That’s true, those points ignore the pragmatics of a social situation in which you use the phrase “I don’t know” or “There’s no evidence for that”. But if you put yourself in the shoes of the boss instead of the employee (in the example given in “I don’t know”), where even if you have “no information” you still have to make a decision, then remembering that you probably DO know something that can at least give you an indication of what to do, is useful.
The points are also useful when the discussion is with a rationalist.
