''Here comes the critical part: Now realize that you are as ignorant as the average person is in every other area of knowledge in which you are not expert. The Dunning-Kruger effect is not just about dumb people not realizing how dumb they are. It is about basic human psychology and cognitive biases. Dunning-Kruger applies to everyone. In addition to the various aspects of critical thinking, self-assessment is a skill we can strive to develop specifically. But a good rule of thumb is to err on the side of humility. If you assume that you know relatively less than you think you do and that there is more knowledge than you are aware of, you will usually be correct.'' -The Skeptics' Guide to the Universe Steven Novella
