Evolutionary leadership theory and economic voting: Warmth and competence impressions mediate the effect of economic perceptions on vote
基于进化领导理论，研究了经济感知如何通过领导者的温暖和能力印象影响投票选择，使用了17次选举的调查数据和两个实验验证因果关系。
Leaders' persona and the state of the economy are among the two most salient topics during election campaigns. Existing scholarship treats these as two independent or even competing factors. Economic perceptions are overlooked as cues for leader evaluations, while leader evaluations rarely enter considerations of the economic vote. This article builds on evolutionary leadership theory to bridge these distant literatures. It proposes that evaluating leaders' performance based on the resources available to group members may have improved followers' fitness ancestrally. Accordingly, it predicts that the effect of economic perceptions on vote choice is mediated by leaders' warmth and competence impressions in modern democracies. To test these predictions, the article first analyzes representative survey data from seventeen elections in three countries (USA, Australia and Denmark). Second, it relies on two original, well-powered manipulation-of-process experiments to test the validity of the causal claims.
