To exorcise the demons of irrationality, turn to this rigorous—if overzealous—study of everyday logic. Cognitive illusions—like optical illusions—hold us in their thrall, says Piattelli-Palmarini (Cognitive Science/Institute San Raffaele, Milan). But theoretical breakthroughs in cognitive science provide revolutionary new avenues for thought. Addressing everyone who wants to make more rational decisions, Piattelli- Palmarini unveils the ``discovery'' of the ``cognitive unconscious.'' This term, with its nod to Freud, refers to the reflexive patterns of reasoning in which we engage unreflectively, even though counterintuitive but logically correct thinking would serve us better. Asked, for instance, which outcome is more likely in a coin flip, ``heads-heads-heads'' or ``heads-tails-heads- tails,'' most people use incorrect logic to conclude that the latter is more likely (in fact, ``the longer the sequence, the less probable it is''). Piattelli-Palmarini explores the ``tunnels'' of cognitive illusion, showing how familiar problems, (drawn from the realms of medicine, demography, economics, and gambling) flummox most people. Then he corrects common misapprehensions, mapping the rational terrain that lies outside these tunnels, even making an arcane but crucial fact about statistics clear to the general reader. By revealing how most respondents err in, for instance, guessing someone's profession based on a personality profile, Piattelli-Palmarini rigorously defines the rules of probability and deduction. Some will object that what he calls ``irrationality'' is itself a function of the abstraction of such problems, but he vigorously defends cognitive science against such arguments. Perhaps less defensible is his pretense that its ideas represent a revolutionary breakthrough; the issues he raises are, after all, part of a 2,000-year-old philosophical debate. Whether or not his grand claims are justified, as a primer for problem-solvers, this book has great merit.

Greene (The 33 Strategies of War, 2007, etc.) believes that genius can be learned if we pay attention and reject social conformity.
The author suggests that our emergence as a species with stereoscopic, frontal vision and sophisticated hand-eye coordination gave us an advantage over earlier humans and primates because it allowed us to contemplate a situation and ponder alternatives for action. This, along with the advantages conferred by mirror neurons, which allow us to intuit what others may be thinking, contributed to our ability to learn, pass on inventions to future generations and improve our problem-solving ability. Throughout most of human history, we were hunter-gatherers, and our brains are engineered accordingly. The author has a jaundiced view of our modern technological society, which, he writes, encourages quick, rash judgments. We fail to spend the time needed to develop thorough mastery of a subject. Greene writes that every human is “born unique,” with specific potential that we can develop if we listen to our inner voice. He offers many interesting but tendentious examples to illustrate his theory, including Einstein, Darwin, Mozart and Temple Grandin. In the case of Darwin, Greene ignores the formative intellectual influences that shaped his thought, including the discovery of geological evolution with which he was familiar before his famous voyage. The author uses Grandin's struggle to overcome autistic social handicaps as a model for the necessity for everyone to create a deceptive social mask.
Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should beware of the author's quirky, sometimes misleading brush-stroke characterizations.Pub Date: Nov. 13, 2012

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.
The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.
