NEW from me in @pnas.org on the risks of data sharing with qualitative research: "Today, confidentiality risks are amplified by social media, surveillance, and AI tools, which make ample data about people publicly available, thus making deidentification less effective" www.pnas.org/doi/10.1073/...

New working paper with @robertboehm.bsky.social: it is an early version likely needing significant revision, so feedback is very much appreciated. We review multi-level games: a family of economic games that capture tensions within and between groups simultaneously. (1/5) doi.org/10.31234/osf...

New paper in press in EHS We looked at how group membership shapes social norms (reputation assignments in IR). 💡Second-order information influenced the reputation of cooperators (not defectors) more within the group boundary than across it www.cambridge.org/core/journal...

@makitotakei.bsky.social, Chanki Moon & @hirotakaimada.bsky.social test if target publics see audience costs. US survey (N=1,404): people infer domestic punishment for backing down; credibility is similar for democracies and autocracies. Read more here: journals.sagepub.com/doi/10.1177/...

New paper led by @makitotakei.bsky.social! We found experimental evidence for one of the key theoretical tenets of audience cost theory - those in the challenged country understand that the challenger’s leader would face a punishment for backing down.

🚨New paper led by Lei Fan, with Florian van Leeuwen, @hirotakaimada.bsky.social, and @joshtybur.bsky.social, out in Cognition & Emotion: 🔗 doi.org/10.1080/0269... In two preregistered studies from Japan 🇯🇵 , we find that anger relates to confrontation while disgust to gossip and social exclusion.

Can people be led to defend the opposite of their religious beliefs? A new study by Prof. Ryan McKay and colleagues shows they can, shifting later attitudes too. The paradigm holds real promise for illuminating big questions in the field. Open access: doi.org/10.1080/2153...

I had an amazing time in Vienna☀️ Thank you Qinyu (@qinyuxiao.bsky.social) very much for hosting me!

It was great to host Hiro @hirotakaimada.bsky.social for a few days in Vienna to discuss research on in-group favouritism, indirect reciprocity, and intergenerational cooperation!

New paper in @commspsychol.nature.com 🚨 We found future ingroup favoritism and outgroup derogation in both minimal and national group contexts: people made more and less sustainable choices when future beneficiaries were ingroup and outgroup members, respectively. www.nature.com/articles/s44...

Had a great time visiting London Interdisciplinary School. I’m very excited for potential future collaborations🧠💡

Thanks to everybody who chimed in! I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist. So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>
