Carnegie Mellon News on Information Avoidance:
We live in an unprecedented "age of information," but we use very little of it. Dieters prefer not to look at the calories in their tasty desert, people at high risk for disease avoid screenings and people choose the news source that aligns with their political ideology. [...]
Despite the consequences, information avoidance isn't always a mistake or a reflection of a lazy mind.
"People do it for a reason," said Golman, assistant professor of social and decision sciences.
