Q

What did Brauer et al. (2001) find on group polarisation?

A

Group discussions led to stronger polarisation of opinions:
- If the group initially held positive views, discussion made them more favourable.
- If the group initially held negative views, discussion made them more unfavourable.

The effect was stronger when the group was more homogeneous.

Discussion doesn’t necessarily lead to moderation - it often makes attitudes more extreme.

Q

Describe Isozaki (1985) findings on global polarisation in judgements?

After group discussion, participants’ individual opinions became more extreme in the direction they initially leaned.
- If they initially believed the defendant was guilty, they became even more certain of guilt.
- If they initially believed the defendant was innocent, they become even more convinced of innocence.
