Remember these when the "news" media holds someone up as an authority or expert in their attempt to make you go along with the program, whatever that program is:

"Make three correct guesses consecutively and you will establish a reputation as an expert." -- Laurence J. Peter

"Weinberg's Corollary: An expert is someone who avoids the small mistakes while sweeping on to the grand fallacy."

"An expert is a man who has made all the mistakes, which can be made, in a very narrow field." -- Niels Bohr (1885-1962)" -- [Quoted in A.L. Mackay, _The Harvest of a Quiet Eye_]

"An expert is someone who knows more and more about less and less until they know nearly everything about next to nothing." -- Norman Dann, Ph.D Soc. Sci.
