Scientist in China a just figured the method behind the madness of playing rock, paper, scissors. Here is the psychology behind playing the game.

1. When a person wins with one of the three they are most likely to choose that one again. For example, if they beat you with rock, it is most likely they will go with rock again.

2. If they are the person that lost the match they are most likely to go with what beat them.

Studies say the switch is a conditional response, which means we do it instinctively, we are not actually picking it randomly.

Remember these tricks the next time you are in a rock, paper, scissors battle.
