Very true. Ignore correlations, though, and you might get the same surprise Admiral Kimmel got, because sometimes correlation is all you get. Kimmel kept waiting for a friendly tap on the shoulder from good old Uncle Franklin. He never got it. People have written books about that ..... oh, and FDR was a 'Rat, too, just like Java Barry.
A lot of people don’t have street instincts. I am reminded of those who decided the best ploy was for the Titanic to go full-speed in the night.
