Close-knit communities substitute communal norms for dyadic trust [causal]
When we have the thick relationships of a small, close community, we may find that our interactions are governed by norms of cooperativeness that are collective rather than dyadic. I behave well toward you because the community will sanction me if I do not. In such a case, the norms of cooperativeness may be sufficiently effective that we do not so readily develop dyadic trust relationships over many things, because those things are governed by the communal norms (Cook and Hardin 2000).
