The Art of Strategy: A Game Theorist's Guide to Success in Business and Life (Summary)

by Avinash K. Dixit and Barry J. Nalebuff

In 1519, upon landing in Mexico, Hernán Cortés ordered his men to burn their own ships. It was a shocking, seemingly irrational act of self-sabotage. But Cortés understood game theory. By destroying his only means of retreat, he sent an unbreakable, credible signal to his men and his enemies: surrender was not an option. They would either conquer or die. This is the art of strategy—changing the game by manipulating your own choices.

To Win, Work Backwards from the End

The fundamental rule of strategic thinking is to start at the end. Instead of asking 'What should I do now?', a game theorist asks 'What outcome do I want?' and then traces the sequence of actions back to the present to determine the best initial move.

In chess, a grandmaster doesn't just react to their opponent's last move. They envision a future checkmate and work backward, anticipating all possible replies, to identify the optimal move to make right now. The entire game is a chain of logic starting from the desired conclusion.

Make Your Threats and Promises Believable

A threat, promise, or commitment is strategically useless unless your opponent believes you'll actually follow through. To make it credible, you must structure the situation so that it will be in your own best interest to carry it out when the time comes, often by limiting your own future options.

The 'doomsday machine' from the film Dr. Strangelove is a perfect example. It's an automated system that guarantees massive, world-ending nuclear retaliation if the country is attacked. By removing human hesitation, the threat becomes 100% credible, making it a powerful (and terrifying) deterrent.

Sometimes Cooperating is the Smartest Selfish Move

In many scenarios, like the famous Prisoner's Dilemma, if everyone acts in their own narrow self-interest, they all end up worse off than if they had cooperated. The key is to change the game from a one-shot interaction to a repeated game where reputation and future rewards encourage trust and collaboration.

During World War I, soldiers in the trenches often adopted an informal 'live-and-let-live' system. A unit would intentionally fire to miss the enemy, and the enemy would return the favor. This unspoken cooperation, born from the knowledge that they would face each other again tomorrow, saved countless lives—a far better outcome for both sides than all-out aggression.

Use Information as a Strategic Weapon

Strategic situations are often defined by what you know and what your opponent doesn't. You can gain an edge by 'signaling' (credibly revealing hidden information) or by 'screening' (designing choices that force your opponent to reveal their own hidden information).

A university degree is more than just an education; it's a signal to employers. A company can't easily tell who is a hard worker. But by requiring a degree, they screen for people who have demonstrated the discipline and ability to complete a difficult, multi-year project, regardless of the specific subject matter studied.
