Sure, but note that the the type of advice Jonah is giving is disproportionately aimed at gifted kids.

So, Chua's technique and Jonah's are indeed aimed at the same population and so we can look at the results that each offers. Chua's two daughters are not a big data sample, however.

Certainly, kids who are pushed to "play the game" succeed in life along all relevant parameters more than those who are not (those Upper East Side kids whose parents prep them for Harvard are going to end up with above average outcomes as compared to the US population). But there are some major confounding variables there, of course.
