In one of the more bizarre twists of the Dan Ariely saga, there is a huge issue of provenance in one of Dan Ariely’s studies. The study in question is Dan Ariely’s Ten Commandments study at JMR. The hugely impactful paper has over 3,000 citations but unfortunately failed to replicate in a large-scale systematic replication project. The person who Ariely claims ran the study for him at UCLA, Professor Aimee Drolet Rossi, has no recollection of running the study for him at all. That would be fine if she just couldn’t remember, but there are two more relevant facts:
- Dan Ariely was a super star even at that time so it would have been very memorable if she had collected data for him.
- The data for Ariely’s Ten Commandments study, the study in question, could not have come out of the generating process used by the subject pool Drolet Rossi managed at that time.
Unfortunately for Ariely, the Israeli press won’t let the issue die and has been digging into this issue of provenance rather deeply. This has led to two things:
- Dan Ariely pressuring Rossi to cover for him
- Aimee Drolet Rossi posting their email exchanges to EJMR
According to Aimee Drolet Rossi, the other two authors, On Amir and Nina Mazar have claimed to not remember where the data came from (though one of the emails below seems to possibly involve On Amir as claiming to receive the data in the exchange that never happened). That means one of the most cited studies in the history of Journal of Marketing Research is completely lacking in provenance. The trail stops at Dan Ariely but his story that it was run at UCLA does not check out.
Here are all of the emails that I could gather from the EJMR thread. They should be clickable to zoom in on the a bit if needed:
