The construct of state-level suspicion: a model and research agenda for automated and information technology (IT) contexts.

OBJECTIVE: The objective was to review and integrate available research about the construct of state-level suspicion as it appears in social science literatures and apply the resulting findings to information technology (IT) contexts. BACKGROUND: Although the human factors literature is replete with articles about trust (and distrust) in automation, there is little on the related, but distinct, construct of "suspicion" (in either automated or IT contexts). The construct of suspicion--its precise definition, theoretical correlates, and role in such applications--deserves further study. METHOD: Literatures that consider suspicion are reviewed and integrated. Literatures include communication, psychology, human factors, management, marketing, information technology, and brain/neurology. We first develop a generic model of state-level suspicion. Research propositions are then derived within IT contexts. RESULTS: Fundamental components of suspicion include (a) uncertainty, (b) increased cognitive processing (e.g., generation of alternative explanations for perceived discrepancies), and (c) perceptions of (mal)intent. State suspicion is defined as the simultaneous occurrence of these three components. Our analysis also suggests that trust inhibits suspicion, whereas distrust can be a catalyst of state-level suspicion. Based on a three-stage model of state-level suspicion, associated research propositions and questions are developed. These propositions and questions are intended to help guide future work on the measurement of suspicion (self-report and neurological), as well as the role of the construct of suspicion in models of decision making and detection of deception. CONCLUSION: The study of suspicion, including its correlates, antecedents, and consequences, is important. We hope that the social sciences will benefit from our integrated definition and model of state suspicion. The research propositions regarding suspicion in IT contexts should motivate substantial research in human factors and related fields.

Forgotten but not gone: an examination of fit between leader consideration and initiating structure needed and received.

We examined the effects of fit between leader consideration and initiating structure needed and received on employees' work-related attitudes (i.e., trust in the supervisor, job satisfaction, and affective commitment to the organization). Consistent with predictions that derive from the person-environment fit research tradition, results from Study 1 suggested that deficient amounts of both leadership behaviors were associated with unfavorable attitudinal outcomes. However, while excess levels of consideration were associated with favorable attitudinal outcomes, excess levels of initiating structure were associated with unfavorable attitudes, and for both forms of leadership, higher levels of absolute fit were associated with more favorable outcomes. Results from Study 2 suggested that attitudes generated by the fit between leadership needed and received influence employees' organizational citizenship behavior as reported by their supervisors. The relationship between consideration needed and received and subordinates' organizational citizenship behavior relating to individuals (OCBI) and organizational citizenship behavior relating to the organization itself (OCBO) was partially mediated by employees' trust in the supervisor, while the relationship between initiating structure needed and received and OCBI was fully mediated by trust in the supervisor, and for OCBO was partially mediated.

Trustworthiness and IT suspicion: an evaluation of the nomological network.

OBJECTIVE: The authors evaluated the validity of trust in automation and information technology (IT) suspicion by examining their factor structure and relationship with decision confidence. BACKGROUND: Research on trust has burgeoned, yet the dimensionality of trust remains elusive. Researchers suggest that trust is a unidimensional construct, whereas others believe it is multidimensional. Additionally, novel constructs,such as IT suspicion, have yet to be distinguished from trust in automation. Research is needed to examine the overlap between these constructs and to determine the dimensionality of trust in automation. METHOD: Participants (N = 72) engaged in a computer-based convoy scenario involving an automated decision aid. The aid fused real-time sensor data and provided route recommendations to participants who selected a route based on (a) a map with historical enemy information, (b) sensor inputs, and (c) automation suggestions. Measures for trust in automation and IT suspicion were administered after individuals interacted with the automation. RESULTS: Results indicated three orthogonal factors: trust, distrust, and IT suspicion. Each variable was explored as a predictor of decision confidence. Distrust and trust evidenced unique influences on decision confidence, albeit at different times. Higher distrust related to less confidence, whereas trust related to greater confidence. CONCLUSION: The current study found that trust in automation was best characterized by two orthogonal dimensions (trust and distrust). Both trust and distrust were found to be independent from IT suspicion,and both distrust and trust uniquely predicted decision confidence. APPLICATION: Researchers may consider using separate measures for trust and distrust in future studies.
