An argument map is a visual representation of the structure of an argument in informal logic. It includes the components of an argument such as a main contention, premises, co-premises, objections, rebuttals and lemmas. Typically an argument map is a “box and arrow” diagram with boxes corresponding to propositions and arrows corresponding to relationships such as evidential support. Argument mapping is often designed to support deliberation over issues, ideas and arguments in Wicked problems.
