Final answer:
In discussions, majority opinion leads to more attitude change than minority opinion due to the reinforcement of shared group views, contributing to group polarization.
Step-by-step explanation:
In the context of informational influences on group polarization, majority opinion in discussion produces more attitude change than does minority opinion. This phenomenon is well-documented in social psychology and can be observed in various settings, from political debates to business meetings.
Group polarization refers to the tendency for a group to make decisions that are more extreme than the initial inclination of its members. When a group discusses an issue, the prevalent view tends to become more pronounced. This effect is exacerbated by informational social influence, which is when people conform because they see the group as a source of information or a correct perspective. A discussion dominated by the majority opinion provides more reinforcement of shared views and contributes to stronger group consensus, sometimes leading to more polarized viewpoints. On the other hand, minority opinion, unless exceptionally persuasive, typically has less impact on swaying the group's overall stance, creating less attitude change than the majority opinion.
