Does Counter-Attitudinal Information Cause Backlash? Results from Three Large Survey Experiments
Sign Up to like & getrecommendations! Published in 2018 at "British Journal of Political Science"
DOI: 10.1017/s0007123418000327
Abstract: Abstract Several theoretical perspectives suggest that when individuals are exposed to counter-attitudinal evidence or arguments, their pre-existing opinions and beliefs are reinforced, resulting in a phenomenon sometimes known as ‘backlash’. This article formalizes the concept… read more here.
