5 Claude prompts that apply Munger's inversion to map every way your goal fails
thisdudelikesAI · x · 2026-10-30
A thread of 5 copy-paste Claude prompts built on Charlie Munger's "Invert, always invert" method, designed to expose failure paths before you act:
- The Failure Map: Claude plays a ruthless strategist, listing 15+ realistic failure paths, sorting them into controllable/uncontrollable/personal-weakness buckets, scoring each by likelihood × damage, and surfacing the top 5 risks with early warning signs.
- The Guaranteed Misery Plan: Claude writes a step-by-step plan guaranteed to make you fail, quotes your own context as evidence of which steps you're already doing, then flips each into an Always/Never rule.
- The Hidden Assumption Killer: Claude reviews your plan as a skeptical investor, surfacing stated and hidden assumptions, rating confidence, failure impact, and earliest warning signs, then designing cheap <7-day tests for the 3 most damaging assumptions.
- The Daily Habit Autopsy: a pre-mortem set 3 years in the future, tracing your failure back to specific daily habits, ranking them by annual hidden cost, and proposing the smallest change that removes most of the risk.
The shared trick: make the model play an inverted role (failure planner / skeptical investor) against your real situation, which is harder to self-deceive than positive planning.
