LESSON 2 · Math Hacks for Decisions

The Rule In Brief

When you face options one at a time and cannot go back, gut instinct and endless searching both fail. There is a better move:

  • Look at the first 37% of your options to learn what "good" looks like, then commit to the next one that beats them all
  • That 37% gives you the best possible odds of landing the single best option
  • It fits hiring, apartment hunting, and any real-time choice with no second chances

The payoff is simple: a clear stopping rule beats both snap decisions and analysis paralysis.
