People believe that a lack of morality -- a core component of antagonism -- has less potential for change than other traits. www.sciencedirect.com/science/arti...

New paper by my PhD student @semihaktepe.bsky.social now published 🚀 "Revisiting the effect of discrepant perceptual fluency on truth judgments" tinyurl.com/2eepue5y --> Two experiments & a meta-analysis indicate that high visual contrast does not lead to higher truth judgments.

Very excited to team up with @tomhardwicke.bsky.social and talk about error prevention in publications! I'll talk a bit about developments in statcheck - a spellchecker for statistics - and Tom will share insights as head of the STAR (reproducibility) team at Psych Science.

🚨Summer School Alert!🚨 Join the FREE Open Research Summer School (in-person or online) to learn about good quality science. I'll be talking about a practical four-step robustness check to assess and improve quality of findings. Check out the full program for many more fantastic speakers!

A question for #psychology researchers - sth my students ask me often: what if I can't find previous literature that supports my hypotheses? Perhaps they haven't looked widely enough, but let's assume there is really no previous evidence or theory to inform the hypotheses. What is ur take? RT pls.

The Metascience 2025 pre-conference symposia are kicking off on Monday! These webinars are free to attend, open to all, and spread across multiple time zones. Make your choices and sign up here: metascience.info/virtual-symp...

@psych.peercommunityin.org is open for submissions! (Nice to see our @yutoozaki.bsky.social et al. @manyvoices.bsky.social work cited as an example of the flexible publishing options you can get with @peercommunityin.bsky.social !)

Great news for psychology!

Peer-reviewed preprints... this is the way! Great to see PCI expanding into new domains. #takethepowerback

PCI Psych is open for business! Send us your papers!

“If you have no interest in publishing in journals, but see value in having your work peer reviewed, we are here for you.” Now that’s speaking my language 🙏

Folks, it's time to submit your papers to PCI Psychology. Here is our invitation to you, taken from our editorial osf.io/preprints/ps...

Check our new—dare I say provocative—paper in Motivation Science, led by @eddiehj.bsky.social: "Valid Replications Require Valid Methods: Recommendations for Best Methodological Practices With Lab Experiments" psycnet.apa.org/fulltext/202...

A group of research-integrity experts have launched the Collection of Open Science Integrity Guides (COSIG), a toolkit for budding sleuths that outlines how to spot suspicious scientific papers.

Excited to welcome @ephemeralidea.bsky.social to King’s Open Research Summer School on Mon 21st July. She’ll be sharing new reflections since Big Little Lies, a standout in the growing movement to detect and challenge questionable research practices misconduct. 🔗 Register: tinyurl.com/j7y9962r

@jamesheathers.bsky.social has won $900k in philanthropic funding to establish The Medical Evidence Project, which will find flawed medical research that costs lives. www.nature.com/articles/d41...

Science-integrity project will root out bad medical papers ‘and tell everyone’ Thrilled to announce this new $900,000 project headed by @jamesheathers.bsky.social

A huge development for normalization and support of the scientific sleuth community as an important component of a healthy, high integrity research system.

My guide on GRIM and GRIMMER will be added to COSIG soon. Very cool set of open resources, take a look or get involved!

The quarto-preprint extension v0.16 (github.com/mvuorre/quar...) now enables full-width content in two-column #quartopub #typst documents (and more!; via github.com/christopherk...). Hope this makes Quarto a bit more useful for writing well-typeset reproducible #rstats manuscripts 💙

‘Anyone can do this’: Sleuths publish a toolkit for post-publication review The Collection of Open Science Integrity Guides (COSIG) aims to make “post-publication peer review” more accessible Project headed by @reeserichardson.bsky.social @cosig.net retractionwatch.com/2025/06/04/c...

Can you imagine that in 2010 if you worked in psychology you could not publish a replication study that yielded a null result if your life depended on it? You might think: So how did they identify Type 1 errors in the literature? They didn't! >>>

It was not impossible, but it was not easy either. One variable, for example: Joy-Gaba and Nosek (2010) had (if memory serves) >50X the original sample size. Schmidt and Nosek (2010) had >1000x the original sample size. The increased precision was not necessarily appreciated by reviewers.

1/ 🧠 New research out now! Why do people think some psychological phenomena (like falling in love) are harder to explain scientifically than others (like reading a map)? Turns out it depends on the type of explanation people think about!

Are you passionate about #scicomm & psychology in the context of #Sustainability? We are looking for a PhD-candidate (75%; 4 yrs) for the Hub Science project "Psychology of Transformation" at Leuphana University Lüneburg! www.leuphana.de/universitaet...

A reminder that at University College Dublin we are hosting @lakens.bsky.social from Eindhoven University of Technology. On Wed 4th of June, 12-13, C006 Health Sciences, Prof. Lakens will give a talk on open science and will discuss why it is worth improving our research practices. All welcome!

If you work in psychology in a research area without Registered Reports, you will see that the main hypotheses in papers are almost always supported. If your peers publish Registered Reports, you will also have access to null results, which should be very common. doi.org/10.1177/2515...

New work led and orchestrated by @sandrajgeiger.bsky.social🌍 We replicated pluralistic ignorance in climate beliefs in 11 underrepresented countries. Public-consensus intervention? Not really effective. We also looked at cultural differences using secondary data. journals.sagepub.com/doi/10.1177/...

Across 3 studies, we find that valuing future lives equally—regardless of their distance in time—predicts stronger interest in long-term oriented, high-impact careers. Preprint here: osf.io/preprints/ps... @stysyropoulos.bsky.social @amormino.bsky.social @lianeleeyoung.bsky.social
