Some more thoughts on the Stapel saga.
In most fraud cases Diederik Stapel told his students that he would perform his experiments, collect the data, do the analysis, and give the students the results. Some students wanted to be at the experiments (a good suggestion, because you can learn a lot from it), but he wouldn’t allow them. A few students wanted to see the raw data, but when they pressed him he expressed doubts whether they were good enough to be his PhD students. A filthy intimidation tactic if you ask me. But not only his students were duped: other academics, like the Dutch professor Roos Vonk, co-authored articles that turned out to be based on fake data. In the end the whole fraud came out because a few students finally had the courage to stand up to him (and, possibly, the university board where he had a lot of friends – luckily the board did the right thing and took their complaints seriously). Other students, who allowed themselves to be intimidated, now have flawed dissertations. A few of them have left science because of the affair.
Dear students, learn from this. I promise I won’t cook the books, but don’t take my word for it – don’t take anyone’s word for anything. Not just your thesis supervisor. After you graduate you will work with other people, like your boss or your co-authors. They can make mistakes. They can lie. When your name is on a proposal, a thesis, or an article, than you (and your co-authors) are responsible for its contents. Convince yourself that its contents is correct. Yes, I do the same with your contributions.
I know that in some cultures it is impolite to question the advice of your superiors, much like foot soldiers are supposed to follow their sergeant’s orders. That may work in the army, but we’re not in the army here. The one order I give you is not to take orders from me.
