Fail to recognize某种bias=有某种bias? Social proof强调群体认同，group think
A is correct. Social proof is a belief in which individuals are biased to follow the beliefs of a group. The structure of Garnier’s Private Wealth Investment Committee indicates that they may be susceptible to a social proof bias. The committee meets to discuss and debate each security and then votes on which will be approved. The process of reaching a consensus will usually narrow the range of views. If a group decision process does not encourage private information held by individual committee members to be shared fully with others before a decision is made, the decision may fail to combine the collective wisdom of the group.
