Question

Discuss the reasons for 'Group Polarization' in decision-making processes.

Hint:

{Group Polarization} occurs when group discussions push members toward more extreme decisions. The two main reasons are:
1. {Informational Influence (Persuasive Arguments):} Hearing more arguments that support the initial view.
2. {Normative Influence (Social Comparison):} Wanting to fit in and be seen favorably by the group.

Answer 1

Step 1: Understanding the Question
This question asks for an explanation of the reasons behind the phenomenon of group polarization. The answer should first define what group polarization is and then discuss the primary psychological mechanisms that cause it to occur during group decision-making.
Step 2: Detailed Explanation
Group polarization is the tendency for a group's initial attitude or opinion to become more extreme after discussion among its members. If the group members initially lean towards a cautious decision, the group discussion will likely lead to an even more cautious final decision. Conversely, if they lean towards a risky decision, the group will likely end up making an even riskier one.
The main reasons for this phenomenon are:

Persuasive Arguments Theory (Informational Influence):
This explanation suggests that during a discussion, individuals are exposed to a pool of arguments. The direction of the group's initial leaning will determine the content of these arguments.

Members will hear more novel arguments that support their own initial position and fewer arguments that challenge it.

This exposure to new, persuasive information strengthens their original viewpoint, pushing them further in that direction. For example, in a group that is mildly against a policy, the discussion will mainly consist of anti-policy arguments, making each member more convinced of their negative stance.


Social Comparison Theory (Normative Influence):
This explanation focuses on people's desire to be perceived favorably by their peers. Before the discussion, individuals may believe their stance is stronger or more "correct" than that of others.

During the discussion, they learn about the opinions of others. If they find that others share their views, they may shift to a more extreme position to differentiate themselves and be seen as a strong, confident member of the group.

It's a process of "one-upping" each other to align with and even champion the perceived group norm.


Group Identity and Self-Categorization:
People may polarize their views to conform to the perceived prototype of their in-group.

When a group identity is salient, members may shift their opinions to be more in line with what they believe is the ideal or prototypical stance of their group, especially to distinguish their group from an out-group.
