Dr. Karen Franklin notes that while the Diederik Stapel incident is the latest, it isn't isolated. Racism in baseball umpires, ESP, if there has been a popular tripe study thrown out to catch headlines, someone in psychology has used lousy pseudoscience to create it.
The problem isn't just in Holland, though they obviously have a high level of concern right now. Dr. Jelte M. Wicherts and Marjan Bakker, both from the University of Amsterdam, did a random sample of 281 psychology papers for statistical errors and found that about half of the papers in high-end journals contained statistical errors and that about 15 percent of all papers had at least one error that changed a reported finding, almost always in opposition to the authors' hypothesis.
In the US, a survey of over 2,000 American psychologists found that 70 percent acknowledged cutting corners in reporting data and a third said they had reported an unexpected finding as predicted from the start and 1 percent admitted to falsifying data. Psychologists who claim their surveys of college students are perfectly valid will have a hard time denying surveys of actual psychologists as 'science'.
But the problem is that it leads to distrust of applied psychology fields, like in forensic psychology - and that is where Franklin has the highest level of concern about the impact of fraud in the woo parts of the field.
