根據2023年1月發表的一篇學術文章綜述（見下），西方的民主選舉，特別是美國的選舉，近年來越來越注重競選人的性格特徵(personality traits）而不是競選人宣傳的政策（policies)。同時，選民自己的性格特徵對其投票也有直接的影響。

總結起來就是：選人不選政策，已漸漸成為一種趨勢。

注意，這個趨勢與所謂的“選人不選黨”，還是有一定區別的。競選人往往都把自己的政策吹得天花亂墜，競選成功後，是否實行諾言、能否實現諾言，很多政客並不在意，只要現在能抓住選票就好。選民們在一次次“上當”就後，就轉而重視競選人的性格特徵了。

這樣一個“選人不選政策”的趨勢很有意思，是否在中間選民中大行其道，值得觀察。也許兩個月後的美國大選就能給出一個答案。

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.
