I know this all may seem like nitpicking, but it is important to how the DK effect is interpreted. The vast majority of people who bring it up seem to think that it applies only to dumb people and that it says dumb people think they are smarter than smart people. Neither of these things are true. Further – if you think it only applies to other people (which itself, ironically, is part of the DK effect) then you miss the core lesson and opportunity for self-improvement and critical thinking.
