Distinctiveness of others, mutability of selves: Their impact on self-evaluations.

The authors postulate that the outcome of social comparison processes is determined by the role social comparison information serves during the self-evaluation process. Assimilation is more likely in situations that instigate the inclusion of social comparison information in self-representations. Contrast is the more probable outcome when information about another person is used as a reference point for self-judgments. Whether comparison information instigates interpretation or comparison effects depends on the distinctness of this information as well as the perceived mutability of the self. The authors found support for their perspective using different types of manipulations of the distinctness construct, treating self-mutability as a contextual as well as an individual-difference variable, and measuring the effects of social comparisons on measures likely to reveal both assimilation and contrast effects (self-evaluative judgments and behavioral predictions), assimilation effects only (mood measures), and motivational self-repair effects (importance ratings of the focal comparison dimension).
