问题如下：
The committee, made up of five highly experienced investment professionals with extensive personal investment portfolios, meets weekly. the committee members have diverse backgrounds and contrasting personal investment styles. the committee chair insists that no opinions should be expressed until such time as the analysts presenting have made their investment case and given their investment recommendations. The chair also mandates that all presentations be made available to the committee well in advance of each meeting. At the most recent investment committee meeting, one of Arzac’s analysts, despite lacking confidence in his analysis, recommends a company he knows is held in the personal portfolios of the chair and other senior members of the committee.
What is the most likely criticism of Arzac’s investment committee? The committee:
选项：
A.chair may dictate decisions
is unlikely to reach group consensus
exhibits social proof bias
解释：
The analyst who presents at the committee appears to be influenced by the status and prior comments made by the members of the investment committee. He may have wrongly favored the judgment or endorsement of committee members, which is an example of social proof bias.
A is incorrect. Given that the committee chair insists each analyst presents and gives their opinions before committee members indicates he will unlikely dictate the investment decisions.
B is incorrect because the chair requires all presentations to be made available to the committee well in advance of any meeting. Allowing the committee members to form opinions independently prior to the meeting will likely give rise to active discussions with varying viewpoints. Having members of an investment committee with diverse backgrounds and different investment styles can be viewed favorably in that it can help prevent groupthink. It does not necessary indicate they will not be able to reach a consensus.
老师，social proof bias不是个人更容易follow集体的beliefs，看答案感觉chair会倾向相信每个专家，没有感觉到是group beliefs。
