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

  • Whenever something isn’t working my instinct is always to add
  • I want to lay this recurring thought out and actually weigh it like a fair judge
  • My mind only ever collects the evidence that proves the worst version is true and quietly throws out everything that doesn’t fit
  • The thought just feels so obviously true that I accept it on the spot without ever checking it
  • I keep treating one piece of this as a given

  5. Substitute
    Ask: what component, material, person, process, or rule could be swapped for something different?

  6. 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.
  7. Consider the opposite before finalizing a judgment
    Deliberately generate the case for the conclusion you are not reaching.
    Motivated Reasoning
  8. Generate a balanced alternative thought
    Write a more accurate thought that incorporates all the evidence — not a positive spin, but the actual picture.
    The Thought Record: CBT’s Core Self-Examination Tool
  9. Generate solutions without premature evaluation
    List as many potential solutions as possible before judging any of them.
    Problem-Solving Therapy, Made Practical
  10. Combine and build on others’ ideas
    Treat every idea as a building block — the best ideas in a session are usually hybrids.
