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.

🎓 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.

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.

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.

🚨 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

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?
