问题如下：
Linda is a portfolio manager with excellent record of performance. She owes the success to her hard working and sensitive observation of capital market. However, recently her portfolio did not perform well and some investors have withdrawn their investments. In her meeting with her boss Jesse, she said, ‘The underperformance should not blame on me. It is the traders who did not execute my order soon enough to catch up with the market changes.'
Linda most likely has:
选项： loss-aversion
bias.
self-attribution bias.
C.illusion of knowledge bias.
解释：
B is correct.
考点：behavior bias的区分
解析：Self-attribution bias说的是把成功归功于自己，把失败归因于别人。 Linda正好体现了这一点， 业绩差的原因是trader太慢，业绩好的原因是自己工作努力、对市场观察敏感。
这道题和有一题，问linda least likely有什么bias的题干是一样的，只是问题不同，选项里也都有illusion knowledge和self attribution。问least likey的题，老师的解释是，illusion knowledge和self attribution都是over confidence，题干没有representtativeness所以选represent……。这个题问的是likely，那就要从illusion knowledge和self attribution中，选一个更加符合linda情况的。是吗？这种题，就像做ethics一样，用排除法？
