In a study released in September, researchers at Baylor University found that adherence to "traditional . . . religion greatly decreases credulity, as measured by beliefs in such things as dreams, Bigfoot, UFOs, haunted houses, communicating with the dead, and astrology." By contrast, those who reject traditional religion - "self-identified theological liberals and the irreligious" - are "far more likely" to believe in superstition and the occult. Or other nonsense: Maher, for example, claims that aspirin is lethal, doubts that the Salk vaccine eradicated polio, and has praised the horse that threw Christopher Reeve.
