NO.PZ2018101901000021

问题如下：

The halo effect, which may be evident in FMP’s assessments of a company with a history of high revenue growth, is a form of which behavioral bias?

选项：

A.

Endowment

B.

Representativeness

C.

Regret aversion

解释：

B is correct.

Representativeness refers to the tendency to adopt a view or forecast based on individual information or a small sample, as well to use simple classifications. The halo effect is an example of representativeness, because FMPs extend an overall favorable evaluation to an investment (e.g., a “good company”) based on one or few characteristics (e.g., a “visionary CEO”).

嗨，爱思考的PZer你好：


1.光环效应简单说就是自带滤镜，比如一家具有良好成长记录的公司，我们通常会给他一个超过他价值的更高的预期。

2.endowment bias是我们通常会对自己持有的或者继承的股票一个特殊的感情，觉得他一定是好的。

regret aversion bias是人们倾向于避免做决定，因为他们害怕这个决定会带来糟糕的结果。
