Hey guys, answer me this question please. So research has found a positive correlation between brain volume and IQ. This seems pretty obvious. The thing is, with this in mind how can we account the sheer number of petite asian grills at my relatively prestigious uni? I swear some of these girls' heads are no bigger than a large grapefruit. Something just doesn't add up. Either their brains are just way more efficient/compact than the rest (thus able to process information well despite low cranial volume) or else there is some sort of trade-off occurring. For example, we might see hampered emotional and social intelligence as a result of more room for computation. If any neuroscientists could weigh in that would be amazing.
