Day 19 / 100 · Critical thinking · Reasoning out loud

Show your working.

Conclusions alone can't be checked. When people share how they got there, others can spot the flaw, or learn the method.

The assumption

What I'm Taking As True

“I'm assuming traffic stays flat.”

  • Makes the hidden visible
  • Easy for others to challenge

The confidence

How Sure I Am

“About 70% on this.”

  • Invites the right scrutiny
  • Stops false certainty spreading

The trigger

What Would Change My Mind

“If p95 goes over 400ms, I'd rethink.”

  • Turns a view into a test
  • Makes updating easy, not a loss

Conclusions persuade. Reasoning teaches.
