After 5 years of data collection, our WARN-D machine learning competition to forecast depression onset is now LIVE! We hope many of you will participate—we have incredibly rich data. If you share a single thing of my lab this year, please make it this competition. eiko-fried.com/warn-d-machi...

Do you want to work with me?:) Please spread the word! We are looking for talented Post-doc candidates for a 10-month Junior Fellowship at the Behavioral Science Center, hosted by the Corvinus Institute for Advanced Studies (CIAS). 1/6 www.the-bs-lab.com

This important meta-science article should not be hidden behind a paywall.

Join our Replicability Project: Health Behavior! We have 55 replication studies underway, our target is 65-70. We are only recruiting for secondary data replications--i.e., using existing data to test the original question. Here's a list of studies we think could be feasible. If interested...

The Impact of Financial Resources on Cognitive Performance: A Systematic Review and Meta-Analysis, from @peterszecsi.bsky.social, Pal Kolumban, Aikaterini Taka, and @szaszibarnabas.bsky.social doi.org/10.1525/coll...

Today's HotFresh recommended paper is: Szaszi, B., Goldstein, D. G., Soman, D., & Michie, S. (2025). Generalizability of choice architecture interventions. Nature Reviews Psychology, 4(8), 518–529. doi.org/10.1038/s441...

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

Thank you for sharing -- I was unaware of this framework for choosing among replication targets. I think I stand with the critics. Of course I'm left still not knowing how to choose among empirical estimands! Separately, this figure is amazing:

ReplicationResearch.org is now open for submissions! Submit replications and reproductions from many different fields, as well as conceptual contributions. With diamond OA, open and citable peer review reports, and reproducibility checks, we push the boundaries of open and fair publishing.

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

Read: www.researchgate.net/publication/... Thanks, Anna Dreber & economist team that made this a reality, & @PRASAC for taking lead. Main question: Can prediction markets and surveys accurately predict if classic social psychology & JDM findings will replicate in new data collections?

New 📰 Demand characteristics are a fundamental methodological concern in research with humans Yet little is known about the magnitude and consistency of these effects In a new paper, I, M. Wyatt, and @mcxfrank.bsky.social take stock of what we’ve learned via meta-analysis doi.org/10.1525/coll...

If you consume or produce research, I say that you must learn about the commercial publishing system. Start with @forrt.bsky.social's glossary (forrt.org/glossary/eng...), watch the Paywall Movie (www.youtube.com/watch?v=zAzT...) and learn about OA types. Think about who you want to do research for.

In @natrevpsychol.nature.com, Team Scientists @szaszibarnabas.bsky.social, @dggoldst.bsky.social & @dilipsoman.bsky.social and Susan Michie argue that improving how we study nudges—through better design, collaboration, and open science—can help us learn when and where they’re most effective.

Here's a quick blogpost about alternative publishing models. You can bring a horse to water, and indeed wave the bucket temptingly under its nose, but it is likely to gallop off elsewhere. deevybee.blogspot.com/2025/07/new-... @ec.europa.eu @wellcometrust.bsky.social

🧵 Can you predict whether behavioral interventions will work in new contexts? … probably not, right? In our new paper with @dggoldst.bsky.social @dilipsoman.bsky.social @susanmichie.bsky.social, we dive into how to better understand and improve generalizability. rdcu.be/ewD2z Summary👇

Day 2 of #SIPS2025 ended with a fabulous boat trip! I’ve been told that SIPSers took part in traditional Hungarian dances led by @martonkovacs.bsky.social and @szaszibarnabas.bsky.social . But what happened on the boat, stays on the boat. Tss!

HELP! 🙏 I’m looking for validated emotionally neutral texts (ideally pretested or normed) to use in a control condition. Participants will read the text and count letters. Any leads, references, or resources? 🙏

This is shocking behaviour by Wiley; the stated justification does not stand up. I will not be doing any peer review for Wiley journals in future.

PCI Psychology is here!! 🎉🥳 After over a year of hard work by so many people, we are thrilled to announce that we are open for submissions! Join us in making publishing more efficient, equitable, and open: psych.peercommunityin.org #PsychSciSky #scipub

A recently published meta-analysis in Nature Human Behaviour "found evidence supporting the efficacy of social comparison as a behaviour change technique in shaping behaviour in the desired direction". I was curious, so I re-analyzed the manuscript, but the funnel plots below say it all.

What is the future of Open Science? Join @annemscheel.bsky.social @nicholascoles.bsky.social @szaszibarnabas.bsky.social @aufdroeseler.bsky.social and @stephaniemlee.bsky.social for an exciting discussion during the Keynote Panel at the #SIPS2025 Online.

I was sent a paper to review that cites a book I did not write. As in, it cites a made up book with my name on it. Quick look in the references, and I quickly found several more non-existent papers. People. People. This is supposed to be science. What are we doing? This made my soul feel tired.

I recently pre-tested forty and used thirty "facts" like that for class exercise about preconceived notions. The one most of of my psych students bought was "Brain drain: A smartphone lying on the table reduces attention span." Alas: x.com/rubenarslan/...

EADM is now on BlueSky. We will post about JDM news, papers, and events (like spudm2025.imtlucca.it, see you there)

A new prologue episode! Who first made the claim that more than 50% of published findings might not be true? It was Neher, 1967! We read his full paper as preparation for next week, where we will critically discuss Ioannidis, 2005, repeating this claim. nulliusinverba.podbean.com/e/prologus-5...

Excited to kick off the #SPSP2025 Happiness & Well-Being Preconference today! 🎉✨ We’ve got an incredible lineup: the Global Happiness Megastudy 🌍, a taxonomy of positive mental health 🧠, The Global Flourishing Study 🌱, & Flourish Science 🤖 (a happiness AI coach!) Let’s go! #WellBeing 😃

Universities in the UK and US, facing declining government support, will not renew expensive deals with Elsevier and others. Scholars need to support low cost journals! See e.g. freejournals.org, which is looking for new board members.

The visa and ESTA of my two PhD students has been rejected so they cant come to #SPSP2025 with me. If you are there and want to talk about behsci interventions, generalizability, happiness, megastudies, contact me so I won’t feel so alone! Also, check out my talk about our Happines Megastudy!

Our new study was just published in Nature! In Michigan, we find a large and persistent racial excellence gap over time. Socio-economic status explains one-third of the racial disparity in top academic achievement while school factors only explain about 1/10th. www.nature.com/articles/s41...

People, just stop doing Frontiers special issues. Find a nice diamond open access journal, and self-publish and collaboratively peer review the set of papers you all want to write. Do not give Frontiers money. They add no value. If anything, they hurt your reputation. MDPI is of course even worse.

So, who is coming to #SIPS2025? Don't miss it! It will be the 10th SIPS, so we will come together to evaluate the reform and gather new momentum to improve science. Day 0: Sightseeing, hiking dinner: on a boat on the Danube Let others know that you are coming to Budapest so they can meet you!

I don’t like to give advice to PhDs, in part because I felt like I got tons of conflicting advice myself, but… … a PhD takes at least 4 years, a timeframe likely encompassing considerable AI gains. I would tell them to think in advance about what things it will change & how to use them in you favor
