The uniquely human emotion of disgust is intimately connected to morality in many, perhaps all, cultures (Rozin, Lowery, Imada, & Haidt, 1999b). We report two studies suggesting that a predisposition to feel disgust (“disgust sensitivity”) is associated with more conservative political attitudes, especially for issues related to the moral dimension of purity. In the first study, we document a positive correlation between disgust sensitivity and self-reported conservatism in a broad sample of US adults. In Study 2 we show that while disgust sensitivity is associated with more conservative attitudes on a range of political issues, this relationship is strongest for purity-related issues—specifically, abortion and gay marriage.
