Siblings affect each other in multiple different ways. How does having a same-sex sibling affect voting behavior? New paper in @electoralstudies.bsky.social !

The #ESSGN2026 conference is starting today! So many emotions mixing together for this conference that is very close to my heart. Happy and anxious that it's back in Bologna!

Thank you @rafaelahlskog.bsky.social and @aysuo.bsky.social for having me and for the opportunity to discuss our work! Check out the podcast in the quoted tweet below, and check out the paper we discussed here: www.nature.com/articles/s41...

@dr-appie.bsky.social is so awesome that me and @aysuo.bsky.social could not not have him back on the podcast. We talk in depth about his @nathumbehav.nature.com paper "Socioeconomic status is a social construct with heritable components and genetic consequences". Great conversation!

Seyla Benhabib, is the 2026 this year’s recipient of the Johan Skytte Prize in Political Science! Read more here: www.skytteprize.com/prize-laurea...

There was a lot of laughter during this conversation and a few secret confessions... But we also had some great discussions about musicality, genetics, Beethoven and public outreach, mental health, and music genres... Thank you @rafaelahlskog.bsky.social and @aysuo.bsky.social for having me! 🎶

omg it's laura wesseldijk, I love laura wesseldijk!

There appears to be an unusually large overlap between social science genetics and metal fandom. Had so much fun having this conversation with @aysuo.bsky.social and Laura Wesseldijk!

⚠️ This BGA has turned out to be exceptionally popular with unprecedented numbers of submissions and people wanting to attend. We are now holding a waiting list for non-speakers (this includes symposia Chairs and Discussants) who have not yet registered.

Just a reminder - deadline for this position coming up in less than two weeks!

I committed a podcast!

Bunch of cool personality related stuff in this episode!

For decades, Aadam Jacobs recorded live music shows. His collection of over 10,000 shows since 1984 features Nirvana, R.E.M., The Pixies, Björk, Depeche Mode, The Cure, and so many more — and they're now available on the Internet Archive for free. [kottke.org]

Good news are rare, cherish them.

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!

Check out this French popular science article on partner similarity and assortative mating, featuring yours truly:

Me and @aysuo.bsky.social went to Norway to talk to @perlinedemange.bsky.social. Some really cool stuff about the relationship between genetics of cognitive vs non-cognitive skills and mental health disorders here!

💼 Three postdoc positions: Genomics and life paths (Uppsala, Amsterdam and Oslo) bga.org/content.aspx...

Do a postdoc in Social Science Genetics at @uio.no! You will be part of a postdoc team in Uppsala and Amsterdam funded by @vetenskapsradet.bsky.social Please share! www.jobbnorge.no/en/available...

We're hiring! Are you a social scientist with experience working with genetic data? Join us as a postdoc and work on gene-environment interplay - with amazing data - in a collaborative project between Uppsala, Oslo and Amsterdam!

Me & @aysuo.bsky.social are hiring a postdoc to study gene–environment interplay in health & social inequalities 🧬 You'll analyze genomic data as part of a collaboration with Uppsala & Oslo at @amsterdamumc.bsky.social (NL) werkenbij.amsterdamumc.org/en/vacatures... Please RT for karma points ♥️

I made a tiny tool for quickly sharing small datasets (< ~1000 rows) without uploading any data to a server. 🔗 ziptbl.com It compresses the data into the link itself, so there’s no account, hosting, or storage layer involved. Here's Florence Nightingale's famous 📊 data: ziptbl.com#d=eNpdlE-LGz...

In a low stakes, artificial factorial experiment employers do not discriminate against immigrants. But when it is about actually hiring people, employers do prefer applicants with German-sounding names in the same experimental choice set.

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 🎧!

Me and @aysuo.bsky.social went to Oslo a couple of weeks ago. This conversation with @hfsunde.bsky.social was really, really exciting!

1. How do citizens interpret genetic explanations for socioeconomic inequality? This question is frequently raised in debates about the implications of social science genetics, but has so far been neglected as a research topic. >

Interested in using polygenic scores (PGS) in social science or health research? We are running a 2-day intensive short course @stats_UCL with @timtmorris.bsky.social (20–21 April 2026): tinyurl.com/5n6hwyxy. Ideal for all quantitative researcher across Social and Health Sciences! Get started!

Yo #polisky, you don't want to miss this one :)

The deadline has been extended till the end of this week, hurry! :)

What can sugar rationing during and after WW2 teach us about human health? Surprising findings from Stephanie von Hinke and others!

Really enjoying the new #ESSGN podcast by @aysuo.bsky.social and @rafaelahlskog.bsky.social. Really good entertainment and a great explainer for all things related to social science genetics. Check it out: essgn.org/podcast/.

Me and @aysuo.bsky.social went to Berlin to talk to @laraffington.bsky.social about all things epigenetics. Some really cool stuff here!

Paper on statistical power necessary for interaction effects doi.org/10.1177/2515...

ESSGN doctoral candidate Asya Bülbül reflects on what political scientists can learn from integrating genetics.

New paper out! Working with geospatial data is cool.

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Me and @aysuo.bsky.social talk to @sjoerdalten.bsky.social about economics and genetics. And we get some book recommendations. Neat!

Wouldn't miss this if I were you!

📢🧬 Call for Papers — 5th ESSGN Conference 📍 Bologna, May 21–22, 2026 I’ll be co-organising the 5th ESSGN conference in Bologna together with Nicola Barban, Stephanie von Hinke, Paul Hufe, and Niels Rietveld @essgn.bsky.social 📄 Submit here: forms.gle/fmVDUrQqQYju... 🗓 Deadline: 1 March 2026

Me and @aysuo.bsky.social did a thing. Give it a listen!

One more year coming up - have not updated on this.

My department is hiring a PhD student in Political Science for an open position! I really enjoy working here and recommend all who are interested in a PhD in Political Science to apply. Deadline is 6 February 2026! su.varbi.com/en/what:job/...

Less than a month before my debut book "What We Inherit" gets released! You can place pre-orders now: press.princeton.edu/books/hardco... Lucky to have gotten to collaborate (and argue) with Sam Trejo for the last 5+ years on this.

✨Winter School #IT19 ✨ Sarting the Nineteenth Winter School on #Inequality and #SocialWelfare Theory (#IT19) 3 days, 85 participants, 25 talks, 3 lab sessions, 40 posters/presentations, a lot to learn about! @cesifo.org @liser.lu Uni Verona @cy-univ.bsky.social @lseinequalities.bsky.social

I probably won't have time to make a video out of this. But the materials are available online, and should be pretty self-explanatory. Hope this is useful to some people. privefl.github.io/statgen-cour...

Apply to be my colleague!

I feel incredibly lucky and honored to have been selected as one of the recipients of this very generous grant from the Knut and Alice Wallenberg Foundation. Looking forward to working hard over the coming years - lots of exciting research in social science genetics coming!

So happy to have received a new, generous grant (500k EUR) from @vetenskapsradet.bsky.social to continue exploring the causes and consequences of voluntary segregation among lesbians, gays and bisexuals in Sweden. This time with a dream team of @rafaelahlskog.bsky.social & @turnbulldugarte.com

A fun way to start the wknd: We have received the reviews of ”Rallied by thy neighbor: how minority spatial concentration increases voter turnout." […] I am delighted to conditionally accept your article for publication in The Journal of Politics. @rafaelahlskog.bsky.social @turnbulldugarte.com
