Computerized aids may be used to support decision-making in a variety of complex, dynamic arenas. Of interest in these systems is the extent to which operators utilize and trust such systems, particularly under conditions of potential failure. A theoretical framework to describe potential factors affecting these issues, and an experiment to investigate the role of failure cause on trust and system utilization, are described. Results provide some support for factors in the theoretical framework, and also demonstrated the use of an empirically developed trust scale.
