As we increasingly rely on automated systems to perform tasks, it becomes ever more important to understand the ways in which real operators will use these systems. Trust is a critical determinant of this use. Previous efforts to translate trust, typically an interpersonal human experience, into the domain of artificial cognition and inanimate objects, has met with mixed success. Existing scales tend to anthropomorphize systems and attribute intent to relatively simplistic decision processes. This anthropomorphization has led to operator dissatisfaction with these scales and, consequently, poor data quality. In…
