Distrust forces people to act from crippled knowledge. [causal]
It follows that I will have to make choices with less information to go on than other, more optimistic people have. Although there might be specific instances in which information is deleterious to my well-being, it is generally beneficial to have more information about one's circumstances. It is not an intention, but merely an effect, of distrust that it can put one at a relative disadvantage on this score. Hence in a society with pockets of distrust, such as in hostile ghettos or in the cases of individuals with particularly bad experience of misplaced or undeveloped trust, some people will have to act from crippled knowledge.
