Does this sound like the set of challenges you might be facing?

  • When I try to brainstorm how to make this work I freeze up and self-censor every idea as not good enough
  • The order this goes in feels so natural I’ve never once questioned it, and I want to know what opens up if I just flip the whole thing
  • I’ve been chewing on the same question
  • I keep grinding to engineer the perfect outcome and getting nowhere, and it just occurred to me I’ve never once flipped it around and asked what would absolutely guarantee this blows up
  • I keep brainstorming ways to make this thing succeed and my mind just keeps agreeing with itself

Practices that may help

  1. Inversion: Solve Problems Backward
    Inversion is the mental model — popularized by Charlie Munger via the mathematician Carl Jacobi’s "invert, always invert" — of approaching a problem from its opposite end: instead of asking how to succeed, ask what would guarantee failure, then systematically avoid it. It is a reasoning heuristic, not a studied intervention, but it reliably surfaces risks and assumptions that forward thinking misses.
  2. Reverse brainstorm: solve the opposite problem first
    Ask "How would we guarantee the worst possible outcome?" — then invert every answer.

  3. Reverse and Rearrange
    Ask: what if the sequence were inverted, the roles were swapped, or the normal order were reversed?

  4. Reverse the question to expose hidden assumptions
    Restate the problem from the opposite direction to see what you assumed.

  5. Use inversion as the first model in every problem
    Before solving a problem, ask what would guarantee failure — then avoid those things.

  6. State the goal, then invert it
    Ask "what would guarantee I fail at this?" before asking how to succeed.

  7. Reverse the problem to break fixation
    Ask the opposite question ("How could we make this worse?") to escape the constraints of the original framing.

  8. Solve by subtraction
    Ask what to remove before asking what to add.

  9. Study a fully worked example before attempting a new problem type
    Read through a completely solved example and understand each step before you try to solve anything yourself.

  10. Work backwards from what the learner needs to do
    Start with the decision or action the learner must take, then trace back only to the knowledge that serves it.
