35 Myths About Human Intelligence

Versión en español de esta entrada – Spanish version of this post Earlier today I submitted the final text for my upcoming book In the Know: Debunking 35 Myths About Human Intelligence. It feels good to have it in the hands of my publisher. There is still some work to do, but most of it

Mindset theory in jeopardy after 2 new studies

A few months ago, I identified a problem with mindset theory studies in the post-replication crisis era. Apparently, mindset interventions only work if Carol Dweck is a co-author on the study. That is not an indicator of a strong, enduring psychological phenomenon. Two more studies have been published in the past few months that do

Ancient DNA: A window into human nature and change

I read an article this week which described an analysis of ancient DNA samples from Portugal to understand how prehistoric populations mingled and merged to form the modern Portugese gene pool (Martiniano et al. 2017). This type of article is not unusual. Similar studies have been conducted on populations from every inhabited continent. What interested

What’s new for STATISTICS FOR THE SOCIAL SCIENCES, 2nd edition

Today, I submitted the manuscript for the second edition of my statistic textbook, Statistics for the Social Sciences: A General Linear Model Approach. This book has been a labor of love, and it has been a great pleasure to revisit the text and make revisions. The first edition has been well received, with the comments

Analysis of introductory psychology textbooks: 2 years later

Exactly two years ago today, my colleagues and I published an article in Archives of Scientific Psychology in which we analyzed the discussion about intelligence in each book and screened it for inaccuracies and logical fallacies (Warne et al., 2018). We found that over three-quarters of introductory psychology textbooks had at least one factual error

Intelligence research: An example of Thomas Kuhn’s “normal science”

Psychology is a mess. And I don’t say that because of the consequences of the replication crisis. No, compared to biology and the physical sciences, psychology is a mess because it has no unifying theory. Biology has evolutionary theory as a powerful framework for understanding everything from ecology to genetics. Chemistry has atomic theory, which

Standardized tests: NOT designed for standardized minds

In response to my list of 35 myths about human intelligence that my upcoming book tackles, I have had people ask me what intelligence myths didn’t make the cut. It is a fun thought experiment to think how the book would be different with a different mix of incorrect ideas to address and correct. There

Lewontin’s bait-and-switch: A strategy to undermine genetic explanations of behavior

Coinciding with the launch of his book, Human Diversity: The Biology of Gender, Race, and Class (see my thoughts here), Charles Murray had an opinion piece in The Wall Street Journal where, among other things, he discussed the importance of polygenic scores in making predictions. Polygenic scores are scores derived from DNA variants. Bits of

Start teaching about intelligence!

Last week, I had a new article published by the American Psychological Association in Teaching of Psychology (Burton & Warne, in press). The article has two parts: an analysis of course catalogs, and an outline for a university-level intelligence course. Course Catalog Analysis My then-student, Jared Z. Burton, identified 303 of the top universities in

Initial thoughts on Charles Murray’s HUMAN DIVERSITY: THE BIOLOGY OF GENDER, RACE, AND CLASS

Today, Charles Murray’s latest book, Human Diversity: The Biology of Gender, Race, and Class was released. I won’t write a full review of the book here because there is a possibility that I will be writing one for a scholarly journal. Having read the main text of the book, though, there are some thoughts that
