While they previously had devised a theoretical answer to the question, an experiment by Zhijian Wang at Zhejiang University in China (PDF) that used real players has revealed an interesting wrinkle to the original theory.
In the experiment, Zhijian noticed that winning players tended to stick with their winning strategy, while losers tended to switch to the next strategy in the sequence of rock-paper-scissors, following what he calls "persistent cyclic flows".
While the Nash Equilibrium should be the best strategy in real life, Zhijian found a decidedly different pattern when he and some other researchers recruited 72 students to play the game. They divided the students into 12 groups of six players and had them each play 300 rounds of rock-paper-scissors against each other. Zhijian also added a payout in proportion to the number of victories.
人 们往往认为“纳什均衡原理”是现实生活中玩石头剪刀布的最佳策略，而王志坚和自己的研究伙伴挑选了72位学生进行试验，结果发现了一个与纳什均衡具有明显 差异的致胜模式。他们将这些学生分成12个组，每组6人，让每组的组员一对一玩300回合的石头剪刀布。王志坚还根据游戏获胜的几率对学生们支付奖金。
The pattern that Zhijian discovered - winners repeating their strategy and losers moving to the next strategy in the sequence - is called a ’conditional response’ in game theory. The researchers have theorised that the response may be hard-wired into the brain, a question they intend to investigate with further experiments.
