New #EEGManyLabs paper out in Cortex! We asked whether contralateral delay activity, or CDA, can serve as a reliable EEG marker of visual working memory capacity. doi.org/10.1016/j.co...

Still a few days to apply!

I’m hiring a PhD student! The candidate will work alongside @zefreeman.bsky.social, who is joining our research group as postdoc. jobs.unibe.ch/job-vacancie...

Are you interested in Shaping an Open Science Culture? Apply for this 2 year post-doc position at UMC Amsterdam. Joeri Tijdink is the PI, but you will work in a large interdisciplinary team (including me). werkenbij.amsterdamumc.org/en/vacatures...

The multilevel extension to RoBMA was just published in BRM (link.springer.com/article/10.3...). Together with @maxmaier.bsky.social and EJ Wagenmakers, we developed a 3-level version of RoBMA which allows analysts to adjust for publication bias in meta-analyses with estimates nested within studies.

Ian Hussey (@ianhussey.mmmdata.io) contacted me about the recurring problem of unusually large SMD values appearing in published meta-analyses. Very large SMDs can result from using SEs in place of SDs in their calculation, which is a mistake I have also seen in practice. 1/4

SHOCKING stories of data fabrication Tim Errington shares a never-before-told story of data fabrication in cancer biology. Scientists go to extreme measures, even engaging in data fabrication, to secure a publication in prestigious journals. #science #truth #medicine #stem #shorts

New preprint: Preregistration is supposed to make research more transparent. But if registry records aren't kept up to date, the transparency benefit erodes. We checked 1,137 psych meta-analyses on PROSPERO and found the records are systematically out of sync with reality osf.io/preprints/ps...

New preprint: How to analyze a replication study. osf.io/preprints/ps... Following methodological falsificationism, claims in replications should follow the original test (so typically p<0.05). We also discuss some consequences a coherent philosophical approach to statistics. >

😶‍🌫️ You can see how bad I am at science communication as I entirely forgot the most important thing: Try out the Replication Atlas here: forrt.org/flora-replic...

Introducing the #ReplicationAtlas: The FLoRA (FORRT Library of Reproduction and Replication Attempts) lets you browser over two thousand (!) pairs of original and replication studies. Search by DOIs/keywords and find out about replications from your field, maybe even replications of your own work.

Selecting an effect size for power analysis is hard. Many researchers fall back on Cohen's thresholds, but they have no empirical basis and vary wildly by field. Our new paper offers a better option: field-specific effect size distributions built from meta-analytic data doi.org/10.3758/s134...

How much does it cost to buy your way onto a scientific paper? To answer this question (and better understand the global market for academic reputation manipulation), we compiled BuyTheBy, a massive dataset of thousands of advertisements from paper mills in seven different countries. Link below!

We are inviting applications for a two-year postdoctoral position in a collaborative meta-science project on the effectiveness of data and code sharing policies in research-performing organizations. www.tue.nl/en/working-a...

This project also laid the foundation for my broader perspective on the value of Big Team Science as a powerful approach to advancing clinically relevant and globally applicable research.

Three recent papers examined reproducibility of a large sample of findings. Join this webinar to discuss them and explore where the findings converge and differ. 1. SCORE: www.nature.com/articles/s41... 2. I4R: www.nature.com/articles/s41... 3. Meta-Rep: royalsocietypublishing.org/rsos/article...

Should we use error checking tools like Statcheck and GRIM to automatically check for errors in studies in meta-analyses? I wrote a blog post with some insights from a hackathon where we scrutinized this idea. metaresearch.nl/blog/2026/3/...

Early review after reading two chapters. This quality and accessibility of the writing is amazing. Complex topics communicated clearly for a range of audiences. So far—quite a good and useful read.

Has transparency improved in clinical psychology? New cross sectional study from us (Bianca Kotoulas, Justine Blackwell & me). Adoption of transparent research practices has increased between 2012, 2018, & 2024, but aside from coi and funding disclosures, they remain uncommon osf.io/preprints/ps...
