Scientists find a winning strategy for rock-paper-scissors. A new study applies statistics, probability, and psychology to RPS.

A group of researchers from Chinese universities have written a paper about the role of psychology in winning (or losing) at rock-paper-scissors. After studying how players change or keep their strategies during multiple-round sessions, they figured out a basic rule that people tend to play by that could potentially be exploited. The researchers took 360 students, broke them into groups of six, and had them play 300 rounds of rock-paper-scissors in random pairings. The students received small amounts of money each time they won a round. As they played, the researchers observed how the players rotated through the three play options as they won or lost.
