The level of heritability of many traits is far from settled, AFAIK, and given the long shadow of Nazi racial pseudoscience, there is a certain air of suspicion around anyone who researches the topic of heritability too eagerly, at least in the West; China does not seem to have this particular taboo.

And I am not even surprised, the possibility of governments latching onto this and "streaming" people towards whatever they are found to be gifted at, cannot really be dismissed.
