We’re born with tunable and extendable social-rule processors, just like our language-rule processors.
As Jag Bhalla points out in today's lesson, saying “morality… doesn’t have much to do with the physical world” can mislead. Its relationship is like that of math or logic. And an evolutionary social-rule math and logic applies: social-species groups with more productive social-rules do better.
Conversely, nature tends to eliminate those whose rules allow damage to what they depend. The math and logic of teams sometimes (perhaps often) opposes maximizing self-benefit. We’d all benefit if that idea was widely shared.
