From Diederik Stapel’s memoir:
When students gave presentations of research that I knew was based on my fake data, I could barely wait for them to finish. Maybe someone would burst the bubble, pointing out a fundamental error that would show that the whole thing was completely fictional. I sat and watched a great show, but I was the only one there who knew that it was just an illusion. I watched students, doctoral candidates, and research assistants talking enthusiastically about their work, and I knew that the data they were presenting were all fake. It was hard to keep up the pretence. What they were presenting was fantastic, as coherent as anyone could hope for. They had the results they’d hoped for, they’d passed the test, they were full of self-confidence, they believed in themselves and in the reliable structure of science, but I knew that their faith was built on sand.
