Over the last month I saw that human editors are now stripped of control. I could no longer stop the system from auto-inviting "reviewers" with zero relevant expertise. Even worse - the AI began actively revoking the invitations I manually sent out to actual, qualified experts.

Nature recently published massive studies on the credibility of social science. We — the Norwegian co-authors on the robustness-paper, Gerit Pfuhl, @oysteinhernaes.bsky.social, @maxkorbmacher.bsky.social, and me — wrote an opinion piece about it (in Norwegian): www.forskersonen.no/forskning-kr...

Hva kjennetegner god vitenskap?

KRONIKK: Troverdig forskning er ikke forskning uten usikkerhet. Det er forskning som viser oss usikkerheten i stedet for å skjule den.

SCORE, a collaboration of 865 researchers, is now released as three papers in Nature, six preprints, and a lot of data (cos.io/score/). SCORE examined repeatability of findings from the social-behavioral sciences and tested whether human and automated methods could predict replicability.

This is cool work on a methodological level, but I also really like how “assortative mating on liability to divorce” is essentially a six-word relationship drama.

Can we estimate assortative mating for outcomes shared by partners? Yes we can! In a new paper together with @philippdierker.bsky.social, I find that individuals with similar liabilities to divorce are more likely to get married in the first place!

I was on a podcast! I had great fun talking about my favorite social science genetics topic (partner similarity!) with @aysuo.bsky.social and @rafaelahlskog.bsky.social. If you want to learn more about assortative mating and why it is so interesting, give it a listen 🎧!

What's up with partner choice and genetics? In this episode of Born and Raised, @hfsunde.bsky.social talks all things assortative mating!

There seem to be a whole (older) cohort of eminent social psychologists who essentially do not understand the concept of sampling error, and I wonder to what extent that lack of understanding was an adaptive trait for a career.

This very interesting project has finally been published. Congratulations! They find stronger genetic associations with place of residence than place of birth for many traits, showing that population stratification also involves active rGE. Read @iakuznetsov.bsky.social's thread here:

Remember the famous UKB migration paper? We found that internal migration also shapes population structure in Estonia. Key patterns replicate within families. www.cell.com/iscience/ful...

Welcome to my 2025 scientific publications wrapped! It's been a good year for behavioral genetics, with exciting studies on the relationship between our DNA and socio-economic outcomes, sexual behavior, personality, intelligence, and psychiatric disorders 🧬 See thread below 👇🏽

Det er det samme i Norge. Finansieringsmodellen belønner studentens progresjon (studiepoeng, grader) og straffer de som stryker studenter. Studentenes rettsikkerhet er svært sterk, og innbyr til klaging m.v. Universitetene bør befris fra dette, og gjøres mer uavhengige!

Since we are doing university education takes: By far the most time consuming task is failing students. You are also published for it by getting less money. This creates an incentive system that is not ideal.

Cross-country analyses of EA PGI associations are a crucial step towards an increased understanding of how genetic influences occur in conjunction with societal structures - but also of the inevitable challenges that come with doing so. See this new study out in Molecular Psychiatry! ⬇️
