I'm working on some figures for a book to illustrate the foundation of quantitative genetics (as confirmed by GWAS a century later). Mendel showed discrete inheritance in peas (left figure, 1860s). Fisher showed that many such Mendelian effects yield continuous traits (right figure, 1918).

Jonathan Anomaly responds in a long comment to my post criticizing his writing on eugenics and that of his company Herasight. He argues against several specific points and I encourage reading it in full. open.substack.com/pub/theinfin...

I drafted a letter to the editor, please help me out by DMing, commenting, emailing feedback if you are an expert on colliderbias, id obviosuly ad you as a author, Ideally we submit within 24-48 hrs, draft: zenodo.org/records/1800... (click download if the pdf doesnt preview on zenodo)

Last week, our new paper on indirect assortative mating was published.🍾 Let’s take a closer look at what this means, why it matters, and what we found (🧵/32): www.nature.com/articles/s41...

Within Anomaly’s defense of eugenics, one passage in his book especially alarmed me. It implies that his advocacy for “free reproductive choice” applies only when people choose to 'enhance' — since once an “enhanced” majority exists, those who refuse may face coercion or exclusion from reproduction.

Huh I wonder if there were any other global events happening in in 2008. Guess we’ll never know.

I wrote about the bizarre case of Herasight, the embryo selection company going all in on eugenics.

So happy to have co-authored this piece about IQ and education with my great colleague, the cognitive scientist and education expert Daniel Willingham @dtwuva.bsky.social. Our goal is to take intelligence seriously without lapsing into essentialism.

💼 💔 Academia’s toxic love language is playing “hard to get” 🧪 💓 Science is the beautiful pursuit of building knowledge I wrote an essay for Nature Human Behaviour on treating academia as “just a job” www.nature.com/articles/s41... What ideas would you add? 💡 #HigherEd #PhDLife #DiversityInSTEM

I wrote about missing heritability, "missing environmentality," and why I still think twin studies are interesting and valuable: kathrynpaigeharden.substack.com/p/twins-are-...

First time on Bsky and first big announcement! I am excited to announce that our new study explaining the missing heritability of many phenotypes using WGS data from ~347,000 UK Biobank participants has just been published in @Nature. Our manuscript is here: www.nature.com/articles/s41....

Blog post: A Missing Heritability Update. Three legs and other problems. I follow up on the recent excellent post on the subject by @sashagusevposts.bsky.social. ericturkheimer.substack.com/p/missing-he...

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵

“You see, the endless renovation of the Stuttgart train station is a symbol of our late-capitalist condition: the project is always ‘in progress,’ yet nothing ever progresses. The construction site itself becomes the true destination.”

Pleitropy (a set of known variants influencing the target 'positive' trait yet also potentially influencing another unknown -perhaps negative- outcome is already concern by itself (even if you don't care about the ethics and exacerbeting existing inequalities part of it which obviously you should)

With sequencing of Hitler's DNA making headlines, time for a reminder: analysing a polygenic score from a dead historically-significant figure won't give new insights into that person's behaviour. In a brief paper last year, we used Beethoven's genome to directly illustrate the fallacies involved.🧪👇

Unregulated and privatized polygenic embryo selection is a profound ethical threat. It turns reproduction into a commodity, reinforces social inequality, and normalizes genetic essentialism. Thank you, @arnovanhootegem.bsky.social & @gaiaghirardi.bsky.social for this powerful piece!

This paper clearly articulates what is, in my opinion, one of the major ethical problems with polygenic embryo testing companies--that they are *companies* that sell health as a private commodity. from @gaiaghirardi.bsky.social & @arnovanhootegem.bsky.social www.fertstert.org/news-do/embr...

With Paige Harden @kph3k.bsky.social we consider the greatness and bigotry of James Watson. Watson was not just a great scientist who turned out to be a bigot in his personal life. His bigotry was rooted in misunderstanding of the very science he created. Free link when I get one.

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.

Totally agree with the diagnosis, not sure about the suggestion of the two track system. it might create weird selection and sorting. cepr.org/voxeu/column... we should change the reward and publication system.
