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: ▶ this 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: ▶ this 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: ▶ this 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.

I think you're right, but historically there have been problems. Frans de Waal has written about how in his field there was a lot of early egregious anthropomorphizing. As people realized how flawed that was, they swung around the other way, to refusing to consider analogous human behavior. But things like de Waal's work demonstrating moral sense in animals is hard to explain in any other way. [1] Even so, it can be tricky. In Bernd Heinrich's excellent "Mind of the Raven" [2], he points to a story where a woman, lost in the wilderness, noticed a raven crying near her and spotted something like a mountain lion creeping up on her. In the news story she gave the raven credit for warning her and saving her life. But Heinrich points out that ravens have a demonstrated history of leading predators to prey, because that way they get the leftovers with much lower risk. So although the woman was correct that the raven understood her danger and was demonstrating advanced social cooperation, her anthropomorphic bias led her to perhaps be dangerously wrong about who the raven was trying to help. So although I think shorthand like, "The octopus is playing" is fine for casual use, I think serious people have to always be challenging those tempting assumptions.

This is how we're wired as a species, and frankly more than just a species. We don't just look at what we have and what we want, we look at what other people have and ask ourselves why they got it and we didn't. At a basic level it's an instinct that exists in lower primates, and in us as well. ▶ this video The difference with us is that we can learn and understand the reasons why one person gets a "grape" and the other a "cucumber"... and those answers are often not just unsatisfying, but infuriating.
