Rock paper scissors is a classic game that has been played for centuries. The rules are simple: players make hand gestures to represent either a rock, a piece of paper or a pair of scissors. Rock crushes scissors, scissors cuts paper, and paper covers rock. The game has been enjoyed by people of all ages for lots of reasons. But what few people know is that there is a surprising science behind the rules of the game.

In fact, rock paper scissors is used by scientists as a way of studying social decision making. They use it because it is a game of pure chance, and people have no way of predicting what their opponent will do. This means that their actions are not influenced by any preconceived notions or biases. As a result, the game offers a fascinating glimpse into the way people make decisions.

One of the most surprising findings in the study of rock paper scissors is that people tend to think in a cyclical pattern. They subconsciously assume that if they make a certain move, their opponent is more likely to make a certain counter-move. For example, if you choose rock, your opponent is more likely to choose paper. This is called the “transitive property,” and it is a well-documented phenomenon in the study of social decision making.

Another interesting finding is that people tend to favor one move over the others. When researchers analyzed data from thousands of rock paper scissors games, they found that people choose rock more often than paper or scissors. This is known as the “rock bias,” and it suggests that people have an innate preference for the solid, immovable object over the other two options.

There are also cultural factors at play in the game. In some countries, rock paper scissors is known by a different name, and the rules may be slightly different. For example, in Japan, the game is called “janken,” and there are often additional hand gestures that players can make, such as a lizard or a spock. These variations reflect cultural differences in the way people think about decision making, strategy, and chance.

Overall, the study of rock paper scissors is a fascinating window into the way people make decisions and interact with each other. Whether you’re playing the game for fun or as part of a research experiment, it’s important to remember that the rules are not arbitrary, but based on deep-seated patterns in human thinking and behavior. So next time you play a game of rock paper scissors, think about the surprising science behind the rules, and you may just gain some insight into the way you make decisions in your own life.
