People are less receptive to new information when they are offended. That was one of the key findings of a 2013 study by communication scientists at the University of Wisconsin. Researchers tested the effect of “uncivil” reader comments appended to online articles — remarks like, “You must be dumb if you think X.””The results were both surprising and disturbing,” study co-authors Dominique Brossard and Dietram A. Scheufele wrote in a summary published by the New York Times. “Uncivil comments not only polarized readers, but they often changed a participant’s interpretation of the news story itself.”They called this phenomenon the “nasty effect.”
