NO.PZ2022052301000005

问题如下:

Philly’s investment committee also met with their research analyst that covers the computer hardware industry to discuss the potential purchase of LTop Computers, a leading manufacturer of personal computer and tablets. Philly’s research analyst presented his investment recommendation and upgraded his rating on the stock to buy from hold given LTop’s new product introductions and an improved earnings outlook. During the discussion, committee chair Jackson Burke commented that he had suffered a major loss in LTop stock in the past so he would not be able to support buying the stock regardless of the improved outlook. There was little further discussion and the remaining committee members supported Burke’s view.

What behavioral bias most likely influenced the investment committee members to decide against the purchase of LTop stock?

选项:

A.

Loss Aversion

B.

Overconfidence

C.

Social Proof

解释:

Burke’s comment that he had suffered a major loss in LTop stock in the past and because of that experience he would not be able to support buying the stock regardless of the improved outlook and analyst upgrade unduly influenced the other committee members. The committee member’s actions demonstrated Social Proof, they wrongly endorsed the Investment Committee Chair’s judgement and they may not have been fully aware they were doing so.

嗨,爱思考的PZer你好:


1

social proof bias 并不在咱们之前介绍的 cognitive errors 和 emotional bias 的框架中(请参考基础班讲义 P84)

因为 Reading 1 列出的,都是最常见的偏差

对于一些特定场景特定主体的偏差,就没有都穷举在列表里了

而且关于偏差的分类,其实也没有完全统一的框架,这只是原版书作者自己的一种观点

2

关于备考建议,案例背景如果提到投资决策委员会,一般情况下,考查概率最大的就是 social proof bias 了

所以该偏差的学习(以及 R2 介绍的其他并未出现在 R1 中的偏差),重点并不是归类,而是掌握好识别及克服方法即可哈
