Since I’m already ranting and possibly pissing off people, let me toss this out there: I think that there are differences between the sexes and races in things like intelligence. I’m almost certain of it. So please stop acting like it’s immoral to claim that such a thing is possible. However, the data and statistical modeling skills that you would need to uncover such a difference are substantial: you’d need to control for upbringing, culture, nutrition, age, and a million other things. And even if you got that all totally under control, you’d still have to account for the fact that your sample – even if it were the entire population of earth – is not truly the whole population of human beings.
Don’t believe me? Here are five simulations of intelligence scores (note: to get this empirically, you would have to have a perfect metric for intelligence). Back is male, red is female, n=10,000,000. All these simulations are randomly-generated normals – except that one sex has each score shifted to the right by a fairly significant amount, to account for its superiority. It’s the same sex shifted by the same amount in all five simulations. Sorry for the low-quality pics:
Can you tell which sex has the advantage? Me, either. And if you could, would it change the way you acted toward individuals of a particular sex? Me, either – they overlap so much that you would be foolish to assume that the person in question fell into the left- or right-most areas, where sex actually makes a difference. Either way, the person would probably be so stupid or brilliant that you wouldn’t really be wonder if somebody of the opposite sex might be just a bit dumber or smarter.
*I am praying to God (please forgive me for my years of agnosticism!) that no quantitative people read this and shred my simulation technique.
