Always the loser, never the winner? Here are some tricks that might change your luck when playing Rock Paper Scissors.

Chinese scientists have just released a paper showing that it is somewhat possible to predict players’ moves in a game of rock paper scissors.

The scientists ran an experiment with 360 students playing games of 300 rounds of Rock Paper Scissors.

The experiment found that humans are, as the video above states, “predictably irrational” in the way they choose their strategies. This being noted the scientists developed two ways players can beat each other.

Take a look at the video for all the tricks, and next time you and your friends can’t agree on something, make sure you challenge them to a Rock Paper Scissors contest…
