Recent improvements in information technologies have led to the creation and advancement of numerous interfaces or visual displays. However, not all innovations in visual representations optimize their users’ decisional performance. This research examines whether granting users discretion improves their decisional accuracy and expedites their decision making, as well as reduces their stress and mental workload. In addition, the current study utilizes an extensive, relatively stable construct in cognitive psychology – ambiguity tolerance – to represent individuals’ openness to complexities and investigates the impacts on those decisional outcomes. The mixed results yield implications for future studies.
