Few people actually read this, which is a shame because the science is interesting for historical purposes, and the fulltext of his famous fallacy is rarely read. I believe this is a pity because it is really obvious when you actually read it. Lewontin, R. C. (1972). “The Apportionment of Human Diversity”. Evolutionary Biology. pp. […]

Antonio Regalado is providing us with a recent series of the arguably best informed (compared to Guardian, Nature news etc.) popular science articles on genomics and its relevance to modern eugenics (embryo selection or genetic engineering) as well as the group differences causation question. www.technologyreview.com/s/609204/eugenics-20-were-at-the-dawn-of-choosing-embryos-by-health-height-and-more/ www.technologyreview.com/s/610251/forecasts-of-genetic-fate-just-got-a-lot-more-accurate/ www.technologyreview.com/s/610339/dna-tests-for-iq-are-coming-but-it-might-not-be-smart-to-take-one/ As background for some of these, I had […]

It has been noted that East Asians are positive outliers for the latitude ~ IQ pattern, they’re too far south for their high IQs. Some possible reasons for this are: The peoples evolved further north and migrated south in recent times, and their intelligence level is related to their recent origin, not current location, just […]

Most environmentalists have by now given up denying the existence of racial gaps in head size, but they only retreated a few yards: Nisbett, R. E., Aronson, J., Blair, C., Dickens, W., Flynn, J., Halpern, D. F., & Turkheimer, E. (2012). Intelligence: new findings and theoretical developments. American psychologist, 67(2), 130.

I found some genetically informative studies on the benefits of marriage: Does marriage inhibit antisocial behavior?: An examination of selection vs causation via a longitudinal twin design. Accounting for the physical and mental health benefits of entry into marriage: A genetically informed study of selection and causation. Marriage and Involvement in Crime: A Consideration of […]

While I am re-writing our PING study to become a substantial target article, John is sending it to various journals in the mean time to poke about their editorial biases. Here’s a recent reply, which was thankfully quite up front about the bias: From: Frontiers <noreply@frontiersin.org> Sent: Monday, September 25, 2017 5:05 PM To: j122177@hotmail.com […]

How easy is it to get provocative findings using mainstream methods published? Well, it depends on how provocative. Here’s a second round of generally nonsensical reviews for our PING paper (which you can read here and judge yourself: a good chunk of readers of this blog are themselves researchers and don’t need others to review […]

Readers will perhaps recall that I tried to come up with some metrics for the polygenicity of a trait back in 2016. Well, there’s a new preprint now: Estimation of complex effect-size distributions using summary-level statistics from genome-wide association studies across 32 complex traits and implications for the future Summary-level statistics from genome-wide association studies […]

Woodley reminded me of the dysgenics for health outcomes by linking me to a study about the increasing rates of cancer. I had first reached this conclusion back in 2005 when I realized what it means for evolution that we essentially keep almost everyone alive despite their genetic defects. The problem is quite simple: mutations […]
