“One of the best ways to keep a great secret is to shout it.”
Edwin H. Land (1909–1991) American scientist and inventor
Address to Polaroid employees at Symphony Hall in Boston, Massachusetts (5 February 1960), as quoted in Insisting on the Impossible : The Life of Edwin Land (1998) by Victor K. McElheny, p. 7
Land was not the first to make such observations; in One Man in His Time (1922), p. 162, Ellen Glasgow has a character state:
Half the time when he is telling the truth, it sounds like a joke, and that keeps people from believing him. He says the best way to keep a secret is to shout it from the housetops; and I've heard him say things straight out that sounded so far fetched nobody would think he was in earnest. I was the only person who knew that he was speaking the truth.
