Abstract

There is a well-documented indication that several applications would benefit from the transparency afforded by argumentation to support decision-making where standard decision theory is not useful, e.g. in healthcare. However, to date, research on argumentation-based decision making has only been partially successful in realising its promise. In our view this is predominantly due to its lack of theoretical validation in the form of rationality properties and its disregard for the interplay between individual rationality and social good when used in collaborative settings. We discuss how to address these challenges for the promise of argumentation-based decision-making to be fully realised as a principled mechanism for transparent and rational decision-making.
