The first principle is that you must not fool yourself, and you are the easiest person to fool.
—Richard Feynman
What I am saying is that, in numerous areas that we call science, we have come to like our habitual ways, and our studies that can be continued indefinitely. We measure, we define, we compute, we analyze, but we do not exclude. And this is not the way to use our minds most effectively or to make the fastest progress in solving scientific questions.
—John Platt
