How FAIR is shared data in psychology?
We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable!
What relates most to differences in FAIRness? #Repository choice.

Our lab has the capacity to test ~500 uni students each semester
If you’re a researcher in cognitive psychology or metascience and need data collection support, we’d love to collaborate. We can help collect high-quality data from a large student sample.
Get in touch to discuss potential projects!

It’s been a pleasure presenting our recent work on neural biomarkers of morality at #ICANDay2025. Hopefully, shifting from brain maps to neural models will help us to develop a more precise and reliable moral neuroscience.
Very inspiring keynote by @fhopp.bsky.social at #ICANDay2025: “From Maps to Models: A Paradigm Shift for Moral Neuroscience.” A fascinating case for moving beyond brain mapping toward predictive modeling and multivariate neural decoding to better understand morality in the brain.

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 👇
