This paper examines the implications of certain social psychological experiments for moral theory—specifically, for virtue theory. Gilbert Harman and John Doris have recently argued that the empirical evidence offered by ‘situationism’ demonstrates that there is no such thing as a character trait. I dispute this conclusion. My discussion focuses on the proper interpretation of the experimental data—the data themselves I grant for the sake of argument. I develop three criticisms of the anti-trait position. Of these, the central criticism concerns three (...) respects in which the experimental situations employed to test someone's character trait are inadequate to the task. First, they do not take account of the subject's own construal of the situation. Second, they include behaviour that is only marginally relevant to the trait in question. Third, they disregard the normative character of the responses in which virtue theory is interested. Given these inadequacies in situationism's operationalized conception of a ‘character trait’, I argue that situationism does not really address the proposition that people have ‘character traits’, properly understood. A fortiori, the social psychological evidence does not refute that proposition. I also adduce some limited experimental evidence in favour of character traits and distil two lessons we can nevertheless learn from situationism. (shrink)

Ordinary moral thought often commits what social psychologists call 'the fundamental attribution error '. This is the error of ignoring situational factors and overconfidently assuming that distinctive behaviour or patterns of behaviour are due to an agent's distinctive character traits. In fact, there is no evidence that people have character traits in the relevant sense. Since attribution of character traits leads to much evil, we should try to educate ourselves and others to stop doing it.
