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 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. It finds evidence that not only supports the scientific impotence model, but suggests that it could be contagious. Once a subject has decided that a given topic is off limits to science, they tend to start applying the same logic to other issues.
