This article presents a new approach to understanding strategic decision mak-ing inspired by the mathematics of quantum theory. Empirical support for thisnew approach comes from five different puzzling findings from past work on theprisoner dilemma game including the disjunction effect, the interference of pre-dictions on actions in simultaneous and sequential games, question order effect,and the effects of cheap promises. Eight different quantum models are described,which purport to account for these puzzling findings. The competing models aresystematically compared with respect to their capability of accounting for the five empirical findings.
