Our moral sense really evolved to bind groups together into teams that can cooperate in order to compete with other teams.

Let me say it diplomatically: Most religions are tribal to some degree.

Groups create supernatural beings not to explain the universe but to order their societies.

Individuals who could not form cooperative alliances, on average, died sooner and left fewer children. And so we are the descendants of the successful cooperators.

If you have a personality predisposed to liberalism, you might gravitate more to the artsy crowd or the anti-establishment crowd. And then those peers will affect you, and they will give you values, and you will copy them.

If you grow up in a WEIRD society, you become so well educated in the ethic of autonomy that you can detect oppression and inequality even where the apparent victims see nothing wrong.

If you think that moral reasoning is something we do to figure out the truth, you’ll be constantly frustrated by how foolish, biased, and illogical people become when they disagree with you.
