老师你好,视频中讲解的是prediction-overconfidence是对结果的过度自信,certainty-overconfidence是对概率的过度自信,这个和冲刺笔记上所述相反,请问以哪个为准?

同学你好,一切以原版书为准,以下是原版书原话:
Prediction overconfidence occurs when the confidence intervals that FMPs assign to their investment predictions are too narrow。因此prediction overconfidence就是对未来预测的置信区间太窄。
Certainty overconfidence occurs when the probabilities that FMPs assign to outcomes are too high because they are too certain of their judgments。他就是对未来判断太过于确定了,从而高估了事件发生的概率
冲刺笔记与原版书的表述并不冲突
