4. Description How our once-helpful instincts got hijacked by our garish modern world.Have you ever wondered why some men choose pornography over actual women? Why so many people watch Friends instead of going out with their own buddies? Why a person would 8220feed8221 a plastic Pocket Pet while shirking real duties? Why both sides of every war see the other as the aggressor against whom their 8220Department of Defense8221 must respond?Harvard evolutionary psychologist Deirdre Barrett explains how human instincts8212for food, sex, or territorial protection8212developed for life on the savannah ten thousand years ago, not for today8217s world of densely populated cities, technological innovations, and pollution. Evolution, quite simply, has been unable to keep pace with the rapid changes of modern life. We now have access to a glut of larger-than-life objects8212from candy to pornography to atomic bombs8212that gratify outmoded but persistent drives with dangerous results.In the 1930s Dutch Nobel laureate Niko Tinbergen found that birds that lay small, pale-blue eggs speckled with gray preferred to sit on giant, bright-blue, plaster dummies with black polka dots. He coined the term 8220supernormal stimuli8221 to describe these imitations that appeal to primitive instincts and, oddly, exert a stronger attraction than real things. Obviously these hard-wired preferences pose a danger to a species8217 survival. Barrett8217s singular insight is to apply this phenomenon for the first time to the alarming disconnect between human instinct and our created environment. Her book adroitly demonstrates how supernormal stimuli are a driving force in many of today8217s most pressing problems, including obesity, our addiction to television and video games, and the past century8217s extraordinarily violent wars. Man-made imitations, it turns out, have wreaked havoc on how we nurture our children, what food we put into our bodies, how we make love and war, and even how we understand ourselves.Barrett does more than pull the fire alarm to show how these unfettered instincts fuel dangerous excesses. There is a hopeful message here as well. Once we recognize how supernormal stimuli operate, we can craft new approaches to modern predicaments. Humans have one stupendous advantage over Tinbergen8217s birds: a giant brain. The message of this book is that this gives us the unique ability to exercise self-control, override instincts that lead us astray, and save ourselves from civilization8217s gaudy traps.
