Tilings and bussola for making decisions

Abstract

We introduce the yes–no decision model, where individuals can make the decision yes or no. We characterize the coherent and un-coherent strategies that are Nash equilibria. Each decision tiling indicates the way coherent and un-coherent Nash equilibria co-exist and change with the relative decision preferences of the individuals for the yes, or no, decision. There are 289 combinatorial classes of decision tilings, described by the decision Bussola, what shows the high complexity of making decision.
