Dale Launer"Trompe-l'œil (French for "deceive the voter", pronounced [tromp lœj]) is a political campaigning technique that uses simplistic ideas in the form of short, facile slogans delivered in the idiom of a cosmopolitan thug creating the illusion that complex problems have easy attainable solutions. Exceptionally appealing to low information voters and aficionados of gangster movies."
The perfect definition of crowd behavior (A Study of the Popular Mind) written by Gustav Le Bon in 1895.
