How Group Discussion Intensifies Opinions

Group polarization is the strengthening of an original attitude after people discuss their views in a group. When a group starts out favoring a position, discussion often leads to an even stronger endorsement of that position. When a group starts out against a position, discussion can lead to stronger opposition instead.

When people socially interact in like-minded groups, their pre-existing beliefs and attitudes may be intensified.

For instance, in a student environmental club meeting, the members share their opinions. After the conversation, everyone walks away with reinforced views supporting their initial opinions, which unites the kindred spirits.
