Inclusion of theory-relevant moderators yield the same conclusions as Sedikides, Gaertner, and Vevea (2005): A meta-analytical reply to Heine, Kitayama, and Hamamura (2007)

Abstract

Heine, Kitayama and Hamamura (2007) attributed the Sedikides, Gaertner and Vevea (2005) findings to the exclusion of six papers. We report a meta-analysis that includes those six papers. The Heine et al. conclusions are faulty, because of a misspecified meta-analysis that failed to consider two moderators central to the theory. First, some of their effect sizes originated from studies that did not empirically validate comparison dimensions. Inclusion of this moderator evidences pancultural self-enhancement: Westerners enhance more strongly on individualistic dimensions, Easterners on collectivistic dimensions. Second, some of their effect sizes were irrelevant to whether enhancement is correlated with dimension importance. Inclusion of this moderator evidences pancultural self-enhancement: Both Westerners and Easterners enhance on personally important dimensions. The Sedikides et al. conclusions are valid: Tactical self-enhancement is pancultural. © 2007 Blackwell Publishing Ltd with the Asian Association of Social Psychology and the Japanese Group Dynamics Association.
