根据2023年1月发表的一篇学术文章综述（见下），西方的民主选举，特别是美国的选举，近年来越来越注重竞选人的性格特征(personality traits）而不是竞选人宣传的政策（policies)。同时，选民自己的性格特征对其投票也有直接的影响。

总结起来就是：选人不选政策，已渐渐成为一种趋势。

注意，这个趋势与所谓的“选人不选党”，还是有一定区别的。竞选人往往都把自己的政策吹得天花乱坠，竞选成功后，是否实行诺言、能否实现诺言，很多政客并不在意，只要现在能抓住选票就好。选民们在一次次“上当”就后，就转而重视竞选人的性格特征了。

这样一个“选人不选政策”的趋势很有意思，是否在中间选民中大行其道，值得观察。也许两个月后的美国大选就能给出一个答案。

Democracies have become more individualized and party leaders are now the decisive actors in the political system. Data obtained presents consequences for the personalization of politics on democratic functioning. Voters' evaluation of candidates’ traits represents significant determinants of the vote. In the same vein, voters' traits are a major factor in voting outcomes. Through this review, we looked at the impact that personality traits of both voters and candidates can have on voting and how the personalization framework may help understand this increasingly present trend in Western politics. A thorough overview of the personality traits that influence voting behavior was provided. We add to the theory of personality trait matching and build a link between traits and the personalization of politics phenomena.
