The Psychology of the Throw: How to Read Your Opponent
Scientists from universities around the world have studied human behavior during Rock Paper Scissors competitions. Their findings have actually revealed several interesting behavioral patterns that gamers can make use of.
Typical Human Tendencies

The Loser's Shift: When players lose a round, they nearly never toss the very same move two times in a row. Instead, they typically shift to the move that would have beaten what simply defeated them. For example, if Player A throws Rock and beats Player B's Scissors, Player B is statistically likely to toss Rock in the next round (because Rock beats Scissors). The Winner's Stays: Conversely, when gamers win a round, they tend to stick with the winning relocation.
Core Strategies for Success
