- A Constant Error, Revisited: A New Explanation of the Halo Effect Chris Westbury Daniel King Cognitive Science AbstractJudgments of character traits tend to be overcorrelated, a bias known as the halo effect. We conducted two studies to test an explanation of the effect based on shared lexical context and connotation. Study 1 tested whether the context similarity of trait names could explain 39 participants’ ratings of the probability that two traits would co‐occur. Over 126 trait pairs, cosine similarity between the word2vec vectors of the two words was a reliable predictor of the human judgments of trait co‐occurrence probability (cross‐validated r2 = .19, p < .001). Two measures related to word similarity increased the variation accounted for in the human judgments to 45%, cross‐validated (p < .001). In Experiment 2, 40 different participants judged similarity of word meaning within the pairs, confirming that the word pairs were not simply synonymous (Average [SD] = 40.8/100 [13.1/100]). Shared lexical context and word connotation play a role in shaping the halo effect. 10.1111/cogs.70022 http://creativecommons.org/licenses/by-nc-nd/4.0/
