After the appearance of Alpha Zero, in two-player deterministic and perfect information game like Shogi and Go, AI stronger than human was invented. WereWolf Game has been regarded as the new theme of game study. The project named “Artificial Intelligence based Werewolf” has the ultimate goal: “Building an agent which can play werewolf with humans naturally”. Researchers make progress in developing werewolf AI, but it is still few that studies reveal how human plays werewolf. In this study, we pay attention to “Why are players deceived” in decision-making process. Concretely, we examined how human makes decision by showing participants similar stories which changed a part of remark a bit. As the result, we suggest the influence of cognitive biases on human by comparing the examples which the participants are deceived and those which are not. We found that human does not necessarily make rational decision while playing werewolf game and that he/she conducts decision-making under the influence of various forms of bias depending on the content of what they are focusing on.
