The political psychologists Hatemi, Crabtree and Smith accuse orthodox moral foundations theory of predicting what is already intrinsic to the theory, namely that moral beliefs influence political decision-making. The authors argue that, first, political psychology must start from a position which treats political and moral beliefs as equals so as to avoid self-justificatory theorising, and second, that such an analysis provides stronger evidence for political attitudes predicting moral attitudes than vice versa. I take this empirical result as a starting point (...) to intervene in a debate in contemporary normative political theory which has, to my mind, become largely unwieldy: the political realism controversy. I advise the realists to ‘downplay’ the (thus far) inconclusive debate over realism’s metanormative standing in favour of a non-metanormative inquiry. Hatemi, Crabtree and Smith’s study makes for an excellent backdrop. It affirms the realist hypothesis that politics is in some relevant sense – a causal, psychological sense – prior to morality.
