Leonard Adelman’s research is oriented toward (1) understanding judgment and decision processes, and (2) designing and evaluating systems to support them. Regarding the former, Adelman has performed research to understand how people define (or “frame”) judgment and decision problems. He has shown, for example, that how people frame problems can significantly affect the type of decision options they generate and select; anchor them on an incorrect cause of the problem because it leads them to emphasize confirmatory instead of dis-confirmatory information; and result in order effects, where the same information presented in different ordered sequences can result in different decisions.
Regarding the latter, Adelman has been involved in designing prototype systems and training procedures to support accurate, robust framing and, more generally, judgment and decision making processes. He also has been involved in evaluating geospatial-tool prototypes developed by the Army to support tactical planning, and possible human-computer interface changes to the Army’s Patriot air defense system and the Air Force’s Airborne Warning and Control System (AWACS). In addition to publishing journal and conference papers and book chapters, Adelman has co-authored one book on cognitive systems engineering, and authored one book and co-authored another on evaluating decision support and knowledge-based systems.
