Final answer:
Group polarization is the phenomenon in which group discussion reinforces the group's prevailing attitudes, leading to stronger stances on a given viewpoint.
Step-by-step explanation:
The enhancement of a group's prevailing inclinations through group discussion is called group polarization. This phenomenon reflects the strengthening of the original group attitude after discussing views within the group. If a group is leaning towards a particular viewpoint, the process of discussion amongst the members often leads the group to adopt a stronger stance towards that viewpoint. This effect can further lead to groupthink, where members of the group suppress dissenting opinions to maintain group harmony and consensus.
Group polarization leads to more extreme decisions than those that individuals would make on their own, and it is an important concept to understand in the context of social dynamics and decision-making within groups.
