In this post, I am going to go over a number of different predictors and correlates of discriminatory behavior and prejudiced behavior, such as racism, sexism, homophobia, etc. The main topics discussed will be personality correlates of discrimination, cognitive functioning of people who are more discriminatory towards others, and the heritability of discrimination.Continue reading
A while back, I wrote a post discussing the potential for psychedelics to increase intelligence. There are many reasons this is of particular interest. For one, we have been looking for an “IQ pill” for a long time now with no luck. The main choices are nootropics like modafinil, Adderall, etc. Unfortunately, these don’t seem to work too well. Second, there are obvious benefits to a higher IQ, particularly in the labor market (Gwern, 2016; Strenze, 2015; Salgado and Moscoso, 2019). Third, as I will talk about shortly, even a very small, but significant increase in intelligence due to psilocybin may have some interesting implications for the so-called Stoned Ape hypothesis.Continue reading
One particular concern with cannabis legalization or drug legalization in general is that it may reduce the amount of productivity. The classic story goes like this: people use drugs, particularly cannabis which has more sedative effects than the other drugs up for consideration, and they become addicted to them, become lazier, somtimes leaving their jobs, going on welfare, etc. and getting sucked into a life of drugs. Perhaps this is a more extreme version of the argument. If so, I am also disagreeing with the moderate version. Anyways, does it hold up?Continue reading
In this post, I want to detail some evidence as to how the ‘Black’ plague or bubonic plague caused a change in European genetic makeup, particularly that concerning intelligence. A few years ago, a study made mainstream news showing that Europeans have less susceptibility to HIV, and generally have stronger immune systems than before, because of the black plague (Laayouni et al., 2014). Now, that finding is not actually the focus of this post, but it allows the ideas within the post to become more realistic.Continue reading
This post is going to lay out the argument that rural areas tend to have lower average IQs than urban areas as well as any opposing evidence.Continue reading
NOTE: This article was posted on someone’s Twitter on 7/20/2020 which prompted me to correct some errors I remembered having in it. The first sentence, which the tweet quoted to my dismay, read “there is a moderate to strong relationship between criminality and intelligence.” This was a misrepresentation of the data on my part, and I changed it to what it is now (below). I also responded to some criticisms about “high IQ people just being less likely to get caught” and deleted a couple sentences.
There is a low to moderate correlation between criminality and intelligence, but the average IQ of criminals and non-criminals is large and sociologically important. The evidence for this will be documented below, though explanations for why this is will be saved for another day:Continue reading
