Spot the Fake Coin Flips

People faking random flips almost never write long streaks

Write down 100 coin flips that look random. A math teacher could glance at your list and tell you never touched a coin.

You'll find out

  • What gives a made-up list away
  • How long real coin streaks get
  • Why a coin is never “due”

Why it matters

Real chance is streaky. Knowing that helps you spot made-up data and keeps you from betting that luck is “due.”
