We have a new big paper out: Kirkegaard, E. O. W., & Fuerst, J. (2017). Admixture in Argentina. Mankind Quarterly, 57(4). Retrieved from mankindquarterly.org/archive/issue/57-4/4 Abstract Analyses of the relationships between cognitive ability, socioeconomic outcomes, and European ancestry were carried out at multiple levels in Argentina: individual (max. n = 5,920), district (n = 437), municipal […]

In reply to: nautil.us/issue/48/chaos/what-both-the-left-and-right-get-wrong-about-race www.geneticshumanagency.org/gha/origin-of-race-differences-in-intelligence-is-not-a-scientific-question/ There’s a new kind of ‘environmentalist’ (rather, anti-hereditarian) defense in town, or at least, one that’s not commonly seen. It goes like this: This is the first of a series of blog posts about race and intelligence. My opinions on this topic are, I think, the least popular arguments I […]

Based on: gnxp.nofe.me/2017/05/30/ancient-egyptians-black-or-white/ www.nature.com/articles/ncomms15694 Abstract Egypt, located on the isthmus of Africa, is an ideal region to study historical population dynamics due to its geographic location and documented interactions with ancient civilizations in Africa, Asia and Europe. Particularly, in the first millennium BCE Egypt endured foreign domination leading to growing numbers of foreigners living within […]

I oppose coercive eugenic policies, so don’t try to quote mine my blunt discussion as support for such policies. Hollywood has a new anti-eugenics movie out, called The Thinning. There’s a trailer, and it will likely spoil the entire movie for you, but I reckon it will be crappy anyway, so: For those too lazy […]

On the commentariat here, and why I don’t think I can be associated with this community, despite liking the blog. My reply, as found in the comments. Most of it seems to be just rewritten stuff from RationalWiki’s collection of inaccuracies. I repost my reply below here for prosperity, and also for those too lazy […]

First we had 3 laws, then a 4th. I’ll propose a 5th: All human behavioral traits are heritable. The effect of being raised in the same family is smaller than the effect of genes. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or […]

Note: I found two persons to do this so far. 1. Skills required Ability to copy paste from this Wikipedia page into a spreadsheet. Ability to find the elementary information for a study. 2. Job description A meta-analysis relies on a dataset of information about other studies. One of us collected a large number of […]

Because I hate seeing solid contributions go unnoticed. Few remember Barbara Stoddard Burks for the early pioneer of behavioral genetics she was. She doesn’t even have a Wikipedia article. I will fix that shortly. In their article on the sociologist’s fallacy in interpretation of familial data, Rowe and Rodgers (1997) mention Burks thus: The issues […]

www.gwern.net/Embryo%20selection#counteracting-dysgenics Gwern has a very long and detailed post/page on embryo selection and related matters. You should definitely read it. He has just added a new section on counteracting dysgenics — the genetic evolution of undesirable traits — and asked for my comments/thoughts. The background for the discussion are the recent genomic findings supporting dysgenic […]

Nisbett’s 2009 book on intelligence, Intelligence and how to get it, is a goldmine of stupid claims that one can quote-mine for introduction and discussion sections of papers. For instance, Nisbett tries to argue that brain size is not causal for intelligence! He writes: The correlation between cranial capacity and IQ is probably about .30-.40 […]
