This book is an engaging, comprehensive guide to strategies, as applied to everyday life. The first part of the book focuses on standard game theory, graphical notations for various problems, and applications of the prisoners' dilemma to everyday situations. The second part of the book concentrates more on everyday and business problems, and strategies to achieve optimal solutions. Game theory is not always applicable to all of these problems, but logic and rational problem-solving and a bit of mathematics are ever-present.
The book explores the voting issue in some detail. When two candidates are running against each other, the best strategy of course is to vote for your first choice. When three or more candidates are running, it is not always best to vote for your first choice, especially if you believe that your first choice has no chance of winning. For example, in the presidential election of 2000, there were three candidates, Bush, Gore, and Nader. If you preferred Nader to the others, you could vote for him, but your vote would be pretty much wasted, as he had little chance of winning. It would be best to vote for your second choice. But, what if the election was predicted to be much closer; what would the best strategy be then?
Furthermore, the book explores other voting systems that would allow you to list all of your voting preferences? For example, what if you could vote on all of the candidates, listing their names in preferential order. Various vote-tallying systems could take these preferences into account, and come up with a fairer assessment of the most-preferred candidate.
But here's the rub; there are numerous vote-tallying systems, each of them objective, but depending on which one is chosen, a different candidate could win. The book goes into some detail in considering the different outcomes of the 2002 presidential race, considering several of these systems.
The book also describes three different systems for auctions. Although the systems differ dramatically, the optimum strategy is the same for all of the systems.
The book describes various approaches for political negotiations. Examples include incentives and threats. But a threat is only good if it is credible. The book describes some historical approaches that have made threats credible. Another type of strategy is how a company can best compete with other companies, by setting prices that will maximize profitability.
The book has a set of exercises to try out your newly-gained understanding. One of the exercises is to consider how to make a good first impression on a first date. You are faced with two simultaneous problems; how to prove your sincerity and quality to your date, and how best to assess the sincerity and quality of your date. In other words, what is the best strategy for signaling and screening?
This book is best appreciated if you are not afraid of some simple algebra. However, many of the strategies are not at all mathematical, but simply rely on logic. I thoroughly enjoyed this book; some of the chapters were a bit repetitive, but not overly so.
