In recent years, mathematician Pepijn van Erp has risen to prominence within the skeptical movement in the Netherlands. He started blogging about flawed application of statistics in both scientific and pseudoscientific articles, and got involved with Stichting Skepsis as a board member in 2012.
Nowadays he regularly writes articles on various dubious claims in an investigative journalistic style on skeptical blog KloptDatWel.nl (mostly in Dutch) and his own website (mostly in English). Van Erp is occasionally invited to give his expert opinion on radio shows about conspiracy theories, fake news and other topics that skeptics are concerned about. To him, skepticism is ‘interesting and funny’, but also a ‘civic duty’ to protect people from harm.
The team of Guerrilla Skepticism on Wikipedia has written two new biographies about Van Erp, one in English and one in Dutch, to explain to the general public what his activism is about.
