A survey of scientists who are members of the American Association for the Advancement of Science, conducted by the Pew Research Center for the People & the Press in May and June 2009, finds that members of this group are, on the whole, much less religious than the general public.1 Indeed, the survey shows that scientists are roughly half as likely as the general public to believe in God or a higher power. According to the poll, just over half of scientists (51%) believe in some form of deity or higher power; specifically, 33% of scientists say they believe in God, while 18% believe in a universal spirit or higher power. By contrast, 95% of Americans believe in some form of deity or higher power, according to a survey of the general public conducted by the Pew Research Center in July 2006. Specifically, more than eight-in-ten Americans (83%) say they believe in God and 12% believe in a universal spirit or higher power. Finally, the poll of scientists finds that four-in-ten scientists (41%) say they do not believe in God or a higher power, while the poll of the public finds that only 4% of Americans share this view.
