Which of the following is NOT a reason for the occurrence of group polarization?

Exposure to contradictory viewpoints

The correct answer is Option 4: Exposure to contradictory viewpoints.

Group polarization occurs when group discussion strengthens existing opinions and pushes members toward more extreme positions. Factors such as confirmation bias, desire for consensus, and influence of strong leaders can contribute to this process. However, exposure to contradictory or opposing viewpoints usually reduces polarization because it encourages reconsideration of beliefs and introduces balance in discussion.

Option 1: Confirmation bias in evaluating information. This contributes to group polarization because people tend to focus more on information that supports their existing beliefs and ignore opposing views. This strengthens the group’s original position.

Option 2: Seeking consensus within the group. This can encourage members to align with the dominant opinion of the group, which may intensify the overall viewpoint and contribute to polarization.

Option 3: Validation of one’s views by like-minded group members. This is directly related to group polarization. When individuals find that others share similar opinions, their beliefs become stronger and more extreme.
