Third-person bio: Eric-Jan (“EJ”) Wagenmakers is professor in Bayesian Methodology at the Psychological Methods Unit of the University of Amsterdam. His main research interest is Bayes factor hypothesis testing in the style of Sir Harold Jeffreys. Since 2012 Wagenmakers's lab has spearheaded the development of the JASP open-source software program for statistical analyses. Together with Dora Matzke, Wagenmakers authored the course book “Bayesian inference from the ground up: The theory of common sense”, which is freely available on BayesianSpectacles.org. Moreover, with 43 pages and 43 dinosaurs, Wagenmakers's children’s book “Bayesian thinking for toddlers” is a must-have for any toddler with even a passing interest in Ockham’s razor and the prequential principle.
Every year, Wagenmakers teaches two workshops in Amsterdam: with Richard Morey he teaches the two-day course “Theory and Practice of Bayesian Hypothesis Testing”, and with Michael Lee he teaches the five-day course “Bayesian Modeling for Cognitive Science” (based on their book “Bayesian cognitive modeling: A practical course”).
Wagenmakers is a strong advocate of Open Science and the preregistration of analysis plans. He currently chairs the Stichting Skepsis, a Dutch organization dedicated to the promotion and practice of scientific skepticism.
