Here's how to win at rock-paper-scissors
Most everyone has played rock-paper-scissors. The game is used to choose up sides, or see who goes first or determine who gets the last piece of cake.
Now a study finds that people actually fall into patterns. Led by researchers at Zhejiang University in China, the study recruited 360 students, who played 300 rounds of the game.
According to the study, people who won the first round were more likely to stick with the same action. Those who lost switched to the next action in a clockwise direction (rock switches to paper, paper switches to scissors, scissors switches to rock).
As a savvy player, you can use that knowledge to your advantage if you lose. For example, if your opponent beats your rock with paper, theyre likely to choose paper the next game, so you should go with scissors.
This follows the basic theory that humans tend to stick with a winning strategy, the MIT Technology Review reports. As a player, your best bet is to resist that urge and go for a completely random object each time.
Critical thinking challenge: What does this study say about human behavior? Do humans prefer variety or consistency?
