My Book Review: The Righteous Mind refers.
As they say of their theory (edited), Recent research suggests that the function of morality is to promote cooperation: humans face, and have faced, a range of different nonzero-sum problems of cooperation, and have evolved and invented a range of solutions to them. These cooperative solutions take a variety of forms, including character traits, strategies, dispositions, behaviours, rules, norms, institutions, and technologies. Together, they motivate cooperative behaviour and provide the criteria by which we judge the behaviour, attitudes, and traits of ourselves and others. And it is this collection of cooperative solutions that philosophers and others have called morality. Because there are many types of cooperation, there will be many types of moral values. There are seven distinct types of cooperation: (1) the allocation of resources to kin; (2) coordination to mutual advantage; (3) social exchange; and conflict resolution through contests featuring (4) hawkish displays of dominance and (5) dovish displays of deference; (6) division of disputed resources; and (7) recognition of prior possession. And each of these types of cooperation gives rise to a corresponding type of morality: (1) family values, (2) group loyalty, (3) reciprocity, (4) heroism, (5) deference, (6) fairness, and (7) property rights.
This seems like a useful way of thinking of things; it makes morality a part of, and part conditioned by, what-makes-society-work; and since things need to be Darwinistically defensible, that fits. It also helpfully predicts that we will be less moral to strangers, other cultures, or people we perceive will be unlikely to cooperate with us.

by Henry Hazlitt, 1964.

* ACX has a post on Covid origins, which ends with general musing: "although the X theory is inherently plausible and didn’t start as pseudoscience, it gradually accreted a community around it with bad epistemic norms. Once X became A Thing - after people became obsessed with getting one over on the experts - they developed dozens of further arguments which ranged from flawed to completely false..." which seems nicely applicable to GW.
