One of the few times I'm reminded that Norway is *technically* not in the European Union

Could be constant (or decreasing) assortment, but that the assorted traits have become more heritable over time (leading to greater genotypic correlation between partners)

First, it is important to note that “assortative mating” is not synonymous with “partner similarity”. Instead, assortment is only one of several processes that can lead to partner similarity, the others being convergence, stratification, and inbreeding.

In Germany, there are two kinds of children. If your child is of the second kind (less of a temperament I guess), afterschool care is cheaper.

I also wrote a more detailed thread when I posted the preprint last year. Check it out here if you are interested: bsky.app/profile/hfsu...
We have a new preprint!📰Here, we describe the association between parental income and psychiatric disorders from childhood and into adulthood, and use children of twins and siblings to differentiate social selection from social causation (1/n)🧵 Link: doi.org/10.1101/2024...
