Researchers are often advised to "reveal the person behind the science" in #scicomm to appear more approachable and trustworthy to their audiences. But does this really work? 🤔 In this short piece for Current Opinion in Psych, I review the recent literature... 👇 1/3

Really excited to see this work out! In her *first* dissertation chapter, Anna combined NLP and semantic network analysis to examine #moralization of populist rhetoric in the multiparty system of the Netherlands. Follow-up studies are currently on their way 🚀
My first publication :) in Social Media + Society with @fhopp.bsky.social, Michael Hameleers & @lindabos.bsky.social: “Moral Foundations of Populist Communication.” We found populists lean more on Care/Authority plus they shift moral tone across platforms more than mainstreamers.

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.

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.

Now, a new preprint using real-world data, careful experimentation, & computational modeling shows how curiosity modulates exploration. Way to go Jason!
