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

Wahou, so refreshing this first day at the meta-science conference #PSE8. How did I change my mind from science is broken to yes but great minds are working on it!
I also received very positive feedback on my work on outlier detection (that should be out as a preprint soonish)

Thanks to everyone that was interested in my poster for the great conversations and discussions!
The preprint on reporting, open science, and trustworthiness in simulation studies is available here: osf.io/jn9sy_v2
Ready for day two of #PSE8!

Very relevant following the keynote by Leif Nelson! #PSE8
Dear colleagues - we want to better understand perceptions of data fraud and its detection and need your support! Are you currently a #researcher in #psych (or related fields) working with #data? Perfect - please respond to & share this short study (7min): sosci.rlp.net/detection/?r... Thank you!! 🫶

Insights from the #PSE8 conference
Day 2: I was particularly struck by a presentation from Prof Leif Nelson on the detection of problematic data.
I wonder how many of us have came across problematic papers - or datasets and don’t what to do!?

This was a banger of a talk.
Leif Nelson pointing out that lawsuits are not great for science, as we need to be able to criticize others without the threat of having to pay huge legal fees, and I vest a ton of time, to defend ourselves.

First time presenting this work to a room of scientists. General reaction to learning about how science is evaluated for use in court: 🤯
Edith Beerdsen from Temple University, USA, continues the afternoon about the role that scientific error plays in the courtroom, providing a perspective on Scientific Error from how science influences the practice of law. #PSE8

Leif’s #PSE8 keynote was ridiculously good, basically a live episode of @datacolada.bsky.social ... if anyone deserves a detective/sitcom series based in their work, it’s Leif, not Ariely – take note @netflix.com
Neil Nelson will give the first keynote of the day, about finding lies in the work of scientists. He argues we need to be able to detect what is not true when we interact with the scientific literature. #PSE8

We continue with the field of medical imaging with deep learning, in a talk by Attila Simkó from Umeå University, talking about computationally reproducing code.

We continue with a discussion about theory specification in social psychology by Anand Krishna from Wurzburg, Germany. #PSE8 After decades of calls for stronger theory, how do we actually specify more detailed theories?

Second keynote of the day, Femke Truijens, from the Erasmus University, talking about what it means to be an 'error' in mental health research. #PSE8 After this we will have posters, drinks, and continue discussions over dinner!

When we want to distinguish erroneous results from true effects, we need to perform replication studies where we systematically vary factors that aim to isolate the source of the error in repeated conceptual and direct replications. We need to "probe" for sources of error!

Douglas Allchin summarizes many examples in the history of science where artifacts replicate very well. #PSE8
Lovely examples (like N-rays) of the trivial truth that successful replications do not imply the truth. But replications are essential to figure out what's what!
