In case you're not familiar with the concept of "everest regression", coined by
@GarettJones, here's a short description I found.pic.twitter.com/gnwbwOX2wz

Another example of an Everest regression would be; "if you control for bone length, men aren't taller than women". It's a pretty common trick.

*Controlling for sex, testosterone doesn't influence athletic performance.

I doubt that one's true—I would guess that within-sex variation in testosterone influences performance, too. Visuospatial ability might be an interesting example (the "optimal" T level is above the female mean but below the male mean)

>Visuospatial ability might be an interesting example (the "optimal" T level is above the female mean but below the male mean) Definitely not - hitting a baseball is the purest visuospatial test in sports and it's massively enhanced by exogenous testosterone*

"Definitely not"—overconfident much?! That would be an interesting speculation in the absence of better data, but people actually study this stuff! My source is Arthur Jensen, The g Factor, Ch. 13., who cites https://www.sciencedirect.com/science/article/pii/1041608095900055 … and https://www.sciencedirect.com/science/article/pii/1041608095900039 …pic.twitter.com/913YNOQ2LZ

Yes, optimal level of testosterone for the single most visuospatial weighted real world tested task is above that of a professional male athlete in peak condition and his performance improves greatly with testosterone supplementation. 1/2pic.twitter.com/qKzXIzpX3l

Somewhere below the first red line is when Bonds reacted to McGwire and Sosa eclipsing him (due to test supplementation) and joined in on it. This is better evidence than any possible study because all actors have skin in the game. No MLB hitter ever chose to suppress test 2/2

I was going to link to Barry Bonds too. His ex-girlfriend said he started experimenting with PEDs in 1999 in reaction to McGwire-Sosa adulation in 1998, got serious in 2000, hit 73 homers in 2001, 232 walks in 2004. How much due to more strength, how much to eyesight improving?

I recall him stating how well he was seeing the ball - statements made while he was supplementing.
