 These interpretations of the experiments in social psychology have been challenged by both psychologists and philosophers, especially by philosophers working in the tradition of virtue ethics (see related entry on  virtue ethics),  who claim that the character traits criticized by situationists have little to do with the conception of character associated with the ancient and modern moralists. The objectors say that the situationists rely on an understanding of character traits as isolated and often non-reflective dispositions to behave in stereotypical ways. They wrongly assume that traits can be determined from a single type of behavior stereotypically associated with that trait.
