I don’t know of any scientific studies, but there’s been a bunch of shows where they put teams of women and men on islands and had them try to survive etc. The results were quite predictable, though I want to note that the producers could have biased things by picking particularly incompetent women and competent […]

Using the crude measures of literacy and numeracy discussed in a previous post, it is possible to quantify the cognitive ability gap for US Black-White in the 1800s. The data come from: A’Hearn, B., Baten, J., & Crayen, D. (2009). Quantifying quantitative literacy: Age heaping and the history of human capital. The Journal of Economic […]

These are the Google Translated versions of the original French. We are trying to obtain regional data for Belgian communes to use for our study, as well as nationality or group level data for general interest. You can see the preliminary analyses here. Needless to say, it is hard to find out what is actually […]

This is beyond even normal levels of stupidity seen in politics and smear attacks. felixonline.co.uk/news/6705/kings-lecturer-sparks-racism-row/ Image form for easier reposting Here’s the data from the DST report: www.dst.dk/da/Statistik/Publikationer/VisPub?cid=20704 Any journalist with even 5% of a brain could have easily verified this. The Norwegian and Finnish data are from Skardhamar et al 2014.

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 […]

This must be the most hilariously trolly study I’ve seen in a while. Understanding the Therapist Contribution to Psychotherapy Outcome: A Meta-Analytic Approach Understanding the role that therapists play in psychotherapy outcome, and the contribution to outcome made by individual therapist differences has implications for service delivery and training of therapists. In this study we […]

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 […]

Since this one is well-covered already, I don’t need to add much. See e.g.: Nintil: Why so few women in CS: the Google memo is fundamentally right Slatestarcodex: Contra Grant On Exaggerated Differences Lee Jussim, David P Schmitt, Geoffrey Miller, Debra W Soh’s writings Math ability and sex Because lots of people keep claiming there […]

I have been tweeting annotated snippets from a WHO report I’m reading. Like this: Improving the health of your own citizens before foreigners? Not good! pic.twitter.com/HOix8gOZOr — Emil OW Kirkegaard (@KirkegaardEmil) August 8, 2017 Basically, the report does a decent job at summarizing the state of the art in 2002, and has some interesting notes […]
