So there appear to be important individual differences in behavior among participants in these game environments. Since the situation a given group of participants is confronting is the same, it is only natural to think that the ensuing differences in behavior might be explained, at least in part, by differences in their underlying personality traits. If this turns out to be the case, then if we learn something about their personality, we could more accurately predict how they would subsequently behave in these games, as well as in other relevant situations. In other words, individual differences in the moral psychology of a person’s justice relevant traits, can translate into individual differences in justice relevant behavior. And knowing something about the former can help us predict the latter.
