Bridging the Divide or Intensifying the Conflict? How Disagreement Affects Strong Predilections about Sexual Minorities

This study draws on a sample of participants in online groups that discussed legalization of same-sex marriage, to examine whether exposure to perceived disagreement decreases-as the deliberative theorists hope-or rather increases-as the research on confirmation bias predicts-strongly held predilections. Overall, participants' views towards same-sex marriage and sexual minority rights remained largely unchanged after deliberating, regardless of the ideological composition of their groups. Consistent with the confirmation bias model, those who strongly opposed same-sex marriage and sexual minority rights prior to the discussions and who perceived that others disagreed with them became even more opposed, and this effect was not a short-term shift. Strong proponents, on the other hand, did not polarize in their views, but instead became slightly less favorable towards same-sex marriage and sexual minority rights as a result of disagreement. Implications of these findings for deliberation of contentious issues are discussed.
