Evidence Quote

we going to find any IQ gland there's nowhere in the brain where if you hit it you eliminate fluid intelligence I just think that you know it'll turn out that you know this doesn't exist because what your brain is doing is a lot of learning individual specialized problems and then once those individual problems are learned then they get recombined for fluid
