Mr. Rotem Guttman Improving Human Decision Making with AI Decision Support Systems The project will proceed along several semi-overlapping tracks. This parallelism is built in to the project plan in order to both maximize how much can be accomplished during the period of performance. As the purpose of a LENS project is to determine the merits of an approach and inform the development of larger research programs, our focus will be on establishing both the appropriate test apparatus, as well as a useful baseline of layman performance. Without such a baseline, it would be impossible to assess the effect that the domain experience of subject matter experts may cause.
