wth. If I read that right, he just stated that intelligence is something inherited.

    There is huge difference between saying 1. Smart parents -> Give their kids more exposure -> More Exposure and guidance make the kids smart 2. Smart parents -> kids inherit their smartness. Greg was talking about genes , or case 2, and not case 1. which is what I think is unsubstantiated.

    All the existing data says it is largely inherited The existing data say "partly" rather than "largely." There is still a substantial influence of environmental factors found in any study of "broad heritability" (which is a characteristic of groups, not of individuals) of IQ. And at the individual level, there is a very large malleability of IQ through the best known interventions. Important data showing the powerful effect of environmental influences on IQ include the trends in raw scores on IQ tests over time in most countries of the world, resulting in the need to renorm IQ tests every half generation or so. All these data and more can be found cited to primary sources in Intelligence and How to Get It: Why Schools and Cultures Count by Richard E. Nisbett, http://www.amazon.com/Intelligence-How-Get-Schools-Cultures/dp/0393065057 http://www.amazon.com/Intelligence-How-Get-Schools-Cultures/... a recently published book that is well worth a read.

The correlation between parental income and IQ also holds for adopted kids, which makes it hard to blame genetics: http://bit.ly/2RzLIp http://bit.ly/2RzLIp

  Assuming parents adopt at random...?

The way I have always understood it, being smart isn't an extra above and beyond sort of thing(except for the truly gifted). It is avoiding all the possible ways of being dumb: getting good nutrition, getting enough sleep, avoiding diseases, getting new and interesting experiences, etc. Also while IQ does correlate well with income in general After you get to a certain level not so much(think professors and engineers vs upper level management )
