There is a lot of research on the link between crime and cognitive ability. (For criminal outcomes, see the problems in my previous post.) E.g. Is the Association between General Cognitive Ability and Violent Crime Caused by Family-Level Confounders? We linked longitudinal Swedish total population registers to study the association of general cognitive ability (intelligence) […]

I am watching Brian Boutwell’s (Twitter, RG) talk at a recent conference and this got me thinking. What are we measuring? As far as I know, there are typically two outcome variables used in criminological studies: Official records convictions. Self-reported criminal or anti-social behavior. But exactly what trait are we trying to measure? It seems […]

Many people listen to some kind of music while working, or perhaps to some kind of colored noise. Many people will swear that this works. There are multiple ways it can work: Increases work performance. Increase work enjoyment (positive mood effect). Makes work seem to go faster (time experience effect). They are not necessarily causally […]

There are some sites that have scraped the average movie ratings at various sites such as IMDB, Rotten Tomatos and Allmovies. Here is one particularly good (and still online) job. Still, this is all aggregate data. Perhaps we are more interesting in how people rate movies. One does have the option to make one’s profile […]

Noah Carl has been investing the relationship between cognitive ability and political opinions aside from the usual confused 1-axis left-right model. Specifically, looking at the economic freedom and personal freedom axes (á la this test). He did this in two datasets so far, covering the UK and the US: Verbal intelligence is correlated with socially […]

In the fallout of the OKCupid dataset release, some people wrote a complaint letter to Aarhus University. I haven’t read the letter, but Aarhus University has now replied to it: Reply to Oliver Keyes et al Basically, the letter affirms everything I’ve already said, namely: University was not involved, so: Their ethics rules do not […]

Normally, testing colorism or other causal models of why human racial traits have nonzero relationships to socioeconomic outcomes requires that one has the following data: Measure of racial ancestry Measures of racial appearance Measures of socioeconomic outcomes such as income or educational attainment Path model wise, one can think of it this way: Discrimination models […]

OSF has now suspended the entire repository, not just deleted the user datafile. Not sure why this is the case. The paper (PDF) is available here. Edited to add: The repository is closed due to a DMCA request sent by OKCupid which is currently being investigated. Edited to add2: For those wondering what information was in […]

In a recent paper, Beaver et al looked at the relationships between crime, gender and sexual orientation: This study examined the association between sexual orientation and nonviolent and violent delinquency across the life course. We analyzed self-reported nonviolent and violent delinquency in a sample of heterosexual males (N=5220–7023) and females (N=5984–7875), bisexuals (N=34–73),gay males (N=145–189), […]

Data from the OKCupid project. In light of a recent paper examining who prefers to date within their own religion, I recalled that there was a question about this in the OKCupid dataset, except that it is for race: “Would you strongly prefer to go out with someone of your own skin color / racial background?” […]
