He received his BSc from the University of Waterloo and his Ph.D. in social psychology from Harvard University. He studies the mysteries of subjective experience and asks such deep philosophical questions as: Why are humanoid robots creepy? Why do ghosts always have unfinished business? Why do grandma's cookies taste the best? And why do adult film stars seem stupid? His research suggests that these questions—and many more—are rooted in the phenomenon of mind perception. Mind perception also forms the essence of moral cognition.
