1/2 A few days ago, a health service provider phoned to say that my test was being cancelled because the insurance provider wouldn't cover it. I asked how much it would cost to pay it myself. The answer was $373. I realize that $373 is a sum that many people can't afford to pay.

I revere the 1960s NASA. The 2020s NASA is a joke. DOGE, how about stripping NASA of all its launch vehicle responsibilities & prepare a list of the useful functions that NASA still serves. Or are there any?

Great title.

Does anyone find this problematic? (No, I won't test the waters by posting the same picture with the caption "Scientists Found a Cure for Progressivism")?

Very excited (and a bit nervous) to announce that I will be hiring two Postdocs for my new group(!) in Copenhagen to study the Neanderthal and Denisovan DNA which survives in present-day humans. Retweet will be much appreciated :)

From www.johnderbyshire.com/Opinions/Dia.... I post it because connoisseurs of puns will want to add it to their collections.

Charles Murray praising racist scumbag Steve Sailer in May 2024 at the American Enterprise Institute, @americanenterprise.bsky.social which fully supports Murray's racism:

1/2 Advice for small colleges with good-but-not-top-tier prestige: The first among you to announce that henceforth admissions will be based exclusively on test scores will immediately become a safety application for 1500-1600 SAT students who are subsequently turned down

I don't know if they can make good on it, but this is the most inspiriting op ed I've ever read.

1/6 Day 2. Are mental tests biased against Blacks? This topic has been examined minutely for decades. The two most powerful ways to check for bias are measurement invariance and predictive validity.
"Measurement invariance" asks whether a test measures the same construct across groups.

I just wrote a 6-part thread, and at the end the I couldn't successfully click on the "Post All" box. What might I have done wrong?

I neglected to specify that the graph is based on year of test administration, not birth cohort.

Are mental test scores different for American Whites, Blacks, Latinos, and Asians? The answer is yes, with the means for each group consistently ordered from high to : Asian, White, Latino, and Black. The differences are usually larger on cognitive batteries designed specifically to measure the

Here's the plan: Probably the most taboo of all topics involves IQ differences across ethnicities. The topic also has two other characteristics: 1) A great deal is known confidently, with lots of replications and tests for confounding, and 2) hardly anyone on the left is aware of that body of

Over on X, there is amusement at how easy it is to get kicked off Bluesky. So I will test it out with a few emails, starting with a table and no commentary from the 2023 College Board report for 2023. If this causes no problem, I will follow it up with commentary and see what happens.
