Why the Other Line Always Moves Faster

With three lines, yours is the fastest only a third of the time

You pick a checkout line, and the one next to you starts moving faster. Is the universe against you, or is it math?

You'll find out

  • How often your line should win
  • Why losing sticks in your mind
  • The setup that's fairer and faster

Why it matters

Stores, airports, call centers and websites all use the same math to keep you waiting less.
