Rôle of Testosterone
When a male primate wins a battle his testosterone level rises; when he loses, it drops. Presumably this helps prevent needlessly refighting a battle because the loser is discouraged. Unfortunately, this mechanism spills over into political battles that never end such as poor against elite, gay against bigot, rationalist against religion, democracy against tyranny, triggering needless capitulation.
