聰明人都這樣！

You're smarter ！

You understand how much you don't know

了解自己的不足

The smartest folks are able to admit when they aren't familiar with a particular concept. As Jim Winer writes, intelligent people "are not afraid to say: 'I don't know.' If they don't know it, they can learn it".

最聰明的人能承認自己不熟悉某一概念。正如吉姆•維納所寫，聰明人“并不畏懼說‘我不懂’。如果他們不知道，他們可以學習”。

Winer's observation is backed up by a classic study by Justin Kruger and David Dunning, published in the Journal of Personality and Social Psychology, which found that the less intelligent you are, the more you overestimate your cognitive abilities.

維納觀察到的這一點得到了賈斯汀•克魯格和大衛(wèi)•鄧寧在《人格與社會心理學雜志》上發(fā)表的一篇經典論文的支持，該論文指出，智力水平越低的人，越會高估自己的認知能力。

In one experiment, for example, students who'd scored in the lowest quartile on a test adapted from the LSAT overestimated the number of questions they'd gotten right by nearly 50 percent. Meanwhile, those who'd scored in the top slightly underestimated how many questions they'd gotten right.

例如，在一個實驗中，學生參加了從法學院入學考試題改編而成的測試，成績最差的學生把自己答對的題數高估了50%。與此同時，那些成績最好的人略微低估了自己答對的題數。
