The following is from an article on Ars Technica: 'It's hardly a secret that large segments of the population choose not to accept scientific data because it conflicts with their predefined beliefs: economic, political, religious, or otherwise. But many studies have indicated that these same people aren't happy with viewing themselves as anti-science, which can create a state of cognitive dissonance. That has left psychologists pondering the methods that these people use to rationalize the conflict. A study published in the Journal of Applied Social Psychology [abstract here] takes a look at one of these methods, which the authors term "scientific impotence" — the decision that science can't actually address the issue at hand properly.' The study found that 'regardless of whether the information presented confirmed or contradicted [the subjects'] existing beliefs, all of them came away from the reading with their beliefs strengthened."
