Jonathan St. B. C. Evans

Jonathan St B. T. Evans is a British cognitive psychologist, currently Emeritus Professor of Psychology at the University of Plymouth. In 1975, with Peter Wason, Evans proposed one of the first dual-process theories of reasoning, an idea later developed and popularized by Daniel Kahneman. In a 2011 Festschrift, Evans' peers described him as "one of the most influential figures in the psychology of human reasoning".
