perceptions of one's character [definitional]

But while this example fits in part the notion of trust as I have defined it, it captures only one aspect of the idea of trust, namely that customers can trust the salesman to hand over a reliable car. It cannot convey the idea of the salesman trying to acquire a reputation for honesty — trying, through his behaviour, to alter people’s perception of what kind of person ‘he really is’. For notice that in the foregoing infinitely repeated game customers do not revise their opinion of him. They know he is dishonest (in the sense of having the pay-off structure of figure 4.1) and behaves honestly only because of the punishment (loss of customers) that will be meted out to him should he never renege.

DEFINE: Distinguishes bare trustworthiness from active reputation-building, where behavior changes others' beliefs about one's true character.

Diego Gambetta, Trust - Making and Breaking…, loc. 966

Reputation-building requires sacrificing short-term gains for honesty. [causal]

I think this is the right sort of framework to capture the idea that people invest resources for the purpose of building a reputation for honesty. The gains from honest behaviour are built directly into the model. The fact that the dishonest salesman builds his reputation by going against his short-term interests is an important feature to highlight. This is his investment.

DEFINE: Clarifies the economic concept that honest reputation is an investment: a salesman gains reputation by acting against immediate self-interest. Builds on: "Reputation-building involves altering perceptions of one's character"

Diego Gambetta, Trust - Making and Breaking…, loc. 1005

Committing costly signals lets honest agents distinguish themselves credibly [causal]

The first, and to my mind most serious, weakness of this model is that there is nothing which enables the honest salesman to distinguish himself from the dishonest one. Everything the former can do the latter can do as well. The dishonest type is the cancerous cell which 'acts' like the healthy one. It is here that the role of commitments can assume importance. If the stake is high enough the honest salesman will search for ways of persuading customers that he really is honest; he will be willing to spend resources to distinguish himself from his possible counterpart. This is not included in the foregoing model of reputation acquisition.

Builds on: "Reputation-building requires sacrificing short-term gains for honesty."

Diego Gambetta, Trust - Making and Breaking…, loc. 1006

Repeated games support multiple viable equilibrium outcomes. [causal]

The second weakness is that the strategies I sketch for the various participants are not the only credible ones. It follows that the outcome I describe is not the only viable one. There are other, equally credible, sets of strategies that result in outcomes which do not have this form of reputation acquisition, where transactions are not undertaken for a great many periods. In short, such repeated games possess more than one equilibrium outcome (see Fudenberg and Maskin 1986). There is therefore no guarantee that the one I have outlined will prevail. It is here that historical accidents may matter.

XREF: Relates to game theory concepts like the folk theorem and multiple equilibria in repeated games.

Trust is confident expectation of benign intentions in others [definitional]

Trust as a human passion may rest on close familiarity or massive social distance. Many have trusted their Queen (or Stalin) as implicitly as ever they have trusted their spouse or favourite sibling. The essence of trust as a passion is the confident expectation of benign intentions in another free agent.

Anarchism's defining flaw is its trusting view of dispersed power. [definitional]

It is helpful to present the deficiencies of anarchism as a theory not by stressing its exceedingly skimpy and implausible conception of the causal determinants of collective social life and its vicissitudes (a charge which can scarcely be denied), but rather by underlining its blatantly capricious views about the incidence of trust in human social relations. … What really marks anarchism out as a political theory is the judgement that dispersed coercive power either is in itself, or would be if instantiated, or could readily be caused to become, quite sufficiently trustworthy for the living of acceptable human lives. At its most optimistic anarchism simply consists in the universalization of trust towards all humans who are not themselves bearers of concentrated coercive power.

Realist power perspectives favor the powerholder's viewpoint [definitional]

This putatively realist perspective can be expressed in notably unapologetic terms — as it is, for example, by Thrasymachus in Plato's Republic, to some degree by Machiavelli in The Prince, and subsequently by Nietzsche. Thus presented, it is a perspective on power from the viewpoint of the powerholder (or of claques of intellectuals who more or less grovellingly identify themselves with the powerholder).

Established institutions demand less active trust than nascent ones [causal]

Where such institutions already exist and happen to be operating successfully it is reasonable for individuals to feel a stolid indifference towards the exertions which have brought them into being and to see them merely as occasions for current confidence. But where they have yet to be established the need for direct and exigent forms of trust is altogether more importunate.

XREF: Connects to institutional theory and social capital literature, where the difference between formalized trust and emergent trust parallels Ostrom's work on commons governance.

Human affairs elude contemporary understanding and influence. [contrarian]

Much of human life, plainly, is shaped by forces which no human beings at all at the time of happening genuinely understand; and even if a few select human beings did happen to comprehend those forces, they could scarcely significantly affect them.

Society's fate rests on how members use their freedom. [causal]

It is a view focused upon, and restricted by, human capacities: by the possible consequences of possible intended actions. It is within this (world historically, somewhat mole's-eye) view of human circumstance that the incidence of well-founded or ill-founded trust occupies such a key position. It does so because within this perspective what happens to a human society does depend both on the intelligence and practical skill of at least some of its members and on the use they elect to make of their freedom of action.

Trust mediates interactions when others act freely. [definitional]

Fundamentally, trust is a device for coping with the freedom of other persons (Luhmann 1979; and this volume). It is because of the phenomenological plausibility of this conception of trust that it plays such a prominent role in shaping collective life.

DEFINE: Trust is defined as a coping mechanism for the irreducible freedom of other people, not merely a risk calculation.

Diego Gambetta, Trust - Making and Breaking…, loc. 1146

Cooperation rests on expectations about others' conduct meshing. [definitional]

Rather, it depends (and in ways which perhaps extend with comparative ease to some other species) on the presence or absence of relatively well-founded expectations about the conduct of others — expectations which can serve, until too harshly violated, as premises for partially cooperative conduct of one's own. What the root conception consists in is a picture of the conditional meshing of mutual interaction.

DEFINE: Clarifies the 'root conception' of cooperation as conditional meshing of mutual expectations, not mere rule-following.

Diego Gambetta, Trust - Making and Breaking…, loc. 1158

Trust applies where knowledge of others' future actions is impossible. [definitional]

No one can know how another human being will act in the future. Trust is a policy apt for conditions where knowledge is unavailable, as in the case of the free acts of another person (in Locke's view) it will always remain. Trust does not have to be any more credulous or sentimental than the judgement of those who decide how to allocate it, though it will in practice, naturally, not be any less so either.

XREF: Connects to the distinction between risk (probabilistic, calculable) and uncertainty (unquantifiable) from decision theory — trust sits in the latter domain.

Political subjection makes citizens vulnerable to rulers' unknowable acts [causal]

For him the state was only an organizational system through which some human beings are enabled to act on behalf of (or against) others. … Men and women need in their rulers a power of agency which they can themselves only very marginally control. The subjects of every state are committed permanently by their political subjection to acts the character of which they cannot know and the consequences of which may embellish or devastate their lives.

