In chapter 10 (“How to Be Wrong”), we saw how most people implicitly assume that their “map” of reality is supposed to be already correct. If they have to make any changes to it, that’s a sign that they messed up somewhere along the way. Scouts have the opposite assumption. We all start out with wildly incorrect maps, and over time, as we get more information, we make them somewhat more accurate. Revising your map is a sign you’re doing things right.
