Self-Sacrifice Among Strangers Has More to Do with Nurture than Nature
Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to those who contribute to food banks. This is the...
