Yes I remember Klinefelter syndrome from general psych 2. It is a fairly rare chromosomal syndrome. We learned about it the same unit we learned about Down syndrome and other chromosomal syndromes .
@firemonkey you would like general psych 1 & 2. Ever thought of taking an online class?? Even if it were free on coursera I bet you’d love it 
I started a couple at https://www.futurelearn.com/ , but didn’t have the mental stamina to stick with them till the end of the course.
This is why I get annoyed when people ask me if I’m “biologically” a man or woman, or say there are only two sexes. The truth is, unless you’ve had a genetic test done, nobody knows for sure, and plenty of folks fall somewhere in the middle.
A snippet of research about Klinefelter and schizophrenia.
That’s interesting, but with a sample size of 32 it’s not very representative.
I think I’m biologically a man . I have to shave regularly but…?! @Ninjastar you’re right it’s not certain minus a genetic test.
You’re right about the sample size . I found this https://onlinelibrary.wiley.com/doi/abs/10.1002/ajmg.b.30163 but it’s an even smaller sample size.
Here’s another genetic anomoly where women grow up believing they are entirely physically female, but when they can’t have kids, a genetic test discovers that they have XY chromosomes and just did not respond typically to hormones in the womb.
A lot of things are on a spectrum I think. I may be only 1% female and 99% male. But I believe it is on a spectrum.
My height comes to mind. My mom is about the same height as me while my dad is 3-4 inches taller than me. It’s possible I got female genes when it comes to my height. It’s possible idk. Maybe there’s a few other things. Maybe I can’t produce children. I’m not sure yet. But maybe maybe maybe.
We need more open research without biased studies. But I always love it when a study is designed to figure out one biased POV and then the researcher turns around and says it’s the complete opposite in reality according to his/her/their results 
I used to love when this would happen to me on research projects in school. Like one time, back when I was much more cynical, I was studying economics and comparing companies who have high employee retention and satisfaction rates to companies with high turnover and low satisfaction, and found that although the companies with high turnover made higher profits, they were much more unstable and the graph of profit had a lot of peaks and valleys, whereas the companies with high retention had a slightly lower but incredibly predictable and steady rate of growth and profit.
At the time I had been trying to prove that the system punishes companies who treat employees well, and we need more laws in place to prevent abuses. Instead, I discovered that the opposite is true, and I had to revamp my entire thesis.
It seems You’ve done it all @Ninjastar !!
I’m impressed truly am
It was just a core elective. I would never study economics by choice
