We have all heard of experts who fail basic tests of sensory discrimination in their own field: wine snobs (自命不凡的人) who can’t tell red from white wine (though in blackened cups), or art critics who see deep meaning in random lines drawn by a computer. We delight in such stories since anyone claiming to be an authority is fair game. But what if we shine the spotlight on choices we make about everyday things Experts might be forgiven for being wrong about the limits of their skills as experts, but could we be forgiven for being wrong about the limits of our skills as experts on ourselves
We have been trying to answer this question using techniques from magic performances. Rather than playing tricks with alternatives presented to participants, we secretly altered the outcomes of their choices, and recorded how they react. For example, in an early study we showed our volunteers pairs of picture

I don’t know what to do about my mother. She is always criticizing me — the way I dress, the way I speak or look. I can’t even read a book without her interrupting me to ask what it’s about and tell me whether I should be reading it or not, and why.
