Since AI slop is again all over Scientific Reports, a thread on the economics of grey-zone publishing. Why does slop keep getting published? What does it mean for science? How can we stop this? Background readings: Understand the strain: tinyurl.com/2b6wxx5r Stop the drain: tinyurl.com/3jfscscy
An obviously AI-generated figure with AI slop and fake text all over it, recently published in Scientific Reports.

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
Experimentology cover: title and curves for distributions.

I agree that such carelessness is bad. But I have also seen several cases where an IRB forbid researchers to share any data (even cleaned/anonymous) for blanket privacy reasons. That’s bad too. There is a difficult trade-off/conflict between transparency ethics and privacy ethics, needing balancing.

Das Problem ist, dass es bei opt-out real nicht zu mehr Organspenden kommt, da die Familien das letzte Wort haben und aufgrund von opt-out nicht genau wissen, was der Verstorbene explizit gewollt hätte. “Forced choice” (z.B. beim Beantragen eines Ausweises/Führerscheins) würde besser funktionieren.

Credit statements are useful ex-post, but may create wrong incentives ex-ante and backfire. I think each author should vouch for the whole paper, encouraging mutual control. Credit statements compartmentalize responsibility, reduce mutual control and costs to collaborate with untrustworthy others.

2) Does the argument provide sufficient reasoning or evidence that this different treatment effect is expected to be observed? If the two conditions are fulfilled, then there is a next paper (or additional work for this paper). If not, then the criticism is either too broad or too speculative. 3/3
030
Ben Greiner @bgreiner.bsky.social · 07/01/2025
I think the soundness check for any external validity criticism should include two components: 1) Is the criticism specific enough? Does the argument specify that a particular *treatment* effect/mechanism should not be observed in a particular important different environment? 2/3
110
Ben Greiner @bgreiner.bsky.social · 07/01/2025
Agree. I find most of the external validity criticisms simply boring. (It’s also what my undergraduate students come up with first when asked to state limitations of an assigned reading.) After all, an external validity concern can be raised for almost *any* study using *any* method/dataset. 1/3
