Guy P. Harrison (born October 8, 1963) is an American author.[1] He resides in San Diego and is known for his written works on skepticism and atheism.

Early life and education[edit]

Harrison has degrees in history and anthropology at the University of South Florida.[2] He was influenced towards skepticism by thinking about Erich von Däniken's book Chariots of the Gods?, which theorized that earth had been visited by aliens during antiquity.


From 1992 to 2010 Harrison wrote for Cayman Free Press in the Cayman Islands as a journalist, editor and photographer. As a journalist he has interviewed people such as Jane Goodall, Chuck Yeager, Edward Teller, Paul Tibbets and Armin Lehmann. From 2014–2015 he did medical writing for Kaiser Permanente.[3] He has a blog at Psychology Today named About Thinking.[4]

Starting with 50 reasons people give for believing in a god in 2008, Harrison has written five books on skeptical and philosophical issues.[5][6] The books are well known in skeptical circles and he has been widely interviewed in relation to his books by many different podcasts and websites.[7][8][9]

His books have received positive feedback from prominent scientists such as Neil deGrasse Tyson, Seth Shostak, and Donald Johanson.[10]


Harrison was a recipient of the World Health Organization Award for Health Reporting in 1997 and the Commonwealth Media Award for Excellence in Journalism in 1994.[11]
