I think this is a cop-out.

I've met tonnes of asians who are great at social settings. Just like I've met tonnes who aren't. Just like I've met tonnes of (black|white|hispanic|etcs) ...

I have noticed that asians engineers in particular, in a corporate setting, tend towards "work hard + wait for reward" strategy. Maybe it's the intersection of what draws us to engineering and upbringing that results in this?

But yeah, to say it's genetic is silly :)
