A Gladwellian exploration of the brain’s inner workings during the decision-making process.
Given the recent deluge of pop-science books, readers may find it difficult to make a selection. Enter Seed and Scientific American contributor Lehrer’s second book (Proust Was a Neuroscientist, 2007), a laudable attempt to help people understand how their brains make decisions—and hopefully, improve the process. On the former point, the book is a treasure trove of scientific data, clinical research and real-life examples of decision-making processes. On the latter point, however, it leaves something to be desired. At its best, Lehrer’s narrative is a compelling mixture of recently discovered facts and intriguing theories about the differences between the rational and emotional centers of the brain. The author’s research indicates, somewhat counterintuitively, that the emotional areas are the primary drivers when making complex decisions that involve multiple variables, such as purchasing a house or car. Lehrer also looks at anecdotal evidence of those theories in action, ranging from the incredible efforts of a pilot to land a plane after its hydraulic systems failed (a prime example of using the reason center of the brain to conquer fear and take action) to clinical experiments involving tests to see how long unsupervised four-year-olds can resist a marshmallow (not very, in most cases). In its most effective chapters, the book ties research to practical applications, such as a 401(k) program designed to overcome our irrational need for immediate reward (to the detriment of long-term saving) by deferring the start of the program until a few months after employment begins. Other sections lack the same practical applicability, and the vague generality of much of the decision-making advice feels more therapist than scientist.

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.

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
