Keeping up with the retraction count of Diederik Stapel is proving to be a, well, staple of this job. Four more retractions brings the figure to 45.
The articles in question are:
- “The unconscious unfolding of emotion,” by Stapel and Kirsten Ruys, which appeared in the European Review of Social Psychology in 2009 and has been cited three times, according to Thomson Scientific’s Web of Knowledge:
The following article is being retracted from publication in European Review of Social Psychology: ‘‘The unconscious unfolding of emotions’’ by Kirsten I. Ruys & Diederik A. Stapel (volume 20, 232–271, DOI 10.1080/10463280903119060). After the Levelt Committee determined this article to be based on empirical articles that contain fraudulent data provided by D. Stapel, the Editors and Publishers of European Review of Social Psychology have retracted the article.

- “Me tomorrow, the others later: How perspective fit increases sustainable behavior,” with co-author Marijn Meijers, in the Journal of Environmental Psychology, cited once. Its retraction notice states:
This article has been retracted at the request of the Editor-in-Chief.
The second author (Diederik Stapel) has been found to have created fraudulent data for this article. A website (https://www.commissielevelt.nl/) contains a first set of publications by D. A. Stapel that are now officially identified as fraudulent.
The remaining author wishes to state that D. A. Stapel is the sole author of the fraudulent data, and the first author of the article was unaware of this. This article obviously represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the review process.
- “Stop Making Sense: The Ultimate Fear,” with Marret Noordewier, published in 2011 in Psychological Inquiry and cited four times:
The following article is being retracted from publication in Psychological Inquiry: “Stop Making Sense: The Ultimate Fear” by Diederik A. Stapel & Marret K. Noordewier (20:4, 245–248, DOI: 10.1080/10478400903448516). After the Levelt Committee determined this article to be fraudulent, the Editor and Publisher of Psychological Inquiry have retracted the article (for further details, please visit the following link: https://www.commissielevelt.nl/leveltcommittee/fraud-determined).
- and “Status concern and financial debts in adolescents,” with co-authors Rob Nelissen and Nils van de Ven, published in 2011 in Social Influence:
The following article is being retracted from publication in Social Influence: ‘‘Status concerns and financial debts in adolescents’’ by Rob M. A. Nelissen, Niels van de Ven & Diederik Stapel (volume 6, issue 1, 39-56, DOI 10.1080/15534510.2010.525855).
