HARE BRAIN, TORTOISE MIND

HOW INTELLIGENCE INCREASES WHEN YOU THINK LESS

An argument for the seductive proposal that our unconscious intelligence is more productive than we think. Claxton, a visiting professor of psychology and education at Bristol University in England, builds his thesis on the dichotomy between the privileged mode of intelligence—conscious, result-oriented problem-solving—and the less respectable unconscious intelligence. This unconscious, or “undermind,” approaches problems playfully, examines the questions themselves, and keeps us in touch with our poetic nature. Claxton is admittedly using the tools of the enemy to prove his point’since we give weight to scientific thought, he will use scientific thought to show the merit of intuitive thought. His multidisciplinary approach is beautifully executed, with a constant dialogue on the virtues of intuition and a peaceful mind drawing on the works of poets, novelists, and Buddhist teachings. However, the slim thesis stretches thinly into 13 chapters as Claxton approaches his proposition from all sides—intuition, consciousness, biopsychology, reflections on society’s standards of intelligence. There’s plenty of meaty new research—parallels with instinct in animal behavior are especially intriguing—but the overall effect becomes repetitious, and chapters begin to seem padded and disjointed as the book progresses. And despite his pointed attention to fashionable currents in psychology (evolution, the rudiments of brain research), Claxton’s book feels dated and fussy. His metaphors are whimsical, and his repudiation of the speed of the modern age echoes neo-Luddite fears of a computerized world. There is only minor mention of gendered modes of thought, that his “undermind” corresponds with the nonlinear, intuitive process increasingly associated with women’s thinking. The pleasures of the “tortoise mind” tend to be poetic, very easy to romanticize. Claxton makes a last-minute case for how this mode of thought can be incorporated into the modern workplace, but his heart obviously lies in its abstract beauty. (12 b&w illustrations)

MASTERY

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should...

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.

THINKING, FAST AND SLOW

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

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.
