People who have a high IQ will sometimes, in a weird way, have a low EQ because they just don't have that emotional circuitry. This may also explain, for example, if you're a smart person who's very logically oriented, you may notice that you have some deficits. Once you reach a conclusion internally and emotionally that I am a bad person, or I will never be successful in life, it will hijack your logical circuitry.
