Many people feel compelled to disassociate themselves from wrongdoing. We call judgments to the effect “disassociation intuitions.” Do disassociation intuitions have a common cause? Why do they seem so obvious and resistant to countervailing reasons? How did they become so widespread? Here, we argue that disassociation intuitions are a natural product of gene‐culture co‐evolution. We also consider the mechanism that gene‐culture co‐evolution employed to achieve this result, arguing that a plausible candidate is disgust and its cultural echoes. This theory of (...) disassociation intuitions suggests a promising research program in the philosophy of psychology, which provides new ways of thinking about higher cognitive emotions, and biologically constrained cognitive capacities generally.
