  Lisa Bortolotti reviews Adaptive Thinking: Rationality in the Real World by Gerd Gigerenzer
Gigerenzer wants to develop an alternative view of human rationality and scientific methodology that is sensitive to the important relation between human agents and the natural and social environment in which they operate.
According to Gigerenzer, we manage to make choices and solve problems by adopting some simple heuristics that fit the structure of the environment in which we live and the kind of choice or task with which we are faced.
Gigerenzer is not alone in urging us to take seriously the adaptive nature of human reasoning, but he is one of the few who has the courage to envisage an entire new framework.

 Barnes & Noble.com - Books: Gut Feelings, by Gerd Gigerenzer, Hardcover
Gigerenzer's theories about the usefulness of mental shortcuts were a small but crucial element of Malcolm Gladwell's bestseller Blink,and that attention has provided the psychologist, who is the director of the Max Planck Institute for Human Development in Berlin, the opportunity to recast his academic research for a general audience.
Gigerenzer draws on his own research as well as that of other psychologists to show how even experts rely on intuition to shape their judgment, going so far as to ignore available data in order to make snap decisions.

 Earl Hunt reviews Adaptive Thinking: Rationality in the Real World by Gerd Gigerenzer
Gigerenzer concludes that when people are asked to judge “probabilities” in situations like these they rightly refuse to adopt a frequentist interpretation.
Although Gigerenzer’s main argument is with theories of decision making, at various places in his book he broadens the attack to include arguments about the very way that theories are generated in modern social sciences.
Gigerenzer (once again echoing many others) also objects to what he sees as the unvarying formalistic approach to thought that computer modeling is said to engender.

 Gerd Gigerenzer   (Site not responding. Last check: 2007-10-20)
Gerd Gigerenzer has worked in many areas, from the history of probability theory and statistical inference to deductive reasoning in social contexts, but is perhaps best known for his theoretical and empirical work on judgment under uncertainty, and for his recent focus on applying evolutionary perspectives to cognitive science and decision-making.
His theoretical analyses have led to a reevaluation of the traditional cognitive practice of defining human rationality as a strict adherence to existing normative theories drawn from mathematics and logic, especially when applied without an analysis of the structure of the domain to which they are applied.
The work Gigerenzer will be talking about on Wednesday goes well beyond the prior research that demonstrated that people are good at solving Bayesian reasoning problems when asked to reason about event frequencies.

 New Statesman - You've nothing to fear but fear itself
Gerd Gigerenzer is good on how the presentation of statistics can distort our perception of risk and increase unnecessary anxieties about everything from breast cancer to "wife-battering".
Gigerenzer is concerned about how we are bombarded with warnings based on relative rather than absolute risks.
Gigerenzer suggests that we do not understand percentage analysis because, as a result of our long evolutionary history, "our minds are adapted to natural frequencies", in the same way that "rats are able to 'count' up to about 16".

 Oliver Curry reviews Bounded Rationality: The Adaptive Toolbox edited by Gerd Gigerenzer and Reinhard Selten.
Enter Gerd Gigerenzer who, for the past decade, has been developing the biological model of 'reasoning' in the hope of weaning economists and others off the 'rational actor' model.
Gigerenzer (and co-editor Reinhard Selten) illustrate what they call the 'fast and frugal' approach to rationality with the following example.
Gigerenzer and his research group have successfully identified several of the major types of decision rules that organisms employ, shown that these decision rules work well on a range of problems, and demonstrated that 'real' people actually use these rules to make decisions (including the gaze heuristic).

 Short Takes - The Boston Globe
Gerd Gigerenzer, director of the Max Planck Institute for Human Development in Berlin, describes "how the mind adapts and economizes by relying on the unconscious, on rules of thumb, and on evolved capacities." He locates specific strategies that the unconscious mind uses to solve problems.
In short chapters, using vivid examples and ordinary language, Gigerenzer explains how an outfielder catches a fly ball not by complex calculations but by unconsciously adjusting his running speed so that the angle of his gaze at the ball remains constant.
After giving many memorable examples of intuitive intelligence, Gigerenzer concludes, "There are many good reasons to trust your gut." While this conclusion is useful, it is the specific examples that the mind (conscious and unconscious) will take away from this clever book.

 Ending the Rationality Wars   (Site not responding. Last check: 2007-10-20)
When applied to cognitive mechanisms, Gigerenzer's accuracy-based criterion for epistemic evaluation bears an intimate relationship to the reliabilist tradition in epistemology according to which (very roughly) a cognitive mechanism is rational just in case it tends to produce true beliefs and avoid producing false ones (Goldman 1986; Nozick 1993).
In contrast with psychologists in the heuristics and biases tradition, Gigerenzer has urged that probability theory ought to be given a frequentist interpretation according to which probabilities are construed as relative frequencies of events in one class to events in another.
Gigerenzer clearly thinks that this conclusion can be put to work in order to dismantle part of the evidential base for the claim that human judgments and reasoning mechanisms violate appropriate norms.

 Before Gladwell Blinked, This Guy Followed Gut | The New York Observer
Gerd Gigerenzer, a director of the Max Planck Institute in Berlin, maintains that gut feelings, partial ignorance and selective forgetting are more important in making rapid decisions than a wealth of information and rigorous logic.
