Someone who is incapable of
understanding the difference between an actually factually documented occurrence and opinion, myth, urban legends and outright lies. May be applied to
conspiracy theorists, science deniers and religious
fundamentalists. This is the kind of person who will be certain that the drunk guy next to him at the bar knows some kind of great secret when thousands of witnesses, documented evidence and hours of video footage prove otherwise. Note that this should not apply to people in cases where a true difference of opinion may take place, such as political ideology or favorite sports teams, but only in cases where a person seems incapable of accepting massive amounts of empirical evidence.