XREF: Relates to Hobbes's Leviathan and theories of state sovereignty where subjects delegate agency they cannot control.

Political trust is a realistic judgment, not passive psychological submission. [definitional]

Trust in the relation between ruled and ruler is not a supine psychic compulsion on the part of the former. Rather, it is an eminently realistic assessment of the irreversibility of a political division of labour and a sharp reminder, from the former to the latter, of the sole conditions that can make that division humanly benign.

DEFINE: Reframes 'trust' in political relations as a contingent, reciprocal assessment rather than an emotional compulsion — a distinctive conceptual clarification.

Political legitimacy depends on constructing structures of well-founded trust [definitional]

Locke did not expect well-founded trust to be actualized at all frequently even in an essentially legitimate political society. But he thought that in political communities which were fortunate enough to be essentially legitimate the problems of political agency for all socially and politically active groups were always problems of how best to construct, reproduce, or repair structures of well-founded mutual trust.

Modern states depend on institutionalized divisions of political labor. [definitional]

Indeed what a modern state actually is, in large measure is a strongly institutionalized division of political labour, though not one which in any sense occludes the exercise of coercive force. The interesting question in modern political theory is not whether there is going to be a political division of labour (there is). It is the question of what forms that division is going to take and what are going to be the consequences of its taking those and not other forms.

Legitimate governance requires freedom of political speech and association. [causal]

There is no extant model of the most minimal plausibility which suggests that such legitimacy could be sustained other than momentarily and in extreme crisis without at least freedom of political speech and association and the right to organize and choose political representatives on the basis of the opinions which citizens actually hold.

Citizens should trust politicians' practical capacity over their intentions. [contrarian]

But by the same token it would also need to distinguish more sharply than is customary in modern political ideologies between trust in the good intentions of more or less professional politicians and trust in their practical capacities. Trust in either might often be an agreeable start. But if it is necessary to choose between the two, it is wiser in most circumstances (the more so, the more democratic or legitimate the polity in question) to opt for trust in practical capacity. Politics is not on the whole good for the character; and it is unlikely that there really are sound reasons for viewing the intentions of most of those who have devoted decades to it with unreserved trust. But this provides no reason fox welcoming the chance of being ruled by the well intentioned but hopelessly ineffectual.

Modern passion-based trust naively confides in existing institutions [definitional]

Here, especially, we can see how misguided it would be to hope to replace trust as policy (the properly sceptical choice of human political expedients) with trust as passion (in its characteristic modern form, an unreflective confidence in the efficacy and decency of existing institutions: state, party, government, union, or firm).

Nuclear knowledge is ineliminable and threatens its own knowers. [causal]

The first is that the knowledge of how to make these instruments of destruction is ineliminable in principle except by their large-scale use. This knowledge and the possibilities which it embodies are with us for as long as anything we could sensibly think of as our way of life, or civilization itself, is going to continue. The problem is not how to rid ourselves of this knowledge. We cannot unlearn it. The problem is to stop it getting rid of us. The second reason is that the level of threat, and its erratic but rapid intensification, are themselves a product of obtrusive structures of well-founded mutual mistrust.

Shared trust requires confronting risk directly and ranking it above competing anxieties. [causal]

Building the structures of mutual trust that would be required to diminish the urgency of the risk cannot be done by burying one's head in the sand, still less by encouraging others to do so. It can only be done by focusing more clearly on the scale of the risk itself and establishing a clear mutual understanding of the priority of the need to reduce it over the need to diminish other — often in their own terms equally realistic and indisputably grave — anxieties.

Trust only develops within a familiar world. [causal]

Familiarity is an unavoidable fact of life; trust is a solution for specific problems of risk. But trust has to be achieved within a familiar world, and changes may occur in the familiar features of the world which will have an impact on the possibility of developing trust in human relations. Hence we cannot neglect the conditions of familiarity and its limits when we set out to explore the conditions of trust.

Symbols are not signs, pointing to something else. [contrarian]

Symbols are not signs, pointing to something else. They presuppose the difference between familiar and unfamiliar and they operate in such a way as to enable the re-entry of this difference into the familiar. In other words, symbols represent the distinction between familiar and unfamiliar within the familiar world. They are forms of self-reference using the self-reference of form. In fact, symbols have developed as the successors of myth, replacing it first by symbolic interpretation and later by pure symbolism.

The concept of risk shifted meaning from blind fortune. [causal]

This discovery of 'risk' as a general feature of life — roughly replacing what had previously been known as fortuna — does not facilitate the task of religion, but it adds another dimension to human experience.

DEFINE: Clarifies the historical evolution of 'risk' as a concept that replaced 'fortuna' as a general feature of life.

Risk, unlike trust, depends on one's own prior conduct. [definitional]

The distinction between confidence and trust depends on our ability to distinguish between dangers and risks, whether remote or a matter of immediate concern. The distinction does not refer to questions of probability or improbability. The point is whether or not the possibility of disappointment depends on your own previous behaviour. Since 'risk' is a relatively new word, spreading from whatever sources into European languages via Italy and Spain only after the invention of the printing press, we may suppose that the possibility of making this distinction is likewise a result of social and cultural development.

XREF: The confidence/trust distinction is Luhmann's core social systems theory concept; risk as a modern cultural category also appears in Beck's risk society literature. DEFINE: Clarifies a definitional distinction between confidence and trust based on whether prior behaviour accounts for possible disappointment.

Liberalism shifts social expectations from confidence to trust. [definitional]

Seen from this point of view, political and economic liberalism attempts to shift expectations from confidence to trust. Insisting on freedom of choice, liberalism focuses on the individual responsibility for deciding between trust and distrust with respect to politicians, parties, goods, firms, employees, credit, etc. And it neglects the problems of attribution and the large amount of confidence required for participation in the system. Mobilizing trust means mobilizing engagements and activities, extending the range and degree of participation. But what does this mean, if people do not perceive a condition of trust or distrust but a condition of unavoidable confidence? They will not save and invest if they lack trust; they will feel alienated if they lack confidence.

DEFINE: Distinguishes trust (individual, discretionary) from confidence (systemic, unavoidable) as the conceptual core.

Such a theory would neglect the structural complexity of social systems as an intervening. [fact]

Moreover, we have to acknowledge that the relation between confidence and trust is not a simple zero-sum game in which the more confidence is given the less trust is required and vice versa. Such a theory would neglect the structural complexity of social systems as an intervening variable. But a social evolution which achieves increasingly complex societies may in fact generate systems which require more confidence as a prerequisite of participation and more trust as a condition of the best utilization of chances and opportunities.

Trust involves self-reference while risk arises from our own choices [definitional]

The case of trust is very different and requires quite another type of self-reference. It depends not on inherent danger but on risk. Risks, however, emerge only as a component of decision and action. They do not exist by themselves. If you refrain from action you run no risk. It is a purely internal calculation of external conditions which creates risk. Although it may be obvious that it is worth while, or even unavoidable, to embark on a risky course — seeing a doctor, for instance, instead of suffering alone — it nevertheless remains one's own choice, or so it seems if a situation is defined as a situation of trust.

