Whistle-blowers are punished or even prosecuted, and people who question the prevailing deviant culture are routinely and efficiently marginalized, not promoted to decision-making positions.

For example, once U.S. officials had accepted the Orwellian “doublethink” that “targeted killings,” or “manhunts” as Defense Secretary Donald Rumsfeld called them, do not violate long-standing prohibitions against assassination, even a new administration could not walk that decision back without forcing a deviant culture to confront the wrong-headedness and illegality of its original decision.
