Guy P. Harrison is an award-winning writer and the author of six highly acclaimed books that promote science and reason. Random House named one of his books, Think: Why You Should Question Everything, recommended reading for all first year university students. Guy’s brand of scientific skepticism is positive, constructive and optimistic. He calls poor critical thinking the world’s great unrecognized crisis and believes that millions of lives and trillions of dollars could be saved if more people committed to thinking like scientists in everyday life. Understanding how our brains naturally fool us when we try to separate truth from fiction is crucial to living a safer and more efficient life, he says.
