"It is no coincidence, I am sure, that those who have the most to say about the Project are the ones who have had no direct contact with it. Which is similar to the attitude physicists have regarding gravitation or electrons — as opposed to that of the "well-informed" who read popular science. The "well-informed" think they know something about matters that the experts are reluctant to even to speak of. Information at second hand always gives an impression of tidiness, in contrast with the data at the scientist's disposal, full of gaps and uncertainties."
