Experimental manipulation of the halo effect

Abstract

To test the hypothesis that halo effect is a judgmental error rather than the effect of objective correlation of traits, one group (N = 18) rated 5 noted individuals, one individual per day on all of 5 traits, while another group (N = 18) rated all 5 individuals on one trait per day. The authors state that the results prove that halo is in part a phenomenon of judgment. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
