When some people hear the term “The Art of War,” they instinctively think of ancient battlefields and military strategy—something far removed from modern life. But if we look at it from another angle, military strategy is often not really about “warfare” itself. Rather, it is about how people assess situations, information, risks, and choices, and how they respond accordingly.
And when placed into today’s world of work, relationships, cooperation, competition, and even life decisions, this way of thinking feels surprisingly relevant.
From the perspective of Game Theory, this mindset is not distant at all, because Game Theory itself studies the following question:
When your decisions influence others, and others’ decisions in turn influence you, how will the situation evolve?
I remember taking a Game Theory course back in school.
When the professor talked about John Nash, he emphasized one particular idea:
Great research is often not about “how long it is written,” but about “what truly important idea it introduces.”
Nash later shared the 1994 Nobel Prize in Economic Sciences with John C. Harsanyi and Reinhard Selten for their pioneering analysis of equilibria in non-cooperative game theory. Interestingly, Nash’s famous 1950 paper, Equilibrium Points in n-Person Games, was only two pages long. He later expanded the framework more systematically in his 1951 paper, Non-Cooperative Games.
At the time, this left a deep impression on me.
Because it reminded me that:
truly valuable ideas do not necessarily need lengthy explanations to prove their worth.
Sometimes, a single clear and precise concept—one that changes how people think—is enough to influence an entire era.
And Game Theory is exactly that kind of discipline.
It helped me realize that many problems we assume are merely “personal choices” actually contain deeper layers of situation analysis and interactive structures. In many ways, this is also what military strategy has always tried to discuss.
1. Don’t Think of Military Strategy as Something Distant: It Is Really About “Reading the Situation”
Put simply, The Art of War is still widely discussed today not merely because it is an ancient text, but because it addresses a fundamental human ability: understanding the conditions of a complex situation before deciding how to act.
Britannica describes The Art of War as one of the earliest known works on military strategy and military science, as well as a systematic guide to strategy and tactics. It particularly emphasizes understanding factors such as enemy and ally conditions, information, terrain, leadership, and deployment.
If we replace the word “battlefield,” we begin to realize that this resembles many of the decisions we make every day:
- Should I change jobs? 💼
- Should I take the initiative to propose collaboration first? 🤝
- Should I stand firm or take a step back? ⚖️
- Is this opportunity a short-term gain or a long-term cost? ⏳
The true appeal of military strategy is not that it feels “powerful” or “mysterious,” but that it reminds us of something important:
before making decisions, we should not only look at the options in front of us, but also consider the broader situation, costs, information, and the possible reactions of others.
This way of thinking is actually very close to how modern people navigate important life decisions.
2. What Is Game Theory? And Why Does It Help Us Understand Life?
Game Theory is not about gambling, nor is it about teaching people how to manipulate others.
In the simplest terms, it analyzes the following:
when participants’ decisions are interdependent, how will they choose, and what outcomes will ultimately emerge?
Britannica defines Game Theory as a framework for analyzing situations of interdependent decision-making, where each participant must take into account the possible strategies of others when making choices.
Although this concept sounds academic, it is actually deeply connected to everyday life.
Because in reality, most important decisions are never determined by only one person:
- You want to cooperate, but is the other side willing to do so?
- You want to compromise, but will the other side push further and take advantage?
- You want to uphold your principles, but will the market, team, or environment allow it?
In other words, what we often face is not simply “which answer is best,” but rather:
when everyone else is also observing, judging, and making choices, what should I do?
This perspective of making decisions within interaction is precisely what makes Game Theory so fascinating. And interestingly, it also helps us reinterpret military strategy from a modern perspective.
Because military strategy has never been merely about force—it is fundamentally about making choices within a situation.
3. What I Remembered from the Classroom Was Not Just Nash, but a Way of Thinking 📘
One of John Nash’s most famous contributions was the concept later known as the Nash Equilibrium.
Britannica explains it this way: in a non-cooperative situation, if the strategies of all other participants remain unchanged, and no individual can improve their outcome by changing only their own strategy, then the situation is considered a Nash equilibrium.
At first, this idea may sound somewhat abstract, but it is actually very close to reality.
Because it reveals something deeply important:
Very often, the situation people end up staying in is not the most ideal one — but it may be the most stable.
For example, two companies may both understand that constantly engaging in price wars is harmful. Yet as long as neither side can be certain the other will stop first, both may continue lowering prices. The final outcome may not be optimal, but it becomes stable.
This is precisely what makes the Nash equilibrium so fascinating: it does not describe “the perfect world,” but rather the position where people become stuck under mutual constraints.
And interestingly, this way of thinking is very similar to military strategy.
Military strategy is not merely about telling you “what should ideally be done.” More importantly, it asks:
under existing conditions, where will the situation push people toward — and how can you recognize that invisible force?
