Research has shown that people are capable of usingtheory of mind, which is the ability to reason about and understand the mental state of others. This study intends to find out if people make use of this ability in decision making while playing games, or if they use a different strategy. The game that was chosen is the Stag-Hunt game, in which a player needs to cooperate with an AI opponent to gain the maximum amount of points. We set up an experiment in which fifteen participants each played 320 rounds of the Stag-Hunt game, where the strategy of their opponent changed every ten rounds. We discovered that the participants do not show significant signs of the use of theory mind, in fact, theory of mind was used least frequently across all of the participants. However, the competitive and opportunistic strategies that the opponents in the game used were abundantly used by the participants as well. From these results we can conclude that participants are less likely to use theory of mind in games, as opposed to simpler strategies that only consider the current game state and not the belief state of their opponent.
