Errors about errors: Virtues theory and trait attribution

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 form situationism.
