问题如下：
A traditional risk tolerance questionnaire is most likely to be effective as a diagnostic tool for:
选项：
A.Patel.
B.Perez.
C.Johnson.
解释：
B is correct.
Perez exhibits primarily cognitive rather than emotional biases. Although risk tolerance questionnaires may fail for emotionally biased individuals and work best for institutional investors, they are generally effective for cognitive-based individuals.
老师能否讲解下这道题目，我每个主人公都看了看：
Perez的hindsight，framing bias属于cognitive，regret aversion属于emotional 。
Johnson的illusion of control 属于cognitive，overconfidence 属于emotional。
为什么选择perez，而不是johnson？怎么做出的这个判断？