Builds on: "Risk, unlike trust, depends on one's own prior conduct."

The printing press blurred the familiar-unfamiliar distinction in society [causal]

These considerations lead to the hypothesis that the printing press has completely changed our modes of coping with the unfamiliar. The distinction of familiar and unfamiliar becomes blurred; the religious technique of reintroducing the unfamiliar into the familiar through symbolization loses its former potence. There is no longer any need to distinguish symbolon and didbolon, good and bad forces, at a cosmological level. These schemes are replaced by the question of whether knowledge and power are used in a positive or a negative way, given particular interests. Thus confidence and eventually trust are the decisive issues, and familiarity survives as a purely private milieu® without function for society as a whole.

Modern societies shift people from fixed roles to multiple functional systems [causal]

A second major change comes about when the predominant type of social differentiation shifts from stratification to functional differentiation. People® are no longer placed in a fixed social setting but must have access to all functional subsystems of the society on which they simultaneously depend. Structures become contingent; the law can be changed, if not by statute then by judicial practice (Horwitz 1977). The fluctuations of the economy are no longer thought to be limited by the boundaries of 'just prices'. Science surprises the public with new discoveries and new theories as a matter of routine. !° Essential structures and territorially bounded cultural entities are largely displaced by timelimited entities such as fashion and style.

Modern systems require confidence rather than personal trust. [definitional]

Trust remains vital in interpersonal relations, but participation in functional systems like the economy or politics is no longer a matter of personal relations. It requires confidence, but not trust.

Lacking trust in systems alters people's important decisions. [causal]

The large functional systems depend not only on confidence but also on trust. If there is a lack of confidence there will also be a diffuse sentiment of dissatisfaction and alienation or even anomie. This may have no immediate impact on the system. If trust is lacking, however, this changes the way people decide about important issues. Trust, as may be recalled, is an attitude which allows for risktaking decisions. The development of trust and distrust depends on local milieu and personal experience.

Trust and its destruction require concrete settings with visible risk decisions [causal]

These conditions may be extended by television culture, for instance in the case of political leaders. The testing and control of trust and the continuing perception of those symbolic events that eventually destroy it require a relatively concrete setting. They depend on a previous structural reduction of complexity. Moreover, they require a visible relation to one's own decisions about accepting a risk.

Socially extensive trust only arises within aristocracies. [causal]

I want to explore what could be thought to be three ironic and even disquieting truths about trust.! I want first to argue that a socially extensive trust, that is to say, something more than trust between friends, cannot be created except in and by what I call 'aristocracies'; second, that having been so created, there is good reason to believe that the aristocrats will undermine it; and therefore, and third, that if trust is to be maintained, this will have to depend on conditions which are external to the social arrangements in question or which, if internal to them, might at first sight seem to be conditions that pre-empt anything one would want to call 'trust' at all.

Society's quality of persons is measured by their adherence to a governing code. [definitional]

I do not by this mean, or do not only mean, a society bound together by a militaristic code of honour and propped up by a toiling mass in bondage and felt boots. I mean more generally a society which turns on a code, in which the quality of persons is measured by the extent to which they observe this code, in which there can, that is, be said to be 'persons of quality' — a society, in the familiar phrase, of 'virtue and honour'.

XREF: Connects to discussions of honor cultures and social stratification — the notion that personhood and worth are defined relationally through code-observance, echoing work on honor-shame societies and Weber's status groups.

Appearances of virtue can mask betrayal in any society. [contrarian]

I trust my friends, but just as there can be treachery in a kiss, so too there can be betrayal in an honourable mien. It has repeatedly proved too much to ask of persons of quality that they always remain so in those societies, which are all the societies there are, in which people will be presented with conflicting claims. … I see no reason to trust trust just as trust. And so, I see no reason to trust its markers. Given the syntactical and sartorial corollaries of aristocracies, I see no reason to trust someone who speaks and dresses too well; and given the sartorial corollaries of the new socialist person, I see no reason to trust one who dresses with too ostentatious a drabness either.

High wages and division of labor secure the poor from arbitrary charity. [causal]

The Adam Smith I have in mind is the one illuminatingly reconstructed by Istvan Hont and Michael Ignatieff (Hont and Ignatieff 1983: 1-44). This is the Smith who argued that if one were to go over to an economy of high wages and a high division of labour, one would not only generate more wealth; one would also insure the poor against the capricious charity of the rich; one would replace an unpredictable provision by persons of quality with a predictable if minimal quantity; one would replace trust, which was not self-reinforcing, with a mutual interest in the results of the pursuit of self-interest, which would be.

Self-reinforcing systems cannot guarantee supporting systems will function. [fact]

Moreover, although these self-reinforcing systems do depend on other systems to support them - that was Hirschman's point — they do not in fact guarantee that those ancillary systems will work. They will work, of course, if pecuniary incentives are already in place. But it is part of the point of the argument that such incentives may not exist.

Backward linkages can entrench the very patronage relations they aim to overturn. [contrarian]

And most severely of all, even if the backward linkages do link, either in the way that Hirschman envisaged, or in some other way, they can do so in such a way as actually to strengthen those social and political relations — the hierarchical relations of patronage and so of 'corruption' that Hirschman, like Adam Smith, so disliked — which it is their purpose to override.

Despotic systems destroy information quality by politicizing all acts. [causal]

The most fundamental reason [why despotic rulers are unable to achieve their goals] is found in the lack of reliable information. ... The flaw of the system is that all acts tend to have an immediate political significance, which means that information degenerates into informing and so becomes worthless for planning purposes. Or else the information is offered that the informant believes his superiors want to hear, even if they insist on information that reflects the world as it is rather than the world as they would like it to be.

South Korea's KCIA exploited invasion fears to amass vast power. [causal]

Exploiting the persistent fear of imminent invasion from the DPRK, a fear encouraged by the Americans, and assiduously gathering information on a large number of putative subversives in a wide variety of places in society, the KCIA had in turn exploited the preexisting distrust in the society to the government’s advantage. Indeed, the KCIA’s power may have exceeded that of any comparable agency in any country in the world, even, pace Elster, the KGB.

State-led economic cooperation lacks durable trust and may collapse. [speculation]

Nevertheless, even if it is conceded that the government of the ROK has in this way overcome what might otherwise have been an economically debilitating vicious circle, it cannot be said that it has created trust. On the contrary. And it is indeed perfectly possible that if and when the present pattern of rule changes in the country, as Chun Doohwan intends it to do in 1988, existing cooperations and the successful economic organization which depends on them could dissolve or even collapse.

