Abstract: | The tendency for individuals to perceive a greater impact ofmedia messages on others than on the self, Davison (1983) argues,has led to a number of policy decisions in which éliteshave exercised control of mass media messages in order to protectvulnerable others. The third-person effect has been well-documentedin experimental research with little attention to its theoreticalunderpinnings, or its antecedents or consequences. This articleargues that the third-person effect can be understood throughattribution theory, especially through the concepts of self-servingbias and effectance motivation. Second, it demonstrates thatthe third-person effect is influenced by certain social structuralfactors, media use patterns, and perceived harm of content.Finally, while perceptions of harm are related to perceptionsof influence, influence does not play a role in predicting supportfor external control of media content, while perceived harmhas a significant impact. |
