I can follow a protocol — why does designing my own overwhelm me?

You follow protocols well. Give you the steps, you execute them, no hesitation. But hand you a blank page — design your own test, pick your own variable — and you stall. You call this overwhelm. Look again. It is something else. A protocol is someone else's judgment, already made for you. You only have to obey it. Designing your own experiment means deciding what matters, what to risk, and what to measure — and being wrong, in public, with no manual to blame. That is not a bigger version of following instructions. It is a different act entirely: judgment instead of compliance. You were not born knowing how to do this. No one was. Judgment is built the same way a muscle is — by small, repeated acts of choosing, not by waiting until the design feels obvious. Start smaller than you think you need to.
