I don't think Watson is after some narrow, technical relationship between a particular gene and a particular ability. Instead, he make wide, unconstrained and unscientific generalisations which can only be defended by shrinking what he says.

To quote Watson: “I think now we’re in a terrible sitution where we should pay the rich people to have children.. if we don’t encourage procreation of wealthier citizens, IQ levels will most definitely fall.”

Now, any non-indoctrinated human can understand that the issue of "perfect" phenotype is not about modern groups at all;

TO be clear - it is Watson who is making racial arguments about Irish, Black and Jewish "races".

The whole point is what you are saying - the "perfect" human isn't about racial selection. It's Watson's clear racism (and he admits he is racist!) that makes it so dangerous.

This isn't some indoctrination thing - it's anyone who has read the Nazi or Communist "scientific" justifications of their theories that should hear alarms.
