Check out the work by Simon Baron Cohen at Cambridge, which includes studies on newborns showing clear differences between genders. http://www.math.kth.se/matstat/gru/godis/sex.pdf

Also check out the work of John Money, who popularised the concept of 'gender as a social construct', and wrecked the life of a young man whose penis had been destroyed by trying to raise him as a girl: https://en.wikipedia.org/wiki/David_Reimer.

Yes, indeed.

If anyone ever fails us to understand how blind spots in our perception and cognition work, one of the best examples is to contrast the intensity of calls for equal treatment for the sexes with the fact that up to 80% by region of American baby boys [1] get a piece of their sexual organs removed shortly after birth.

Moreover, we even allow Mohels to suck the baby's penis clean and have a celebratory meal afterward, called a Seudat Mitzvah [2]. And the fact that babies sometimes contract herpes and die from it [3] doesn't stop it.

So that's a hell of a blind spot, although I won't say it's just academics with power, it's numerous institutions including the religious ones, the corporate ones and even outlaw institutions. The evil that happens to people is the accumulation of all the mundane evil people in institutions do to protect themselves.

(currently finishing Masters in Methodology/Statistics in Psychology) There is evidence of inter-sex differences (and in many areas girls are at advantage), but the provably innate part is small, and the intra-group variance coming from other factors (that may include elements of culture) is much bigger. This allows for conclusions on population, not individual level. On a related note, affirmative action programs seem to work to societies benefit.

Another comment that phrased it well: https://news.ycombinator.com/item?id=9845165

And absolutely regardless of John Money being misguided and vilified (I don't think I even heard of him before recent Catholic backlash), gender is a legitimate and in depth academic topic.

I just saw this. It worried me that you're apparently studying psychology but consider someone who abused a child to prove a theory to be 'vilified'.

Yes, I understand that the means may differ significantly but the variances are fairly large so there is lots of overlap between sexes, just as the article linked by OP discusses. Although, there are many characteristics and they all aren't going to exhibit the same spreads. I wonder if some have significantly smaller variances. The characteristic I keep noticing is how rough young boys are when they play compared to young girls. My small sample shows a very tight variance; young girls are much softer in their play compared to boys. Is that cultural conditioning at such a young age?
