Come to work with me! I am looking for a PhD researcher (f/m/d) for a 4-year research project on the impact of negative emotions on the formation of conspiracy beliefs - considering appraisals theories and emotion regulation. Ideal starting: 03/27 leibniz-psychology.onlyfy.jobs/de/job/snmy3...

Reproducibility depends heavily on where you start. From authors' final analysis data: ✅: 58.2% fully reproducible 🟡: 32.8% partially reproducible ❌: 9.0% not reproducible From raw data: ✅: 28.4% fully reproducible 🟡: 34.3% partially reproducible ❌: 37.3% not reproducible

Over the past two years, I4R partnered with Psychological Science (@psychscience.bsky.social) on a large reproducibility project. 67 independent teams reproduced 64 articles published in 2024–2025, about 44% of eligible papers. Paper: www.econstor.eu/bitstream/10... Here's what we learned 🧵

Reference limits can exacerbate biased citation behavior! In my current commentary article on the work of @kaileylawson.bsky.social, @brettmurpsych.bsky.social, et al. (2025), I provide empirical support for this thesis. Now published #OA @collabrapsychology.bsky.social 👉 doi.org/10.1525/coll...

Researchers in moral psych: @sarahmlr.bsky.social is now presenting the newly developed and validated eMFV vignettes at #EASP2026, assessing moral wrongs AND upholdings across different contexts and for all moral foundations. Reach out to her if you’re interested in using the vignettes! 🤓

Closing our day on science reception at #EASP2026 with intense poster discussions! I presented an overview of the ambivalent effects of sharing personal details in scicomm and @kduermeier.bsky.social shared our data revealing scientists’ critical perspectives on Citizen Science. #SciReLab

Now @lenazohm.bsky.social shares her research on expert trespassing: people do - at least somewhat - recognize it when scientists transgress the boundaries of their expertise and this might lead to (small) losses of trust. #SciReLab

Had a great time presenting my current work on epistemic injustice and trust in science at my first #EASP2026. Thanks for all the feedback! Happy to be part of the conference!

Now at #EASP2026: The symposium organized by @svenjabfrenzel.bsky.social and @kaisassenberg.bsky.social discusses how people high in conspiracy beliefs might be drawn to deviance such as trusting “outlaws” and supporting non-normative action. 👽

Bringing together psychology of science, computational methods, and social psych to explain how social influence spreads within academic (online) communities: It’s not so much single academic influencers but the community that drives change. Great talk by @abitter.bsky.social at #EASP2026! 🤓

@marlephie.bsky.social and I are searching for a postdoc in SciComm research. Feel free to contact us before applying!

📣 Dear #CitizenScience crowd! 📣 This October (5+6), we are organizing a SYMPOSIUM in collab with @pcstnetwork.bsky.social at the wonderful @mfnberlin.bsky.social in Berlin. We welcome PRACTICAL and RESEARCH perspectives on "Building Knowledge Together: #CitizenScience, #Communication & #Trust".

How does Nazi propaganda influence the emotions of Germans today? In a registered report in EJSP Lara Ditrich, Katharina Bernecker and I tested the affective consequences of Nazi propaganda pictures shown among pictures of Nazi terror on recipients emotions. onlinelibrary.wiley.com/doi/10.1002/...

Moral psychology flourishes because of our variation in moral values both within and across cultures. I'm happy to see that our registered report protocol for developing and validating the MFQ-2 in German populations is out now! Next up: Data collection and analysis ⚖️ 💻

New preprint available: Transparency and open data are important. In contrast to Elson et al. (2026) doi.org/10.31234/osf..., who have called for non-anonymized data in metascience, we argue for a more nuanced approach to prevent unjustified harm for authors of original work doi.org/10.31234/osf...

Looking forward to meeting everyone at the EASP small group meeting on "Counterfactual thinking and its role in cognition and communication" starting later today here in Groningen sites.google.com/rug.nl/count...

We're looking for a PhD student working on the (mis)perception of social norms in social networks (in collaboration with Vincent Buskens at Utrecht University). Deadline: April 1, 2026. More information here: socion-program.org/vacancy/phd-...

🧵 New paper alert! People enjoy eating meat but often feel uneasy when being reminded that it comes from animals. To understand how people avoid this conflict, our new study explores how food preparation helps people mentally separate meat from its animal origins. Here’s what we found 👇 1/9

Researchers are often advised to "reveal the person behind the science" in #scicomm to appear more approachable and trustworthy to their audiences. But does this really work? 🤔 In this short piece for Current Opinion in Psych, I review the recent literature... 👇 1/3 doi.org/10.1016/j.co...

In a new preprint led by @abitter.bsky.social we tested whether open data is useful for reproducibility and usage based on automated and human assessment of data FAIRness. The short answer is: in the majority of cases not really. For more information 👇

The deadline for the meeting on counterfactuals is coming up. Don't forget to send in your contribution.
