Closing out my year with a journal editor shocker 🧵 Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...

Early Christmas present! For the last couple of years, I have been helping to update this textbook for a new edition. I joined a great team that had written the original book, and together we thoroughly revised it and updated it with new research and examples. My copies arrived just the other day!

A thread on a new preprint: "Addressing Demand Artifacts In Psychological Research (And Beyond)".

Thrilled to share this new preprint, co-authored with @peterlush.bsky.social and Chloé Fournier Bernard! We offer a broad and structured discussion of leading methods developed in the past >60 years to tackle demand artifacts in psychological research and beyond. doi.org/10.31234/osf...

In a large, preregistered study (see preprint), we compared InteroMap to emBODY. Overall, InteroMap demonstrated superior construct validity and usability www.researchgate.net/publication/...

Very excited to introduce InteroMap, a new bodily mapping tool designed to measure how we subjectively experience our bodily sensations, what we call interoceptive phenomenology 🧵👇

New publication. Congrats to the whole team, and especially @paulbertin.bsky.social who led this effort. Thanks also to the editor (Nicolas Sommet) and reviewers, who desserve credit for improving our paper.

In this new research, we found that truth beliefs can be successfully conditioned: Statements - true and false - are rated as more true after their pairing with positive than negative pictures. This effect bridges research on evaluative conditioning and misinformation. osf.io/preprints/ps...

This overturns familiar assumptions of perceivers as “cognitive misers” and calls for rethinking how we conceptualize automatic evaluations.

Even with skin tone as a group marker and explicit instructions to form group-based impressions, people relied more on the actual characteristics of the individual they encountered.

In this research, we found that individuating information dominates social group information when forming impressions about members of newly learned social groups. This dominance was observed both on self-reports *and* more automatic measures *despite* conditions favoring group-level impressions.

“52% of all autocratization episodes become U-Turns, which increases to 73% when focusing on the last 30 years. The vast majority of U-Turns (90%) lead to restored or even improved levels of democracy” V-Dem data

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!

Remarkable thread by Micah Allen here 👇🏼

It is amazing that most organizations (businesses, media, NGOs, political parties) that worried about the threat of the far right for decades have spent no time or energy to thinking how to operate in a far right world. They just continue to do the same and are surprised by a different outcome.

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...

Very pleased to be featured in the August Editorial for Nature Mental Health! The stomach’s turn: elucidating the gut–brain axis www.nature.com/articles/s44...

📢Excited to share our paper, "Studying unconscious processing: Contention and consensus", published in BBS. The paper is the result of a collaborative effort of 32 leading researchers in the field, from 10 different countries🌏 Check out the full ms👇 www.cambridge.org/core/journal...

I find it amusing that ChatGPT can write predictive processing theories that are about as plausible as many published versions. I guess they really are that predictable…

After more than 7 years working on it, I’ve just submitted the manuscript for Discovering Statistics using R second edition. Tonnes more work on website/package and so on, but getting to this stage is monumental psychologically. It’s the book I feared I’d never finish.

New research shows that simply changing how a reaction vessel is positioned on a magnetic stirrer can significantly change a reaction's speed and product quality, influencing the reproducibility of results. #ChemSky #ScienceSky #EduSky

We may all have thought trade and import tariffs gaf drifted out of the spotlight, but it’s definitely back on the radar. A good time to check out @timharford’s Seven truths about trade—still true, even under 50% tariffs for the EU: buff.ly/6IBO0fH

Economic pressure is a major threat to press freedom. @rsf.org is clear: "The economic indicator on the RSF World Press Freedom Index now stands at an unprecedented, critical low" The global state of #pressfreedom is classified as a 'difficult'. For the first time #WPFD2025 rsf.org/en/rsf-world...

We also recruited “observers” who were matched with the original “actor” participants, shown their choices, and asked to predict the actors’ choice process. Actors were more accurate than observers, suggesting that their accuracy came from some kind of first-person introspection.

Are we “strangers to ourselves”? Classic theories say people have limited insight into how they decide. Our new paper at @natcomms.nature.com challenges this view. With @rcarl.bsky.social sky.social, @hedykober.bsky.social y.social, and @mjcrockett.bsky.social www.nature.com/articles/s41... 🧵

My paper on concerns about replicability, theorizing, relevance, generalizability, and methodology across 2 crises is now in press at the International Review of Social Psychology. After revisions it was 17500 words, so it is split in 2 parts: osf.io/dtvs7_v2 and osf.io/g6kja_v1

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they? One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers. 1/n

Fifty years from now, there will be a moment of silence to remember some of this.

So good. 🤡 @brendanvduke.bsky.social

Several countries have recently managed to stop and even reverse the erosion of their democratic institutions. In each case, people resisted growing authoritarianism. This shows that when democracy deteriorates, its fate is not sealed, and democratic institutions can be reclaimed.

74% of Europeans say their country benefits from EU membership—the highest support recorded in 42 years. With peace and security top of mind. 66% want a greater role for Europe in protecting them against global crisis & security risks. We hear you. And we’re ready to deliver. → europa.eu/!3VByd4

Today I lost an NIH grant training clinicians to do research about intimate partner violence with perinatal women. More women are murdered in the perinatal period than die of obstetric complications. I didn't just lose a grant. We lost an entire cohort of people building careers to prevent that.

Psych. Science just published a paper showing that the "warm glow" of donations can reduce depressive symptoms (d = [0.19, 0.46]). Most impressively, "micro" donations (one Chinese cent, or $0.0014) appear sufficient to trigger these large effects. Big if true? Let's dive in.

Today we published a Correspondence and Author reply related to on an article we published last year, 'Self-reports are better measurement instruments than implicit measures' Correspondence: go.nature.com/4brCRzX Author reply: go.nature.com/3DilAN0

In a recent @natrevpsych.bsky.social paper, we argued that self-reports are superior to implicit measures for most research questions. A Commentary raised concerns about our conclusion. Our Reply addresses these concerns and explains why we stand by our conclusion www.nature.com/articles/s44...

In this new preprint, we argue that the role of demand artifacts in evaluative conditioning research can't be readily dismissed. We highlight methodological challenges by discussing three recent articles that addressed that question: dx.doi.org/10.31219/osf...
