A
big lie is a
propaganda technique. The expression was coined by
Adolf Hitler, when he dictated his 1925 book
Mein Kampf, about the use of a lie so "colossal" that no one would believe that someone "could have the impudence to distort the
truth so infamously." Hitler asserted the technique was used by Jews to unfairly blame Germany's loss in
World War I on German Army officer
Erich Ludendorff.
