The Structure of Heresthetical Power

This article considers manipulation of collective choice — in such environments, a potential alternative is powerful only to the degree that its introduction can affect the collective decision. Using the Banks set (Banks, 1985), we present and characterize alternatives that can, and those that can not, affect sophisticated collective decision-making. Along with offering two substantive findings about political manipulation and a link between our results and Riker's concept of heresthetic, we define a new tournament solution concept that refines the Banks set, which we refer to as the heresthetically stable set.
