This preface summarises the first Workshop on Multidisciplinary Perspectives on Human-AI Team Trust (MULTITTRUST 2023), co-located with 2nd International Conference on Hybrid Human-Artificial Intelligence (HHAI 2023), held on June 26th 2023 in Munich, Germany.

With the increasing adoption of Artificial intelligence (AI) as a crucial component of business strategy, establishing trust between humans and AI teammates remains a key issue. The project “We are in this together” highlights current theories on trust in Human-AI teams (HAIT) and proposes a research model that integrates insights from Industrial and Organizational Psychology, Human Factors Engineering, Human-Computer Interaction, and Computer Science. The proposed model suggests that in HAIT, trust involves multiple actors and is critical for team success. We present three main propositions for understanding trust in HAIT collaboration, focused on trustworthiness and trustworthiness reactions in interpersonal relationships between humans and AI teammates. We further suggest that individual, technological, and environmental factors impact trust relationships in HAIT. The project aims to contribute in developing effective HAIT by proposing a research model of trust in HAIT.
