New pre-print!

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.

🚨 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.

Marvin Stecker @marvins.bsky.social · Aug 19

New publication, out in Political Analysis:

There is an increasing array of tools to measure facets of morality in political language. But while they ostensibly measure the same concept, do they actually?

I and @fhopp.bsky.social set out to see what happens.

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...

A semantic map of the situations described across all posts. The most frequently occurring situations pertained to family (21%), the office (8.4%), and weddings (4.2%).

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 📕

@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😎)

In a new study led by @delaneypeterson.bsky.social , we show how loneliness correlates with support for the populist radical right. Short summary and paper link in the thread below.

Delaney Peterson @delaneypeterson.bsky.social · Jan 22

Does loneliness correlate with support for the populist radical right? In the Netherlands, yes-lonelier individuals were more likely to support the PRR across 15 years of data (2008-2023), with effect sizes comparable to health correlates of loneliness. (1/9)

Loneliness is positively associated with populist radical right support

The mental and physical health consequences of loneliness are well documented. However, loneliness's socio-political ramifications have been largely u…
