Applications of hybrid intelligence systems in which humans and machines collaborate must behave responsibly in order to promote synergy and prevent unwanted or even harmful effects. For instance, the agents in a hybrid intelligence system (both human and automated) should communicate in a correct and reliable way, they should be able to provide their reasons for having a belief or opinion, and they should be able to explain their actions in terms of the values they apply. The aim of this workshop is to collect research and research ideas aimed at designing responsible hybrid intelligence systems. The workshop is organized in connection with the HHAI 2023 conference on Hybrid Human-Artificial Intelligence.
