Sexist title, unconvincing article, but the last two paragraphs are very good and made something click for me: The authors of the study suggest that the reluctance might be the result of a psychological development that makes us averse to any kind of extreme behavior, either selfish or selfless, even if the rules are set up to reward the extreme. This may be advantageous in the sense that extreme strategies could be costly if we misunderstood the rules, or if the rules change without warning. The authors even suggest that our brains may intentionally fire some kind of calculation error in extreme situations to prevent hazardous "all-in" commitments.
