 The distinction between full rationality and less-than-full rationality is central to idealization. Though, as we will see, full rationality is elusive. To attribute reasons to citizens based on poor reasoning corrupts public justification. A theory of full rationality idealizes agents by giving parties flawless cognitive powers. (See Rawls (1971, 12) and Gauthier (1986, 234) for explicit attributions of full rationality to their agents.)
