People aren't computers. Human beings live in a real world of scarcity and constraint. Even though time and information may be scarce, human beings must make high-stakes decisions. Probability and logic offer models for the thought process of choosing between alternatives, but decision makers often do not have enough hours, data and skill to use these sophisticated approaches. Fortunately, some rough and ready cognitive shortcuts perform as well as or better than the most elaborately sophisticated models - at least in the real world context of limited information and time. Working with the ABC Research Group, authors Gerd Gigerenzer and Peter M. Todd explore some of those shortcuts, called "heuristics." They discuss in length and depth a series of experiments that demonstrate the value of heuristics. This is not light reading. It requires a level of comfort with academic style, mathematics and symbolic logic. Readers unfamiliar with cognition literature may find it a struggle - but we believes that those who persevere will find enough new insight to make the effort worthwhile.

I was fascinated of Gigerenzers research from the first time on I had heard a talk of him in the city of Göttingen. He spoke about heuristics that led to many quick and ugly decisions of human beings because they would not require much brain ressources. Before reading "Simple Heuristics" I was naive enough to doubt that one could fill a whole textbook with these ideas. Then I realized that Gigerenzer and his group have made a terrific job in developping their ideas into various different directions and discussing every aspect of that theory I could image.

Maybe the most important thing that Gigerenzer and coworkers have shown is the possibility that knowledge can be a hindrance: In an experiment they asked German and American students which city was bigger, San Diego or San Antonio. The Germans outperformed the Americans because they could use the heuristics of recognition: They only knew San Diego and knowing a city is positively correlated with its size. I have a degree in statistics and must admit that I have also learned something new about statistics with this book: Gigerenzers simulations show that simple rules like using the best predictor and dichonomize it can outperform the predictions of multiple regressions when data are sparse.

Some consider Gigerenzer as just an evolutionary psychologist, but he is much more than that. For instance, he has extended the famous experiments of Kahnemann and Tversky and found that people decide more rationally (in the traditional sense, not taking cognitive ressources into account) when information is presented adequatly to them.

Everybody who is interested in psychology should know how heuristics work e.g. in decision making. Gigerenzer's research tells us something about how we managed to develop simple rules that often lead to the right decisions. Hence, it adds something very important to our understanding of the very nature of us as human beings.

Highly interesting and valuable not only for those interested in research on judgement & decision making but also for everyone interested in the behavioral sciences.

However, for this price, the print quality is unacceptable.
