It is as simple as this GIF:



I, of course, did not come up with the idea of rational irrationality. It's borrowed from a book, How Markets Fail, by the New Yorker writer John Cassidy. The idea is this: What's rational for an individual is often irrational for the whole. So what's needed is something like a sense of the Lacanian big Other, not for the purpose of social control or consolation but the presentation (a mental map) of the larger and truer rationality, the social rationality. The GIF goes from ego to the big Other.