Elite-created social trust inevitably erodes under elite influence. [causal]

I have argued that a socially extensive trust cannot be created except in and by what I have called 'aristocracies'; that having been so created, there is good reason to believe that the aristocrats will undermine it; and that if trust is to be maintained, this will have to depend either on conditions which are external to the social arrangements in question or on strategies which are internal and which, although perhaps directed by what could be called an 'aristocracy', might at first sight seem to preempt anything one would want to describe as 'trust' at all.

Functional trust requires an external authority to establish initial conditions. [causal]

In their different ways, the failures of backward linkage even in high-technology systems, the changes in agricultural practice and political affiliation in northern India, and the developmental successes of South Korea, each suggest that whatever may eventually result, a self-reinforcing and functional trust may not be able to generate itself, but may require something analogous to an 'aristocracy' to impose the initial conditions of its generation.

Trust can be deliberately engineered by cultivating distrust [contrarian]

The second qualification, most evident from the example of Korea, is that it may be possible deliberately if deviously to create trust, which cannot always therefore be seen as a 'by-product', as Elster claims; and that at least one way of doing so is the way that Elster, after Tocqueville, does not believe is possible. If this in turn is right, it would seem to follow that in some conditions some 'aristocracies' — a political party, for instance, or an army — can create trust after all, and can do so by creating distrust.

Enlightenment theorists saw trust as sustaining all political association. [definitional]

Trust — fides — was also, for anyone reared (as all eighteenth-century Italian theorists were) on Machiavelli, the necessary condition of all political association. Trust, wrote Doria in his Della vita civile of 1710, 'is the sole sustenance of states and leads to their stable maintenance' (1852: 352). Fede here is a purely social and a visibly public virtue. It is, in Genovesi's telling phrase, fede pubblica.

Spanish honour was male self-love vested in women. [definitional]

In the sense Doria used it when describing what he, and indeed most European contemporaries, regarded as the single defining characteristic of Spanish culture, it implied the existence of a self-love vested in, and consequently at risk through, the persons and objects -and most particularly the persons viewed as objects, that is, the women -by which a man (for a woman's honour is merely a repository for the man's) is surrounded.

Public honour requires a witness and external relationships. [definitional]

But there is also that other kind of honour which derives from Aristotle's account in the Nichomachean Ethics of 7.un (book 1, chapter V, 5). This is public, in that it requires a witness, and thus implies a relationship between two or more parties and with persons outside the kin group.

Honour and virtue substitute for coercion in enforcing agreements. [causal]

This understanding of honour —the sense in which the term is used in such phrases as 'honouring one's bond' — is, of course, a crucial component of trust. As Genovesi said, onore e virtu (honour and virtue), in the absence of any effective coercive mechanism, can be the only guarantors of a debtor's reliability. But, as we shall see, no virtue is possible in a society of honour understood in the first sense.

Counterfeiting crimes that undermine public trust merited harsher punishment than theft. [causal]

Counterfeiting in particular was, Genovesi pointed out, punished with the utmost severity even among ‘barbarous nations’ such as the Incas, since it threatened the social bonds which held together the entire community (1803: 102-9). In Naples, however, a man might be executed for theft, a crime whose consequences were hardly to be compared with the loss of life, but let off with a fine for an act which, in Doria’s view, ‘offends against public trust [fede pubblica] and thus against the entire republic’

With the collapse of those conditions on which true commerce depends. [fact]

With the collapse of those conditions on which true commerce depends, trade became a question of mutual deception. Bonds and even money, since so much of it was false, were no longer freely accepted and the Neapolitans were reduced to the condition of the savages described by Genovesi who will only give with the right hand if they simultaneously receive with the left (1803: 70-1). As a consequence of massive degrees of mistrust loans were only made at exorbitant rates of interest, bankrupting all but the richest of merchants and leading to the widespread belief that a predominance of ‘idle money’ was the source of the kingdom’s ills

Trust extends family loyalty to strangers across society. [definitional]

For Doria and Genovesi trust is the basis of the well-ordered republic. It is, in short, the motive for a man to behave towards members of the society at large in much the same way he behaves towards members of his own kin group; or, at least, it provides strong reasons why he should not ~— except in purely private concerns — privilege that group over any other.

Well-ordered republic ethics underlay both Calvinism and capitalism. [connection]

Quentin Skinner has argued forcefully that the kind of humanistic ethics Doria and Genovesi were attempting to revive, which set this idea of the ‘wellordered republic’ at the centre of all social relations, employed a similar conceptual vocabulary to Calvinism; that — to put it the other way round — the social ethos of Calvinism can be seen to constitute a special case of classical republicanism (Skinner 1974a; 1974b). If we accept this view then many of the problems historians have had with Weber’s famous thesis on the association between Calvinism and the rise of capitalism disappear, since it might be maintained that it was not a specifically Calvinist or Puritan work ethic which encouraged economic take-off in the Protestant cities of the seventeenth century, or Christianity itself in the medieval cities of north and central Italy, but the secular ethic of classical republicanism.

XREF: Directly engages Weber's Protestant ethic thesis, reframing it as a special case of classical republicanism rather than a distinctively Calvinist work ethic.

It constitutes the code of honour which is familiar to all. [fact]

This method is to gang up in a group, which in effect hangs up a notice saying: anyone who commits an act of aggression against any one of us must expect retaliation from us all, and not only will the aggressor himself be likely to suffer retaliation, but his entire group and all its members will be equally liable. And this notice is in effect posted by the very culture which pervades pastoral societies. It constitutes the code of honour which is familiar to all. So the gangs themselves do not need literally to put an announcement in the press or even on their tent. The culture, or specifically the obligation of feud which is inherent in it, does it for them.

Functional arguments wrongly assume needs automatically create their solutions. [causal]

This is a teleological or 'functional' argument, of course, open to the objection that the need for the cohesion of social groups will not automatically engender that cohesion. In the absence of a designer and creator, the favourite logical substitutes are our old friends, natural selection and rational foresight. Presumably each of them operates, though no one really knows in what proportion.

QUESTION: The unresolved proportion question — how much social cohesion comes from natural selection versus rational foresight — seems genuinely open and unexplored here.

Treason maintains equilibrium in tribal societies like prices do in markets. [causal]

Treason is built into the working of such a society and its culture and, if carried out properly and in due form, no stigma attaches to it. This kind of society could not possibly function without treason. Treason within it performs the same role that price changes perform in a market society. It helps to maintain equilibrium through realignment. Just as a rise or fall in price ideally redirects resources to the point at which they are optimally deployed, so a realignment — treason, if you will — restores balance to the segmentary tribal world. An outnumbered clan Cl, unable to hold its own within tribe T1, will leave T1 and join T2.

Cities depend on tribal outsiders for political governance. [causal]

Given that the society as a whole needs a level of production and trade which presupposes urban centres, and given that urban centres (clusters of specialists) are quite incapable of social cohesion and hence of political and military effectiveness, what is to be done? What is done is that the tribes provide cities with rulers: the state is the gift of the tribe to the city. Economically, the tribe needs the city: politically, the city needs the tribe.

