Mentioned that too, but this was hand-waved as anecdotal.

cranial capacity correlates more strongly with hippocampal function than what we would recognize as intelligence

here's a couple Dunbar (yeah, that guy) papers: http://rsbl.royalsocietypublishing.org/content/roybiolett/early/2011/07/12/rsbl.2011.0570.full.pdf … http://www.uvm.edu/pdodds/files/papers/others/1993/dunbar1993a.pdf …

overall my impression is: 1. we don't have a reason to believe cranial capacity correlates strongly with IQ

2. sensory processing seems to require more volume than g or be more sensitive to volume available

3. If anything, if you extrapolate from data available for moderns, cranial capacity correlates inversely with IQ, but…environment.

So why is human child-birth torture, realistically? Gnon is evidently willing to rack women hard to squeeze-out bigger heads.

Neonate skulls are very soft and pliable though. And female human hips are larger to accommodate. All kinds of hacky workarounds.

Sure. But so long as the kid survives the process (and perhaps the mother too so she can have more later), then nature's done it's job.
