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.

If the authors are serious, this is a silly, distasteful book. If they are not, it’s a brilliant satire.


The authors have created a sort of anti-Book of Virtues in this encyclopedic compendium of the ways and means of power.

Everyone wants power and everyone is in a constant duplicitous game to gain more power at the expense of others, according to Greene, a screenwriter and former editor at Esquire (Elffers, a book packager, designed the volume, with its attractive marginalia). We live today as courtiers once did in royal courts: we must appear civil while attempting to crush all those around us. This power game can be played well or poorly, and in these 48 laws culled from the history and wisdom of the world’s greatest power players are the rules that must be followed to win. These laws boil down to being as ruthless, selfish, manipulative, and deceitful as possible. Each law, however, gets its own chapter: “Conceal Your Intentions,” “Always Say Less Than Necessary,” “Pose as a Friend, Work as a Spy,” and so on. Each chapter is conveniently broken down into sections on what happened to those who transgressed or observed the particular law, the key elements in this law, and ways to defensively reverse this law when it’s used against you. Quotations in the margins amplify the lesson being taught. While compelling in the way an auto accident might be, the book is simply nonsense. Rules often contradict each other. We are told, for instance, to “be conspicuous at all cost,” then told to “behave like others.” More seriously, Greene never really defines “power,” and he merely asserts, rather than offers evidence for, the Hobbesian world of all against all in which he insists we live. The world may be like this at times, but often it isn’t. To ask why this is so would be a far more useful project.

If the authors are serious, this is a silly, distasteful book. If they are not, it’s a brilliant satire.

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.

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our minds.