Governance requires never having submitted to it yourself. [contrarian]

The rulers in the citadel are the people who acquired the capacity or the tendency to trust each other, and hence to be cohesive, by being ungoverned. If you wish to govern, you must never have submitted to government yourself. Only the ungoverned condition of the savannah, desert, and mountain, engenders the kind of tribal group whose members trust each other and display cohesion.

Governing rulers gradually lose the cohesion that won them power. [causal]

This and this alone makes such groups capable both of government and self-government. Consequently, from time to time, some of them occupy the citadel. Once they are there, and this of course is the best known part of Ibn Khaldun's theory, they gradually lose that very cohesion they acquired when they were ungoverned, and which enabled them to rule. In his schematized version, this takes about three or four generations. They lose it in the process of governing and of benefiting from the privileges of government.

Sacred customs reinforce group identity even beneath official uniformity. [causal]

In the politically organized, self-administering countryside, under the cloak of a nominal adherence to an exclusive unitarianism, there is in fact a Durkheimian religion which works by providing social punctuation in space and time. The sacred is incarnate, with a local habitation and a name. It helps to define groups, define their status, define their boundaries: it reinforces their cohesion.

Urban elite Islam resembles doctrinal unitarianism, unlike tribal forms. [definitional]

In the towns, at least at the top, there is something which does more closely approximate to the Islam of the learned theologians: an exclusive unitarianism with a hidden deity, which proscribes mediation, and so theoretically recognizes no clergy, and which preaches an ethic of rules rather than of loyalty. It neither expresses the cohesion of groups, nor provides an idiom of treachery.

Collective oaths express group loyalty, not factual accuracy. [definitional]

The difference in style is well reflected in how you testify at court. The country folk testify in groups in collective oath. Under proper Muslim law, you testify as an individual. The collective oath of the tribesmen is really an expression of commitment to the group, an expression of a willingness to bear responsibility with it. It is not a testimony to matters of factual accuracy, which is the purpose of the oath offered by the individual in an urban trial.

Patronage networks replace kin groups as the basis of safety. [causal]

A person's safety no longer lies in the strength of his kin group, but rather in having a friend at the nearest district office, who in turn has a friend at the provincial capital, who has a friend at the national capital.

Modern Muslim revival favors direct believer-deity relations without mediators [causal]

The most significant cultural event in the Muslim world of the past 100 years has been a very major Reformation, a shift from mediationist religious brokerage to a symmetrical relationship between the deity and believers in conformity with the old, but previously unpractised, high theology. Suddenly religion is egalitarian and symmetrical, centralized, with an exclusive single deity and without mediators.

Islamic authorities tolerated but contained trust-generating social groups [fact]

In the Islamic model the central authorities were not positively hostile to trust on any theological principle, but were simply intolerant, within the very considerable limits of their capacity, of the emergence of coherent trust-engendering groups which would pose a threat to them. They would keep such groups at bay, but they could not destroy them.

Religion enables communication between tribal and urban social groups. [causal]

Religion provided an idiom in terms of which the various elements of the total society could communicate with each other. It provided the terminology for both tribal trust and urban fear. It could intermittently help tribal cohesion to extend its scale, and to revitalize the polity by providing a new set of rulers.

Tribal trust emerged from statelessness while urban order rested on fear. [causal]

Tribal life, conditioned primarily by lack of government and the consequent need for cohesion, was the only source of a certain kind of trust, which bound men in groups, even though it was also haunted by the possibility of treachery. In the towns, there was specialization, no trust, and order based on fear.

Equilibrium describes an outcome agents lack incentives to alter. [definitional]

The use of the term equilibrium, therefore, is not just an analogy but is adopted here in the sense of a state of affairs in which all or most agents, in spite of-what they may think of the collective outcome, have not found adequate incentives to behave differently and to change that outcome in any significant way.

Through this fictional account, by which Tocqueville manages to convey his reflections on the journey, we begin to grasp some of the elements of the peculiar process of adjustment to — rather than rebellion against — domination which to different degrees involves both Naples and Sicily: the absenteeism of an aristocracy lured by the pleasures and servility of the court; the predominance of private over public concerns, of duplicity, cunning, and favour over merit; and the fashion for crime and murder, which have become habitual and are even felt to be legitimate

Mafia-averse emigration unintentionally concentrates and strengthens remaining mafia power. [causal]

A wide range of evidence (Arlacchi 1983) suggests that, on the margin, people who migrate do so also because of the mafia. Given that 'mafia-averse' people tend to migrate more frequently, the degree of opposition is likely to decrease and the power of the mafia to increase. The effects of migration are clearly unintended, because those who migrate do not do so in order to enhance the force of the mafia (although they may of course recognize those effects).

Authoritarian state monopolies suppress local mafia organizations [causal]

Fascism suppressed the mafia where democracy accommodates it [contrarian]

Italy did once have a power which was largely independent of the mafia, or at least of the social strata supporting it, and which did contribute to a partial undoing of the mafia (Duggan 1985): this was of course the Fascist regime. In contrast, democracy, by its very nature, has to rely for consensus on larger parts of the population. Thus the temptation to come to terms with those who hold a monopoly of people's votes, regulate the dispensation of political trust, and somehow guarantee local 'law and order', has been strong, and in several instances has proved irresistible.

Human cooperation rests on four distinct motivating mechanisms. [definitional]

The mechanisms which motivate cooperation in any form of human endeavour, as Bernard Williams explains elsewhere in this volume, comprise four basic elements: coercion, interests, values, and personal bonds. People, that is, may decide to cooperate (1) for fear of sanctions; (2) because cooperation enhances their mutual economic interests; (3) because they have general reasons, whether cultural, moral or religious, to believe that cooperation is good irrespective of sanctions and rewards; and finally (4) because they are related to one another by bonds of kin or friendship.

Predatory reputation-building proves strategically rational for maintaining monopolies [contrarian]

Many mafiosi have begun their careers with violent acts (Hess 1973; Arlacchi 1983), but have subsequently relied on the reputation with which such acts provided them: 'basta la fama' wrote Franchetti (p. 104), in line with some of the most advanced game theory (see Milgrom and Roberts 1982, who show that, contrary to the standard economic claim, 'predatory practices' to maintain a monopoly are not irrational if reputation and future challengers are taken into account).

Victims of extortion gain benefits from their extortionists' protection [causal]

The distinction between a damage avoided and a benefit gained is up to a point artificial. [In most cases] the line that separates them is impossible to determine, or rather it does not exist in human feeling. When evildoers intrude on and dominate most social relationships, . . . the very act that saves one from their hostility can also bring their friendship with all its associated advantages (p. 129). … The violence of extortion and the self-interest of the 'victim' tend to merge and to provide an inextricable set of reasons for cooperation: the advantage of being a 'friend' of those who extort one's money or goods is not therefore simply that of avoiding the likely damages that would otherwise ensue, but can extend to assistance in disposing of competitors, or protection against the threats of isolated bandits, and against the risk of being cheated in the course of business transactions.

