I don’t buy it. Lots of species have predators and have had them for a long time, but very few species have intelligence. It seems more likely that most of our intelligence is due to sexual selection, a Fisherian runaway that accidentally focused on intelligence instead of brightly colored tails or something.
The post describes how predation creates a specific gradient favoring better modeling of predator behavior. While fact that most predated species don’t develop high intelligence is Bayesian evidence against this explanation, it’s very weak counterevidence because general self-aware intelligence is a very narrow target. More importantly, why would sexual selection specifically target intelligence rather than any other trait?
Looking at peacocks, we can see what appears to be an initial predation-driven selection for looking like they had big intimidating eyes on their backs (similar to butterflies), followed by sexual selection amplifying along roughly that same gradient direction.
Your theory would predict that we’d be much better at modeling tigers (which hunted us) than at modeling antelopes (which we hunted), but in reality we’re about equally bad at modeling either, and much better at modeling other humans.
This seems mostly right, but, seems plausible to me that the predatory/prey cycle was a necessary prerequisite to get us into a basin where intelligence-sexual-selection was a plausible outcome.
