Richard Wiseman
From RationalWiki
Richard Wiseman (born 1966) is a British psychologist, a former professional illusionist, a popular-science writer and a sceptic. He holds the chair of Public Understanding of Psychology at the University of Hertfordshire.
His basic research involves luck, the psychology of change, illusion, humour, belief, and the paranormal - basically, why people believe weird things. Like all good scientists, and anyone with a modicum of common sense, he is skeptical of absurd sounding claims not backed by solid evidence.
He also runs a very popular youtube channel called Quirkology. Videos include illusion demonstrations, bets you will always win and a subtle questioning of your observations.
