1. The Datacolada investigation
2. In 2010 Ariely supposedly collected from an insurance company: “In an interview on NPR he claimed he had data from Delta Dental that showed high rates of misdiagnosis from X-Rays. Delta Dental had to intervene and make the correction that they never provided Ariely with this data because they never collected such data.”
3. Check out this"Expression of Concern" (https://journals.sagepub.com/doi/10.1177/09567976211035782) published in July 2021 for one of his papers in Psych Science. "The corresponding author of the article and coauthor of this statement, Dan Ariely, attempted to locate the original data in an effort to resolve the ambiguities but was unsuccessful."
4. John list found that Ariely's results did not replicate: Maniadis, Z., Tufano, F., & List, J. A. (2014). One swallow doesn't make a summer: New evidence on anchoring effects. American Economic Review, 104(1), 277-90.
5. Ariely was suspended from MIT and eventually left the institute after he conducted an experiment using electric shocks without proper approval from the ethics committee.“When we asked one of the study investigators why Ariely hadn't requested the necessary permissions, they explained that "Ariely likes to cut corners, and he doesn't think he needs to follow the rules like everyone else. He didn't think he'd get caught."
6. "Just read on LinkedIn a post by an accounting prof who had contacted him. He wanted to replicate a paper that used a modified shredder. However, they weren’t able to modify the shredder, even with the help of an engineer. Dan said to the accounting guy that he simply made the modifications with a screwdriver. That is where the story ends, the paper was not relocated because the shredder could t be modified in the way claimed in the Ariel paper."
7. . In a famous 2008 study, he claimed that prompting people to recall the Ten Commandments before a test cuts down on cheating, but an outside team later failed to replicate the effect.
8. This analysis finds that ven when Ariely didn't make up the data, he followed very strict p-hacking to get conclusions: https://replicationindex.com/2021/08/27/dan-ariely-and-the-credibility-of-social-psychological-science/
