So, because women have a much lower content of Testosterone, we can conclude that there are much more stupid than men or what does this silly correlation wants to tell us???
The only thing this graph shows is that average people are average. This graph essentially shows no -> very weak correlation between testosterone levels and IQ. in fact I would say this graph argues that correlating testosterone levels with IQ is essentially flawed. However because of the way the data is represented it makes it look as though there might be a correlation.
AFAIR the R2 is (almost) equal to rho in the Pearson correlation. I just see two variables, a linear fit from - possibly - an OLS. The small R2 is likely due to the outlier (though a single outlier by this mass of points raises my eyebrows as the MSE (or take the RSME) won’t be affected as such by a single point when there are 15’000 points centered closely around an estimate, but CCV would tell) and R2 says nothing about the p-value, which is determined by the amount of information in a system/about variables, and hence likely way below 0.05.
This relationship aka in this case correlation says pretty much nothing about real world, because IQ is (possibly) not only determined by IQ, but way many other factors. The picture is utterly simplified. It is similar to the relationship between the number of babies and the number of storks.
His takeaway is that women are as smart as men (as in the IQ is the same) but because men have higher testosterone holding them back men are actually smarter than women. What I think he’s actually trying to say is that he’s a high testosterone misogynist.
this graph very clearly states it’s only related to men and has nothing to do with women at all. the only thing it shows is that the majority of men have average intelligence and average testosterone levels. R2=0.19 value means only 19% of the variation in testosterone levels can be explained by IQ, leaving 81% unexplained. This is a very weak relationship, bordering on statistical noise.
The thing about very superficial analysis like this is you can just go fishing for correlations and come back with something meaningless but publishable.

This poster is High T. Ask me how I can tell.
Understand the meaning of question marks, you do not? Much to learn, little Padawan, you still have.

It’s about men but your takeaway would be that women are smarter because as IQ goes up, Testosterone goes down
Absolutely right. Sorry.

Your conclusion is based on deduction which in many occasions - like this one - leads to false conclusions. Try again.
Wait? So the other person isn’t being misogynistic? I’m lost.
If that is someones takeaway they are wrong. This chart essentially shows that these things are not actually correlated.

I wonder why they chose IQ as the independent variable? Surely it would be the other way around.
