The Effect of AI Teammate Ethicality on Trust Outcomes and Individual Performance in Human-AI Teams

Abstract

This study improves the understanding of trust in human-AI teams by investigating the relationship of AI teammate ethicality on individual outcomes of trust (i.e., monitoring, confidence, fear) in AI teammates and human teammates over time. Specifically, a synthetic task environment was built to support a three person team with two human teammate and one AI teammate (simulated by a confederate). The AI teammate performed either an ethical or unethical action in three missions and measures of trust in the human and AI teammates were taken after each mission. Results from the study revealed that unethical actions by the AT had a significant effect on nearly all of the outcomes of trust measured and that levels of trust were dynamic over time for both the AI and human teammates, with the AI teammate recovering trust to Mission 1 levels by Mission 3. AI ethicality was mostly unrelated to participants trust in their fellow human teammate but did decrease perceptions of fear, paranoia, and skepticism in them and trust in the human and AI teammate was not significantly related to individual performance outcomes, which both diverge from previous trust research in human-AI teams utilizing competency-based trust violations.
