Gigerenzer is one of the researchers of behavioral intuition responsible for the science behind Malcolm Gladwell's bestseller Blink. Gladwell showed how snap decisions often yield better results than careful analysis. Now, Gigerenzer explains why intuition is such a powerful decision-making tool. Drawing on a decade of research, Gigerenzer demonstrates that gut feelings are actually the result of unconscious mental processes--processes that apply rules of thumb that we've derived from our environment and prior experiences. The value of these rules lies precisely in their difference from rational analysis--they take into account only the most useful bits of information rather than attempting to evaluate all possible factors. By examining various decisions we make, Gigerenzer shows how gut feelings not only lead to good practical decisions, but also underlie the moral choices that make our society function.--From publisher description.… (més)

It was so nice to read a book written by a researcher instead of a book that quotes other research.

What I got out of the book:
Simple decision strategies often
- Are faster
- Have a higher accuracy rate
Than strategies that utilize more information.

Simple decision strategies work better than more complex strategies when there is more randomness or noise in the environment.

I enjoyed this book.

In all candor, the book was a bit too "wonky" for me. It's not that one must be an expert in neuroscience to glean some fascinating insights. But I do think the work could have been made more accessible if it included additional anecdotal material. It gets a bit dense and even feels somewhat redundant as a reader hits the midway point. Still, the author serves up some interesting perspectives. ( )

Ok some interesting insights. ( )

MUCH better than Gladwell's "Blink". "Blink" reads like a series of interesting case studies, but by the end of that book you still have no clue about how intuition truly works.

Gigerenzer, who is a scientist and has done much of the original research in this field (unlike Gladwell who is a science writer that tries to capture the public's imagination), relates in very clear and precise terms HOW some forms of intuition are thought to work at this time. ( )

A really good introduction into modern research on psychological heuristics. The book is based on three main ideas: 1) many of our decisions are based on fast and frugal rules of thumb (as opposed to exhaustive calculations); 2) these rules are successful because they confer evolutionary advantage (and for this same reason, they are not consciously accessible, i.e. they present themselves as 'gut feelings'); 3) their predictive power comes from the fact that by being simple they avoid overfitting the data. I found this book much better written than the average popular science book. In addition to being very clearly written and containing very well chosen entertaining examples, it surprised me with a couple of some really interesting analyses. The first one is an analysis of the one dimensional voter (chapter 8) where Gigerenzer shows experimentally how a) Left-Right linear ordering immediately induces a complete ordering of preferences b) issues that seem orthogonal to Left-Right distinctions very readily get mapped on the same axis by the amount of support that an issue receives from a candidate who already has a location on that axis. The second one is the analysis of 'split-brain' organizations, i.e. organizations that employ very robust heuristics for their decisions ('let's not get sued!') but then confabulate a completely independent set of principles to explain/justify their decisions.
