问题如下：

Which of Tang’s findings is not a typical consequence of self-control bias?

选项：

A.

Failure to explore other portfolio opportunities.

B.

Asset allocation imbalance problems in the portfolio.

C.

A higher risk profile in the portfolio due to pursuit of higher returns.

解释：

A is correct.

Failing to explore other opportunities is a demonstration of status quo bias, not self-control. Self-control bias occurs when individuals deviate from their long-term goals, in this case, the investment policy statement, due to a lack of self-discipline. Jordan is not adhering to the strategy which has been successful in the past. The consequences of self-control bias include accepting too much risk in the portfolio (C) and asset allocation imbalance problems (B) as Jordan attempts to generate higher returns.

a是对，但c说的是她为了追求高return，她持有这个头寸的原因是为了等mean revertion啊，并不是为了追求高return

嗨，从没放弃的小努力你好：


1

其实站在「出题人」角度，这道题就是想考查的是 self-control bias 的结果

所以三个选项中，有两个选项对应其结果；然后再编一个干扰项，对应到其他行为偏差的结果即可

正如解析所说，选项 A 对应的是并不是 self-control bias 的结果，而是 status quo bias 的结果，所以选 A

此时的选项，只是客观描述行为偏差的结果，并不是要和题干背景一一对应

2

选项 B 和选项 C 基本是改写原版书原文哈，也请参考：https://class.pzacademy.com/qa/84517
