The Drenth Committee (https://www.commissielevelt.nl) has found evidence of fraud in this article, committed by author Stapel. His coauthor was unaware of his actions, was not in any way involved in the generation of the data, and agrees to the retraction of the article.
The study has been cited 12 times, according to Thomson Scientific’s Web of Knowledge.
And Social Psychology Quarterly has retracted “The Norm-Activating Power of Celebrity: The Dynamics of Success and Influence,” cited twice:
Social Psychology Quarterly retracts the article “The Norm-activating Power of Celebrity: The Dynamics of Success and Influence,” by Siegwart Lindenberg, Janneke F. Joly, and Diederik A. Stapel, which appeared in the March 2011 issue (74(1):98–120; DOI: 10.1177/0190272511398208). This retraction stems from the results of an investigation into the work of Diederik A. Stapel (https://www.commissielevelt.nl/noort-committee/publications-examined/), which finds strong evidence of fraud in the dataset supplied by Stapel. His coauthors had no knowledge of his actions and were not involved in the production of the fraudulent data.