Distrust of being cheated can collapse market exchange entirely. [causal]

We know that the absence of trust in business has a devastating effect: a high expected probability of being cheated (of being saddled with a 'lemon') may lead to the non-emergence or even to the collapse of market exchange, especially in those cases where asymmetric information - concerning the quality of the goods exchanged - is relevant (Akerlof 1970; Dasgupta, this volume).

Trusted intermediaries with coercive reputations can guarantee exchange between strangers. [causal]

The mafioso, by means which are left unclear but which presumably involve his reputation for toughness, seems capable of deterring the seller from handing over a 'lemon'. Without that protection the coachman is truly at risk, for he is indeed, as it were, saddled with a bad horse. … More difficult to interpret is the fact that the seller too gives the mafioso a tip. This could suggest, in line with Dasgupta's argument (this volume), that with respect to that particular transaction the protection the mafioso offers is really a public good which benefits both sides. If he did not act as guarantor the exchange would not take place at all, for the potential buyer would be deterred from entering the transaction for fear of getting a bad deal. The seller's tip, in other words, might reflect the price he is prepared to pay to be trusted.

There remains the zone of free-floating social relationships formed by choice in the expectation of mutuality. The most neutral term for this zone is association, but its strongest form of expression is friendship, the negotiated order of free individuals joined by affection and shared experience rather than by legal sanction or the ties of blood.

Debt chains allow migrants to deflect creditor pressure outward [fact]

I noticed that something like chains of debt were commonplace. Each migrant made and received loans (including traders' credit). If a man came into a windfall — a stolen wallet or a back-dated pay rise — he was as likely to lend the money as to pay off existing debts. This meant that when he was being dunned by a creditor, he could pass on the pressure to one of his debtors. There is an analogy with traditional bridewealth transactions where in-laws typically chase an infinitely regressive chain of debt in order to retrieve an outstanding cow. Another metaphor for this process, besides that of a chain, might be the ripples caused by a stone dropped into a pool.

Trust means betting one's actions on others' risky behavior. [definitional]

I agree with the emphasis placed by both Partha Dasgupta and Niklas Luhmann (in this volume) on the importance of personal agency in defining trust. Thus Dasgupta identifies trust as an expectation about another person's actions which influences our own actions before we have full knowledge of the outcome; and Luhmann exposes to full view the distinction between personal and impersonal social organization. Clearly trust is the predication of one's own actions on actions of others which bear an identifiable risk of turning out unfavourably.

Urban migrants lack the institutional foundations for market contract exchange. [causal]

The Frafra migrants face the problem of establishing economic forms, durable relations of partnership and hierarchy, in the city slum. Three basic models for how to go about this present themselves. The most obvious and apparently profitable of these is the contractual ethos of the civil society they think they have joined, that is individualism, rationality, market, impersonal law — the bourgeois package of city life. Here economic relations are in principle entered into freely and by choice, but the contract imposes binding obligations sanctioned by state law. There are several reasons why this does not generally work. State law does not apply except in the form of occasional punishment. Markets are erratic and the substantive conditions of rational calculation are largely absent.

Customary kinship institutions weaken when migrants relocate to cities [causal]

Looking for some alternative form of guarantee, the migrants turn to the antithesis of modern civilization, their own customary moral institutions founded on the identities of kinship, descent, and family, reinforced as they are by a common language and religion, by the certain obligations of birth and community. This option too is fallible. The institutions do not travel en bloc to Accra, and some of the important public sanctions of domestic hierarchy are missing: lineages, ancestor worship, the security of their homeland. The migrant community is an egalitarian brotherhood of floating young men anchored in the patronage of a few resident big men. It is not closed or powerful enough to shore up the authority and reliability of kinsmen.

Firms subcontracted production while retaining design of firm-specific components. [fact]

What I was observing, however, was different. It was a shift to subcontracting on a permanent basis for such standard operations as turning, milling, and drilling. It allowed the firms to avoid making investments in up-to-date machine tools and was frequently the occasion for a reduction in capacity, with some existing plant being sold off. While the general type of operation subcontracted was not specialised or specific to the particular firm in question, the design and specifications of the components were. Thus it was not a case of substituting in-house production for standardized components available in the market: rather, components were being machined (turned, milled, etc.) by subcontractors according to firm-specific plans produced in the design offices of the client firm.

French layoff restrictions encourage temporary and loaned labor arrangements. [causal]

This form of subcontracting is encouraged by the rigid restrictions French legislation places on laying off workers. During the 1970s these restrictions spawned a proliferation of temporary help agencies whose employees do not benefit from the same protective legislation. Another common arrangement is the use of so-called intérimaires, permanent employees of one firm with an excess supply who are loaned on a temporary basis to a firm facing a capacity constraint.

Market relations between firms resemble moral partnerships built on trust. [contrarian]

Cost considerations, then, dictated the initial switch from in-house production to reliance on the market. Further discussion showed, however, that these evolving market relations were a far cry from those of the standard textbook, where 'faceless buyers and sellers meet for an instant to exchange standardized goods.' By 1984-85 the firms had begun to use a suggestive word to describe their relationship to these new subcontractors: partnership (partenariat). In the course of conversations in which I myself participated, other equally emotive terms evoked the nature of interfirm relations: the importance of loyalty (fidélité); the existence of a moral contract (contrat moral); and the need for mutual trust (confiance mutuelle).

Trust requires voluntarily increasing one's vulnerability to another party. [definitional]

Trusting behaviour consists in action that (1) increases one's vulnerability to another whose behaviour is not under one's control, and (2) takes place in a situation where the penalty suffered if the trust is abused would lead one to regret the action. In economic terms this implies that the action would not be taken in the absence of trust because the expected net benefit is lower than if some alternative is chosen. In short, there is no best strategy independent of trust.

Diego Gambetta, Trust - Making and Breaking…, loc. 2503

Trust only becomes relevant when others can behave opportunistically. [definitional]

Firstly, trust presupposes decision-making in a situation of risk, where the risk is attributable to the strategic behaviour of others or to the possibility that they will behave opportunistically. By opportunistic behaviour I have in mind not only such blatant forms as stealing and lying, but also more subtle techniques such as withholding information in an effort to confuse. As Dasgupta (this volume) has noted, the possibility of such behaviour is a necessary condition for the question of trust to arise. If all people are invariably honest, doing their best to fulfil their commitments, then there is no problem of trust as I have defined it.

DEFINE: Defines trust conditionally: it presumes risk from others' strategic or opportunistic behavior, including subtle forms like withholding information. XREF: Connects to the broader trust literature, including Dasgupta's work on risk and commitment, foundational in social capital theory. Builds on: "Trust requires voluntarily increasing one's vulnerability to another party."

