Our paper on indirect assortative mating is now out in @NatureComms! In it, we provide refined definitions of terms used to explain partner similarity, develop statistical models, and find evidence of surprisingly high social homogamy for education. Link:

Our new study is just out in Psychological Science! We study cognitive ability at age 18 and mental health 20 years later in 270k Norwegian men. We include different disorders, compare education by ability, and run sibling-fixed effects. Check it out here:

New paper just out! It includes: .- Assortative mating ✅ .- Nature-nurture of social outcomes ✅ .- "Things are complicated"-conclusion ✅ .- Summary statistics available for reanalysis! ✅ . Check @EivindY's thread for more:

I have written a detailed thread (31 posts!), but for that, you need to go to the other place!.

Results imply that partners are strongly assorting (r=.68) on education-associated trait(s) with large shared-environmental effects (i.e. Social Homogamy). Accounting for this in intergenerational models reveals previously hidden or underestimated environmental effects.

While we focus on health traits, we also report the partner correlation in GPA at age 16 (i.e., educational performance way before most partners met). This correlation is almost the same as years of education (.43 vs. 47), despite often being completed after partner formation.

New paper! We look at partner similarity *before partner formation*, across health traits and education. Correlations across psychiatric traits are ubiquitous, become larger in established couples, and are only partly explained by education. See Fartein's🧵for more:
