As I noted in my post, the Smeesters case is unique. While earlier cases of fraud in psychology, including Stapel Karen Ruggiero and Marc Hauser, were uncovered by internal whistleblowers using inside information, Smeesters was found out by an external source using statistical sleuthing. At the time of writing, that source was anonymous but on Thursday, he was revealed to be Uri Simonsohn, another social psychologist from the University of Pennsylvania.
