The Hidden Brain: How Our Unconscious Minds Elect Presidents, Control Markets, Wage Wars, and Save Our Lives

Most of us would agree that there’s a clear—and even obvious—connection between the things we believe and the way we behave. But what if our actions are driven not by our conscious values and beliefs but by hidden motivations we’re not even aware of?

 

The “hidden brain” is Shankar Vedantam’s shorthand for a host of brain functions, emotional responses, and cognitive processes that happen outside our conscious awareness but have a decisive effect on how we behave. The hidden brain has its finger on the scale when we make all our most complex and important decisions: It decides whom we fall in love with, whether we should convict someone of murder, and which way to run when someone yells “Fire!” It explains why we can become riveted by the story of a single puppy adrift on the ocean but are quickly bored by a story of genocide. The hidden brain can also be deliberately manipulated to convince people to vote against their own interests, or even become suicide terrorists. But the most disturbing thing is that it does all this without our knowing.

Shankar Vedantam, author of The Washington Post’s popular “Department of Human Behavior” column, takes us on a tour of this phenomenon and explores its consequences. Using original reporting that combines the latest scientific research with compulsively readable narratives that take readers from the American campaign trail to terrorist indoctrination camps, from the World Trade Center on 9/11 to, yes, a puppy adrift on the Pacific Ocean, Vedantam illuminates the dark recesses of our minds while making an original argument about how we can compensate for our blind spots—and what happens when we don’t.

The hidden brain is the voice in our ear when we make the most important decisions in our lives—but we’re never aware of it. The hidden brain decides whom we fall in love with and whom we hate. It tells us to vote for the white candidate and convict the dark-skinned defendant, to hire the thin woman but pay her less than the man doing the same job. It can direct us to safety when disaster strikes and move us to extraordinary acts of altruism. But it can also be manipulated to turn an ordinary person into a suicide terrorist or a group of bystanders into a mob.

In a series of compulsively readable narratives, Shankar Vedantam journeys through the latest discoveries in neuroscience, psychology, and behavioral science to uncover the darkest corner of our minds and its decisive impact on the choices we make as individuals and as a society. Filled with fascinating characters, dramatic storytelling, and cutting-edge science, this is an engrossing exploration of the secrets our brains keep from us—and how they are revealed. 

Shankar Vedantam is a national correspondent and columnist for the Washington Post and a 2009 Neimann Fellow.  He lives in Washington, DC.
