SuperTool:
Funny you should mention that. I ran into a Chinese friend of mine at Costco two hours ago and I said to myself sheezh, she's just about the smartest person I know and she's, well, goose bump size.
But, I agree with you. I have a Japanese friend as well and she went to Cal Tech and is now a research chemist. No grass under her feet.
I suspect the study has little validity. Frankly, I have no faith in psychometrics anyway. Maybe it's because I'm too stupid to understand it.

BUT, BUT, BUT, I HAVE A LARGE CHEST!
