"Verbal Decision Analysis for Unstructured Problems" is a specialized book that addresses the challenges of decision-making in unstructured situations. The authors, Oleg I. Larichev and Helen M. Moshkovich, highlight the discrepancy between the formal models of decision theory and the informal thinking of decision-makers. Over the past two decades, they have recognized that an effective solution must consider both the structural properties of alternative formalisms and the cognitive demands they place on decision-makers. By simultaneously examining these two aspects, the risk is reduced that decision-makers will support models they do not fully understand. The book offers creative solutions that integrate insights from decision theory and cognitive psychology, thus making a valuable contribution to improving decision-making.
