ABSTRACT
Searching for ideas and inspiration for this discussion, I read the concluding chapters from a number of previous Carnegie-Mellon Cognition Symposia. It struck me that most discussants assumed one of two roles: Jeremiah or cheerleader. Like most dichotomies, this one is too simple; all of the Jeremiahs offered some words of praise, and all of the cheerleaders voiced some criticisms. Still, the labels convey the dominant tone of the articles.
