Since search is dead, how soon do you think Google Scholar is headed for the Google Graveyard? I'm betting it's soon, and academia is NOT prepared

Google Scholar Is Doomed

Academia built entire careers on a free Google service with zero guarantees. What could go wrong?

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...

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.

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 mental disorders, compare education by ability, and run sibling-fixed effects. Check it out here: doi.org/10.1177/0956...

🎓 Educational attainment also independently predicted better mental health.
But the highest risk was for men who were low in both cognition and education.
This group faced the highest probability of adult psychiatric diagnoses.

Last week, our new paper on indirect assortative mating was published.🍾 Let’s take a closer look at what this means, why it matters, and what we found (🧵/32):

1/13 New preprint out! We developed methods to test a key assumption in family-based genetic studies: that siblings don’t genetically influence each other’s traits. Spoiler: mostly they don’t, but there’s a twist with ADHD ratings at age 3 👶

I will write a detailed thread next week. If something is confusing until then, I highly recommend the supplementary notes, where I go through the logic more slowly and in greater depth.

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.

Our paper on indirect assortative mating is now out in @natcomms.nature.com! 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.

Very grateful that I got to present at the ESSGN past Friday. In the study I presented, we looked at intergenerational transmission of education in a sample of the Norwegian population register. We used a Children-of-Twins model to look at GPA at age 16 and educational attainment in the parents.

New preprint!

We find no evidence that parental mental health influences children's academic achievement when comparing families in the Norwegian MoBa study.

🚨 Big question, big paper! Why does educational inequality run in families?
The parent-child education link (r = .31) is often seen as purely environmental.
From 569k kids, we decomposed it:
🧬 68% genetic
🏡 12% parental environment
👴 20% extended-family environment

Vi har et skrikende behov for kunnskap for å møte vår tids utfordringer, med fallende skoleprestasjoner og økt fravær.

Derfor er det avgjørende med et nasjonalt individdataregister fra skoler og barnehager, mener Camilla Stoltenberg, @martinflato.bsky.social, @torvik.bsky.social og Karin Monstad.

Hvorfor er det tilsynelatende umulig for folk å forstå at dersom statens råd skal ha legitimitet så må de være basert på forskning og fakta og ikke bare være noe som mest mulig er på linje med følelsene til ressurssterke bekymrede foreldre? Og at man kan gjøre ting uten at staten sier det?

Nasjonale skjermråd – nå!

Foreldre trenger tydelige råd om barn og skjermbruk, ikke mumlete anbefalinger som ingen oppfatter.

(9/10) Several reasons besides direct assortment can explain partner similarities. In this paper, we cannot determine which processes are most important. However, we can distinguish between these in future research.

Fartein Ask Torvik @torvik.bsky.social · Dec 3

(8/10) Could health similarities be by-products of partner choice based on education? To some extent—partner correlations in health were reduced by 30–40% after accounting for educational attainment in adulthood or school grades at age 16.

Fartein Ask Torvik @torvik.bsky.social · Dec 3

(7/10) Do mental health and education determine partner choice? Many studies assume so-called direct assortment. If direct assortment fully explains partner choice, it would be easy to predict correlations between siblings-in-law. But they are much more similar than expected under direct assortment.

Fartein Ask Torvik @torvik.bsky.social · Dec 3

(6/10) This means that children with a mental disorder are more likely to have another parent with a mental disorder or with low education. This matters for the distribution of both genetic and environmental risk factors among children.
