Studies disagree as to whether an optimistic bias can account for the commonly observed third-person perceptions. This study aims to help clarify the relationship between third-person perceptions and biased optimism in the context of assessing the impact of the news about bird flu outbreaks in Taiwan. Using a random sample of 1,107 college students, third-person perception and optimistic bias were found to be robust but unrelated. Although both optimistic bias and third-person effect are psychological perceptual judgments that can be attributed to self-serving motivation, the third-person perception is a biased interpretation of media influence, while biased optimistic perceptions are a social psychological mechanism of bolstering self-esteem in self-other comparisons regarding a risk.
