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

• I’ve broken the problem into pieces but they keep bleeding into each other and I have a nagging fear I’ve left a whole chunk out entirely
• When I list my reasons they bleed into each other
• I’ve laid out thousands of possible combinations and now I’m drowning in them
• When two things fit together neatly in my head, I treat the whole package as more likely than either piece alone
• I treat every idea on my list as its own separate thing, judging each one solo, and it never occurs to me to mash two of them together

Practices that may help

1. Build branches that are MECE at every level
   Ensure each set of branches is mutually exclusive (no overlap) and collectively exhaustive (nothing important missing).
   Issue Tree Analysis
2. Group supporting ideas into mutually exclusive, collectively exhaustive buckets
   Organize your three to five supporting points so they don’t overlap and together cover the argument completely (MECE).
   The Minto Pyramid Principle
3. Filter the matrix with cross-consistency assessment
   Identify which value combinations are impossible or contradictory to reduce the space to viable solutions.
   Morphological Analysis, Made Practical
4. Test each component probability separately
   Before judging a joint claim, estimate each element on its own, then check whether the conjunction is lower.

5. Combine and build on others’ ideas

9. Model synergy: ask "what would a solution have to look like to address both?"
