Here is my account of what happened to Scientific American before the latest meltdown, when the wokeness first began to rot this once great institution. michaelshermer.substack.com/…

The Fall of Scientific American Emmet Fraizer picks up the story where I left off a few years ago, as this once great national institution of publishing went full woke, and as always happens, wokness poisons everything. thenation.com/article/societ…

Did you know there’s such a thing as “queer anthropology”? Anthropologist @eweissunburied says her field has traded logic, falsifiability, and consistency for ideology. The goal is no longer to discover the past. It’s to mold it. In collaboration with @HeterodoxCentre

Scientists & science journalists decry the public's rejection of science, but are oblivious to the major cause: the perception, sometimes correct, that scientists are just another political faction. Among the guiltiest perpetrators are the recent editors of Scientific American, who turned this once-beloved treasure into a left-wing propaganda rag. This absolutely does not justify the Trump administration's unconstitutional meddling, but the new owners are right to restore it to its mission of explaining science to Americans.

🚨 NEW: For the @WSJ, @Hartz_PhD and I expose the ideological takeover of the American Psychological Association. The APA is facing the possible loss of its federal accreditation authority following allegations of widespread antisemitism. But while the APA's antisemitism problem is serious, it's only a symptom of a much deeper ideological rot. The organization has become so captured by radical left-wing political activism that its commitment to scientific objectivity competence is now in serious doubt. We examined the program for this year's major APA Division 39 conference, which drew nearly 800 attendees and held 90 panels over four days. By our count, roughly 70 of the 90 panels were overtly political, and always left-wing. Topics included abolishing the family, queer anarchist psychoanalysis, dismantling gender assessment guidelines, and white supremacy. One session even concluded with a drag show. There was at least some hope that the threat of losing federal accreditation might prompt some institutional soul-searching. It didn't. Instead, APA members just elected Candice Hargons as their next president. Her campaign identifies "systemic intersectional oppression" as the profession's "common enemy" and calls for rejecting the traditional scientific notions of objectivity. Psychologists wield enormous influence over vulnerable patients, and the people seeking treatment deserve the peace of mind knowing that the care they're receiving care is evidence based and not tainted radical politics. We believe most would agree that federal accreditation should actually mean something. If the APA cannot distinguish its scientific mission from its political activism, the Education Department should reconsider whether it deserves the government's endorsement as an authority over psychological training.

Reality and satire are indistinguishable: the president-elect of the American Psychological Association has a paper on “#hotgirlscience”. Read the abstract; it’s real. With this at center stage, imagine the biases, rotten assumptions and errors where no one’s looking

How many more such studies as this do we need before transitioning adolescents ends as one of the worst cases of medical malpractice in history? Abstract: Gender-referred adolescents showed significantly higher psychiatric morbidity than controls both before (45.7% vs. 15.0%) and ≥ 2 years after referral (61.7% vs. 14.6%). Those referred after 2010 had greater psychiatric needs than earlier cohorts, both before (47.9% vs. 15.3%) and ≥ 2 years after (61.3% vs. 14.2%) referral. Among adolescents who underwent medical gender reassignment, psychiatric morbidity increased markedly during follow-up—rising from 9.8% to 60.7% in feminising gender reassignment and from 21.6% to 54.5% in masculinising gender reassignment. After adjusting for prior psychiatric treatment, all gender-referred adolescents had similarly elevated risks of psychiatric morbidity, with hazard ratios approximately three times higher than female controls and five times higher than male controls. Conclusion Severe psychiatric morbidity is common among gender-referred adolescents and appears to be more prevalent in those referred after the recent surge in referrals. Psychiatric needs do not subside after medical gender reassignment. onlinelibrary.wiley.com/doi/…

The degeneration of Nature, Science, NEJM, and Scientific American into woke propaganda dispensers (and their refusal to publish normie, centrist, common-sense responses) is a scientific scandal.
Wokeness is corrupting science from within. Nature went woke years ago with their support of trans pseudoscience (sex is binary, not a spectrum) and now they think the death of Jason Arday sends a wake-up to us: yeah, stop lying.

I strongly disagree with the proposals in this thread. Rejecting papers because the author "lacks a publication record or credentials in the research area" is the worst form of gatekeeping. It violates the first Mertonian norm: universalism. And requiring "oral examinations" for arXiv authors is absurd.
Replying to @tdietterich
How should the scientific enterprise handle this? We could try to decide whether the author understands the work. E.g., if the author lacks a publication record or credentials in the research area, we could reject the submission. 3/

"I like to quote the founder and proprietor of Our World in Data, who said that the papers could have had the headline: “187,000 people escaped from extreme poverty yesterday, every day for the last 30 years.” But you never saw that headline, and as a result, a billion people escaped from extreme poverty. One of the most significant events in human history, and no one knows about it."

I've always thought that the campaign against "ultra-processed" foods was mindless. What the heck does that even mean: the more things you do to food, the less healthy it is? New RCTs and analyses confirm that the stigma is meaningless (it's calories, fiber, & other causes, not "ultraprocessing") and even harmful: it encourages RFKj's MAHA quackery. I suspect that food researchers are subject to class bias: food that poor people like and can afford must be unhealthy. vox.com/future-perfect/49404…

A remarkable moment in mathematics publishing: almost the entire editorial board of the Journal of Approximation Theory has resigned simultaneously, declaring that “the journal, as we knew it, has ceased to exist.”

A 10 min video on the great José FM Valls His work in collecting & characterising the wild species of peanut is extraordinary. It shows him in his environment, in the field, talking to people, explaining about the plants — Fantastic! Worth watching even if you don't speak Portuguese (link in reply)
