Rock, Paper, Scissors: Game Theory in Everyday Life [Paperback]

Len Fisher (Author)

Book Description

Publication Date: November 4, 2008

Praised by Entertainment Weekly as “the man who put the fizz into physics,” Dr. Len Fisher turns his attention to the science of cooperation in his lively and thought-provoking book. Fisher shows how the modern science of game theory has helped biologists to understand the evolution of cooperation in nature, and investigates how we might apply those lessons to our own society. In a series of experiments that take him from the polite confines of an English dinner party to crowded supermarkets, congested Indian roads, and the wilds of outback Australia, not to mention baseball strategies and the intricacies of quantum mechanics, Fisher sheds light on the problem of global cooperation. The outcomes are sometimes hilarious, sometimes alarming, but always revealing. A witty romp through a serious science, Rock, Paper, Scissors will both teach and delight anyone interested in what it what it takes to get people to work together.

From Publishers Weekly

Physicist and Ig Nobel Prize–winner Fisher (How to Dunk a Doughnut) explores how game theory illuminates social behavior in this lively study. Developed in the 1940s, game theory is concerned with the decisions people make when confronted with competitive situations, especially when they have limited information about the other players' choices. Every competitive situation has a point called a Nash Equilibrium, in which parties cannot change their course of action without sabotaging themselves, and Fisher demonstrates that situations can be arranged so that the Nash Equilibrium is the best possible outcome for everyone. To this end, he examines how social norms and our sense of fair play can produce cooperative solutions rather than competitive ones. Fisher comes up short of solving the problem of human competitiveness, but perhaps that is too tall an order. Game theory works better as a toolkit for understanding behavior than as a rule book for directing it. Fisher does succeed in making the complex nature of game theory accessible and relevant, showing how mathematics applies to the dilemmas we face on a daily basis. (Nov.)

From Booklist

Fisher, author of the entertaining and educational How to Dunk a Doughnut (2003), explores how the seemingly amorphous notion of cooperation can be explored, quantified, and even modified through the new science of game theory, which isn’t about games in the usual sense of the word. Rather, game theory concerns the strategies we use when we interact with other people. It’s about the way we manipulate situations to our own advantage; the way we negotiate and weigh our options before making decisions; the way we instinctively make split-second decisions based on myriad potential outcomes. Through a combination of real-world examples (like a traffic jam that took three days to unclog) and philosophical problems, Fisher shows us that we’re way more cooperative than we sometimes think we are, while at the same time startlingly more selfish than we ought to be. As with Doughnut, the writing is lively, the scientific discourse clear and accessible, and the ideas challenging and exciting. --David Pitt

More About the Author

Australian-born (1942), my main achievements after a life in science have been the award of an IgNobel Prize for using physics to work out the best way to dunk a biscuit, the creation of a carrot clarinet for the Oxford Symposium on Food and Cookery, and the invention of a champagne jelly that keeps its fizz (the more serious stuff about me and my activities is on my webite at lenfisherscience.com). My books are intended to reveal what really goes on in science, and to share the science that I love, by showing how scientists think about the important and not-so-important problems of life. I now divide my time between England's West Country and the Blue Mountains near Sydney, Australia, following the theory that an endless summer provides the best conditions for writing. The picture was taken in the mountains of Ecuador, the jumping off point for a lifelong ambition to visit the Galapagos Islands.

5.0 out of 5 stars Best introduction to game theory, May 26, 2009

A good example of how to write at the "popular" end of the popular science spectrum. Game theory in general deals with settings in which each player has to choose one of several strategies without knowing other players' choices, and gets a payoff depending on everyone's choices (note this is rather different from what we call games in everyday language). Such games typically have a Nash equilibrium, which (roughly speaking) is the result when players behave selfishly; but there may be some different "cooperative" choices of strategies that would make everyone better off (a "social optimum"). This paradox or "logical trap" is usually illustrated by the Prisoner's Dilemma story. Observing where this situation occurs and contemplating ways of getting around them by "self-enforcing strategies" -- how cooperation might be achieved in the face of temptations to cheat -- are the main themes of the book, which is well paced and engagingly easy to read. Some highlights are

(1) Discussion of "7 deadly dilemmas" given cute names by theorists (Prisoner's Dilemma; Tragedy of the Commons; Free Rider; Chicken; Volunteer's Dilemma; Battle of the Sexes; Stag Hunt) -- models in which there is math theory.

(2) A lengthy verbal discussion of strategies to promote trust and cooperation (e.g. making it costly to change your mind later; deliberately cutting off your escape routes).

(3) Martin Nowak's 5 rules for the social evolution of cooperation.

While the in-text accounts of scientific studies in the human social world or in biology are conversationally casual, the end-notes (comprising 1/5 of the book) provide citations to the scientific literature -- a definite improvement on most books at this level.

All popularizers tend to exaggerate the scope of applicability of their subject, but this book less so than most. Let me just mention two ways in which the real world is more complicated than the book implies.

(4) Except in special cases where the payoff is money and nothing else matters, the payoff has to be modeled as some number of abstract "points" (or "utils", in jargon) which one can't actually measure. And then any observed behavior can be construed as optimal behavior in some game theoretic model. So game theory is more like a useful way of thinking about issues, and less like a traditional scientific theory which makes testable predictions

(5) In complicated real world economic situations, trying to make everyone better off is both fiendishly complicated and involves some kind of tax and subsidy scheme; introducing such things creates its own moral hazard outside the context of the one particular game.

5.0 out of 5 stars Very readable - game theory for everyday, December 22, 2008

Having just picked up this book as a game theory practitioner, I found this to be an excellent read. My work which centers primarily around the work of Thomas Schelling has led me to a variety of books on the game theory topic. Even Dr. Schelling, who has a comfortable writing style, evokes examples beyond the "everyday" realm, applicable to political and global challenges, more frequently than the cocktail parties and family life.

I found this book ties together the work of many of the top thinkers in the field, including recent Nobel Prize winners, taking a breadth rather than depth approach and at the same time provides the accessibility and application to experiences in everyday life. The few diagrams, and limited "math" will lower the barrier that other fine writers have created in their coverage of the topic. This is not to say it is "dumbed down". Quite the contrary, it is put in an everyday perspective and therefore worthy of consumption by a wider audience.

For further information, and for delving more formally into the topic, an extensive bibliography is provided, itself about 20% of the book. For the person interested in looking beyond this books level, there are many references to research.

All in all I think it fills a specific gap existing in connecting this important topic to our everyday lives. This topic, which explains so much about our relationships, how we do cooperate, and frequently don't , is worth a good read.

This review is from: Rock, Paper, Scissors: Game Theory in Everyday Life (Paperback)

This book is a very, very elementary introduction to game theory. If you know anything about game theory at all, expect to get very bored, very fast reading this book. As another reviewer wrote, it is heavy on fluff, and light on actual theory/math/science, so if you are looking for a book that will make you think, this is not it.
