Theories that go counter to the facts of human nature are foredoomed.

Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome. And human beings evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other, yet to be discovered. [...] Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.” I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.
Stephen Jay Gould
From what can "ought" be derived. The most compelling answer is this: ethics must be somehow based on an appreciation of human nature - on a sense of what a human being is or might be, and on what a human being might want to have or want to be. If that is naturalism, then naturalism is no fallacy. No one could seriously deny that ethics is responsive to such facts about human nature. We may just disagree about where to look for the most compelling facts about human nature -n novels, in religious texts, in psychological experiments, in biological or anthropological investigations. The fallacy is not naturalism but, rather, any simple-minded attempt to rush from facts to values. In other words, the fallacy is greedy reductionism of values to facts, rather than reductionism considered more circumspectly, as the attempt to unify our world-view so that out ethical principles don't clash irrationally with the way the world is.
Daniel C. Dennett
Purpose of counter-intelligence action is to disrupt [Black Panther Party] and it is immaterial whether facts exist to substantiate the charge. If facts are present it aids in the success of the proposal but the Bureau feels … that disruption can be accomplished without facts to back it up.
J. Edgar Hoover
Theories without facts may be barren, but facts without theories are meaningless.
Kenneth Boulding
Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress.
