The Third-Person Effect in Advertising: A Meta-Analysis

Abstract

Prior meta-analyses have found evidence for differences in the third-person effect across message types, indicating that the third-person effect is a communication context-specific phenomenon. These meta-analyses do not explain why effects of the perceptual hypothesis in advertising are smaller when compared to communication in general; they do not address the broad range of consumer behavior variables that are affected by third-person perceptions; and they have not investigated whether the perceived effects on the self or on others are better predictors for behavioral responses than third-person perceptions in advertising. This meta-analysis addresses these issues and investigates the perceptual and behavioral hypotheses of the third-person effect in an advertising context. Findings indicate that third-person perceptions in product advertising are weaker when compared to other communication messages due to developments over time and the mixed gratifications provided by product advertising messages. Third-person perceptions in advertising can increase or decrease consumer behavior depending on whether the behavior is self related (e.g., body-related responses) or other related (e.g., support for regulation). Furthermore, perceived effects on self or on others are better behavioral predictors than third-person perceptions, providing managerial implications for advertising campaign pretesting.
