I want to try to explain something about testosterone and performance, since it has become the ‘fixation’ and the ‘the fix’ for inclusion policies for both DSD and trans athletes. So here’s a thread to ‘debunk’ and explain why T level, per se, is not quite the right place to look

The first thing an expert would ask when seeing a tweet like Zach’s is “what’s the base rate of drop-outs”? From there, they’d understand context and appreciate that elite athletes actually “fail” infrequently given the set of factors they face compared to the general population.

But what mistakes did they make to “have a bad day”? Recall they are the experts. Experts should know how not to have a bad day. That’s my point.
In scientific experimentation measuring performance effects, it’s critical that performances must be highly reproducible. That’s why reproducible experiments are more valuable than accepting what the experts believe.
But the best is to take the experts’ beliefs and subject them to rigorous testing particularly in an attempt at disproof. That’s how science is meant to work.
It’s difficult but it’s why science evolved as a special human endeavour as recently as the last 500 years. Before that we only had beliefs.
