Morality is an evolved sense of fairness, not a late intellectual achievement

Evidence

As Dunfield & Kuhlmeier summarize: “Taken together, recent research supports the idea that, under certain circumstances (e.g., instrumental need as opposed to material desire), early prosocial behaviours conform to the predictions of the presented mutualistic approach to morality.” … We see this early and universal pattern as strongly suggesting that true morality is not a sophisticated, late, and non-universal intellectual achievement (as Kohlberg 1981 implied) but is based rather on an evolved sense of fairness. — Nicolas Baumard, A mutualistic approach to morality, 656

• DEEPTHINKING: The claim that fairness is instinctive rather than developmental inverts centuries of moral-psychology assumptions and reframes what cross-cultural uniformity proves about human nature.
