There IS definitely a link between excessive testosterone and the lowering of sustained logic, reason and mental stability and order. (Just as there is similar evidence liking excessive estrogen with similar behaviors among women) What happens to people, both men and women when they are on steroids? That's been well established in the medical sciences for decades.
Except that it hasn't. If you're thinking about the so-called "roid-rage" phenomenon, it is mostly media created and in any case has nothing to do with normal uses or levels of testosterone. Remember that people who use steroids to get bigger muscles use more than 10 times the replacement dosage(!)
Without looking at the code or the commits...
