An expression taken from an old, old joke that describes a persons failure to grasp the obvious or demonstrate such [intellectual] ineptitude as to illicit a comment of " How Do It Know?" The joke refers to a question posed to a scientist by a student ( or in variations IBM executive and employee, Republican and voter..ect...)"Sir in your opinion what is the worlds greatest invention?" asked a student. The scientist replied "The thermos bottle!" "Why?" asked the student, obviously confused. " Well" said the scientist, "it keeps cold drinks cold in the summer and hot drinks hot in the winter." holding up his thermos bottle in awe,"How do it know?"Also see [No Shit Sherlock], Duh and [George W Bush]
