from Wikipedia, the free encyclopedia

Diederik Alexander Stapel (born October 19, 1966 in Oegstgeest ) is a former university professor and Dutch social psychologist .

life and work

Diederik Stapel studied psychology and communication science at the University of Amsterdam and graduated in 1991. He then maintained research collaborations with the University of Chicago (1991–1992) and the University of Michigan (1996) and worked temporarily as a consultant. He received his PhD in social psychology from the University of Amsterdam in 1997. From 1998, his research was funded by a five-year grant from the Royal Netherlands Academy of Sciences .

In 2000 Diederik Stapel was appointed professor for cognitive social psychology at the University of Groningen . In 2002 he was granted research funding from the “Pioneer” program of the Netherlands Organization for Scientific Research. Since 2007 he has taught at the University of Tilburg .

Diederik Stapel published over 100 articles during his academic career and was editor of books and international journals. Many of his publications have received wide media coverage around the world. An example of this is the study published in March 2011 with Siegwart Lindenberg in the journal Science , according to which untidy environments encourage the use of stereotypes and discrimination . A press release published by Diederik Stapel and colleagues in 2011 also caused a stir, claiming that people who think about eating meat behave less socially than other people.

Scientific misconduct

In September 2011 it became known that Diederik Stapel had falsified research data . Young scientists from Stapel's research department had contacted the rector of Tilburg University, Philip Eijlander, and informed him of their suspicion that Stapel's data were not real. Confronted by von Eijlander with these allegations, Diederik Stapel admitted to having invented data. He was then suspended from his duties and, according to Eijlander, he will not return to university operations. A commission headed by Willem Levelt was tasked with investigating the extent of the forgeries.

In an interim report, the commission found that Diederik Stapel had falsified data on a large scale. At least 38 articles published in the major socio-psychological journals contain fictitious data. Over 150 other publications are still being examined. The fraud goes back to at least 2004. It seems that Stapel carried out the forgeries alone and without a knowledge of it. The commission attributes the fact that the data falsification was not discovered earlier to the sophisticated falsification method, deliberate manipulation by young scientists, abuse of power and insufficient scientific criticism. In response to the report, Stapel voluntarily returned his doctorate to the University of Amsterdam on November 9, 2011, stating that his behavior over the past few years was incompatible with the obligations arising from the doctorate.

The interim report does not name the studies that have already been identified as falsified; a list of the falsified work should not be published until the investigations have been completed. The Science paper on the effect of messiness on stereotyping was withdrawn by Stapel and Lindenberg on December 2, 2011 because it contained falsified data. In addition, it is also considered likely that the results of the meat examination are bogus. By April 2013, 50 publications had been withdrawn. By September 2016 the number rose to 58.

The criminal proceedings against Stapel were discontinued in July 2013 with the condition that they had to serve 120 community hours; Stapel had not embezzled state funding for personal purposes, but mostly spent it on the employment of doctoral students, whose work, however, was based in part on fabricated data.
