Second thesis article now out in Political Behavior! Using PGIs for ~10 000 full-pair fraternal twins in STR, combined with rich, geo-coded register data, I highlight the compensatory interaction between genetics and family + neighbourhood factors, with regards to voting. 🗳️

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! ⬇️

Maybe the 1st study to show gene(PGI)–environment interaction in political participation? Using unique Swedish data, Oskar finds that high-SES & politically active families and early life neighbourhoods can weaken genetic influences on voting.

There’s a new kid in town!
Companies are now selling IVF and embryo selection based on genetic testing for traits related to health and even intelligence.
We outline methodological and ethical concerns, and warn against risks for social inequality.

Embryo selection based on polygenic prediction risks reinforcing social inequality
The rise of companies offering embryo selection based on genetic testing has triggered heated debate about ethical acceptability, as well as the accuracy and scientific validity of these techniques. W...

🧵1/ Are primaries bad for political diversity? Conventional wisdom says yes—but our article in @wepsocial.bsky.social shows that candidate selection modes are not necessarily a bottleneck for representation, at least when it comes to demand. 🗳️👥 @sandrahkansson.bsky.social

Looking forward to next week's #ESSGN IV! Happy to be presenting two projects: 1) the effects of genetic explanations for socioeconomic differences on citizens' perceptions of inequality, and 2) collaborative work on the (changing) link between cognitive skills and income in two Nordic countries.

🧵 What kind of POPE do AMERICANS want?📸
Before the Conclave, @sophiemainz.bsky.social and I asked 1,500 U.S. adults to choose among hypothetical papal candidates.
Results: Americans prefer a liberal and *non-political* Pope. The latter might be challenging for Leo XIV.

Not that I don't find this very fascinating, and while I have probably been guilty of doing something similar, I do think we need to be more precise, even in an abstract, than to describe our independent variable as "genetic propensities towards art"

This remarkable tendency of 4o not executing an entire request, but doing the first few sections, and then telling me to do the rest myself. Is this the AI equivalent of shrinkflation?

This is Winston Churchill visiting the White House during World War II.
Funny how he isn’t wearing a suit either. Almost like he was a wartime leader defending his country from being slaughtered and wiped out by an authoritarian aggressor.
