In the late 1970s, political scientist Robert Axelrod organized a series of groundbreaking computer tournaments based on a famous game known as the Prisoner’s Dilemma. In this game, two players must decide independently whether to cooperate or betray each other. If both players cooperate, they receive a moderate reward (3 points); if one betrays while the other cooperates, the betrayer gets a high reward (5 points) and the cooperator gets nothing; if both betray, they both receive 1 point. The net result of this scoring system is simple: players acting rationally and in their own self-interest are incentivized to betray while players thinking about the greater good are incentivized to cooperate.
While simple in theory, the Prisoner’s Dilemma is a staple in the robust field of game theory and has been the basis for extensive debates and hundreds of research papers in various fields such as economics, political science, psychology, and sociology. The game also has considerable implications in business, touching everything from strategy formation and vendor negotiations to process engineering and conflict resolution. And so, it’s not surprising that Axelrod’s famous tournament uncovered some fascinating takeaways that we can leverage to improve the performance of our teams and our businesses.

The goal of Axelrod’s tournament was to explore the most effective strategies for the Prisoner’s Dilemma. Participants were invited to submit computer programs, each representing their own unique strategy for playing the game. These programs then competed against each other in a round-robin format, playing a series of games in which each match consisted of numerous rounds. The scoring system was based on the cumulative points earned across all rounds and matches. This setup allowed strategies to be evaluated not just on a single decision but on their ability to perform well over time in repeated interactions.
Programs ranged from rudimentary strategies such as always cooperating or always defecting to more complex, adaptive strategies that would change their behavior based on the opponent’s actions. Somewhat surprisingly, however, the most successful strategy turned out to be a straightforward program called “Tit for Tat,” which started with cooperation and then mirrored the opponent’s previous move in subsequent rounds.
Analyzing the success of Tit for Tat, Axelrod’s tournament highlights four key takeaways we can leverage to promote positive relationships in the workplace.
1. Be Nice
The success of Tit for Tat against its more aggressive counterparts demonstrates the power of simple cooperation. By starting our interactions with a collaborative approach, we set a tone of mutual trust and goodwill. This encourages those others to reciprocate, creating a foundation for mutually beneficial engagements.
2. Be Forgiving
Mistakes, missteps, and misunderstandings are inevitable in any professional relationship. Tit for Tat showed that forgiveness is an essential ingredient of cooperation. After responding to defection with defection, Tit for Tat would immediately return to cooperation as soon as its opponent did. This breaks cycles of retaliation and paves the way for long-term, win-win relationships.
3. Don’t Be a Pushover
Being nice and being forgiving may be essential components of any effective working relationship. But Tit for Tat’s success also shows the importance of having a backbone. The program’s strategy prevented exploitation by standing firm in the face of defection. Similarly, we must take reasonable steps to show those around us that unfair treatment will not be tolerated.
4. Be Clear
Finally, the success of Tit for Tat demonstrates the importance of clarity and consistency in our actions. The program was successful in large part because it was predictable and straightforward, making its behavior easy to understand. Similarly, this sort of transparency in our real-world actions allows others to better anticipate our needs and respond in kind. Being clear about our intentions and actions reduces misunderstandings and fosters a stable and cooperative environment.

Axelrod’s tournament provides powerful insights into the dynamics of cooperation. Among a large field of competitive programs, a simple strategy based on common-sense principles — be nice, be forgiving, have a backbone, and be clear — emerged as the most effective approach. Applied consistently in our businesses, these simple principles lay the groundwork for an environment of mutual trust and long-term collaboration.
