Contrary to conventional wisdom, people of all levels of education like to believe in "weird things," says Michael Shermer of the Skeptical Inquirer. Shermer wrote that people tend to seek or interpret evidence favorable to existing beliefs and ignore or misinterpret evidence unfavorable to those beliefs.
This is no more obvious than in the writings of "creationist scientists" who either reject or grossly misinterpret geological, biological and astronomical data to support their biblical-based belief in an 8,000 year-old universe.
This "confirmation bias" is in real science as well. The classic example is the 1903 discovery of "N-rays" a completely new form of radiation announced by Prosper-René Blondlot. At the time, dozens of other scientists confirmed the existence of N-rays in their own laboratories. But further tests showed that N-rays don't exist at all.
How could so many scientists be wrong? They deceived themselves into thinking they were seeing something with their instruments that in fact was not there. This came on the heels of Wilhelm Rontgen's discovery of X-rays and Paul Ulrich Villard's discovery of gamma rays in the early 1900s. Apparently there was a predisposition to expecting that other invisible forms of radiation must permeate the universe.
