In evolutionary biology, there is a hypothesis about sex ratios: Trivers-Williard hypothesis. It has been noted that males have higher dispersion in their fertility than females have, a finding that is also true in humans (one, two, three). If resources are related to fertility — which they are in many species and used to be […]

Disclaimer: I did not read Rushton’s seminal book on the topic. I was only first recently able to obtain a complete electronic copy (i.e. not abridged version). I did in fact only skim this literature. I don’t have time to work on this, but I’d like others to do so, hence I put the labor […]

A reader asked me to comment on the predictions/musings by Marty Nemko at his blog. I had never heard of him before, but he’s some kind of coach, radio host and columnist popular in the Bay Area. The decline in good jobs. My optimistic side predicts that improved education and gene editing to improve intelligence […] I had seen references to this book in a number of places which got me curious. I am somewhat hesitant to read older books since I know much of what they discuss is dated and has been superseded by newer science. Sometimes, however, science (or the science culture) has gone wrong so one […] Richard Lynn is so nice to periodically send me books for free. He is working on establishing his publisher, of course, and so needs media coverage. In this case, he sent me a new book on the Roma by Jelena Cvorovic who was also present at the London conference on intelligence in the spring […] If you read the original essay, there is not much to recommend about the book. It taught me very little, has no data tables, no plots, no figures. Numbers are only mentioned in the text and sources are only given in the back of the book. There were a few interesting works mentioned, […]

Seriously. Read it. Behavior Genetics (Impact Factor: 2.61). 03/2014; DOI: 10.1007/s10519-014-9646-x Source: PubMed ABSTRACT I argue that the g factor meets the fundamental criteria of a scientific construct more fully than any other conception of intelligence. I briefly discuss the evidence regarding the relationship of brain size to intelligence. A review of a large body of […]

This book is very popsci and can be read in 1 day for any reasonably fast reader. It doesnt contain much new information to anyone who has read a few books on the topic. As can be seen below, it has a lot of nonsense/errors since clearly the author is not used to this area […]

We have a neanderthal genome. It is possible to estimate an individuals neanderthal ancestry. 23andme does this. It is possible to use the admixture study design to see what the effects of some kind of ancestry origin is. What are we waiting for? They can use the SNP datasets they have used GWA studies for […]

This book is fairly short and is mostly about sexual selection and sexual antagonism. While other EP lit. uses animal examples, this book is literally full of them. Lots of interesting comparisons with all kinds of birds, for instance. On the continuum of biology — psychology of EP lit., this one is definitely closer to […]
