What evidence is there that the map is static? We make maps and the world transforms. Rivers become canyons; mountains become mole hills (pardon the rhetorical ring I could not resist). Given that all maps are approximations isn't it rational to moderate one's navigation with the occasional off course exploration to verify that not drastic changes have occurred in the geography?
And because I feel the analogy is pretty far removed at this point, what I mean by that, is that if we have charted a goal-orientation based on our map that puts us on a specific trajectory, would it not be beneficial to occasional abandon our goal-orientation to explore other trajectories for potentially new and more lucrative paths.
The evidence that the territory is static is called Physics. The laws does not change, and the elegant counterargument against anti-inductionism is that if induction didn't work our brains would stop working, because our brains depend on static laws.
There is no evidence whatsoever that the map is static. It should never be, you should always be prepared to update, there isn't a universal prior that lets you reason inductively about any universe.
