A previous version of this post was supposed to go live in January 2019. But the day before it was scheduled, the Data Colada team (Uri, Leif, and Joe) received an email that we took to be a potential death threat. After discussions with the local police, the FBI, and our families, we decided to…
[116] Our (First?) Day In Court
“Any update on the lawsuit?” That is the most common question any of us is asked. It is usually preceded by an apologetic preamble, like, “sorry if this is a sensitive question,” or “I don’t know if you’re tired of talking about this, but…” The reality is that, for the most part, our actual sensitivity…
[115] Preregistration Prevalence
Pre-registration is the best and possibly only solution to p-hacking. Ten years ago, pre-registrations were virtually unheard of in psychology, but they have become increasingly common since then. I was curious just how common they have become, and so I collected some data. This post shares the results. The data From the Web of Science…
[114] Exhibits 3, 4, and 5
We recently presented evidence of data tampering in four retracted papers co-authored by Harvard Business School professor Francesca Gino. She is now suing the three of us (and Harvard University). Gino’s lawsuit (.htm), like many lawsuits, contains a number of Exhibits that present information relevant to the case. For example, the lawsuit contains some Exhibits…
[113] Data Litigada: Thank You (And An Update)
Thank You A few months ago we reported evidence of data tampering in four papers that have since been retracted (or re-retracted) (Colada[109] .htm). A few weeks ago we were sued for doing so (Vox .htm). Lawsuits can be very expensive, and a thoughtful and generous group of colleagues and supporters started a fundraising campaign…
[112] Data Falsificada (Part 4): "Forgetting The Words"
This is the last post in a four-part series detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino. It is worth reiterating two things. First, to the best of our knowledge, none of Gino’s co-authors carried out or assisted with the data collection for the studies in this…

This is the third in a four-part series of posts detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino. It is worth reiterating that to the best of our knowledge, none of Gino’s co-authors carried out or assisted with the data collection for the studies in this series….
[110] Data Falsificada (Part 2): "My Class Year Is Harvard"
This is the second in a four-part series of posts detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino. It is worth reiterating that to the best of our knowledge, none of Gino’s co-authors carried out or assisted with the data collection for the studies in this series….
[109] Data Falsificada (Part 1): "Clusterfake"
This is the introduction to a four-part series of posts detailing evidence of fraud in four academic papers co-authored by Harvard Business School Professor Francesca Gino. In 2021, we and a team of anonymous researchers examined a number of studies co-authored by Gino, because we had concerns that they contained fraudulent data. We discovered evidence…
[108] MRAN is Dead, long live GRAN
Microsoft has been making daily copies of the entire CRAN website of R packages since 2014. This archive, named MRAN, allows installing older versions of packages, which is valuable for reproducibility purposes. The 15,000+ R packages on CRAN are incessantly updated. For example, the package tidyverse depends on 109 packages; these packages accumulate 63 updates, just…
