I know of the hypothesis, but it doesn't address the problem that it's an unfalsifiable explanation.
It's observing an event, formulating an explanation for it that sounds plausible enough, but the explanation is unfalsifiable, and a number of other explanations that are just as plausible and unfalsifiable can be proffered.
I think you might be confusing a few different things. I originally wrote "Game theory predicts" because this has been worked out with some rigor in game theory. You should never assume that anything in game theory necessarily applies to real life. At best, game theory models give us a starting point for other lines of inquiry. That's the whole of the claim, not that this is real, but only that there is a game theory model where this works well.
