Psychologist/author deconstructing behavioral/psychiatric genetic research and theories. Author of "Schizophrenia and Genetics: The End of An Illusion" (2023).
My question is this: If Jordan Lasker is outing himself as the name behind @cremieuxrecueil, why not describe the interview as asking about Jordan Lasker's "biggest concerns...," not "cremieuxrecueil's"? (Turns out his biggest concerns are "low fertility rates" and "China.")
I debunked the criminal adoption studies cited by Cremieux (J. Lasker) in a 2004 book chapter linked in my recent Substack post on the continuing "genetics of criminal and anti-social behavior" swindle. jayjoseph22.substack.com/p/genetic-st... jayjoseph.net/wp-content/u...
The Dutch government once gave medals to people who perpetrated aggression and violence in its colonial wars in Indonesia. The powerful reward “aggression” when it serves their interests, and blame it on faulty genes when it doesn’t. jayjoseph22.substack.com/p/genetic-st...
He was following the eugenic genocide playbook initiated by Francis Galton, and continued by psychologist Raymond Cattell in his 1972 book "Beyondism." He called for "phasing out" genetically "moribund cultures." The Am Psychological Association tried to give Cattell a "Lifetime Achievement Award."
I see that Google AI found my recently published description of the views of German "racial hygienist" H. W. Siemens. Siemens invented the "classical twin method" in 1924, which compares the behavioral resemblance of identical (MZ) vs. fraternal (DZ) twin pairs. journals.sagepub.com/doi/10.1177/...
In her new book, K. P. Harden discusses whether criminals are "born that way." The answer is a definitive No, as I showed in a 2001 publication and in my 2004 book, "The Gene Illusion." The main points still stand. jayjoseph.net/wp-content/u...
N. Cofnas wants to bring the IQ "hereditarian revolution" to Brussels, the "capital of Europe." The EU and NATO are headquartered in Brussels and are supporting the ethnic cleansing and genocide of non-white peoples. Seems like the "revolution" had already taken hold there.
Regime following the eugenics of F. Galton and followers such as psychologist R. Cattell in his 1973 book "Beyondism." The APA tried to give Cattell a 1997 "Lifetime Achievement Award," despite his having called for "phasing out" allegedly "moribund cultures." www.insidehighered.com/news/2009/03...
I can get back with more later. For now, here is a 1942 IQ test used by doctors in Germany to support the "clinical execution" of an 11-year-old German boy. From the 1994 edited book, "Cleansing the Fatherland" (G. Aly et al.).
World turned upside down: 1) Jews protesting genocide are "anti-Semites"; 2) U.S. citizens trying to stop ethnic cleansing are "terrorists"; and 3) "The Mismeasure of Man" is "an example of pseudoscience about race and IQ," and (presumably) Murray's "The Bell Curve" isn't.
Both peddle junk science in the service of far-right political agendas. For example, "The Bell Curve." osf.io/preprints/ps... www.madinamerica.com/2024/03/bad-...
Researchers who conducted 20 years of psychiatric and schizophrenia candidate gene studies never seemed to be embarrassed that these studies crashed and burned. One wonders how researchers making current claims about GWAS/PRS/CNV will react when these studies inevitably crash and burn.
Extreme skepticism aside, if psychiatry only learned to "objectively spot mental illness" in 2026, wouldn't that call into question all psychiatric research conducted prior to 2026? jayjoseph22.substack.com/p/the-110-ye...
100 years ago, eugenicists and others were sure that pellagra was a genetic disease, and not a disease of poverty, as it actually was.
IQ hereditarians are in shambles right now. The mean IQ correlation of reared-apart fraternal twins (DZAs) does not differ significantly from that of identical twins reared apart (MZAs). Conclusion: 0% IQ heritability (no genetic influences detected). jayjoseph22.substack.com/p/iq-heredit...
Interesting passage from a 1976 chapter by Minn. Study of Twins Reared Apart leader T. Bouchard. Here, Bouchard recognized that being raised in a “less than-favorable” environment – as opposed to a favorable one – could lower a person’s expected IQ score by 24 points! www.amazon.com/Human-behavi...
Whether it was Arthur Jenson on a typewriter in 1970 or @cremieuxrecueil on a laptop in 2023, the claim that Cyril Burt's "twin data" are valid and that twins in the earlier studies were "reared apart" is a form of scientific deception. See: www.madinamerica.com/2020/02/expl...
"Twins reared apart" studies falsely assume that the MZ-apart (MZA) IQ correlation is caused solely by genetic factors. In addition to being born at the same "Flynn effect" starting points, these 15 NON-genetic influences create MZA IQ and behavioral similarity (there are many more).
The abstract (author summary) of the 1990 Minnesota Study of Twins Reared Apart IQ study, published in Science Magazine, was quite unclear. Amazingly, it made it past the editor and peer reviewers, who apparently didn't question it.
How the 1990 Minnesota "reared-apart" IQ study found 70% IQ heritability (h2). The researchers hid their rDZA IQ results and bypassed Step 2 to avoid a 0% h2 result. Then, they claimed 70% IQ h2 based on the false assumption that rMZA is caused only by genetic factors (Step 3B).
Raven's Progressive Matrices is (supposedly) a "culture-fair" IQ test. The Minnesota twin study results (2007) show no statistically significant difference between MZA and DZA Raven means. Conclusion: The Minnesota result is 0% Raven IQ heritability. freeassociations.org.uk/FA_New/OJS/i...
Largely unknown. In the very famous 1990 "Minnesota Study of Twins Reared Apart" Science Magazine IQ study, the authors concluded that MZ-apart (MZA) twin psychological variance is mostly due to environmental influences. (They went on to count these environmental influences as genetic influences.)
This table shows the results of the very famous 1990 Minnesota Study of Twins Reared Apart Science Magazine IQ study. The 1990 DZ-apart (DZA) control group IQ correlations remain unpublished to this day. Why is that? freeassociations.org.uk/FA_New/OJS/i...
Cremieux blocked me two years ago when he had no answer to my debunking of "twins reared apart" studies. Now I'm a "crank" who doesn't know the origins of Mx software (as if that mattered). In my 2023 reply to Bouchard, I commented on the Mx (non) issue. freeassociations.org.uk/FA_New/OJS/i...
Any honest HBD race scientists out there? No one gets "canceled" for saying "IQ is above 0% heritable." That's Psychology 101. Claims in favor of genetic ethnic differences in IQ are another matter. HBDers knowingly conflate within- and between-group IQ genetic claims to hoodwink their audience.
A fascinating aspect of social media is that someone who blocked you years ago, and continues to block, can talk about something you supposedly "told" him about IQ prediction ("prediction" = correlation, not cause).
In an ironic historical twist, the criminal behavior of two German men may have been influenced by "syndromes" associated with each other's names.
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.
