关于BF的默写

老师好,我近期在对BF的所有bias进行默写,原版书上的定义有些语句我不是那么容易背得下来,但是我认为我的理解含义了,所以按照尽量背下来的内容和自己的理解,把这部分在主观题中,每道题的第一部分也就是bias的定义默写了一遍,请老师帮我看一下,这样的话,可以在这部分得满分吗?如果不行的话,该如何改成简单易记的短句?

感谢。

另外就是关于representative bias, Conservative bias & confirmation bias这三个bias的英文定义老是记混,理解倒是理解的,但是好像就是表达起来定义很像,尤其是最后两个,可以帮个忙怎么办么?

嗨,努力学习的PZer你好:


1)请老师帮我看一下,这样的话,可以在这部分得满分吗?如果不行的话,该如何改成简单易记的短句?

我看了同学写的每个偏差的改写,有两个注意事项哈

第一个,同学可能手误了,关于 Conservatism bias 和 Confirmation bias 的定义,写反了

第二个,关于 Regret aversion bias,建议增加表述 "avoid making decisions",因为同学写的只是表达了担忧,但是没有写出最关键的结果,就是避免决策

其他偏差的定义,同学的改写都没问题哈

2)另外就是关于representative bias, Conservative bias & confirmation bias这三个bias的英文定义老是记混,理解倒是理解的,但是好像就是表达起来定义很像,尤其是最后两个,可以帮个忙怎么办么?

其实这三个偏差,建议分成两组

第一组就是 Confirmation bias,确认偏差,这个偏差其实非常好理解

比如我觉得疫情三年,2023 年股市应该反弹大牛了,所以我去网上找资料信息,都会倾向于去找和我观点相同的信息,所有预测 2023 年股市仍然是熊市的观点,我都看不到

第二组就是 Representative bias 和 Conservatism bias

这组偏差,我们从基础班的编排(例题的题干背景是相同的,只是客户的偏差不同),到经典题收录的题目(两道考查这两个偏差的历年真题都有收录),都在反应协会出题的套路

两个偏差,都涉及 base information 和 new information

Representativeness 是重视 new information, 轻视 base information, 结果是采纳观点或预测时,几乎完全基于新信息

"Adopt a view or a forecast based almost exclusively on new information or a small sample."

Conservatism bias 是重视 base information,轻视 new information,保持或缓慢地更新一个观点或预测,即使有新的信息出现。

"Maintain or be slow to update a view or a forecast, even when presented with new information."

历年真题中,有两道题考查过: [2018-4-B](1.4) , [2017-5-A](1.2)

格式说明: [真题](经典题) 。例: [2018-4-B](1.4) ,即真题 2018 年第 4 题的 B 问,经典题 R1 的 1.4 题

建议同学先把这两道题做一下,解题思路可以听一下经典题老师的讲解,感觉一下协会对 representativeness 的考查

如果备考时间紧张,只听其中一道的讲解即可,另外一道的考法是一样的,只是换了案例背景
