Race as a Bundle of Sticks: Designs that Estimate Effects of Seemingly Immutable Characteristics
Although understanding the role of race, ethnicity, and identity is central to political science, methodological debates persist about whether it is possible to estimate the effect of something immuta...

Watch out many-analyst/many-labs. There's a new kid on the block. Seems "adversarial collaboration" is the hip new thing to do in 2026.
🚨 Now out in Psych Science 🚨
We report an adversarial collaboration (with @donandrewmoore.bsky.social) testing whether overconfidence is genuinely a trait
The paper was led by Jabin Binnendyk & Sophia Li (who is fantastic and on the job market!) Free copy here: journals.sagepub.com/eprint/7JIYS...

If you care about confounding, causal inference, and sensitivity analyses this is *not* for you; you are thinking of "E-value". Different thing. Different workshop.

What are ppl's thoughts on either of these two?

More research like this on other psychometric scales is needed (although the IAT should just be abandoned regardless).
Researchers and practitioners should know the precision of their tools. If someone is 1pt over a cutoff how reliable is this for classification and treatment?

How often do you see in an intro section the authors making a clear distinction bw causal papers they cite and observational ones? All seem to be magically causal. 🤔
in psych, whole subfields have decided to simply skirt the issue, so the causal inference happens in the introduction of the next paper that cites the "totally-not-causal-I-swear" paper and of course absolutely interprets it causally 🥲

While adoption of open science/research hadn't been ubiquitous, I think many researchers just realised the limitations of old approaches and said "ok, I need to do slightly better if I want to not fool myself with my studies". This is having a clear benefit.
