No they’re not. People clearly play the Iterated Prisoners Dilemma even in contexts where they’ve been intentionally isolated and freed from context (eg, psychology experiments) because we’ve evolved a group mentality — one that encodes game theory optima as a primal impulse. Corporate leaders who forget that tend to blow their own company up, when humans instinctually repay defection with defection — as cold, hard math dictates they should. We’ve seen many examples, in different context - from pay withholding to marketing campaigns that denigrate customers. Fighting human nature is stupidity.
