Rock-paper-scissors, also known as RPS, is a game played by individuals where they use hand gestures to choose one of three options: rock, paper or scissors. The game is usually played to determine a winner in a contest or decide who will perform a certain task. Although it may seem like a simple game, it can provide insight into how social influence affects decision-making.

Social influence refers to the impact that the presence or actions of others has on an individual’s thoughts, feelings, and behaviors. In the case of RPS, social influence can have a significant impact on the decisions made by players. Many studies have been conducted to understand how social influence affects RPS decision-making, and the results have been quite interesting.

One study found that when participants played RPS against a computer, they chose each option (rock, paper, scissors) almost equally. However, when the same participants played against a human opponent, they were more likely to choose the option that their opponent had already chosen in the previous round. This phenomenon is known as the “win-stay, lose-shift” strategy, where individuals stick to their winning option and change to the other option after losing.

Another study found that when participants played RPS in a group setting, they tended to mimic the gestures of the other players. This behavior is referred to as “conformity,” where individuals adjust their behavior to match the group’s norms and expectations. The more people in the group, the greater the likelihood of conformity.

Social influence can also have a lasting impact on decision-making. In one study, participants were shown a video of a group of people playing RPS, where one player consistently chose “paper.” Later, when the same participants played RPS against a computer, they were more likely to choose “scissors” instead of “rock” because they had been influenced by the “paper” player in the video.

Understanding the effects of social influence on RPS decision-making is not only interesting from a psychological perspective but also has practical implications. For example, it can help us understand how group dynamics can affect decision-making in a variety of contexts, such as business, politics, and education.

Overall, social influence plays a significant role in RPS decision-making. Whether we are playing against a computer or a human opponent, in a group or alone, social influence has the power to shape our decisions. By understanding these effects, we can become more aware of how we make decisions and how we can work to minimize the impact of social influence.
