Of course, if you’re a fallibilist you believe that it’s always possible that you’re making a mistake. It seems unnecessary to always add “unless I am mistaken,” because that hedge always applies.

In principle I agree with you, but in practice people really seem to forget this basic premise of science and jump right to the “that’s how it is,” stage. So I think it’s helpful to continually remind ourselves that this enterprise is a skeptical one.
