In contrast, in @NYMag Andrew Sullivan, goes the opposite way, approving of Reich, immediately zeroing in on the race+I.Q. issue, checking in with @charlesmurray of The Bell Curve fame, etc..http://nymag.com/daily/intelligencer/2018/03/denying-genetics-isnt-shutting-down-racism-its-fueling-it.html …

Reich skates clear of saying races differ in intelligence, but intelligence IS the cognitive trait he's interested in, judging by his text. Like it or not, it's the one trait he gives over five paragraphs to. From the editorial:pic.twitter.com/rxPe56dA8Z

Same text with references added. These reports represent a series of newly successful gene hunts for the genetic determinants of I.Q. or of "educational attainment." This is new and cutting edge research Reich knows about.pic.twitter.com/U7Hm1ujJfS

We just published an article about how such gene discoveries can be turned into a score that predicts an indvidual's I.Q., from their DNA. Here's that story about DNA-based IQ tests.https://www.technologyreview.com/s/610339/dna-tests-for-iq-are-coming-but-it-might-not-be-smart-to-take-one/ …

Here's a previous thread that provides more details on polygenic scores for intelligence.https://twitter.com/antonioregalado/status/980846423670427648 …

Currently, DNA assessments of an individual's IQ are questionable because they are not very accurate.

But pinpoint accuracy less important when looking at averages. What this tech really good for is looking at GROUPS, describing GROUPS, or dividing people into GROUPS (say, by IQ)

To me, Reich seems to be indicating that this same emergent technology, of modelling traits using polygenic scores, may eventually VERIFY that one group has, on average, higher polygenic scores for intelligence than another group.

Luckily, such a comparison is NOT POSSIBLE to do right now. First reason, as Reich notes, all the genetics data is from Europeans. No one has similar scope of data on other races.

It is possible and it has already been done. Educational attainment alleles discovered in Europeans have been under recent selection in East Asians, Probably not a coincidence their average IQ is 105. http://www.genetics.org/content/genetics/early/2018/01/18/genetics.117.300489.full.pdf …pic.twitter.com/63MLbZGdg5
