I have been complaining to colleagues about this one for several months. Of the various criticisms of this method, I don’t recall one pointing out this problem. I don’t have time to do some simulations right now, but I did some quick illustrations. The same problem holds for the item-level analyses (these are done using […]

In reply to: Scott Alexander’s Learning To Love Scientific Consensus. Actually, I have planned (in my mind) a somewhat longer post on my take on the ‘correct contrarian cluster’, or how to make up your mind of what to believe on controversial topics. But I certainly don’t have time to write that now, so instead […]

Identity between humans of all groups and non-human AI demonstrates IAT reflects statistical pattern detection rather than bias t.co/h6S2PChi0N — Timothy Bates (@timothycbates) April 14, 2017 Humans have stereotypes, that is, they hold beliefs about groups of people. When examined, these beliefs tend to reflect reality quite well, sometimes very well (for review, see Jussim’s […]

Just a quick post to summarize or reference the evidence for various claims and mistakes I made. The interview Previous interview with Tara McCarthy I should have done a post on this as well instead of spending so much time replying in the comments. Oh well. From now on I’ll just do a commentary post […]

On the commentariat here, and why I don’t think I can be associated with this community, despite liking the blog. My reply, as found in the comments. Most of it seems to be just rewritten stuff from RationalWiki’s collection of inaccuracies. I repost my reply below here for prosperity, and also for those too lazy […]

Because I hate seeing solid contributions go unnoticed. Few remember Barbara Stoddard Burks for the early pioneer of behavioral genetics she was. She doesn’t even have a Wikipedia article. I will fix that shortly. In their article on the sociologist’s fallacy in interpretation of familial data, Rowe and Rodgers (1997) mention Burks thus: The issues […]

I don’t have time to provide extensive citations for this post, so some things are cited from memory. You should be able to locate the relevant literature, but otherwise just ask. Haier, R. J. (2016). The Neuroscience of Intelligence (1 edition). New York, NY: Cambridge University Press. Because I’m writing a neuroscience-related paper or two, […]

www.gwern.net/Embryo%20selection#counteracting-dysgenics Gwern has a very long and detailed post/page on embryo selection and related matters. You should definitely read it. He has just added a new section on counteracting dysgenics — the genetic evolution of undesirable traits — and asked for my comments/thoughts. The background for the discussion are the recent genomic findings supporting dysgenic […]

Rnotebook: rpubs.com/EmilOWK/immigrant_IQ_Danish_draft Because I was discussing this dataset with a friend, I decided to reexamine it. Examining this dataset was my first reviewed paper (Kirkegaard 2013). It was manually done in Excel with no statistical guidance. So I had to work out everything myself based on googling around for formulas. My first write-up was not […]

Nisbett’s 2009 book on intelligence, Intelligence and how to get it, is a goldmine of stupid claims that one can quote-mine for introduction and discussion sections of papers. For instance, Nisbett tries to argue that brain size is not causal for intelligence! He writes: The correlation between cranial capacity and IQ is probably about .30-.40 […]
