Svenson (2011) showed that choices of one of two alternative productivity increases to save production resources (e.g., man-months) were biased. Judgments of resource savings following a speed increase from a low production speed line were underestimated and following an increase of a high...

Subjects who judged speed in a driving scenario overestimated how fast they could decelerate when speeding compared to when keeping within the speed limit (Svenson, 2009). The purpose of the present studies were to replicate studies conducted in Europe with subjects in the U.S., to study the...

In an experimental simulation employing 123 undergraduates the effect of different travel modes on satisfaction with travel, mood after the day traveled, and satisfaction with the day as a whole were assessed for the work commute by car or bus. Car was rated higher than bus on satisfaction with...

Participants decided whom of two patients to prioritize for surgery in three studies. The factual quantitative information about the patients (e.g., probability of surviving surgery) was given in vignette form with case descriptions on Visual Analogue Scales --- VAS's. Differentiation and...

When people judge the time that can be saved by increasing speed they make systematic errors. This was called the time-saving bias by Svenson (2008) which describes that time savings following speed increases of high speeds are overestimated relative to time savings following increases of low...

Hazard management of the risks of human injury and death related to the automobile are described and exemplified by the Swedish car manufacturer Volvo. The study presents the Volvo units engaged in accident hazard management and their roles in the elaborate system of feedbacks (information,...
