In pure-visual ability, above data clearly indicated East Asian ability. Naturally they excel in STEM field.
But in silicon valley, South Asian engineers move up easily in corporate world. Advancing in corporate world is depending more on social skill than engineering skill. South Asian also display strong social skill as result of people from high density origin.
Some Chinese American engineers told me about their experience in silicon valley. They did most work while Indian colleagues seems not able to do much.

Good social skill gets all credits for career advance.
