I was working on a study and while doing so, I updated all my R packages. To my surprise, this changed the results in my analysis to a degree that it caused a change in the conclusion. I suspected it was due to an update in the psych package. The update notes read: Bug fixed […]

This is just a brief post summarizing some stuff because I don’t have time to do more right now. Noah Carl asks me: Can you point me to some evidence (e.g., a blog post) on “PC-bias” in polling in recent years? It is hard to establish biased polling. One has to: Obtain datasets of polling […]


Brief summary of thinking: The war on drugs makes it difficult or impossible to study drugs on the ban list. A drug’s presence on the ban list is primary due to psychoactive effects. Medical researchers and companies are either too incompetent or too corrupt/incentivized to perform proper drug comparison studies. The efficacy of drugs is […]


I’ve decided to re-do my old and not too well done 2013 study. It goes like this, for multiparty democracies: Countries differ in the number of houses: 1 vs. 2. Countries differ in the number of seats in these houses. Usually, to get a party on the ballot, one must first collect X signatures. This […]

Syncthing is a open source synchronization application. It’s a replacement for the closed source Bittorrent Sync (BTS).  If you are currently using BTS, I recommend switching because 1) it’s closed sourced, and 2) owned by an American company, and thus 3) likely to implement NSA-style backdoors. This is made more likely by the fact that […]

Gwern has an old note on the US’ offer to buy Greenland from Denmark after WW2. Aside from the usual nationalist feelings about land, the Greenland population is ~25% genetically Scandinavian, presumably mostly Danish. This number is from genomic studies, the sociological counts differ somewhat because they include the mixed persons in the Inuit group […]

Lots of published psychology studies don’t replicate well, in particular cute things like interactions, counter-intuitive or priming effects. In general, traditional behavioral genetics studies have replicated well. This is not surprising because basically the same method (ACE fitting) has been applied to lots of large datasets, and studies that use consistent methods on large datasets […]

Back in January, Steve Hsu did an interview with Daphne Martschenko who is a phd candidate at Cambridge in education. She’s basically doing science journalism on behavioral genetics as far as I can tell. Now there’s a new interview up. I have some comments to it because Steve was a little too nice. Bias from […]
