A Reexamination of the Mediating Effect of Trust among Alarm Systems' Characteristics and Human Compliance and Reliance

Abstract

The most widely accepted view regarding the relationship among the characteristics of alarm systems and human compliance with and reliance on such systems is that trust plays a critical mediating effect. Researchers have promoted this contention based on theoretical and empirical evidence. However, there are some limitations associated with the prior empirical work that researchers have used to support this contention. The purpose of this research was to present an approach that more adequately assesses the potential mediating effect of trust among systems' characteristics and human compliance and reliance by establishing temporal precedence in the measurement of trust, compliance, and reliance. Contrary to previous theory and empirical findings, the preliminary results from this approach suggest that trust does not serve as a mediating factor. These findings seem to suggest that although trust is related to human compliance and reliance, it is simply a result of systems' characteristics that may or may not have differential effects on human-automation interaction.
