The “genetics of schizophrenia” area of research—which began as a eugenics program—is currently in disaster mode and awaits its endpoint.

In an ironic historical twist, the criminal behavior of these two German men may have been influenced by "syndromes" associated with each other's names.

"Kallmann Syndrome." FJ Kallmann was a fanatical racial hygienist and schizophrenia family/twin researcher during the Third Reich. He advocated forcibly sterilizing "schizophrenic taint carriers" and some of their relatives. Had to leave Germany in 1936 due to Jewish ancestry.

I wrote about the underlying problems with this comparison here: https://t.co/W6hcrGgBjM
I wrote about how population stratification in genetic analyses led to a decade of false findings and almost certainly continues to bias emerging results. But we are starting to have statistical tools to sniff it out. A 🧵:

Comparing polygenic scores across populations like this produces completely meaningless results that will tend to recapitulate crude environmental correlations. This approach has now been critiqued dozens of times and it keeps rearing its head ...

@indexmetals @AlexTISYoung @gsliwoski @paulnovosad @herasight The project to understand IQ biology through GWAS has been such a failure they don't even bother reporting the individual associations any more in papers. We know it's enriched for the brain, possibly neurons in the brain 🤷

Murray and most of race twitter has apparently been fooled by this completely fabricated analysis purporting to show African ancestry is associated with IQ. People lie on twitter all the time, but this is both more revealing and more disturbing than usual. A 🧵
Proposition: Everything that has been learned about the nature of the B/W difference in the subsequent 56 years of research is consistent with Jensen’s expectations in 1969. I stand ready to be corrected.

For those interested in the eugenic origins of the field of #PsychiatricGenetics, check out this Google AI description of a German-language 1942 article written by Ernst Rüdin, the field's undisputed founding father. https://t.co/V1cZtXSMMU

The decades-old Danish schizophrenia adoption studies by Kety et al are still widely cited. Yet, the genetic findings from these studies were based on deceptive (p-hacked) research practices. My latest detailed description of one aspect of this deception. https://t.co/8WKSSBJtqV

Really? Systematic racism is built into IQ tests, which are designed to produce ethnic but not gender differences. Murray and Pinker assume ethnic diffs are influenced by genetics, when there is no valid evidence supporting WITHIN-group "heritability." https://t.co/sa2Gy13vrP

So what's @charlesmurray up to now? He's been laundering fake analyses that he himself doesn't understand from anonymous race bloggers who can't be bothered to write them up (FWIW "substantive reply" did not come). Not with a bang but with a whimper. https://t.co/pEiqVlNFg8

Eric Turkheimer has a good piece about a bet he made with Charles Murray regarding the genetic understanding of IQ (or, really, the lack of it). Murray being so wrong in his prediction should make us question his world model, but it's also worth commenting on his response.
In 2018, Eric Turkheimer took a bet with Charles Murray, who said that by 2025, the genetics of intelligence would be basically understood. Turkheimer knew otherwise. “I am here to declare that I was more right,” Turkheimer writes.

Over one million people in Italy joined a nationwide strike and protests in solidarity with the Global Sumud Flotilla after Israeli raids on all 42 vessels. The strike—organized by the country’s two largest unions, representing 5.5 million workers—brought the transport system to

This week, the Global Sumud Flotilla tried to deliver life-saving aid to Gaza. Instead, 461 people—including New Yorkers—have been detained by the Israeli military. They must be freed at once. And the deliberate starvation of Palestinians must end now.
Earlier this week I joined colleagues in urging @SecRubio to protect the Global Sumud Flotilla. Now my constituent, Zuleyka Morales Rivera, a U.S. veteran, has been abducted with other Americans bringing aid to Gaza. The State Department must act to protect all captives. They

Today Italy is on a massive general strike in solidarity with the Global Sumud Flotilla and Gaza. Reports of 100,000 people in the streets of Bologna alone.
Splende il Sole su Bologna e su 100.000 persone in piazza per la Palestina e le vite di tutti noi. Viva lo sciopero generale.
