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

[134] Figuring Out Figure 1 - Data Colada

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...
