Break it down to what's true.

First-principles thinking strips a problem back to what must be true, then rebuilds from there, rather than copying how it's always been done.

Question

Spot The Assumptions

“Why do we do it this way?”

  • List what everyone takes for granted
  • Keep asking why, up to five times

Break down

Find The Bedrock

“What can't change?”

  • Physics, law, real constraints
  • Separate these from habit and history

Rebuild

Design Fresh

“What's the simplest path now?”

  • Start from the fundamentals
  • Add back only what earns its place
