🚨 Excited to share our new paper in @NatureHumBehav! In a cross-societal online behavioural experiment with 3,371 participants in 13 societies, we found that perceived societal honour norms predict both greater competition and greater cooperation. 🔗 https://t.co/dJZtPOiacb 1/9

Long thread about our Stage 2 submission with more insights: https://t.co/lN2xRTseTc
Can we please also stop already with all the supposed MTurk data quality crisis? Learn how to use the platform, use @cloudresearch, employ checks like we do, & you'll get data quality comparable and possibly better than student samples and Prolific. If we can do it, anyone can.

It's absolutely amazing the a PCIRR Stage 2 community endorsed manuscript automatically is accepted in a journal like Royal Society Open Science with no additional peer review needed. Go PCIRR friendly journals! https://t.co/KgnqDV0BmP Why aren't there more journals joining?

In prediction polls I ran on TwitterX back in 2022, 73.3% of 30 votes thought it would successfully replicate. Poll: https://t.co/5YwevLbh27 See that thread to check how that compares to the other predictions.
(Twitter prediction markets #13) Will it replicate? Thaler, 1999 | 17 problems from review Mental accounting matters JBDM | 4700 citations https://t.co/YNMOnq3sxF (Amy)

We conducted a replication & extensions of Thaler (1999), the seminal =review article = of mental accounting covering many studies in behavioral economics. A very complex replication project. Conclusion: Mostly successful, support for 11 of 17 scenarios, 3 mixed, 3 no support.

Thrilled to announce a new paper out this weekend in @CognitionJourn. Moral psychologists almost always use self-report scales to study moral judgment. But there's a problem: the meaning of these scales is inherently relative. A 2 min demo (and a short thread): 1/7

I was so sorry I missed SIPS2025 in Budapest (long story, regional conflicts), but glad I had a chance to come by, & meet the local group that does wonderful open-science work with purpose and impact. Had lots of interesting exchanges, and learned a lot. And Budapest is gorgeous.
