Human Computer Interaction


Significant research has shown the impact of trust (i.e., trusting beliefs) in information technology (IT) settings. Mostresearch has investigated trust between the consumer and the e-vendor. However, IT researchers have begun to investigateuser trust in the technology artifact itself (trust-in-technology). This research has measured trust using both interpersonaltrust variables (ability, benevolence, and integrity) and system-like trust variables (functionality, helpfulness, and reliability).Both measures seem to work. However, it is unclear when researchers should use interpersonal versus system-like trust-intechnologyconstructs. This study hypothesizes interpersonal trust will have a stronger influence on users’ outcomes whenthe technology is more human-like. By contrast, system-like trust will have a stronger influence when the technology is lesshuman-like. We validate this concept by measuring how both interpersonal and system-like trust predict user outcomes acrossthree technologies: Facebook (high humanness), a recommendation agent (medium humanness), and Microsoft Access (lowhumanness).
