The more intelligent a person, the fewer dendrites there are in their cerebral cortex


What he’s talking about here is learning, right? There are two things - learning, and inferring. When learning, the aspects you and Max mention are probably quite important (I don’t know, what do empirical results say?!). When inferring, you’re not learning, unless of course you get your inference wrong, then someone tells you the answer/their reasoning, and then you go “ahhh I see” and you learn.
