On : Daniel Kahneman , . . New Challenges to the Rationality Assumption "

This paper is a useful integration of research that Professor Kahneman has conducted with several co-authors. The phenomena of individual decisions is a source of nagging curiosity for many sciences, applications of sciences, and philosophy. What he has to say should be of great interest to a very large research community. In discussing his paper I will narrow the perspective to economics and to a lesser extent political science, in the hope of facilitating better and more complete understanding of the fundamental and important perspective that he and his co-authors bring to those particular sciences.
