Common Counterfactual Belief of Rationality Subsumes Superrationality On Symmetric Games
arXiv:1707.01816
Abstract
This paper shows that, for symmetric games in normal form, strategy profiles that satisfy Hofstadter's Superrationality criterion also satisfy both of Halpern's and Pass's criteria under Common Counterfactual Belief of Rationality: minimax-rationalizability and individual rationality.
