Scientists Tie 52 Genes to Human Intelligence

As i said, given an ideal environment, intelligence is purely genetic. This whole focus on environment is important, because we ought to have it right for our kids, but its like saying that a cars performance is about oil brands and road conditions. No, a better engine makes a better car and developing the engines is exciting and important because we know how to make good oil and roads and once the roads are paved and refineries operating, most of the progress will be understanding the engine. Yes you need roads but being able to understand and possibly select and manipulate genetics associated with intelligence will produce huge, groundbreaking changes that will make the world much, much better.

"Given an ideal environment" is a pretty big "given". You might as well say "given an ideal environment, X is purely genetic for any human characteristic X.

First, an anecdote about knowing someone smart related to a physicist means hardly anything. I happen to personally know two prestigious scientists (NAS, HHMI fellows) who both have children you'd consider very mediocre (one in his 4th year of community college).

I am not taking the position that genetics does not contribute to intelligence. Of course it does. Like you pointed out, humans are smarter than other species, like apes. What we are trying to determine here the degree to which systematic genetic variation within our own species contributes to intelligence. One thing we know for sure is that this claim...

> There is no doubt that intelligence is purely genetic.

...is certainly wrong. Oddly enough, you've already conceded that, twice:

> Yes, environment counts but if you give everyone their own personal most ideal environment,

> given an ideal environment, intelligence is purely genetic.

That's equivalent to saying both genetics and environments affect intelligence; which is equivalent to saying intelligence is not purely genetic.

I got too caught up in the wording of your first post. I agree completely.
