Steelman objections to your own plans

Before committing to a plan, state the strongest case against it in its most compelling form.

Why it works

The main failure mode of planning is motivated cognition: you unconsciously weight evidence toward the plan’s success and construct weak versions of objections that are easy to dismiss. Deliberately steelmanning your own plan’s critics — reconstructing the objection in the form a smart, fully informed critic would use — bypasses this by forcing the strongest-case threat into the center of attention before commitment.

How to do it

1. After drafting a plan, ask: "Who is most likely to object to this, and what is the single strongest form their objection could take?"
2. Write the steelman objection in a full paragraph without weakening language.
3. Ask: "If this objection is right, does the plan need to change?" If yes, revise. If no, record specifically why it fails.
4. Do this for the two or three objections that, if valid, would most damage the plan.

Evidence

Pre-mortem analysis (Klein) is the closest experimentally grounded analogue: imagining failure reduces overconfidence. Steelmanning objections is a direct application to the strongest-case threat rather than general failure scenarios. Direct evidence for this specific format is limited. (mechanistic)

The strength of the steelman depends on the quality of the planner’s knowledge of the potential critics’ actual strongest arguments — which requires genuine familiarity with the opposing perspective.

Common mistake

Writing a steelman that defeats itself — building in the refutation as part of the objection’s framing, so the "strongest" version is still designed to lose.