Avoidable risk distinguishes genuine trust from forced reliance [definitional]

Secondly, the action and hence the risks are avoidable: one does not have to engage in trade with another firm (although this implies forgoing the potential benefits of trade). Being able to avoid the relation is fundamental. If you could not, you might say something like: 'I have no choice but to trust this person, institution, etc.' Clearly, there being no choice, we need not invoke trust to explain our behaviour. Of course, as Luhmann (this volume) points out, whether or not a relation is seen to be avoidable is often highly subjective, and presumably varies in accordance with the structure of institutions and political power.

Transaction costs resemble friction in their practical significance [definitional]

I would like to suggest that the transaction cost literature (associated notably with Williamson 1975; 1985) can tell us something about the role of trust in the economy. As the term 'transaction cost' suggests, this literature is concerned with the organizational implications of the costs of making a transaction. This includes not only the cost of reaching an agreement satisfactory to both sides, but also that of adapting the agreement to unanticipated contingencies and of enforcing its terms. … The relation of transaction costs to the economy parallels that of friction to a physical system: it is often ignored in formal models but is none the less of great practical significance.

XREF: Connects to the reader's likely familiarity with Williamson's work and the analogy to physical friction as an explanatory device in economic modeling.

Trust reduces transaction costs by lubricating economic exchange. [causal]

If transaction costs are thought of as friction in the economy, then trust can be seen as an extremely effective lubricant. To quote Arrow (1974: 23): 'It saves a lot of trouble to have a fair degree of reliance in other people's word.'

DEFINE: Introduces trust as a friction-reducing mechanism in economic terms, framing it metaphorically as lubricant against transaction cost friction. Builds on: "Transaction costs resemble friction in their practical significance"

Bounded rationality makes comprehensive contracting fundamentally imperfect. [causal]

In conclusion, then, once firms are locked into a relation, trust is essential. The need for trust can be circumscribed through the efforts of the parties to engage in comprehensive contracting. But the limits to our rationality in a world where surprise is inevitable ensure that such efforts will be imperfect at best. Trust cannot be disposed of entirely.

Client firms minimize trust reliance through safeguards like multiple tenders. [fact]

The first point to be made is that there is extensive use of safeguards by client firms to minimize the possibility of being the victim of opportunistic behaviour and hence the need to rely on trust. There is an Italian saying which captures much of the sentiment: 'It is good to trust but it is better not to trust.' First, client firms prefer to solicit tenders from a minimum of three subcontractors in order to preclude an opportunistic distortion of production costs. They also prefer to split an order between a minimum of two subcontractors so that if difficulties develop with one it is possible to switch to the other. This practice may, of course, entail a loss of potential scale economies depending on batch size.

Reputation signals trustworthiness but cannot substitute for experience. [causal]

The evidence suggests that reputation is important but no substitute for experience. My information pertains primarily to the client’s perception of the subcontractor and I would not want to exclude entirely the likelihood of asymmetry here. The client firms are comparatively visible, being prominent members of the Lyons engineering community and in most cases larger than the subcontractors. My interviews suggested that they are acutely aware of their reputation for reliability. When asked how they signalled their trustworthiness to potential subcontractors, they invariably referred to this.

Economic trust in subcontracting rests on something beyond friendship. [contrarian]

It would be difficult to explain how trust could be present as often as it is in subcontracting if it were to depend on sentiments of friendship. If this were true, we would have to adopt in the economic sphere Hawthorn's (this volume) conclusion in the political: that any attempt to produce trust which was not in fact an attempt to produce something else, something self-reinforcing, must fail. It seems implausible to entertain feelings of friendship for someone when it is realized that he or she is acting in a friendly way solely for the purpose of facilitating an economic transaction.

More cooperation is not always desirable, even if basic cooperation is necessary. [contrarian]

'According to the trite observation' — Adam Smith wrote — 'if there is any society among robbers and murderers, they must at least. . . abstain from robbing and murdering one another' (Smith 1976: 86; see also Saint Augustine in Dunn, this volume). This 'trite' observation serves a double purpose: it reminds us that basic forms of cooperation are inevitable if a society is to be at all viable, but it also points out, perhaps unwittingly, that there are instances of cooperation — notably those among robbers and murderers — that we may want to dispose of rather than improve. We may want /ess cooperation (and trust) rather than more, especially among those who are threatening us, and whose cooperation is a hindrance to ours.

Trust arises from our limited knowledge of others. [definitional]

The condition of ignorance or uncertainty about other people's behaviour is central to the notion of trust. It is related to the limits of our capacity ever to achieve a full knowledge of others, their motives, their responses to endogenous as well as exogenous changes. Trust is a tentative and intrinsically fragile response to our ignorance, a way of coping with 'the limits of our foresight' (Shklar 1984: 151), hardly ever located at the top end of the probability distribution. If we were blessed with an unlimited computational ability to map out all possible contingencies in enforceable contracts, trust would not be a problem

The rulers of a slave society — assuming that they do not mind what. [contrarian]

The rulers of a slave society — assuming that they do not mind what slaves think — can restrict their trust in the slaves and in the viability of their society to the belief that the slaves are not going to commit mass suicide. They simply trust to the fact - not invariably borne out by historical evidence — that most humans, even under extreme conditions, have a preference ordering which ranks life before death. Here, trust must be understood in the limited sense of trusting the effectiveness of coercion as a motive for cooperation

Diego Gambetta, Trust - Making and Breaking…, loc. 2725

Trust requires the trusting party's own freedom to refrain. [definitional]

The freedom of others, however, is not by itself sufficient to characterize the conditions in which the issue of trust arises. Our relationship with people who are to some extent free must itself be one of limited freedom. It is a freedom in the sense that we have to have a choice as to whether we should enter into or maintain a potentially risky relationship: it must be possible for us to refrain from action. If it were only others who enjoyed freedom, while we had no alternative but to depend on them, then for us the problem of trust would not arise: we would hope rather than trust

DEFINE: Clarifies that trust presupposes mutual limited freedom — the option to refrain, otherwise one hopes rather than trusts.

Diego Gambetta, Trust - Making and Breaking…, loc. 2727

Trust rests on the belief that others won't harm us. [definitional]

In conclusion, trusting a person means believing that when offered the chance, he or she is not likely to behave in a way that is damaging to us, and trust will typically be relevant when at least one party is free to disappoint the other, free enough to avoid a risky relationship, and constrained enough to consider that relationship an attractive option.

Strong action pressure reshuffles beliefs to justify itself. [causal]

If the pressure to act is great even when the trust threshold is lower than 0.50 — when we verge, that is, on distrust — the tension between action and belief can generate, by means of wishful thinking and the reduction of cognitive dissonance, a deceptive rearrangement of beliefs. Thus there are those who distrust entire categories of people except the member of that category with whom they have a special relationship.

