What’s the relationship between morals and politics? According to Moral Foundations Theory (MFT), people rely on multiple evolved intuitive “foundations” when making moral decisions, including: Care, Fairness, Loyalty, Authority, and Purity. A substantial body of previous research has found that, when making moral decisions, political liberals place more emphasis on Care and Fairness, whereas political conservatives place more emphasis on Loyalty, Authority, and Purity. However: the way that this research has conceptualised moral and politics has been criticised; there have been some anomalous and contradictory empirical findings; and it remains unclear whether the relationship between morals and politics is causal as opposed to merely correlational. Here I review the literature and make suggestions for future research.
