THE HIDDEN BRAIN

HOW OUR UNCONSCIOUS MINDS ELECT PRESIDENTS, CONTROL MARKETS, WAGE WARS, AND SAVE OUR LIVES

A tour into dark realms of the psyche by a personable guide.

A disturbing but enlightening look at the power of the unconscious over human action and decision-making.

Why did virtually everyone on the 88th floor of the South Tower of the World Trade Center survive on 9/11, while almost all of those on the 89th floor perished? Washington Post behavior columnist Vedantam (The Ghosts of Kashmir, 2006) uses that question to demonstrate how even the strongest willed can be subject to their unconscious minds. Sometimes this agency is for the good; often, however, our unconscious biases lead us into error. Shunning Freudian interpretation for more recent, evidence-based science, Vedantam cites studies in the United States, Canada and Europe that demonstrate how people are easily misled into acting on biases they would be shocked to learn they had. An honor box in a British office’s coffee room fills faster when a printed request for contributions is accompanied by a pair of watchful eyes. More harmful, people tend to rate the intelligence or competence of a total stranger downward when they are merely proximate to—not necessarily interacting with—an overweight person. Transsexuals who become men improve their lot while those who become women suffer economically and socially, all other aspects of their personalities remaining equal. School children of all races persist in applying positive attributes to white strangers and negative ones to people of color. These studies, Vedantam says, point out the tendency of humans to be ruled by the oceanic portion of our mind that keep us functioning in a complex world, while the conscious mind attends to only what it needs to—shockingly little in comparison.

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.

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.
