The method

Update beliefs with evidence

A decision should change when its underlying evidence changes.

When to use it

  • Conclusions were formed under uncertainty.

Ask yourself

  • Everyone likes this direction. Do we still need a test?

Put it into action

  • Write down what would change the team's mind, make the assumption falsifiable, and set an experiment and review date.

Keep these limits in mind

  • Skepticism should improve decisions, not postpone them indefinitely.
