@briannosek.bsky.social I'm disappointed you didn't use this opportunity for a good April Fools joke, as in "everything replicates!!!". Arina K. Bones would have done that. Just saying.

New preprint out today (osf.io/preprints/ps...). We tested whether AI agents are actually infiltrating online surveys. Spoiler alert: they aren't Thread 🧵 [1/9]

Apparently we just need to replicate the damn study after all.

🧵1/ Our first meta-science paper (with 350+ coauthors) is published today in Nature. It presents one of the largest-ever reproducibility projects in economics & political science. Here’s what we found 👇

SCORE, a collaboration of 865 researchers, is now released as three papers in Nature, six preprints, and a lot of data (cos.io/score/). SCORE examined repeatability of findings from the social-behavioral sciences and tested whether human and automated methods could predict replicability.

Hey friends, my new paper was just published in JAMA Psychiatry. I draw on biological species classification to sketch a new framework for psychiatric nosology. Brief summary follows below. Full text link: jamanetwork.com/journals/jam... 🧪 #PsychSciSky #MentalHealth

Current NIH leadership want you to think they are using rigorous, consistent & scientific processes to screen studies to align them with agency priorities. But the process that they have put down on paper is a sham. It’s important to know NIH is not following its own guidance. Here’s why: 🧵1/

The problem cannot be reduced to the for-profit nature of scholarly publishers. In domains where there is real competition, like groceries, cars, or TVs, the free market delivers products that constantly get better, and cheaper. www.experimental-history.com/p/the-one-sc...

This is consistent with earlier psychometric work that suggests 5-7 is the best response scale options, but good to see that the finding holds up in contemporary research. Also, good to see that labeling scales whether anchored or not has little impact on findings. academic.oup.com/ijpor/articl...

This is the swamp in which we work. To pretend that these men are exceptional mistakes the deep misogyny & racism built into American higher ed.

Take a load off your minds everyone, it was regular old misogyny the whole time

Recent work has shown how vulnerable online survey research is to LLMs. Motivated by this, we examined our online Posner cueing data from Prolific. It's concerning. We now must carefully consider when (or whether?) online behavioral data can be trusted. see our comment: www.pnas.org/doi/10.1073/...

How the processes of recuperation vitiate apparent methodological advances in medical research, from meta-analysis to Mendelian randomization

Babbage, 1830, discussing the problem that scientists selectively report findings that they want to be true. Confirmation bias is a strong human tendency. This is why we need to design science in a way that prevents conformation bias from leading us away from the truth.

This article raises the larger point that it’s not just Individual decisions or moral failings that the Epstein files reveal. It’s a culture and clique that was self-reinforcing and enabling.

New paper, on a worrying trend in meta-science: the practice of anonymising datasets on, e.g., published articles. We argue that this is at odds with norms established in research synthesis, explore arguments for anonymisation, provide counterpoints, and demonstrate implications and epistemic costs.

New blog post about the age-period-cohort identification problem! In which, for the first time ever, I ask "What's the mechanism?" and also suggest that sometimes you may actually *not* be interested in causal inference. www.the100.ci/2026/02/13/o...

Happy birthday to one of my favourite haters, Charles Darwin

A meta-analysis on reducing discrimination finds: 1) passive interventions, such as short-term education or bias reminders, are ineffective 2) targeting behavior directly to inhibit bias (eg making individuals accountable or changing social norms) is helpful psycnet.apa.org/doiLanding?d...

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

Very happy that our new paper is out in Collabra: Psychology! 😀 Across three studies, we failed to replicate social class-based differences in conformity, which raises further questions about key assumptions of the social cognitive theory of social class.
