  • Chris French on the Science of Weird Shit
    Jun 4 2025

    Make a donation to Closer To Truth to help us continue exploring the world's deepest questions without the need for paywalls.

    Chris French's latest book, The Science of Weird Shit, convincingly debunks ESP, communicating with the dead, and alien abduction claims, among other phenomena. All the while, however, French maintains that our belief in such phenomena is neither ridiculous nor trivial; if anything, such claims can tell us a great deal about the human mind if we pay them the attention they are due.

    Chris French is Emeritus Professor and Head of the Anomalistic Psychology Research Unit in the Psychology Department at Goldsmiths, University of London. He is a Fellow of the British Psychological Society and of the Committee for Skeptical Inquiry and a Patron of Humanists UK. He is the coauthor of Anomalistic Psychology: Exploring Paranormal Belief and Experience.
