There’s a highly interesting new paper out: The Genetic Basis of Mendelian Phenotypes: Discoveries, Challenges, and Opportunities (Mendelians are also known as monogenic disorders because they are inherited in patterns that follow Mendel’s laws.) Abstract: Discovering the genetic basis of a Mendelian phenotype establishes a causal link between genotype and phenotype, making possible carrier and […]

www.goodreads.com/book/show/10753824-regression-modeling-strategies I heard some good things about this book, and some of it is good. Surely, the general approach outlined in the introduction is pretty sound. He sets up the following principles: Satisfaction of model assumptions improves precision and increases statistical power. It is more productive to make a model fit step by step (e.g., […]

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 […]

Note: snarky, critical. Happy to be proven wrong. Edit: after writing this, I found some more evidence, but it’s not particularly convincing either. CFAR, The Center for Applied Rationality, is connected to the Less Wrong/rationalist movement. They offer courses where one can: 4-day immersive trainings in applied rationality; form accurate beliefs; learn to get these […]

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 […]

Along with some other people, I was asked to produce a list of the top 5 books that had the largest influence on me. Five books that have most influenced your worldview @EPoe187 @fsnole1 @hbdchick @DrRobertKing @JayMan471 @KirkegaardEmil @pnin1957 — Ben Winegard (@BenWinegard) June 5, 2017 Note that this is not the same as listing […]

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 have been complaining to colleagues about this one for several months. Of the various criticisms of this method, I don’t recall one pointing out this problem. I don’t have time to do some simulations right now, but I did some quick illustrations. The same problem holds for the item-level analyses (these are done using […]

After the recent London conference on Intelligence, we visited the Science Museum in South Kensington. Unfortunately, we did not have enough time to explore everything, but we did spend some time in the flight section. A number of the texts on display highlight the importance of open science, and are worth posting here. Stalling science […]

I could not find someone that briefly described this problem, so I’ll just do a very quick job at doing so. I take it that this is a common observation that I was just unable to find the right term for. And yes, I appreciate the metaness of this. :) The FOSS fragmentation problem: everybody […]
