Irrational Beliefs

Millions of Americans believe in conspiracy theories - including plenty of people who you might expect would be smart enough to know better. Despite mountains of scientific evidence to the contrary, at least 20% of Americans still believe in a link between vaccines and autism, and at least 37% think global warming is a hoax and believe astrology works. And still believe conspiracy theories like, the moon landings were faked, the government had advance warning of the 9/11 attacks
Intelligence doesn't seem to matter. Kary Mullis who won the Nobel Prize in chemistry for inventing PCR believes in astrology. Now, a study published online in the journal Personality and Individual Differences provides new insights into why so many of us believe in things that just arent true: In some cases, we simply want to believe.
Psychologists Thomas Stahl of the University of Illinois at Chicago and Jan-Willem van Proojien of the Vrije Universiteit Amsterdam measured the subjects in a study on the so-called Importance of Rationality Scale (IRS) and the Morality of Rationality Scale (MRS).
Whats most troubling and a little mystifying is the fact is that so many people in the studies score high on all of the rational and intellectual metrics and yet nonetheless subscribe to disproven theories. Thats the case in the real world too, where highly educated people traffic in conspiratorial nonsense that youd think theyd reject. In these cases, the study concluded, the reason may simply be that theyre investedemotionally, ideologicallyin believing the conspiracies, and they use their considerable cognitive skills to persuade themselves that whats untrue is actually true.
