Try It Yourself

Want to feel an equilibrium? Play 20 rounds of Rock-Paper-Scissors against a friend the normal way, then 20 more where you let a coin or die pick your throw each time.

Watch what happens. Played normally, most of us leak patterns — we avoid repeating our last throw, or we mirror the other person without noticing. The dice version has no pattern to read. If your win rate climbs once you randomize, your instinct was quietly giving you away.
