老师,R3例题3,这里提及的prudence bias是什么?以及题目里怎么体现了有这个bias的。印象中在BF里头也没学过呢?

同学,早上好。
Prudence bias reflects the tendency to temper forecasts so that they do not appear extreme or the tendency to be overly cautious in forecasting. In decision-making contexts, one may be too cautious when making decisions that could damage one’s career or reputation. This bias can be mitigated by conscious effort to identify plausible scenarios that would give rise to more extreme outcomes and to give greater weight to such scenarios in the forecast.
谨慎性偏差反映了一种倾向,即调整预测,使其不显得极端,或在预测时过于谨慎。在决策过程中,一个人在做出可能损害自己职业或声誉的决定时可能过于谨慎。这种偏见可以通过有意识地努力确定可能导致更极端结果的合理情景,并在预测中给予此类情景更大的权重来缓解。
该题因为业绩表现较好,但是并没有利用较好的业绩创造更多的收益,配置相对保守,因此有Prudence bias。
