In his 1983 book “The Whys of a Philosophical Scrivener,” skeptic and science writer Martin Gardner cited the decline of traditional religious belief among the better educated as one of the causes for an increase in pseudoscience, cults and superstition.
He referenced a 1980 study published in the magazine Skeptical Inquirer that showed irreligious college students to be by far the most likely to embrace paranormal beliefs, while born-again Christian college students were the least likely.
