Pepijn van Erp

Dutch mathematician and skeptical activist

Mathematics graduate Pepijn van Erp, born in 1972 in Goirle, Netherlands, directs his analytical training toward investigating pseudoscientific claims. Educated at Radboud University, where he completed his degree in 1999, he transitions from professional statistical consulting to the active scrutiny of dubious public narratives, often applying rigorous methodology to challenge assertions that lack valid scientific evidence.

Professional Background

After his academic tenure at Radboud University, Van Erp pursued a career as a statistics consultant for PTT. His professional trajectory included a period of residency in Tanzania between 2002 and 2005. Furthermore, he served as secretary for the Stichting Nijmeegs Universitair Fonds, known as SNUF, a role he maintained until 2012.

Skeptical Activism

In 2011, Van Erp engaged with Stichting Skepsis, assuming a position on the board in March 2012. He frequently evaluates the validity of fringe claims, distinguishing between legitimate scientific work and pseudoscience. His involvement in public discourse saw him challenge the editorial standards of the television program De Wereld Draait Door in 2013 regarding the promotion of facilitated communication for Niek Zervaas, a practice widely regarded as unproven.

Legal and Institutional Challenges

Van Erp faced litigation in 2016 initiated by Ruggero Santilli, an American-Italian nuclear physicist, following critical commentary regarding Santilli's scientific theories. The legal action, which targeted Van Erp, his webhost, and the Stichting Skepsis chairman, resulted in the foundation's dismissal in August 2018, while the case against Van Erp reached a settlement shortly thereafter. Additionally, in 2016, his public criticism of a Philips workshop concerning energy medicine and meridian-mapping applications contributed to the company's decision to cancel the event.
