The cuckoo succeeds by exploiting the natural inclination that bigger is better. The female cuckoo sneaks into the nest of another species when the parent bird is away and displaces an egg with one of its own. The egg resembles those of the host but is usually a little larger and brighter. The nest owner consequently sits on the cuckoo’s egg in preference even to its own. The young cuckoo’s beak is a little wider and redder than any other that survive and its preferential treatment continues. This phenomenon was given the name Supernormal Stimuli by Nobel Prize Winner Nico Tinbergen, who discovered examples throughout nature. Geese would attempt to sit on volleyballs in preference to their eggs and Sticklebacks would attempt to mate with brightly painted sticks in preference to less brightly coloured females. These might sound like the rather sad behaviour of ‘simple’ creatures, but the book’s subtitle hints at how the same behaviours can be found in ourselves. Following a chapter that explores Nico Tinbergen’s life there are six chapters that each explores an aspect of the effects of supernormal stimuli in human affairs. Sex for Dummies Whilst we may mock the Stickleback, this chapter explores how we’ve developed entire industries dedicated to the reshaping of the human form for sexual stimulation. Too Cute Discover the power of cuteness and how our behaviours to other people and animals are triggered and conditioned by a simple set of criteria. Foraging in Food Courts Explores how our basic instincts developed for life on the savannah have been exploited to create the obesity epidemic and the reasons for our inability to respond effectively. Defending Home, Hearth and Hedge Fund 3000 people died in 9/11 and in 2001 41,370 Americans died in road traffic accidents. Discover why we react so differently to these two tragedies and what makes us ready to fight. Vicarious Social Settings from Shakespeare to Survivor Explores the impact of television and other media encourage us to live our lives vicariously through the lives of others and the impact this has in creating sedentary lifestyles. Intellectual Pursuits as Supernormal Stimulii Helps illuminate the interest we find in games and puzzles and how our career choices are influenced. It includes some salutary pointers to the future where for example the pursuit of what is interesting in the field of human cloning will override controls on its prevention. It seems to me that an inability to be content in having enough is at the heart of conflict between groups and unhappiness in individuals. Much of our Western way of living is built upon cultivating this sense of discontent. We must always be striving for something out of reach. This book helps explain how our basic instinct can be subverted, but also offers us help. Unlike the stickleback, we are able to stand back and observe and should we choose, to make changes. The final chapter ‘Get Off the Plaster Egg’, implores us to do so. no reviews | add a review
In this book, a Harvard evolutionary psychologist explains how our once-helpful instincts get hijacked in our garish modern world. Our instincts--for food, sex, or territorial protection--evolved for life on the savannahs 10,000 years ago, not in today's world of densely populated cities, technological innovations, and pollution. We now have access to a glut of larger-than-life objects, from candy to pornography to atomic weapons--that gratify these gut instincts with often-dangerous results. Animal biologists coined the term "supernormal stimuli" to describe imitations that appeal to primitive instincts and exert a stronger pull than real things, such as soccer balls that geese prefer over eggs. The author applies this concept to the alarming disconnect between human instinct and our created environment, demonstrating how supernormal stimuli are a major cause of today's most pressing problems, including obesity and war.

If you think about it, it's a concept that probably explains a lot about human beings and all the weird and often unhealthy things we're into. Well, Deirdre Barrett has thought about it a lot, and she does think it explains a lot... But unfortunately the book she's written about it wasn't really the one I wanted to read on the subject. There is some science here, some relevant statistics, and some useful perspectives. But, honestly, the whole thing often feels less like an exploration of an important scientific phenomenon and its relevance to human culture and psychology and more like an exercise in complaining about What's Wrong With the World Today and trying to shame people out of doing anything fun. Science mixes with opinion, nuances get lost, and entire swathes of human artistic endeavor get dismissed as a waste of time. Even the chapter on why we find exaggeratedly baby-featured things cute -- an absolutely classic example of supernormal stimuli at work -- ends with what feels very much like the author desperately trying to come up with a reason to disapprove of that, too. And the chapter on why war is bad -- not, I hasten to add, an assertion I disagree with -- feels only tenuously connected to the concept of supernormal stimuli at all.
All of which maybe makes it sound a lot worse than it is. I mean, there are certainly some good points in here, and it does at least serve to introduce an important topic that I suspect we should be paying a lot more attention to as we try to understand this artificial world we've created and how we interact with it. But it's still definitely not the book I wanted it to be. ( )
