Reverse the question to expose hidden assumptions
Restate the problem from the opposite direction to see what you assumed.
Why it works
Every problem statement smuggles in assumptions about who acts, what is fixed, and what counts as success. Reversing it ("how do I keep customers?" → "what makes customers leave?") changes the frame and makes those assumptions visible, because the inverted version asks for evidence the original never requested.
How to do it
- Write the problem as you currently frame it.
- Reverse the verb or the actor: turn "how to get X" into "what causes not-X".
- Note which assumptions only appear once you read the reversed version.
Evidence
Reframing as a route to insight is well established in problem-solving psychology — how a problem is represented strongly shapes which solutions become reachable. Inversion is one specific reframing move within that broader, studied phenomenon. (mechanistic)
Reframing’s effect on insight is studied broadly; "inversion" as the specific reframe is a heuristic application.

Common mistake
Reversing the words superficially without checking whether the reversal exposes a real hidden assumption — producing a clever-sounding restatement that changes nothing.

More practices for Inversion: Solve Problems Backward
- State the goal, then invert it
Ask "what would guarantee I fail at this?" before asking how to succeed.
- Optimize for avoiding stupidity, not brilliance
Munger: "It is remarkable how much long-term advantage people like us have gotten by trying to be consistently not stupid."
- Solve by subtraction
Ask what to remove before asking what to add.
- Define your disqualifiers in advance
Before evaluating options, decide what would automatically rule one out.
- Build an anti-goal checklist
Keep a running list of "what failure looks like" and review against it.
