关于A

  1. CFA I
  2. Portfolio

NO.PZ2018101901000017

问题如下：

Jun Park, CFA, works at a hedge fund. Most of Park’s colleagues are also CFA charterholders. At an event with recent university graduates, Park comments, “Most CFA charterholders work at hedge funds.” Park’s remark exhibits which behavioral bias?

选项：

A.

Availability

B.

Conservatism

C.

Framing

解释：

A is correct.

Park is extrapolating his observation based on a narrow range of experience (working at a hedge fund that employs many CFA charterholders) to the entire population of CFA charterholders. Using a narrow range of experience is a form of availability bias.

还是不理解为啥是A，Availability bias是指按照最熟悉的，最能想起来的做，题干怎么体现这一点呢

嗨，爱思考的PZer你好：


您说的很对availability bias是指按照最熟悉的，最能想起来的做，题目说了这个人在hedge fund工作，并且自己也是个CFA，而且Most of Park’s colleagues are also CFA charterholders. ，所以他才说Most CFA charterholders work at hedge funds.

这个题可以用排除法做，首先排除C，因为FRAMING是指言语上的误导，这里并不涉及。

其次是B可以排除，Conservatism 是保守，指不愿对新信息改变，题目这里没有涉及新信息的事。

所以只能选A
