Rock-paper-scissors is a game played all around the world. As kids, we have relied on it to settle disagreements with friends—from which channel to watch to who gets to eat the last ice cream—all because we think the results are completely
random
.
But are they?
Wang Zhijian, PhD, a professor at Zhejiang University, believes that there is a regulation behind this simple game. So, he gathered 360 students, divided them into groups of six and had each group play 300 rounds of rock-paper-scissors, reported USA Today.
After the first results, Wang thought he was wrong, because players chose each of the three moves about one-third of the time, suggesting that the game is random after all. However, Wang later noticed a surprising regulation of behavior in the data.
When players won a round, they usually stuck to the same choice. But when they lost, they tended to change to a more powerful move. For example, if Player A had just thrown down scissors to beat Player B' s paper, Player A was more likely to throw down scissors again while Player B was likely to choose rock, since rock beats scissors.
According to Wang, this might be a function that is called "conditional response". So, for the next step of his study, as he told BBC, Wang plans to do some research about how human brains make quick decisions when competing.
Now that you' ve learned how to predict the moves of your opponent, you' 11 have an advantage next time you play rock-paper-scissors with your friends. But there is one problem: make sure they haven' t read about Wang' s study, or your advantage will disappear.
