Overview

A short excerpt from Frans de Waal's TED talk showing a capuchin monkey fairness experiment in which two monkeys are paid unequally, one with cucumber and one with grapes. The shortchanged monkey reacts angrily.

HN uses it again and again as shorthand for the idea that resentment of unfair pay and inequality is built into primates, including us.

This is the video that explains the best how the "morality" is natural even in the capuchin monkeys: [VIDEO] So, no to those that claim that, humans aren't special, and no, the good sides of morality don't come from religion, especially not from the modern ones with a "jealous" god (killing homosexuals, or punishing women when not wearsing something, however, if that is considered "morality", indeed provably does come from religion). The whole talk: [LINK]

There's a nice video from a psychological experiment that illustrates it: [VIDEO] I think evolution hardwired our primate brains against inequality. We go out of our way to punish those who don't play nice and share with the broader group. Otherwise complex societies would have never emerged, because assholes exploiting and taking advantage of peers would ruin and doom any group larger than a few individuals.

This experiment, listed in one table and in the references but not discussed elsewhere, would suggest otherwise: [VIDEO] There might be other confounding factors in that experiment, but for the life of me I can't imagine what they would be. My stats knowledge has evaporated over the years so I can't follow exactly what the study is doing to come to their conclusion, but it strains my credulity to suggest that the monkeys in that experiment aren't angry about perceived inequity. I'd be interested to know if anyone can do a TLDR of the study as to why they reached that conclusion in the face of what looks like pretty compelling evidence. Edit: Now I come to think about it, I suppose a counter-argument is that the angry monkey just knows that the experimenter has grapes and they're angry they're not getting them, rather than being angry that the other monkey is getting grapes while they're not. Feels like that argument makes sense given our tendency to anthropomorphise animals, particularly primates.