Confidence resembles hope more than trust when blind. [definitional]

Confidence, in the sense defined by Luhmann in this volume, might be described as a kind of blind trust where, given the constraints of the situation, the relationships we engage in depend or are seen to depend very little on our actions and decisions. In other words, confidence may also issue from wishful thinking and the reduction of cognitive dissonance; it would then be more akin to hope than trust. We still know little, though, about how a certain level of trust is or can be achieved and promoted.

DEFINE: Distinguishes Luhmann's sense of confidence from trust, characterizing it as blind, hope-like, and grounded in wishful thinking and cognitive-dissonance reduction. XREF: Connects to trust/risk literature (Luhmann) and could tie to cognitive dissonance theory from social psychology.

Trust is a by-product, not a precondition, of good systems. [contrarian]

Indeed, some amount of trust must be present in any complex economic system, and it is far from inconceivable that systems with a higher level of general trust could come about. It would be risky, however, to make higher levels of trust into a cornerstone of economic reform. We may hope that trust will come about as the by-product of a good economic system (and thus make the system even better), but one would be putting the cart before the horse were one to bank on trust, solidarity and altruism as the preconditions for reform.

Trust is not a depletable resource but can be cultivated. [contrarian]

The first is that trust is not scarce in the sense of a resource that is depleted through use; the second that although it is often a by-product, this is not always so; and the third that there are extremely important cases where self-reinforcing arrangements acting on interests are either too costly (or unpleasant) to implement, or unavailable in the first place because trust is in excessively short supply.

Optimal cooperation emerges without deliberate manipulation of arrangements. [causal]

The most economical strategy of all is not that of not having to bank on trust, but that of not even having to bank on manipulating cooperative arrangements, on the assumption that rational — in the sense of optimal - cooperation evolves by itself.

QUESTION: What conditions allow rational cooperation to evolve by itself rather than requiring deliberate structuring?

Random signals can evolve into stable cooperative arrangements [causal]

Take, for instance, the cooperation of 'live and let live' which flourished between enemy soldiers in the First World War (Axelrod 1984). This might be accounted for in various ways. It may have arisen as the result of a soldier shooting — out of distraction, boredom, or nervousness -— at some clearly non-human target in the opposite trench. Or it may be that soldiers on both sides stopped shooting at regular intervals because they happened to have their meals at the same hours of the day. Such random signals may eventually have been 'interpreted' by one side as an inclination on the other towards an implicit truce, and they may have responded with other signals; first just to test for possible misunderstandings, then with increasing conviction, until the exchange slowly assumed the features of a stable cooperative abstention from mutual injury.

Diego Gambetta, Trust - Making and Breaking…, loc. 2789

Cooperation itself builds trust through demonstrated mutual restraint. [causal]

The probability that the other party will not act ina harmful way is raised by the understanding that mutual interest makes defection costly enough to be deterred. The soldiers' belief that they can trust each other results from an inference concerning the effectiveness of their interests as a motive for rational action in initiating and maintaining cooperation. Thus p is raised in the ' course of cooperation itself, without any assumption being made as to prior levels: 'The cooperative exchanges of mutual restraint actually changed the nature of the interaction. They tended to make the two sides care about each other's welfare' (Axelrod 1984: 85).

Promises are upheld through mutual perceived self-interest and shared convention. [causal]

Hume made the case for this process absolutely clear: When each individual perceives the same sense of interest in all his fellows, he immediately performs his part of any contract, as being assur'd that they will not be wanting in theirs. All of them, by concert enter into a scheme of actions, calculated for common benefit, and agree to be true to their words; nor is there anything requisite to form this concert or connection, but that every one have a sense of interest in the faithful fulfilling of engagements, and express that sense to other members of the society. This immediately causes that interest to operate upon them and interest is the first obligation to the performance of promises.

One defection need not justify prolonged retaliation against cooperative partners. [causal]

It would be best to have no memory,!® to forget that past defections may be repeated in subsequent moves. But in the case of individuals who do have some (finite) amount of memory, this is to prescribe as rational the avoidance of unconditional distrust even after the evidence would suggest it to be advisable. One inflicted 'wound', in this argument, should not be considered a sufficient reason for prolonged retaliation once the other side has been tamed by the first retaliatory response. Some degree of revealed preference for defection, in short, does not mean the absence of an interest in cooperation.

Tit-for-tat equilibrium requires mutual belief in its adoption. [causal]

Thus tit for tat can be an equilibrium only if both players believe the other will abide by it, otherwise other equilibria are just as possible and selfconfirming. To show that trust is really not at stake, Axelrod should have shown that whatever the initial move and the succession of further moves, the game tends to converge on tit for tat. What he does do is express a powerful set of reasons why —- under certain conditions and even in the absence of trust generated by friendship, say, or religious identity — a basic predisposition to trust can be perceived and adopted as a rational pursuit even by moderately forward-looking egoists. We learn that, tentatively and conditionally, we can trust trust and distrust distrust, that it can be rewarding to behave as if we trusted even in unpromising situations.

Cooperation can often substitute for costly interpersonal trust. [definitional]

The strategy of economizing on trust does not of course imply that we should wait for cooperation to evolve by itself; it just claims that we should set our sights on cooperation rather than trust. We should, in other words, promote the right conditions for cooperation, relying above all on constraint and interest, without assuming that the prior level of trust will eventually be high enough to bring about cooperation on its own account. … However, attractive as this strategy may be, it begs the crucial question of what is to be done either when p is so low that conditions suitable for cooperation are not available in the first place, or when p is not high enough to sustain potentially beneficial cooperation where those conditions are too complex, costly, or unpleasant to be a conceivable alternative to trust.

Trust is deliberately cultivated, not merely a by-product. [contrarian]

Conceptual and theoretical arguments likewise suggest that the maintenance of trust via the extension of associations based on personal bonds might be seen to involve an element of rational pursuit. Trust, although a potential spin-off of familiarity, friendship, and moral values, must not be confused with them, for it has quite different properties (Luhmann, this volume). It is perhaps such confusion which has led to the conclusion that we should treat it as both an eminently scarce resource and purely a by-product. This does not take adequate account of our ability to act, to simulate, try out, learn, apply and codify signals and practices which may initially be predicated on unintentional states, but which could be duplicated in the as if behaviour form far beyond their source.

Distrust is self-fulfilling and resists invalidation through experience [causal]

Trust is a peculiar belief predicated not on evidence but on the lack of contrary evidence — a feature that (as Pagden (this volume) shows) makes it vulnerable to deliberate destruction.

It then becomes individually 'rational' to behave accordingly, even for those previously prepared to act on more optimistic expectations) Only accident or a third party may set up the right kind of 'experiment' to prove distrust unfounded (and even so, as Good argues in this volume, cognitive inertia may prevent people from changing their beliefs).

Granting trust can actually produce the trustworthy behaviour it presupposes. [causal]

The concession of trust, that is, can generate the very behaviour which might logically seem to be its precondition. … Secondly, if behaviour spreads through learning and imitation, then sustained distrust can only lead to further distrust.
