Why did men evolve bigger brains than women?

Why do they have it when women can be successful and have smaller brains? If you don't need to have it, doesn't it seem like a huge cost in the long run?

    to compensate for lower bandwidth between brainparts?

    Sure most geniuses happen to be male, but so are most actual retards. It's not that men are more intelligent than women on average, but more that the differences in intelligence are bigger among men than among women

    That’s why Einstein is a man.

    Proportionately, women have larger brains than men. The average man's brain has a mass of 1336 grammes, which is 11% larger than a woman's brain, but the volume of a man's body is on average 42% larger, so in fact women's brains are proportionately 27% larger than men's. So the real question is why aren't men's brains larger?

    One hypothesis

    partially supported by evidence

    is that intelligence can be predicted by comparing the ratio of brain mass to body mass.

    Consider, for example, the elephant, which has a huge brain compared to human beings (more than double the size).

    But...elephants aren't out-rocket-sciencing human rocket scientists.

    The elephant's brain mass to body mass ratio is lower than that of humans.

    So

    if we imagine this ratio thing is valid

    then one can see that the human male

    which typically has a larger body than the human female

    **in order to be equal in intelligence to the female**

    ought to have a brain that is (on average) larger than the human female's

    in the same ratio that the human male's body is (on average) larger than the human female's

    men are simply more intelligent, funnier, better at science/logic math etc

    • I'm not judging your view but that sounds like a symptom, not the underlying cause.
