Jews also make up about 50% of world chess champions as per that article. Jews are about 0.1% of the world population.
Asians make up about 99.9% of the world's teppanyaki cooks. Are Asians genetically programmed to cook on a large, metal sheet? Italians make up 99% of the Mafia. Are Italians genetically programmed to run front companies and engage in extortion?
Surely you know that being able to perform at the highest levels of a game which requires exceptional spatial reasoning skills is due solely to environment. If Jews were in a different environment they'd completely flop at chess and instead would be needing affirmative action programs to get into a mid-grade state university due to their poor test scores and inability to succeed on their own.
Yes, I'm being sarcastic! :-)
