Knowing you’re going to be wrong means you are prepared to learn and adapt. Simplicity leans toward easy adjustment. If I can learn one of my 5 assumptions/inputs was wrong in a basic calculation I adjust easily. If I spent months on monolithic mathematics that make no sense to the masses I might be less likely to make changes.
If I go in expecting to learn and without marriage to metrics I’m going to beat you to the finish. The problem more often than not is a pathological pursuit of premature perfection. Lack of patience will lead to performance placebo. Perceived progress through piss poor paradigms pushed through to protect the pretentious pontificators that paradoxically postpone the providence of proof.
