Lord Kelvin on quantification and scientific knowledge

Being annoyed by some of the usual qualitative drivel masquerading as science (see almost any tweet by @RealPeerReview), I was moved to make a nice background/poster. https://en.wikiquote.org/wiki/William_Thomson A slide from some anthropologist said of Galton that he “Worshipped at the alter of quantification”. That’s a nice way to put it!

Celebrating an early female pioneer: Barbara Stoddard Burks

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…

The neuroscience of intelligence: very preliminary because of power failure and lack of multivariate studies

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,…

Evolutionary Psychological Science, 1-19. For over a century, social scientists have predicted declines in religious beliefs and their replacement with more scientific/naturalistic outlooks, a prediction known as the secularization…

European produced culture

This is a break from the usual technical sciency stuff! I talked with John Fuerst about how weird it is that people all over the Western world were watching the same American produced cartoons as a child. A kind of pan-Western world environmental effect, if there are any long term effects of watching these, aside…

The Polgár sisters of … camming?

h/t to SSC for leading to me discovering the most curious thing. So it turns out there’s a camgirl with an interesting blog featuring things like evidence-based camgirling (why not?) and a subjective experience based model of LSD tripping (based on doing LSD for every week for 10 months?!). Looking over her Twitter reveals that…

Comments on Gwern’s Counteracting Dysgenics

https://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…

The reverse time reversal heuristic?

Gelman proposed the time reversal heuristic when evaluating discussions about failed replications. One helpful (I think) way to think about this episode is to turn things around. Suppose the Ranehill et al. experiment, with its null finding, had come first. A large study finding no effect. And then Cuddy et al. had run a replication…
