I think there’s a clear correlation there, but the axes are reversed: testosterone can’t be the dependent variable of IQ score. Reversing the axes makes the gradient look incredibly steep, but that’s only because of the obviously incorrect anomaly. r=0.435 is very much not a strong correlation, but it’s not zero either, especially with a sample size this enormous.
If you remove the anomaly, which may be due to an accidental additional digit, that correlation coefficient may climb a bit.
IMHO, they plotted an independent variable over random noise. The one gigathad changes nothing.

no, IQ can actually drive testosterone levels! it’s a strange feedback loop where social pleasure can cause testosterone production.
