State the goal, then invert it

Ask "what would guarantee I fail at this?" before asking how to succeed.

Why it works

Forward goals recruit confirmation-friendly thinking: the brain generates reasons the plan will work and stops searching. Flipping the question to "how would this fail?" redirects the same generative machinery toward failure modes, which are usually more concrete and more actionable than vague success. You then simply avoid the list you just produced.

How to do it

1. Write the goal in one plain sentence.
2. Ask the opposite: "What would reliably cause this to fail completely?"
3. List every failure path you can name, however obvious.
4. Turn the top failure paths into things you will deliberately not do.

Evidence

Inversion is a reasoning heuristic, not a tested clinical technique. Its plausibility rests on how reframing a question changes which information the mind retrieves — negative framings surface different, often more concrete, considerations than positive ones. (mechanistic)

No controlled outcome studies test "inversion" by name; treat it as a thinking discipline, not a proven protocol.

Common mistake

Inverting once and stopping. People list two obvious failure modes and feel done; the value is in exhausting the non-obvious ones the forward view hid.
