2015: the CLPM is misspecified, it doesn't account for stable traits, use the RI-CLPM! 2025: the RI-CLPM is misspecified, it doesn't account for linear decay over time, use the ARTS! (But actually, given how stable everything is, maybe just don't estimate cross-lagged models in adults)

Submissions are now open for 22nd European Conference on Personality (Edinburgh, 2026); deadline 7/12/25. Keynote speakers and pre-conference workshops have also been confirmed. www.ecp22edinburgh.org/submission

Report: You To Be Fired For Reading This Headline About Charlie Kirk

The largest study on late life virginity, based on >400k individuals, out now in @pnas.org Open access link: pnas.org/doi/10.1073/... Shoutout to shared first author @laurawesseldijk.bsky.social ❤️ Thread below 👇🏽

I wrote a little note on awards for diversity and science: mwkraus.medium.com/a-note-on-aw...

Proud to share our new @nber working paper on how genetics shape the intergenerational transmission of socioeconomic status in the Netherlands. 🧵(1/8) www.nber.org/papers/w34208

Looking for recs on a novel (any genre) where, when you read it, you kept thinking "dang this author has a LOT of fun ideas"

Simon Wood, the GOAT of generalized additive models & creator of the mgcv #rstats package, has an Annual Review of Statistics essay on GAMs, available open access #statssky #mlsky www.annualreviews.org/content/jour...

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!

New paper out at the Journal of Psychopathology and Clinical Science! We examined unconditional & event-related changes in pathological vs normal-range personality using 4 metrics to compare their developmental links, how these vary with life events, and whether unique effects emerge across metrics

this whole "we have to be super private about our salaries" nonsense does nothing but protect the wealthy and privileged by helping hide income and wealth disparities. It's also, fucking annoying.

I'm looking for a PhD student to do some trailblazing at the frontier of personality genomics and lifespan gene-environment transactions (start Fall 2026)! If you want to work with me: psychology.msu.edu/graduatestud... (PS @drmeltemyucel.bsky.social is taking a student too, in moral psych/dev!)

📣 New paper published in @natcomms.nature.com‬, where we explored sex differences in local genetic correlations, local heritabilities, and magnitude of effect sizes in quantitative traits. link: rdcu.be/ezuZd 1/7

It's so refreshing to hear Chance the Rapper back and in form. I didn't realize how much I missed him. New album is a comfy 7/10.

2 bits of data from new Economist/YouGov poll..... 13% support for cutting research funding to universities. 24% among Republicans. Polling on this continues to be catastrophic for the Rs, suggests Dems should be learning far harder into standing up for science and our universities. 1/

An updated preprint of our Borderline Personality Disorder GWAS is now online: www.medrxiv.org/content/10.1...

I wrote about my recent experiences taking care of my 3-year-old, Sheila Heti's "Motherhood", and the discourse around polygenic embryo selection: kathrynpaigeharden.substack.com/p/openness-t...

Are there any really good papers/posts for teaching nesting in structural equation models? My vibes advice of "well if the difference is mostly parameter constraints it's probably nested, and if the difference is in latent variables it isn't, can I just look at your syntax?" is ... not so helpful.

New pre-print online: Imputing parental genotypes through Mendelian Imputation: Ethical and Legal Considerations osf.io/preprints/ps...

Check us out!! So proud of our team.

New preprint! Ever heard that personality doesn't change? Do you believe that? (you shouldn't) Using data from an online survey (n = 887) & eight longitudinal datasets (n = 166,971), we compared perceived vs. actual lifespan changes in personality and 20+ individual differences (1/8) osf.io/ytmxp

Newly accepted in PSPB! We examined whether Asian and Black Americans perceived one another through a zero-sum lens. Inspired by the SCOTUS affirmative action decisions, I wanted to know if Asians thought they were losing to Black people and how this mindset affects coalition osf.io/preprints/ps...

I’m looking for a postdoctoral scholar to join me in the Self & Society Laboratory at UC Riverside! Sharing would be much appreciated! aprecruit.ucr.edu/JPF02104

Another thing to mention for people who don't live in LA. Most of LA is very chill and peaceful right now. There's a huge Pride fest going on, countless farmer's markets, tourists walking around, families at the parks, people walking their dogs. It's a big place.

It's very odd that Google doesn't offer a button that allows you to turn off their AI "results."

Out now in @nathumbehav.nature.com: Cuts to NIH funding will impact the economy and employment nationwide. We visualize these losses and advocate for a theory-driven approach to communicating local, self-relevant impact. w/ @joshuasweitz.bsky.social + SCIMaP team: www.nature.com/articles/s41...

PGI Repository v2.0 preprint out! A 🧵 on the main results and updates @robel-alemu.bsky.social @paturley.bsky.social @alextisyoung.bsky.social

New lab preprint, from @abbycassario.bsky.social's furiously typing fingers to your eyes

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...

Super brief video intro-ing the alpha version(!!) of an free studyguide/book in sequence models and deeplearning in/for genomics.

For my multilevel modeling students, I created a tutorial sharing all the main functions I use for data cleaning in R. It took me maaaany years to figure out my cleaning workflow, so I wanted to share it with y'all in case I can save anyone else time :-) sites.google.com/view/gabriel...

Working over at the University of Michigan library today for a change of pace. Where the anti-genocide protest was last year is now a construction zone (they're replacing not-very-worn cobblestones) with an extremely large fence perimeter supervised by three guards. Safety is paramount on campus!

Some really interesting contrasts in our new "assumption-free heritability" preprint: papers.ssrn.com/sol3/papers....

Thirty-eight of 43 experts cut last month from the boards that review the science and research that happens in laboratories at the National Institutes of Health are female, Black or Hispanic, according to an analysis by the chairs of a dozen of the boards.

if you're a PhD student or postdoc working at the interface of personality psychology and CS/ML (construed broadly on both sides), and are interested in doing a full-time, remote, 3 - 6 month internship/residency at MidJourney, please DM me some kind of resume or CV-like thing

Harvard redid its whole homepage to push back against the administration’s demands. I mean, this is just a website but I think it’s kind of a great PR move: www.harvard.edu

Its been hard to track science chatter given the state of the world depands our attentino, i have some bluesky science feeds/starter packs and tools than help me 🧵 👇1/4

A tricky thing about modern society is that no one has any idea when they don’t die. Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

An important point getting overlooked: When NIH cancels "diversity" grants (e.g., diversity supplements, Fs, Ks, etc), they aren't canceling the grants based on *what* the grant studies. They're cancelling them based on *who* is doing the research. And that disallowed "who" is anyone not white.

BREAKING: We're suing the National Institutes of Health over their politically-motivated purge of research grants. This is an unlawful attack on scientific progress that puts lives at risk.

Gave a talk recently on race and affirmative action, and the organization recorded it. Check it out! tinyurl.com/gohtalk

Completely batshit that Harvard has *removed* Cemal Kafadar as head of its Center for Middle Eastern Studies & so shitty to malign one of the great scholars of Ottoman history as antisemitic because the CMES dared to offer programming on ITS AREA OF FOCUS www.thecrimson.com/article/2025...

Now I understand why Frenkel-Brunswick wrote The Authoritarian Personality -- so many people preemptively submitting to fascism is really forcing me to double-take

🚨 A new episode is out! Lisanne de Moor spoke with incoming editor-in-chief Matthias Ziegler and outgoing editor-in-chief @renemottus.bsky.social about the change in editorship at the European Journal of Personality and how they reflect on and look ahead at their time in the role of Editor-in-Chief.
