imho, you're wrong: it may not be "human nature" as much as it is prisoner's dilemma. few, but some, humans are just as inherently averse to corruption as someone may be inherently prone to it. it's a matter of "if I don't take this bribe, someone else will"

That is still human nature. Not everyone will exhibit those traits, but when looking at the entirety of humanity, these traits are certainly part of our nature.

And the prisoner's dilemma is a way of exploring/explaining these traits (though I expect these aren't exclusive to humans).

hmm. I suppose a sentient ant may not reach a Nash equilibrium, but the best equilibrium. Then through that lens, yeah. I can see how you see it as human nature.
