State of the Art on Behavioral Choice Theory, September 19, 2001
This review is from: Bounded Rationality: The Adaptive Toolbox (Hardcover)
Suppose we wanted to predict how an expert billiards player would hit a certain shot. We would measure the angles and distances, get the coefficients of elasticity of the balls and the bumpers, and we would solve a set of differential equations. But is that how the billiards player figures out what to do? Of course not! We don't know exactly what he would do, but if the authors of this book had their way, we'd give up on the differential equations (optimization theory) and find the "fast and frugal heuristic" actually used by the billiards player.
This book is the product of a conference of experts in the field. It includes wonderful contributions by the editors and their coworkers on how decisions are actually made, and argues persuasively that fast and frugal is almost as good as full optimization, and at much lower cost.
But the volume is a lot broader than that. It includes contributions on the role of emotions in decision-making (Dan Fessler), learning in animal societies (Keven Laland) and social insects (Thomas Seeley), and a lot of material on the role of culture in human societies (Boyd, Richerson, McCabe, Smith, Henrich, and others). This is important new material, very up to date.
Gigerenzter and Selten go to great lengths to cast aspersions on the old-fashioned "optimization subject to constraints" perspective, but their arguments are not persuasive. They make a category error: they maintain that models that use optimization assume that the agents the models describe use optimization. This is just silly. Just as the billiards player does not solve differential equations, decision-makers do not do complete optimization, even though we may use such models to describe their behavior.
The editors believe that optimization subject to constraints is dead in behavioral theory, but they're dead wrong. That's in fact what they are doing, but they prefer to call it "bounded rationality."
Finally, I should note that the work of Eduardo Zambrano (look up his home page) shows that the SEU (Subjective Expected Utility model---the enemy of all bounded rationalers) actually is behaviorally universal, in the sense that one can always find a set of Bayesian priors for which an observed set of behaviors is optimal.
But don't let these petty methodological issues get you down. The book is a great collection by the authors of major work in behavioral theory.

Human Rationality and Evolution, August 12, 2006
This edited volume is an important addition to the work on human decision-making under conditions of uncertainty, in which people use "rules of thumb" to produce cost-effective decisions that are not strictly "rational." From the psychological literature, the work of Kahneman and Tversky is well know (and has been rewarded with international recognition). However, they do not explicitly link such behavior (often referred to as "heuristics") to evolution and biology. And they tend to define these "rules of thumb" as rather poor guides to decision making.
The essays in this edited volume provide a different--and more optimistic picture--of such heuristics. The contributors provide evidence and logic to suggest that evolution has led to the development of decision making shortcuts that "work" reasonably well.
One can disagree with certain aspects of this work (they may be a bit harsh on Kahneman and Tversky and their peers; they may be overly optimistic about some of the heuristics that they mention). Nonetheless, this work is a wonderful introduction to a literature on how humans actually think and decide--rather than relying on abstract conceptualizations often prevalent in the social sciences, including the simplistic "rational choice" theory ascendant in several social science disciplines. This book represents a welcome corrective to such perspectives.

Cavil about the Editorial Review, March 26, 2009
It was not "about forty years ago" that Herbert Simon used "satisficing" and "bounded rationality" to discuss human decision making. He used these terms in 1947 in his book, Administrative Behavior. That's more than 60 years ago.
