Professor Richard Wiseman, University of Hertfordshire

“Evidence is vital to every aspect of our lives. Whether it is someone trying to sell you a car, convince you that you need the latest hi-tech gadget, claiming to be psychic, or saying that God exists, people should ask themselves one key question - 'what's the evidence?'”

Prof. Richard Wiseman is Professor of the Public Understanding of Psychology at the University of Hertfordshire, and is also an author.
