" There is no possible reply to these heads-I-win-and-tails-you-lose assertions, except to note that they would justify any policy on any subject anywhere, regardless of its empirically observed consequences. In short, no matter what happens, the vision of the anointed always succeeds, if not by the original criteria, then by criteria extemporized later—and if not by empirical criteria, then by criteria sufficiently subjective to escape even the possibility of refutation. Evidence becomes irrelevant. "

― Thomas Sowell , The Vision of the Anointed: Self-Congratulation as a Basis for Social Policy
