Does a bigger brain = smarter person?
I've seen so many things like "AHHH HOW DARE YOU SEXIST" when someone says men's brains are bigger than womens hence men are smarter than women, but is it actually the case?

It's more about grey matter density than volume per se, but men have greater grey matter density, too...

So it turns out that in general men are smarter than women? Then what happened in the IQ tests? Didn't it say that ON THE MEAN VALUE, women are as smart as men, but they deviate from the mean less, meaning there are more smart guys than smart women, but more dumb guys than dumb women?

I don't see how testosterone would increase someone's smarts.

Indians have the smallest brains in the world and they had some pretty high math history, so no brain size doesn't correlated intelligence even the Chinese scientists stated this.https://www.scmp.com/news/china/article/2054126/why-do-asians-have-bigger-brains-europeans-or-africans

Indians also have small and thin skeletons, so maybe that's why their brain need less nrg => smaller size to operate. Just making a speculation, don't bite me.

So do other non-West African Blacks and Negritos, do Abroriginals also have similar skeletons cause they look very fit when they're not fat.

It doesn't really. Men of average testosterone levels tend to be the smartest.

No, more neuron bodies (soma) does. Somas in the brain are located in the grey matter as said by >>13785364. His claim has no source though.
Bigger brain means high risk of brain or nerve impingement; which is very bad.

Fat tails are one of the hardest distribution characteristic to prove because you need a gigantic sample size to accept the hypothesis at a high significance level.

So we will probably never know for sure, but it would seem to fit what we see in real life (i.e. men having far more often extreme life outcomes than women).

I have a cranial circumference of 60 cm, 3.4 standard deviations above the mean. At age 16 I was administered the WISC-IV by a licensed psychologist and scored 151 (>99.9th percentile) on the General Abilities index. This is just an anecdote of course.

/sci/ will seethe at this but there's a bit of evidence from tranner studies that size isn't everything.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6235900/

>Table 2
>Hulshoff Pol et al
>Four months of anti-androgen and estrogen GAHT in MTFs decreased hypothalamic and total brain volumes and increased ventricle volume “toward female proportions” compared with MCs over one year.
>Four months of androgen GAHT in FTMs increased total brain and hypothalamic volumes and decreased ventricle volume “toward male proportions” compared with FCs over one year.

>Table 4
>Slabbekoorn et al
>No hormonal influence was found in either MTFs and FTMs on any of the following cognitive functions: verbal fluency, form recognition, fine motor mvmt, perceptual speed, hidden figures, verbal reasoning/general intelligence.

Parity was maintained vis a vis most cognitive functions despite estrogen shrinking MTF brains and testosterone enlarging FTM brains.
..but it should be noted that this study is a bit weird, since it found no difference in verbal fluency whereas most did. Quoting the meta-analysis:
>Administration of androgens to FTMs over 3 months was strongly associated with an increase in aggression, sexual arousal, and spatial ability, as well as a decrease in verbal fluency. Conversely, androgen deprivation in MTFs was linked to a decrease in anger and aggression, sexual arousal, and spatial ability, as well as an increase in verbal fluency.
so it could just be an outlier.

What's that? Other studies that examined general intelligence and non-gendered brain functions? That's the only one here. Haha. Ha.

I mean, you can have the biggest brain in the world relative to your size, but if you don't put it to good use then it just sits there consuming energy.

Animals with larger brains relative to size tend to be smarter, just as your brain density increases the more you exercise it.

But having a larger brain, just has having a greater muscular capacity generally may mean you have more POTENTIAL which is certainly true with men vs women. But it's really a double edged sword. As an anon said earlier. Men make up the smartest but they also make up the DUMBEST among us.

Not in school, it seems, where they are outperformed by women.
