This study proposes the third-person perception (TPP) can be viewed as a type of comparative social judgment in the domain of media influence, in that it is a function of assimilation, contrast, and anchoring mechanisms in the process of social comparison. The derived hypotheses were tested with web-based experimental data (N = 511). Results showed some evidence that TPP was a function of assimilation and contrast effects. There was also evidence that there were anchoring effects, and such effects tended to emerge when self was the anchor. Implication and directions for future research on TPP were discussed.
