Glomarization is good, but sometimes we can’t use it because others don’t understand the principle of Glomarization, or because you have too many counterfactual selves, and some of them won’t like just telling the truth. Therefore, when you are asked about Jews in the attic, it is acceptable to lie, but when you are asked if you would lie about Jews in the attic, you must ALWAYS tell the truth. So meta honesty is just a way to use glomarization as often as you want.
Let me reformulate this essay in one paragraph:
