Outcome to Mechanism

When a target is being mistaken for a plan, draw the shortest causal chain from intervention to outcome and mark the weakest link.

You've announced you're running a marathon in October, put it on the calendar, told friends, bought shoes. It feels like a plan. It's a target. The distance between "marathon in October" and today contains an entire unexamined causal chain, and confusing the destination for the route is why so many announced goals dissolve by month two.

Outcome to Mechanism is a 30-second exposure for exactly this cue: a target being mistaken for a plan. The procedure: draw the shortest plausible causal chain from your intervention to the outcome, then mark the weakest link. Yours might read: four runs a week, which builds weekly mileage, which builds a long-run progression to 20 miles, which produces race-day capability. Now interrogate each arrow and find the weak one. It's probably not fitness at all; it's "four runs a week" surviving your travel schedule and dark November-style mornings, or the injury risk hiding in the mileage ramp. The weakest link is where your plan actually lives, so reinforce it specifically: a treadmill fallback, a rest-week rule. It works when vague confidence is replaced by one named vulnerability with a countermeasure. The spec's warning: label unverified links as hypotheses. "Long runs produce race capability" is well-supported; your personal arrow from intention to consistency is a guess until tested.
