Eric-Jan Wagenmakers
Eric-Jan Wagenmakers is a Dutch mathematical psychologist. He is a professor at the Methodology Unit in the Department of Psychology at the University of Amsterdam. Since 2012, he has also been Professor of Neurocognitive Modeling: Interdisciplinary Integration at UvA's Faculty of Social and Behavioral Sciences. A noted expert on research methods in psychology, he has been highly critical of some dubious practices by his fellow psychologists, including Daryl Bem's research purporting to find support for the parapsychological concept of psi, and the tendency for psychologists in general to favor the publication of studies with surprising, eye-catching results. He has also been active addressing the replication crisis in psychology, including by helping to conduct a series of studies aimed at reproducing a 1988 study on the supposed effects of smiling on the perceived funniness of cartoons.
