Abstract: This paper describes the phenomenon of user speed-accuracy trade-off in decision making in time and safety critical domains. We have observed such a behavior in two simulator studies, using the example of a takeover request (TOR) in a driving simulator and a search and collect task in an Industry 4.0 virtual reality (VR) environment. In both studies, some participants were observed trading decision accuracy for reaction speed, ignoring obvious visual cues, resulting in a failure of the task, which could have been prevented. The paper describes the phenomena and raises but does not yet solve the question, how to react to this behavior, either by adapting the process of Human Systems Integration, or by adapting the design e.g., with additional escalation patterns of a co-system.
