Decision Making

Inversion

The Promise

Ask how to fail first, then refuse to do those things. The traps you avoid matter more than the moves you make.

How It Works

  • State the goal, then invert the question. Replace "how do I succeed at X?" with "what would guarantee I fail at X?" The inverted question is almost always easier to answer.
  • Run a premortem before commitment. Imagine the project has failed twelve months from now. Ask why. The reasons surface failure modes that forward planning skips.
  • Build the avoid-list before the do-list. The avoid-list is shorter, more durable, and more actionable than the do-list.

In Practice

Forward thinking is blind to its own traps; wanting a plan to work is exactly what hides its holes. Inverting the question routes around that filter. The failure modes it surfaces are typically few, well-known, and concrete. Avoiding them leaves a decision space where ordinary judgment is enough.
