From: Human cooperation with artificial agents varies across countries
People in Japan cooperate with AI agents as much as they do with humans, whereas Americans cooperate with AI agents less. (A) Half of the participants in the Trust game were assigned to the role of player one (choice between the solid and the hollow white star) and the other half to the role of player two (choice between the solid and the hollow black star). The numbers at the three possible outcomes of the game are payoffs to players one and two, respectively (1 point = ¥2). Participants in the Prisoner’s Dilemma game chose between the two options identified by rows. The numbers in each cell are payoffs to the participant and their co-player, respectively. (B) Participants’ cooperation rates when they faced a human (H) and AI co-player in Japan (dark columns) and the United States (light columns). Note that not all participants in the role of player two in the Trust game had an opportunity to make a choice (this was conditional on the first player’s decision in the game). Bars: mean ± 1 s.d.. *, ***: p < 0.05, p < 0.001 in Pearson’s chi square one-sided tests for difference in proportions. Below chart: the number of cooperative choices (n) and the total number of observed choices (N) in each treatment.
