🧵One of the most encouraging trends in academia over the last decade is the semi-spontaneous emergence of a massive interdisciplinary network committed to confronting scientific racism in all of its disgusting forms and applications

Jon Phillips @jowiph.bsky.social · Nov 6

I decided to go ahead and make a starter pack of historians, scientists, and others who work on scientific racism. If you’d like to be added to the pack (or removed from it), let me know.

Only tangentially related, but a certain Russian-American geneticist once received a passport randomly assigning him the middle initial J (he had no middle name). On a trip to Brazil, an official wouldn't let him in with just J on the paperwork, so he became Theodosius Juan Dobzhansky

There was a hitch, at the very end. Well, a very minor hitch was that when my passport came from Washington, -- of course,
getting a foreign passport in wartine was not so easy -- I have sudenly acquire? a second initial. Just how it happened, I have not the faintest tea, but the passport came for somebody caller The posius J. Dobzhansky, So ever since, I was "J."

Q: ft's really H, len't 1t? Or none at all?
Dobzhansky: No -- tbere 1a no socond initial, of course, at all.
But naturally It would have been nothing short of foolish to send a passport obtained with such difficulty, after presumably investigations and so on, in order to remove a J. All my passports since have had a J. I am presumably legally a J. now.
*: Did you make up a name to go with 1t?
Dobzhansky: Yes. At one time, also in Brazil, when a not very Intelligent Brazilian official demanded that I have a second name, as 1t should be, after several attempta to explain to him tbat I baa no socond name, I finally decided, why not Juan?
*: Then you have a Brazilian second name.
Dobzhansky: So I have a Brazilian second name.

There are reports that the *entire* office of special education at the US Dept of Education has been cut. These hardworking folks ensure kids with disabilities get equal access to a quality education.

America’s children deserve better than this.

The 16-year-old who shot two students in a Colorado high school on the same day Charlie Kirk was killed was a virulent white supremacist and antisemite www.denverpost.com/2025/09/11/e...

‘Radicalized’ Evergreen High School shooter appeared to hold antisemitic, violent views in online accounts

Social media accounts that appear to be connected to the 16-year-old shooter are littered with references to mass shootings and antisemitic views, The Denver Post found.

Too bad the GOP effectively criminalized studying how information moves online and news orgs laid off and demonized all the reporters who covered the burgeoning online accelerationist performative death cults. All of that work was somehow "censorship" that needed to be stopped. Now we're here.

Important details from this story:

1) Yet another news-break by student journalists (this time @theharvardcrimson.bsky.social) www.thecrimson.com/article/2025...

2) Harvard saying "see you in court," not "let's make a deal."

3) Per Garber, WH/MAGA leaked news of a "deal." NYT then ran with it.

Headline from Harvard Crimson: "Harvard President Garber Tells Faculty He Is Not Considering a $500 Million Deal With Trump."

Text of story: Harvard prez Garber says report of a deal "was apparently leaked to the press by White House officials." NYT ran with it as a story.

It is depressing, but all too predictable, how swiftly we’ve gone from the Social Science Genetic Association Consortium offering reassurances about the uses of behavioural polygenic scores to one of their lead authors marketing embryo selection for IQ

Text from an FAQ in Okbay et al 20222:
https://www.nature.com/articles/s41588-022-01016-z
a similar same statement is made in an FAQ in 2025: https://www.biorxiv.org/content/10.1101/2025.05.14.653986v1.supplementary-material
Text reads:
"The results of SSGAC studies have sometimes been used by online platforms, including some companies, to predict individual outcomes. We recognize that returning individual genomic “results” can be a fun way to engage people in research and other projects and to feed or stoke their interest in genomics. But it is important that participants/users understand that these individual results are not meaningful predictions and should be regarded essentially as entertainment. Failure to make this point clear risks sowing confusion and undermining trust in genetics research"

A fourth employee of Heliospect is an active quantitative racism researcher, publishing with the usual race science crew on bogus Jewish polygenic score comparisons (work that was immediately and summarily rebutted: trejo.scholar.princeton.edu/sites/g/file...).

A third employee (and senior author on the research whitepaper) somehow accidentally ended up posting anti-immigrant slogans in a private chat with an Austrian far-right activist (aka neo-Nazi) Martin Sellner:

A second employee (and the first author of the Herasight research whitepaper) was a member of a Telegram group for the pro-eugenics online publication Aporia. Aporia also frequently publishes on the topic of white racial solidarity:

A final point about trust. Herasight has apparently partnered with Heliospect Genomics, founded by self-described eugenicist Jonathan Anomaly (a member of both companies). Anomaly and Heliospect were profiled last year by Hope Not Hate:

A few thoughts on Herasight, the new embryo selection company. First, their whitepaper (drive.google.com/file/d/1EpFi...) implies that competitors like Nucleus have been marketing and selling grossly erroneous risk estimates. This is shocking if true! 🧵
