whenever there is discussion about statistics role in science (sometimes even going as far as crossing into how science is statistics) i always remember this:
More revealing than the fraud allegations is the next section discussing the way results had pressure from his and other experiments' results for years, delaying our arrival at a more precise measurement. It reads as though it wasn't so much malice as it was self-doubt that lead to the scientists' actions.
