It doesn't seem plausible that war or murder leads to a positive force on someone's character or natural ability. There are many great tragedies where the flower of a nation's manhood has been lost in war and left the country in a worse off position to grow it's populace. The Battle of the Somme for one.

Most religions and ethnic groups has at least one persecution story if not centuries of them, I don't see the evidence that it leads to a uniform positive increase in outcomes.

Wow! Does it work too for the blacks? Maybe, blacks run fast to escape from whites on electric cars!! And women! Women are prettier than men to manipulate men!!

Please, don't do that. Please DON’T.
