摘要: Exchange of arguments in a discussion often makes individuals more radical about their initial opinion. This phenomenon is known as Group-induced Attitude Polarization. A byproduct it are bipolarization effects, where the distance between attitudes two groups increases after discussion. paper first attempt to analyse building blocks information exchange and update that induce polarization. I use Argumentation Frameworks tool for encoding agents debate relative given issue a. then adapt specific measure degree acceptability an opinion (Matt Toni 2008). Changes a, prior posterior exchange, serve here indicator finally show way transmit has decisive impact on polarization bipolarization.
