This week, Born and Raised went to talk to @perlinedemange.bsky.social about cognitive and non-cognitive skills, and their shared genetics with education and psychopathology. Also: christmas elves! Don't miss.

Cognitive, Non-Cognitive, and the Genetics In Between: Perline Demange on Skills, Schooling, and Psychopathology | Born and Raised
What do we mean when we talk about "non-cognitive skills," and what does genetics tell us about them? In this episode, our hosts visited Perline Demange to talk about the genetic architecture of cogni...

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. >

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. With the fantastic @gaiaghirardi.bsky.social

🧵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 doi.org/10.1080/0140...

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.

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.
