Instances of Scientific Misconduct

Diederik Stapel

Diederik Stapel, a former social psychology professor, conducted scientific fraud and fabricated his data at least 50 times. Many of his published works were with leading journals such as Science. He worked for Tilburg University in the Netherlands and was caught in 2011 for fraud. Stapel had a habit of secretly changing small details of his data to work in his favor, which later led to full fabrications of data sets. The scientific misconduct was so well-done that he was not caught until many years later. Eventually, he received many retractions due to the fabrication of his data, concerns about his data, etc. Stapel even had criminal proceedings due to his fraudulence, making him an infamous researcher.
