The word "idiot" refers to a genetically incompetent human who is mentally inert on exposure to others - may have dampened senses and mental acuity when applied to any relatively simple task from long periods spent in a dark cave: the idiot's "natural habitat". Idiots tend to be ignorant of any metal and physical deficiency within themselves, simply because they do not want to believe it exists (even though it does, and they are aware of it). Mental deficiencies of others however, are overtly proclaimed by the idiots in order for them to separate themselves from habitual human tendencies, though they succumb to them more than they intend. They make no effort to rectify these though, as they view themselves in the best possible light.
