It’s not the method that makes you causal it’s the assumptions

PsyPost did a piece on our recent study on assortative mating. Check out the full paper here: www.nature.com/articles/s41...

Major study reshapes our understanding of assortative mating and its generational impact

A large-scale study has found that people tend to pair based on shared social environments, not simply educational attainment. Published in Nature Communications, the research challenges key assumptions about assortative mating and how advantage is passed from parents to children.

Our fragmentation paper is now finally out! I put some of the dumb quips that didn't make the cut in the alt texts.
journals.sagepub.com/doi/10.1177/...

A fragmented field. If we conceive of the constructs and concepts studied in behavioral science as a map, we would find that it is highly fragmented and directions are hard to come by. Scientists can hardly stand on each others' shoulders if they cannot manage to meet on common ground.

Fragmentation has worsened, not decreased, as the field has grown. Partly, this happens because we have too many reverse Columbuses, who, in search of prestige, set out to find a new continent, but just end up renaming India. But partly, we face a real, solvable search problem when trying to connect our fuzzy constructs and flexible measures.

Most measures are used only once. To be clear, we do not want to prevent or reduce refinements of existing constructs and measures. Revisions, translations, and other refinements can contribute to a more coherent, organized literature and improve measurement. We are most concerned with the measures conceived with limited planning and released into the literature without much commitment or much of a life expectancy. In ontologies, these are sometimes referred to as “orphan nodes.”

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

🚨 New preprint out!
We reconstructed parental haplotypes in >440k individuals (UK & Estonian biobanks) to estimate assortative mating directly in the parental generation.
This reveals intensified assortment in recent generations.

I tried making a figure explaining how the sum of variances law can be understood as the diagonal of a bivariate normal, and how a correlation between the two antecedent variables — such as under assortative mating — will result in greater variance and more cases above a threshold.

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.

We have a new paper out, led by the great @hfsunde.bsky.social! We find that the correlation between parental income and offspring mental disorders may be partly causal in adolescence (phenotypic transmission), but that it is largely explained by passive genetic transmission in adulthood.

Hans Fredrik Sunde @hfsunde.bsky.social · Aug 4

Our new paper is out today! 🎉 In it, we use administrative register data to document how psychiatric disorders are strongly linked to parental income, from childhood far into adulthood. Furthermore, we attempt to separate causation and selection using kinship-based models.

A must-read piece by @sashagusevposts.bsky.social

I'll be That Guy™ and point out that this is why highly distributed pedigrees are used in evolution and animal breeding in nonexperimental settings. Sibs alone (esp. twins) give bad estimates. Good to see human gen getting on board.

Sasha writes about our new study (led by bluesky-less Nikolai Eftedal) where we show how simple genetic models don't adequately fit correlations between multiple types of relatives. The mismatch between observed and expected correlations are interesting, which are explained well in his blog post:

Nice confirmation of a commonly believed theory of why people in the Nordics generally speak English so well compared to central and southern Europe.
