every article that compares people who hold job 'x' with the percentage of the population with trait 'z' makes the very assumption you are blind too. the issue is like wondering why sprinters and endurance athletes are no evenly distributed at the olympics in the various events. (eg, a marathoner is not a crap athlete because they cannot sprint).

xx and xy simply puts different brain chemistry at work. it doesn't mean that the variation disqualifies anyone from anything. the issue is much, much more subtle (like fast twitch vs slow twich muscles in athletes).

oversimplyin it simply makes a mockery of understanding & analysis.

the fact that you use 'brute strength' as an obvious irrelevant characteristic seems to play into this ignorance. ('brute strentgh' doesn't even matter amongst most athletes in most endeavors, at best its a gating criteria, but again what about endurance vs speed vs hand-eye co-ordination vs tactial application of effort?).

...and there's loads of science if you are bored
