Things We Don't Know Anymore

The last few years haven’t been easy on psychological science. Don’t get me wrong – the field in itself is flourishing, boasting an ever-increasing number of publications, journals, conferences, faculty positions, and university graduates all over the world. It has gained more and more respect and acceptance, both in academia and society. The case of Harvard evolutionary biologist and primate researcher Marc Hauser’s fraudulent publications was already fading from our minds when in September 2011, the discovery of the scientific misconduct by the Dutch social psychologist Diederik Stapel shattered the grounds of psychological science. In at least 50 cases of scientific fraud that have been discovered by the Levelt Committee, Stapel had doctored, mangled, and completely fabricated datasets to successfully publish in the field’s top-ranked outlets - up to the most prestigious journals like Science. Among Stapel’s highly regarded publications were findings on how untidy environments encourage racist discrimination, or how to reduce racist biases in judges' legal decisions on minority defendants. Nullifying the content of these publications constitutes a setback for social psychology, and - to a somewhat lesser extent – society overall.
Although they work in a highly competitive environment, we trust scientists to be committed to finding the truth. And when playing it smart, like Stapel, it is quite easy to abuse this trust for personal gain in the form of a prestigious academic career. Instead of looking for the truth, Stapel was on a
quest for aesthetics, for beauty, as he was quoted saying by the New York Times. One might think that it’s not that much of an issue - Stapel got caught after all! Reaching for the stars he committed fraud, but got brought back down to reality when his deeds were unveiled, so the system works. But does it really?
