The Atlantic [free link]: “Having so much information at our fingertips is useful but seductive, easily fooling us into thinking we know more than we do…The overconfidence of people laboring under the illusion of explanatory depth can lead to the spread of misinformation. As researchers have shown, when a person’s confidence is highest though their actual knowledge is low, they become very believable to others—despite not being reliable. And the more inaccurate people are—or perhaps the more they want to believe the validity of their perception—the more they tend to be swayed by their own underinformed overconfidence.”
