I wrote about the bizarre case of Herasight, the embryo selection company going all in on eugenics.

Twins Are So Much More Interesting Than Heritability Estimates On starting places, "missing environmentality," and the Waddington landscape of life

Polygenic and developmental profiles of autism differ by age at diagnosis - Nature A study of several longitudinal birth cohorts and cross-sectional cohorts finds only moderate overlap in genetic variants between autism that is diagnosed earlier and that diagnosed later, so they may represent aetiologically different conditions.

This was a fantastic collaboration with lots of people including @hilarycmartin.bsky.social @jakobgrove.bsky.social, Experts by Experience, and several others who I can't seem to find on this app.

A deep and thought-provoking lecture that is definitely worth watching all the way through.

Let’s not “memory hole” the Flynn Effect, whereby objective cognitive measures show large mean cohort trends that are not plausibly reflective of any sort of general aspect of intelligence, but the individual correlates are largely invariant across generations.

But what is messy? What is late? Still subject to frame of reference.

Perhaps not peer comparison but shifting frame-of-reference, concept of normative or ideal, use of language… what @michelnivard.bsky.social likens to a vowel shift. Not necessarily the case, but important to consider, rather than trusting mean trends in self-report as veridical without question.

The interpretation is that the charter schools increase conscientiousness, self control, & grit... but also make students more self-critical with respect to those skills (perhaps they are cured of a Dunning-Krueger effect), such that self reports of those skills go down while the skills improve. 5/5

One of the coolest examples of this is a natural experiment (lottery study) for oversubscribed charter schools (doi.org/10.3102/0162...). The charter schools increased student achievement but reduced self-reported noncognitive skills that are known to relate to achievement. 4/

they may be misleading when comparing across cultures, cohorts, or possibly developmental periods due to different ways that people interpret the questions and use the likert scales, reference bias, etc... 3/

Unfortunately, "objective" observation- and task-based methods for measuring personality have much weaker construct validity and criterion validity. While self-reports are a great way to measure individual differences in personality among people matched on culture and context... 2/

A few related conversations have been converging on the question of when various trends and observations with respect to personality are genuine. This is a complex issue without a simple answer... A key issue is that personality is best measured using self- or informant ratings... 1/

The twin/family studies were not clear whether it was dominance vs. epistasis vs. some other sort of nonadditivity. Dominance was just the easiest to model. We can now estimate dominance SNP h2 but can’t obtain an estimate of epistatic SNP h2. Assimilation/contrast effects may also be at play.

To close the loop on this, this is what we wrote in the review (originally posted on the other platform).

Humbled to receive the BGA's early career award ☺️ Thank you to my brilliant team #MPRGBiosocial, the @maxplanck.de for investing in early career researchers, @mpib-berlin.bsky.social for the excellent environment, and my many mentors incl @kph3k.bsky.social @tuckerdrob.bsky.social #ScienceTeamSport

Omg 😂. Well played @michelnivard.bsky.social

O, right I promissed JUICE! Not everyone believes in this work, one of the "haters" was very early... In fact @ent3c.bsky.social practically leant over this papers' crib and said: "well that's not going to be a looker."... Someone just as petty as me, but far more organized, kept the receipts 👇

You will have seen this post by @tedmond.bsky.social‬ on our new GWAS of Personality. He says you should read the paper (you should), I want to write a thread to entice you. Because social media has shredded your attention as it has mine, I promise there is JUICE & BEEF in this thread!

Probably the most important paper in personality psych this decade just dropped. 👀 Interesting genetic correlations between other traits (the #1 reason for GWASs on social traits IMO), and evidence of weak but non-zero assortative mating on personality.

🔥🔥🔥 2 years of our lives right there (extremely proud of everyone, I’ll write a thread later)

Extremely excited to share the first effort of the Revived Genomics of Personality Consortium: A highly-powered, comprehensive GWAS of the Big Five personality traits in 1.14 million participants from 46 cohorts. www.biorxiv.org/content/10.1...
