问题如下：
Linda is a hedge fund manager with excellent record of performance. She owes the success to her team, which is full of experienced experts. Last year, her fund suffered a severe loss due to economic policy changes, but she believes the investment strategy is still successful.
The team usually has a meeting every Monday to discuss the fund and market situation. Linda refuses the team's advice about adjusting the portfolio, and tells them she believes the strategy is fine and the fund’s return will revert very soon.
Which one least supports that she shows illusion of control bias?
选项：
A.Her refuse of the team's analysis.
B.The regular team meeting.
C.Her thoughts on portfolio strategy and portfolio performance.
解释：
B is correct.
考点：illusion of control bias的表现
解析：Illusion of control bias 说的是人们觉得自己可以控制结果。尽管经济政策发生变化，Linda的基金业绩已经下滑，超出了她的控制，但她仍然坚持当前投资策略，反对团队的建议，是illusion of control的表现。
每周开一次会，说明Linda是愿意听别人的意见和反馈的，所以B选项正确。
想请问下illusion of control bias与overconfidence bias的区别？ 这道题中的人物是否能被认定为具有overconfidence bias?
