The 110-Year “Schizophrenia Genetic Research” Train Wreck
The “genetics of schizophrenia” area of research—which began as a eugenics program—is currently in disaster mode and awaits its endpoint.

I’ve shared these a few times on the other site, but since everything is new again, here’s a thread of extremist profiles on prominent scientific racists I wrote for @SPLC roughly 10 years ago:

The decades-old Danish schizophrenia adoption studies by Seymour Kety and colleagues 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.

I always try to keep scale in mind with political action. This is about 3% of Italy's population. A U.S. equivalent would be ~10 million people.

The causes of autism are in the news these days. In my 2006 book "The Missing Gene," I assessed the evidence that autism has a genetic basis. The evidence usually cited came from twin and DNA-based research. I concluded that the genetic evidence was weak. Chapters:

Good news. The key point is to differentiate true genetic diseases like Huntington's from major psychiatric conditions, which are not diseases and are not genetic. In psychiatry, there can be no gene therapy because there are no genes to therapize. Just "psychiatric yetis," using EF Torrey's term.

Phenomenal. In my 10 year update of A Brief History, I make the point that in the first edition, not one disease had been successfully treated using gene therapy. Today that number is at least 7.

True, which suggests that the behavioral sciences should take a hard and objective second look at twin studies and their underlying assumptions (EEA). Not to mention the Minnesota "read-apart" twin study, where the researchers hid their control group data to find above-zero IQ heritability.
jayjoseph22.bsky.social
The main study cited by race scientists in favor of “high IQ heritability” is the 1990 “Minnesota Study of Twins Reared Apart” Science Magazine IQ article. In that study, the researchers hid their control group data to avoid a within-group 0% IQ heritability conclusion. Classic p-hacking maneuver.

Psychiatric Genetics founder Ernst Rüdin co-wrote the 1934 book promoting and explaining the 1933 Nazi forced sterilization law. Rüdin showed doctors how to perform the procedure. The law was based on eugenic junk science, and about 6,000 people died as a direct result of the procedure.

This massively and openly p-hacked schizophrenia adoption study was published 50 years ago, and is still cited in most psychiatry textbooks. If p-hacking and relying on faulty assumptions are "highly heritable traits," this would explain most psychiatric genetic research "findings."

The Freedom Flotilla is once again setting sail: Dozens of boats from 44 countries are carrying aid, food, medicine, and doctors to Gaza, aiming to break through 18 years of Israeli siege.

Robert Plomin's 1998 adoption study of personality found no genetic influences (not quite what he concluded, as might be expected).

You might be interested in my 2001 article on the topic, which later became a chapter in my book, "The Gene Illusion." The article was published in 2001, but its main points remain valid.

Kety's Danish schizophrenia adoption study and Bouchard's Minn. "reared apart" twin IQ study are world famous. In both studies, no genetic influences vs. the control group were found. The first study's author changed the control group. The author of the second study hid the control group data.

NEW: In 40 cities across Australia, an estimated one million people have been on the streets calling for an end to the genocide in Gaza.

These were the scenes in Brisbane, Melbourne and Perth.

The U.S. government sends troops to cities allegedly to "fight crime." One reason is the regime's belief that criminal behavior is "in the genes." In this 2001 article, I showed that there is no valid evidence supporting this old belief. There still isn't.

Interesting article. If the NY Times approached behavioral and psychiatric genetic research publications with the same level of scrutiny, as opposed to its usual practice of reporting them as examples of solid science, both fields might collapse.

Patrick Sullivan is a leading psychiatric genetic researcher. Yet his website states,

"...specific genes that have a causal role in [schizophrenia] have yet to be identified."

50 years of failed searches for what EF Torrey called a "psychiatric yeti."

Despite a replication sample, like other psychiatric diagnoses, most likely these are non-causal chance or spurious associations. In addition, BPD is a controversial and vaguely defined condition of questionable reliability and validity. Such research does not help improve the human condition.
