#pse8 — Public Fediverse posts

Thanks #pse8 for three days of error and the new sticker on my laptop!

Very pleased with these new hex stickers, for the #PSE8 conference, but also for our TOSTER package, Metacheck, and my Improving Your Statistical Inferences book and course :)

The Metacheck team (https://www.scienceverse.org/metacheck/) and some interested collaborators are hackatonning away on how to create and validate new metacheck modules to automatically detect information in scientific papers. #PSE8

On the way to #PSE8 this morning, I saw a Great Crested Grebe (Podiceps cristatus) and recorded it as an observation on #inaturalist . This could be seen as an assertion of the type <observer><observed><bird>
<timestamp><location><observation identifier>, much like in #nanopublications.

Of course, the #nanopublications #hackathon at #PSE8 has its own space in the nanopublication network, all built using nanopublications.

The slides are up for the #nanopublications session at the #PSE8 #hackathon today:
Making Errors and Uncertainty FAIR: A Nanopublications Hackathon for Machine-Actionable Scientific Error Reporting. Zenodo. https://doi.org/10.5281/zenodo.18627181

#openscience #FAIRdata

We are starting the 3rd day of #PSE8, which is completely dedicated to hackathons. People can join one in the morning, and one in the afternoon, and collaboratively work on projects, or develop new ideas for future projects!

The #PSE8 #hackathon day is about to start with pitches for the individual morning sessions. https://w3id.org/spaces/PSE8

Final keynote and talk of the #PSE8 conference, by František Bartoš, University of Amsterdam, talking about the idea of robustness reports.

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

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?

We continue with James Steele (wearing his 'stay calm and read Paul Meehl' shirt) who is in a high pace running us through his views on how we develop and test strong theories. #PSE8

We are back at the second day of #PSE8! Liz Tenney from the University of Utah is stepping in to cover for an I'll speaker, and talking about doing replication in the trenches - reflecting on the practices of doing replication studies.

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!

Now the first keynote of the conference, Vlasta Sikimić, who will talk about the importance of intellectual virtues, and their role in a future in which we might have a bigger role of AI in the evaluation or review of scientific grants and papers. #PSE8

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!

Now Douglas Allchin from the University of Minnesota, taking a history of science perspective on errors in science. #PSE8 He will dig into Joseph Priestley's 1771 experiment on the restoration of air (unknown to most audience members!)

Now Aurélien Allard with the second talk of #PSE8: How is it possible that there is massive scientific progress, even thought there is a lot of scientific error?

I love this mural at the University of Leiden (Netherlands).
A good reminder for academics nowadays .

If you are also at the #PSE8, come talk to me about funding opportunities for non-research projects about Open Science and #FAIRdata and software

I’m at the 8th edition of the Perspectives on Scientific Error today, this time in Leiden (NL). Excited about a day of critical discussions and nice people!

#openscience #pse8

Everything is ready for the Perspectives on Scientific Error conference that starts tomorrow in Leiden! I look forward to hanging out with the mix of metascientists, philosophers of science, and statisticians! So many old friends will be there (and hopefully some new ones)! #PSE8

@tomstafford I assume that the #PSE8 organizers will announce at some point when and where #PSE9 is expected to take place, and that both the #conference website and its nanopublications representation will hopefully soon provide that information as well.

Assuming that the conference "Perspectives on Scientific Error" 2026 (also known as PSE8)
https://perspectivesonscientificerror2026.wordpress.com/
has the #hashtag #PSE8, I am happy to report that it now also has a presence in the #nanopublications ecosystem at https://w3id.org/spaces/PSE8
In preperation for the nanopublications hackathon om 2026-02-13, we are going to use that space to experiment with the use of nanopublications for conference microblogging.
