什么是recallability trap ?和anchor是主要区别?

NO.PZ2022122601000046

问题如下:

Board member Harold Melson notes he recently read an article on psychological traps related to making accurate and unbiased forecasts. He asks O’Reilly to inform the board about the anchoring trap and the confirming evidence trap. O’Reilly offers the following explanation:

The anchoring trap is the tendency for forecasts to be overly influenced by the memory of catastrophic or dramatic past events that are anchored in a person’s memory. The confirming evidence trap is the bias that leads individuals to give greater weight to information that supports a preferred viewpoint than to evidence that contradicts it.”

Is O’Reilly’s explanation of the anchoring trap most likely correct? (2018 mock PM)

选项:

A.No, because the anchoring trap is the tendency for the mind to give a disproportionate weight to the first information it receives on a topic

B. Yes.

C.No, because the anchoring trap is the tendency to temper forecasts so that they do not appear extreme

解释:

Correct Answer: A

A is correct. O’Reilly’s explanation of the anchoring trap is incorrect. The anchoring trap is the tendency of the mind to give disproportionate weight to the first information it receives on a topic. Initial impressions, estimates, or data anchor subsequent thoughts and judgments.

B is incorrect. O’Reilly’s statement regarding the anchoring trap is incorrect. This is a description of the recallability trap.

C is incorrect. Although O’Reilly’s statement regarding the anchoring trap is incorrect, this is a description of the prudence trap.

中文解析:

A正确。奥莱利对锚定陷阱的解释是不正确的。锚定陷阱是指大脑倾向于给它收到的关于某个话题的第一个信息不成比例的权重。最初的印象、估计或数据决定了随后的想法和判断。

B不正确。奥莱利关于锚定陷阱的说法是不正确的。这是对可回忆性陷阱的描述。

C选项不正确。虽然奥莱利关于锚定陷阱的陈述是不正确的,但这是对谨慎陷阱的描述。

嗨,爱思考的PZer你好:


Hello,亲爱的同学~

recallability trap 是指大脑里印象最深的,最容易回忆起来的那个信息,会给予过多的权重。

anchor是指锚定在某一个数字上。例如以3元买入股票,就会锚定在3元的成本价上,后面做决策并不是可观的考虑股票的基本面情况,而是取决于是否能回本解套。

最大的区别就是,anchor必须有一个具体的,被锚定的数字(原版书原文是:initial default number)。而recallability trap并不需要有具体数字。


原版书给出的定义如下:这里availability bias就是recallability trap
