The (iterated) prisoner's dilemma is a massively simplified but nevertheless (therefore?) interesting topic. It has captured our human imagination for decades, for better or for worse: https://www.wired.com/2004/10/new-tack-wins-prisoners-dilemma/ https://www.wired.com/2004/10/new-tack-wins-prisoners-dilemm... I say "for worse" because as with all oversimplified models (aka all models), there's always the risk that someone will take the results out of context and claim "But it's a fact! Science says so!". ...As they did with the original "tit-for-tat" IPD strategy, and as happens routinely with various "evolutionary justification for X" arguments.
