Eh, it's one of those "uncomfortable truths," that people ignore or reject. It's like saying cereal has insect parts in its ingredient list. It's not a conspiracy theory; it's a fact.
For anyone who rejects Midwit Theory, the idea behind the theory is that the unintelligent and the super intelligent are guided more by gut feelings than the average person. Gut feelings are the result of hundreds of millions of years of evolution. They're more valuable than an "expert" could ever be, especially in your day-to-day life. Regardless of the wider disparity in intelligence, the same conclusion can be found; only the level of analysis differs.
