Diederik Stapel’s reinvention as a teacher at a college in the Netherlands has proven to be short-lived.
According to the NRC Handelsblad, Stapel resigned from the job at Fontys in solidarity with Anton Dautzenberg, whose contract at Fontys was terminated and with whom Stapel had co-authored a play. A performance of that play was cancelled last month.
Stapel, who has 54 retractions, tells Retraction Watch that he “had to resign:”
I was hired to teach a course from September to May. This is also clear from the study guide. I would teach till May. Now they changed that and say it is not a course, only a few guest lectures.
Stapel also admitted today that he had been leaving comments on Retraction Watch using a fake name, “Paul,” and referring to himself in the third person, which we consider sock puppetry. While we welcome anonymous and pseudonymous comments, when we have reasons to believe that a commenter is to be violating our comments policy against unverified claims — as pretending not to be Stapel when you are actually Stapel would be doing — we will try to determine whether the comment is accurate as submitted. When we asked “Paul” whether he was Stapel, he would not say, so we added an editor’s note to all of his comments.
Now he has come clean. In a comment left this morning on the post about his teaching appointment, Stapel writes:
Hello, my name is Diederik Stapel. I thought that in an internet environment where many people are writing about me (a real person) using nicknames it is okay to also write about me (a real person) using a nickname. ! have learned that apparently that was —in this particular case— a misjudgment. I think did not dare to use my real name (and I still wonder why). I feel that when it concerns person-to-person communication, the “in vivo” format is to be preferred over and above a blog where some people use their real name and some do not. In the future, I will use my real name. I have learned that and I understand that I –for one– am not somebody who can use a nickname where others can. Sincerely, Diederik Stapel.
