壹苹派生活美语　剪刀石头布：历史与策略大揭密

　　On the surface, rock, paper, scissors appears to be a simple game of luck. However, a study shows that people can actually increase their chances of winning by employing some psychological strategies. First, use the “win-stay, lose-shift” principle to predict your opponents’ next move. If they play paper and win, they are likely to repeat the action in the next round. On the other hand, if they throw rock and lose, they will probably move to the next action in the sequence, which means they are going to play paper.

　　从表面上看，剪刀、石头、布似乎是一个简单的运气游戏。然而，一项研究表明，人们实际上可以透过采用一些心理策略来增加获胜的机会。首先，运用「赢就留，输就换」的原则来预测对手的下一步行动。如果他们出布赢了，他们很可能会在下一轮重复这个动作。另一方面，如果他们出石头输了，他们可能会按照顺序进行下一个动作，这意味著他们接下来会出布。
