...people occasionally need to settle on a policy or need to decide whether a policy is better complied with or avoided?

One example would be the policy not to talk about politics. Authoritarian regimes usually employ that policy, most just fail to frame it as rationality.

No. But it is significantly more avoidable than commonly thought, and should largely be avoided for the first 3 years of hardcore rationality training. Or so the rules go in my should world.

Drawing a map of the territory is disjunctively impossible, coming up with a halfway sane policy based thereon is conjunctively impossible. Metaphorically.
