Some recent work on the self-fulfilling prophecy appears to show that first impressions are immune to disconfirmation, even when contradictory information arises during face-to-face interaction. Analysis of data from a previous study (Bond, 1972), however, shows that such disconfirmations can occur, with the extent of impression change closely mapping the degree that the prior impression about the other person departs from consensual reality. The fundamental issue involved in this research, however, is not the psychologist's conclusion about confirmation and disconfirmation: the question is change in the subject's impression, its extent, and the conditions which promote such change during social interaction. Suggestions are offered for research within this framework.
