THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
If IQ isn't a valid concept, no concept in psychology is valid.
Conversely, IQ-denial could cause real harm by stalling the development of such interventions.

The idea of imperfect competition leading to technological advancement can be mapped onto education/early learning and social determinants of health. /2
Market forces lead to suboptimal investments in health and education, especially social determinants of health and early learning. (Invest early, invest often for biggest rerurns.) /3
Public policy can provide the "monopolistic" investment that optimizes (at least improves) productive potential of every person in society, not discounting the potential of the poors and the marginalized. /4
This is exactly what we are going to need more of in the next few years, as the Global North ages rapidly and we are faced with dependency ratios that look like the 1960s, but with half the growth. That working are population will need all hands on deck. /5
In short, after a lifetime of being told that markets can do the job if you just get out of the way, we are entering an era where we will need more public policy interventions to optimize growth and well being./6

(1) Kushner is worth $324 million.
(2) Since 2016, Kushner has connived, with Saudi help, to force the Qataris (literally at a ship's gunpoint) to "loan" him $900 million.
(3) This is consistent with the Steele dossier.
(4) Kushner is unlikely to ever have to pay the "loan" back.
2/ So as you read about his tax practices, you should take from it that it's practices of this sort that ensure that he's able to extort money from foreign governments while Trump is POTUS without ever having to pay the money back. It also explains why he's in the Saudis' pocket.
3/ It's why the Saudis *say* he's in their pocket. It's why emoluments and federal bribery statutes matter. It's why Kushner was talking to the Saudi Crown Prince the day before the murdered Washington Post journalist was taken. It's why the Trump administration now does nothing.

Jared Kushner has a net worth of almost $324 million. But it appears that he paid little or no federal income taxes from 2009 to 2016, according to a review of confidential financial documents obtained by NYT. https://t.co/pMQDeCeDNq
