Scientific rundown on decision making in lay terms by Rolf Dobelli (Switzerland)  5 Stars
November 30, 2009
Making the right decisions is seldom easy. Situations change and choices confound. Faulty perceptions and biases can block clear thinking and undermine the ability to weigh alternatives rationally. As U.S. Supreme Court Justice Benjamin N. Cardozo explained 90 years ago, "We may try to see things as objectively as we please. Nonetheless, we can never see them with any eyes except our own." This is the vexing paradox involved in making decisions: People who are in the process of deciding cannot always trust their own perceptions and thought processes. Psychologist Scott Plous, winner of numerous awards and honors, examines decision making in this rigorously scientific yet mostly accessible book, itself an award winner. getAbstract believes it will interest decision analysts, researchers, psychologists and strategists, as well as readers who want to know why they may make poor decisions and how to make better ones.

Are we rational decision makers? by A. Panda (Guadalajara, Mexico)  4 Stars
September 13, 2009
First we need to define what we understand under rational. Initially, researchers measured human rationality by analyzing the degree of "maximization" of utility (net wealth) of their decisions. Using this approach, we seemed not too "rational". Then they came up with a value function, defined in terms of gains and losses as deviations from a reference point and which incorporates decreasing returns. (For a deeper explanation read Origin of Wealth: Evolution, Complexity, and the Radical Remaking of Economics). This curve makes the loss segment steeper than the profit segment ("S-shaped curve"). When measured against this function we seemed a bit more rational. For me, this should come as no surprise since decision making was probably a bit more oriented at preserving our lives and escaping dangers (loss part of the function) than at obtaining food. It would not be too useful to be the best food gatherer if you succumbed to your enemies at the first opportunity. (This is probably my first "hindsight bias", which means that after knowing the outcome of a study, we tend to say that we knew it from the beginning).
Apparently we tend to "satisfice" not "optimize", which for me is obvious (second hindsight bias). I will try to explain why for me it should have been obvious: When choosing between two alternatives I think most people (like myself) will rely on some sort of intuition (what the author calls heuristics or rules of thumbs). These rules of thumbs will rely on past experience with special emphasis on experiences that are easily accesible to our memory because they had a great emotional impact on us (positive or negative), because they are frequent or because they are relatively recent. In several of the problems presented in this book, in order to "maximize" value, you need to multiply one probability with another or with several others to obtain the combined probability result of two or more events happening one after the other. In other problems, you need to add up the individual probabilities in order to obtain the probability of either one or the other event happening. Assuming that you knew the rules of how to state the problem in terms of probabilities and how to calculate the combined probabilities (which would be the case if you had learned it somehow), you would still need to calculate them (consciously or unconsciously) in order to take a decision. Many decisions need to be taken quickly and even if there is enough time, I do not think people usually do these calculations. If we need to "maximize value" in order to be considered rational and if in order to "maximize value", we need to perform these kind of complex calculations routinely, then I am sure we do not "maximize". We are rather "satisfied" with a fairly good decision and therefore we cannot be considered rational, according to the previous definition.
It would have been interesting to know the people's decisions if the experts had made the proper calculations for them and given them the expected value of each choice (considering the probabilities). I think that "rationality" would increase a bit, but not significantly, since some people believe they can "outperform" the odds (by special luck), while others try to avoid undesirable risks, even if the probabilities are very low (specially if the impact of the risk is big).
The book explains thoroughly how we deviate from what would be a "rational" decision making. Each of the 20 chapters presents research that exemplifies one or more biases like inconsistency, perception and memory biases, framing, intransitivity, neglecting base rates, attribution errors, social loafing, sunk costs and behavioral traps. The book makes quite clear that we do not decide in a "rational" way, but it does not explain the process we really use to take decisions. Finally, the book makes evident that we are not good at probability and statistical analysis, but it does not go into the detail of explaining the probability calculations we should have done, were we "rational decision makers". If you already know this kind of math or if you are not interested, then the book can be read without it, but as for myself, I would have liked an Appendix containing a deeper explanation of the calculations involved.
The book is very interesting and full of insights, but I need to say that I am glad that I bought a used one, since its price seems not too rational to me either.

A Wonderful Work by R. johnson (Kentucky) 5 Stars
November 21, 2008
This work by Scott Plous should not be taken lightly. Dr. Plous, indeed, reviews the literature, but he also puts the missing pieces to the puzzle together as you try to understand how we got to the point we are today in the Psychology of judgment and decision making. Without this comprehensive review, it is hard to put other books in context. Many books explore specific persuasion principles and the psychological aspects of decision making. The problem is, how to you put all of the pieces together to make sense of it all. Plous gives the big picture so you will have a place from which to view all the other articles and books you read. I read this book four times and tried to pick apart each paragraph to see how it could apply to influencing others. I promise you the pearls are there if read each page with the goal of understanding how it can be applied in the real world. This book was my top 2 of all time!

Loved it and will read it again. by Lev Virine (Calgary, AB, Canada) 5 Stars
January 23, 2008
I think it is probably the best book on decision-making psychology I read. This book is full of great insights and tips into the decision making. It gives a very well rounded overview of the many aspects of decision making: selective perception, memory, biases and heuristic, behavioral traps, etc. It is also one of the more easily read books on the very complex subject. It has a large number of relevant and easy to digest examples.

by Thomas Gilovich (Editor), Dale Griffin (Editor), Daniel Kahneman (Editor)
Judgment pervades human experience. Do I have a strong enough case to go to trial? Will the Fed change interest rates? Can I trust this person? This book examines how people answer such questions. How do people cope with the complexities of the world economy, the uncertain behavior of friends and adversaries, or their own changing tastes and personalities? When are people's judgments prone to bias, and what is responsible for their biases? This book compiles psychologists' best attempts...

| Choices, Values, and Frames
by Daniel Kahneman (Editor), Amos Tversky (Editor)
Choices, Values, and Frames presents an empirical and theoretical challenge to classical utility theory, offering prospect theory as an alternative framework. Extensions and applications to diverse economic phenomena and to studies of consumer behavior are discussed. The book also elaborates on framing effects and other demonstrations that preferences are constructed in context, and it develops new approaches to the standard view of choice-based utility. As with the classic 1982 volume,...
