Is there a need for domain-specificity when studying mental health (MH) and politics? In our study in the Netherlands, we find political mental health (PMH) is distinct from MH & has unique political correlates, from polarization to ideological extremism.

Our new paper in @nature.com, 5 years in the making, is out today.

🚨 Be aware of the tool pile for measuring moral foundations 🚨
In a new multiverse analysis led by @marvins.bsky.social , we report that existing moral foundation measurements (surprisingly?) fail to converge on multilingual party manifestos, with implications for substantial research questions.

Congrats Ale!

@t-1m.bsky.social doing an excellent job presenting our work on MoralNet at #CCN2025 where we explore the alignment between brains and machines during moral perception.

🧠❤️🤖⚖️ We had an inspiring and fun satellite event at #CCN2025 forging new research ideas at the intersection of emotion, morality, and brains. Excited for next steps!

I’m excited to share my first first-authored paper with @abitter.bsky.social in the Journal of Happiness Studies:

“The Emotional Climate of Academia: Exploring Social Media Data as an Indicator of Well‑Being.”

Wonderful news Josh, congratulations!

Thank you so much and for all the continuing support!

I am truly grateful and honored to receive the rising star award by the wonderful @icacsab.bsky.social A huge thank you to everyone for their support along this wonderful journey. Science is a team sport that would not be possible without you!

🚀 Very happy (and proud!) that rockstar @michelleschimmel.bsky.social received a top student paper for her MSc thesis, which I had the pleasure to supervise. Excited to see this work out soon!

Reddit’s AITA? board is a goldmine of data on how real people conceptualize and solve moral dilemmas. A study of posts on the board finds that the nature of the relationships between people in a dilemma is central to moral decision making. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

If you are interested in extracting moral values from text corpora, check out our latest resource, the extended Morality as Cooperation Dictionary (eMACD). Led by the brilliant @musamalik.bsky.social, we show that eMACD surpasses the (predictive) validity of previous moral foundations dictionaries 📕

I’m looking forward to my first #BookaScientist and interesting questions on #AI and #morality.

Are LLMs impartial moral judges? @sarahmlr.bsky.social doing an excellent job sharing our first results at #MoralMedia25, highlighting that LLMs rate moral violations from ingroup members less severely than the same actions committed by outgroup members.

Congrats Steve!

@curtispuryear.bsky.social a study of a decade of twitter posts shows and new measure of moralization shows that moralization has substantially increased over time (d = .45!). Driven by both self selection and within-user increase over time! #comppsych #spsp2025 (also stay tuned for this paper😎)

Language-like efficiency in whale communication Whale vocalizations follow efficiency rules seen in human language, revealing striking similarities in communication systems.

Do whales optimize their vocalizations for efficiency, just like human language? 🐋🎶 My latest study in
Science Advances (@science.org) suggests they do—following linguistic laws seen in human speech. 🧵 www.science.org/doi/10.1126/...

*Moral Stereotyping in Large Language Models*

We show that LLMs are inaccurate in estimating the moral values of diverse cultures: LLMs stereotype cultures in predictable ways.

Check out this amazing work on using computational modeling for exploring #curiosity in book selection!

We checked all boxes for a great research retreat!

✅ Exchanged interests and expertise
✅ Forged new collaborations
✅ Stayed in an old castle in the middle of nowhere :)

Thanks Bine! Let’s catch up soon :)

We have lift off! 🚀Super excited to be working with these brilliant researchers on integrating #sciencereception, #metascience, and #computation in #psychology.
