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! — 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 […]

Richard Herrnstein, (1971), IQ, The Atlantic Had been looking for this one for years. Gwern managed to find it. I’ll host a mirror here. Perhaps the most interesting thing about the article is the introduction written by the editors. It ends thus: The Jensen report (as this article has come to be miscalled} dealt with […]

It could probably have been resolved decades ago, and definitely within the last 10 years with genomic data, yet it is still not. Why? Essentially, it’s because of bias in academia. It begins early: data access, then there’s authors’ own publication bias, then finally editorial and reviewing bias (all caused by lack of political/belief diversity […]

Given enough motivation, QRPs, biased reviewing and time, one can build an entire literature of studies proving anything. There’s plenty of all of these to prove left-wing ideological beliefs (and libertarian in economics). However, it is much harder to QRP large N datasets to give preferred results. So, what do large scale studies show about […]

Next up in my review series I picked something anti-libertarian. I ended up with We wanted workers, based on a recommendation by Heiner Rindermann. It turned out to be a great choice. Borjas is my type of researcher, in his words: One underlying theme of this book is that viewing immigrants as purely a collection […]
