if intelligence derives at least partly from genes, which I think it does, then yeah. Leary with his Eight Circuits model, Ken Wilber and his integral theory and the theory of Spiral Dynamics (which Wilber did not invent, but has adopted) (I urge you to look into it) have talked about more literal and simplistic levels of belief and higher levels of belief. intelligence could act in part as a sorting mechanism to see what level of belief a person eventually adopts. (you can’t adopt a belief if you can’t understand it, for starters.)
