35. Curse of Knowledge Bias
If a person is very well informed about some area of knowledge or some problem, he may perceive difficult things as simple. And such a person would have some difficulties understanding other people who are not so well-versed in the basic concepts of the field. And the person also may find it difficult to explain these ideas to others, because when he understands something well others will not understand it.
