问题如下：
Patel’s comment in his risk tolerance questionnaire regarding the Private Wealth Investment Committee fails to recognize which bias?
选项：
A.Social proof.
B.Confirmation bias.
C.Gambler’s fallacy.
解释：
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. Committee members may wrongly favor the judgment of others, often without being fully aware that they are doing so. 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. There is no evidence that this committee encourages private information.
备注：这道题出的不太好，原版书给的答案A。Patel“一旦知道investment committee支持了某项投资，他的风险容忍程度会显著提高”，这句话既反映的是confirmation bias。social proof和herding是同义词，羊群效应，是一种从众的行为。Gambler's fallacy是赌徒谬误，比如连续五次抛出硬币的正面，认为第六次抛出硬币反面的概率非常高，但事实上，抛出反面的概率仍为50%，Patel没有这样的表现。不用纠结选项。

老师：
1。可以翻译下题目吗？是说他最可能有的但是被他fail（忽视）了的bias吗？
- 题目中有依据话反应了confirmation bias，但是其他这个都没有出现，为什么不选B啊？
