I have a theory that I.Q. has something to do with your subconscious mind and the higher your I.Q. is, the easier it is to access it. If you’ve ever taken an I.Q. test, then you can somewhat agree because there are many questions about patterns and your subconscious mind picks up on patterns. Plus, it can help with tests because your subconscious mind remembers details that your normal mind cant (confirmed by Mythbusters by means of hypnosis, but i want to be able to access it without the use of hypnosis). There are confirmations of people being able to do this, most being detectives and what not (and Jason Bourne).
