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.

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

Really? Systematic racism is built into IQ tests, which are designed to produce ethnic but not gender differences. Murray and Pinker assume ethnic differences are influenced by genetics, when there is no scientifically valid evidence supporting even WITHIN-group "heritability" osf.io/preprints/ps...

It can’t be stressed enough that, false genetic between-group difference claims aside, The Bell Curve presented no scientifically valid evidence in support of genetic influences on within-group IQ score differences.
In 2018, Charles Murray challenged me to a bet: "We will understand IQ genetically—I think most of the picture will have been filled in by 2025—there will still be blanks—but we’ll know basically what’s going on." It's now 2025, and I claim a win. I write about it in The Atlantic.
Your Genes Are Simply Not Enough to Explain How Smart You Are
Seven years ago, I took a bet with Charles Murray about whether we’d basically understand the genetics of intelligence by now.

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.

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.

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."

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.

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.
