New post on Data Colada. I spent a very long time trying to figure out a figure in a methods paper that is not in my area of expertise. It shows extremely *negative* R-squared values from replications of a true effect. The question on my mind was: WHAT?? I learned some stuff. datacolada.org/134

I am sometimes asked (e.g., today) for advice for conducting meta-analysis. Shoudl i use PET-PEESE or Trim-and-fill? I feel like being asked what hat color is best to wear during a rain dance. Data Colada posts about (against) meta-analysis: datacolada.org/archives/cat...

An update on Gino's lawsuit against us (Data Colada). We had a hearing about our motion to dismiss, and we've learned some legal things along the way. No big news yet, but some details: datacolada.org/116

Part 1 of a two-part series on Freakonomics: Why is there so much fraud in academia? Interviews with @briannosek.bsky.social Leif Nelson, @joesimmons.bsky.social, @urisohn.bsky.social, Max Bazerman, and me. Part 2 (about what journals are doing) coming next week freakonomics.com/podcast/why-...

I’m a fan of trying to quantify how often reviewers & editors check authors’ preregistrations (eg, by @syeducation.bsky.social), but also we should not forget that reviewers fail to check for deviations from a priori plans in 100% of unpreregistered studies. Because they can’t.

Finally! New policies for Psych Science in 2024 (part 1): Editorial 1: https://www.psychologicalscience.org/publications/psychological_science/vazire-editorial Editorial 2 w/ @tomhardwicke.bsky.social : https://www.psychologicalscience.org/publications/psychological_science/hardwicke-editorial

Very excited that @i4replication.bsky.social is going to be doing annual stress tests of papers published in Psych Science. It’s amazing to see what they’ve done in econ & poli sci, and great that they’re expanding to psych!

Not your grandparents’ psych journal

Zoé Ziani (who isn't on BlueSky AFAICT) has posted a long post-mortem on the Gino-Ariely case. She explains how she came to suspect Gino’s work, the resistance she met during her Ph.D., her experience working with Data Colada, and the lessons business academia should learn from these scandals...

THE REFORM IS COMING FROM INSIDE THE HOUSE.
