Not just instrumental goals. If you believe that you should achieve something, it doesn’t automatically mean that you really should. Your belief is a fact about your brain, which is not always in good alignment with your values (even though it really tries).
When you notice that you want something (as a terminal goal), you are reflecting on the fact that your brain, probably the best value-estimating apparatus you’ve got, has calculated that pursuing this goal is good. It could be wrong, it’s your job now to figure out if it made an error in that judgment. Maybe you can find a way to improve on its reasoning process, compensating for a specific flaw and thus gaining access to a superior conclusion produced by the improved procedure (which is often ultimately the point of knowing how things work). (Or maybe you’ll even find an argument that makes taking into account what your own brain tells you in a given instance a bad idea.)

But where do values reside? How do you know that your belief did not correspond to your values?
Where does truth about arithmetic reside? How can you ever find out that you’ve miscalculated something? Apply similar principles to moral questions.
