“A reliable way to make people believe in falsehoods is frequent repetition, because familiarity is not easily distinguished from truth. Authoritarian institutions and marketers have always known this fact.”

John F. Kennedy: &quot;Remarks on the 20th Anniversary of the Voice of America&quot; (26 February 1962) http://www.presidency.ucsb.edu/ws/index.php?pid=9075&amp;st=&amp;st1=&lt;!-- Online by Gerhard Peters and John T. Woolley, The American Presidency Project --&gt; <br class="br">1962 <br class="br">Context: We welcome the views of others. We seek a free flow of information across national boundaries and oceans, across iron curtains and stone walls. We are not afraid to entrust the American people with unpleasant facts, foreign ideas, alien philosophies, and competitive values. For a nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.
