This study investigates human impressions of autonomous agents that refrain from action. The increasing frequency of human–agent interactions has increased the demand for cooperative human–agent behavior. In human communication, cooperative behavior is frequently regarded as refraining from action to consider the requirements or desires of others (referred to as enryo in Japanese). However, enryo behavior is rarely investigated in human–agent interaction experiments. Investigating how people react to an agent refraining from action and observing actions of the agents would advance the society toward coexistence of humans and autonomous agents. Here, we demonstrate that humans indeed perceive enryo demonstrations in refraining-from-action agents; moreover, this behavior renders an agent more anthropomorphic and likeable than a non-considerate agent. Enryo impressions are also associated with increased human proactivity, suggesting that enryo functions as a social cue that encourages initiative actions by humans. Therefore, incorporating enryo -like behavior in agents may enhance the smoothness and cooperativeness of human–agent interactions.
