ABSTRACT

A growing number of studies demonstrate that consistent handers, people who use their dominant hand for all or most manual tasks, are less cognitively flexible than inconsistent handers, people who use their non-dominant hands at least some of the time. A recent hypothesis suggests that differences in handedness emerged evolutionarily because populations benefited from a balance between cognitively rigid and cognitively flexible people. One expectation is that cognitively rigid consistent handers would support more authoritarian policies or candidates. To test this idea, we looked at handedness, gender, and political affiliation as predictors of support for Donald Trump, a candidate whose supporters self-report being more authoritarian, in the 2016 primary. Our data show that in the Republican Primary, consistent handers report more support than inconsistent for Donald Trump. When authoritarianism was added as a covariate, the handedness effect disappeared. Further analyses showed that authoritarianism mediates the relationship between handedness and support for Donald Trump. In the Democratic Primary, there was a main effect of gender. Women reported more support than men for Hillary Clinton.

摘要

越来越多的研究表明，一致不一致的处理者，即在所有或大多数手动任务中使用惯用惯性手的人，在认知上的灵活性不如不一致专家（至少在某些时候使用非惯性惯性的人）。最近的一个假说表明，由于人们受益于僵硬的人与灵活的人之间的平衡，因此习惯性差异在进化上出现了。一个期望是，在认知上僵化的一致处理者将支持更多的威权政策或候选人。为了检验这个想法，我们将惯用惯性，性别和政治背景视为支持唐纳德·特朗普（Donald Trump）的候选人，唐纳德·特朗普（Donald Trump）在2016年初选中其支持者的自我报告更加专制。我们的数据显示，在共和党初选中，一致的处理者表示，对唐纳德·特朗普的支持比对不一致的支持更多。当添加威权主义作为协变量时，惯用性效应消失了。进一步的分析表明，威权主义调解了权势与对唐纳德·特朗普的支持之间的关系。在民主初选中，性别产生了主要影响。对于希拉里·克林顿，女性支持率高于男性。
