"Actual criminals—the very people Gad Saad thinks possess no empathy—betray each other far less often than the regular population. So much for “no honor among thieves.”

Reading the premise of the prisoner's dilemma again I'm also struck by the fact that it's just a made up thought experiment. Real criminals, I suspect, understand quite well that a major reason cops are trying to get you to rat someone else out is because they don't have any real evidence on you. So in real life if no-one speaks there's a good chance that everyone goes free.

Nash equilibrium - at least in the form of the prisoners dilemma - is a great example of an elegant theory that produced a lot of real-world behaviour that all completely forgot that the theory itself is built on assumptions that were put in place not necessarily because they resemble reality but rather because they provide a useful illustration of the subsequent explanation. The entirety of classical economics seems to be like this. "If we assume man is rational and self-interested then X,Y and Z must be true". Yeah, great for you but the central premise isn't true.

For sure, if I assume that Scarlett Johansson is wildly attracted to me then it makes complete sense to try and engineer an opportunity to get her alone. I'm reality, though, what's much more likely to happen there is me getting arrested or beaten up by her security detail. I can theorise literally anything if I make the right kinds of assumptions and don't test those on reality itself.

Also, I’m not sure I buy the distinction between social determinants and “well that’s just the way some people are.” Suppose some has a fundamentally different way of view the world, and that view is somehow hardwired, whether by genes or the uterine environment or whatever. Empathy is only all the more important, if only for practical reasons. Like, you have to be able to inhabit their worldview to predict how they might act, feel what they feel, if only as a tourist.