4. What Military Strategy and Game Theory Have in Common: They Both Ask “How Do You Read the Situation, Instead of Only Looking at Moves?” 🔍
Over time, I increasingly felt that military strategy and Game Theory belong in the same conversation not simply because they both discuss “strategy,” but because they both force us to do the same thing:
step away from isolated thinking and examine the entire structure of interaction.
4.1 Look at the Situation, Not Just Your Wishes
The Art of War begins by treating warfare as a matter of survival and destruction, emphasizing that multiple conditions must be evaluated before making decisions. In Lionel Giles’ English translation archived by Project Gutenberg, Sunzi highlights several key factors: Tao, Heaven, Earth, Command, and Method — referring to values and morale, timing, environment, leadership, and systems.
If we translate these ideas into modern language, the message is surprisingly practical:
before making decisions, first examine whether values are aligned, whether the timing is mature, whether the environment is supportive, whether leadership is stable, and whether the system can keep up.
4.2 Value Information, Not Just Intuition
Britannica also points out that The Art of War strongly emphasizes understanding the enemy’s information, positioning, movement, and overall situation, treating accurate information as a critical foundation for strategic judgment.
When applied to life, this idea feels anything but ancient.
Whether you are considering quitting your job, entering a partnership, starting a business, or investing in a relationship, the question is often not simply “Does this feel right?” Instead, you should first ask yourself:
Do I actually have enough information? Or am I only seeing the surface?
4.3 The Real Calculation Is Not Just Whether You Can Win, but Whether It Is Worth It
World History Encyclopedia also notes that The Art of War repeatedly reminds readers that warfare is a high-cost form of exhaustion that should be avoided whenever possible. Truly brilliant strategy is not about fighting every battle, but about avoiding situations that trap you in expensive and prolonged direct confrontation.
This insight is highly relevant to life itself. Many decisions are not merely about “Can I do it?” but rather:
Is this truly worth the amount of time, emotion, resources, and risk I must invest?
This is, in many ways, the essence of mature decision-making: not merely focusing on victory or defeat, but evaluating whether the cost is proportional to the outcome.
5. The Prisoner’s Dilemma: Why Do People Fail to Cooperate Even When Cooperation Is Better? 🔒
One of the most famous scenarios in Game Theory is the Prisoner’s Dilemma.
Let me explain it through a concrete example.
A common version described by Britannica goes like this: two suspects are interrogated separately and cannot communicate with each other. If only one confesses, the confessor is immediately released while the other may receive a 20-year sentence. If neither confesses, both receive only a few months in prison. But if both confess, each receives a 15-year sentence.
The Prisoner’s Dilemma
| Prisoner A / Prisoner B | Prisoner B Does Not Confess | Prisoner B Confesses |
|---|---|---|
| Prisoner A Does Not Confess | Both receive a few months in prison | A receives 20 years, B is immediately released |
| Prisoner A Confesses | A is immediately released, B receives 20 years | A receives 15 years, B receives 15 years |
The most interesting part of this example is that:
if we only look at the overall outcome for both sides, then “neither confesses” is clearly the better result because both receive only a few months in prison.
However, from the perspective of individual self-interest, confessing appears to be the safer choice.
Because from Prisoner A’s perspective:
- If B does not confess and I confess, I get released immediately.
- If B confesses, then I should also confess, because at least I receive 15 years instead of carrying the full 20 years alone.
So from A’s perspective, regardless of what B chooses, “confessing” seems like the safer option. And B will likely think the same way.
As a result, the most likely outcome becomes:
both prisoners confess, and both end up serving 15 years.
This is exactly what makes the Prisoner’s Dilemma so classic:
each individual makes what appears to be the most rational choice for themselves, yet together they arrive at an outcome that is worse for everyone involved.
The Prisoner’s Dilemma is not famous because it talks about prisons. It is famous because it exposes one of the most common tensions within human society:
From the perspective of the individual, betrayal often feels safer.
But from the perspective of the collective, cooperation is clearly better.
This is the core tension of the Prisoner’s Dilemma:
Individual rationality does not always lead to the best collective outcome.
And this situation is remarkably close to everyday life.
5.1 In the Workplace
Everyone on a team may understand that sharing information and supporting each other would produce better overall results. Yet people may still worry:
If I contribute more first, will others simply contribute less?
As a result, everyone holds back, and the entire team becomes less effective.
5.2 In the Market
Two companies may both realize that endless price-cutting harms both sides. But if I keep prices stable while you lower yours, I may suffer first. So both companies reduce prices, and both struggle together in the end.
5.3 In Human Relationships
Very often, people are not unwilling to be honest — they are afraid that being honest first will put them at a disadvantage. They are not unwilling to trust — they fear being betrayed after trusting.
This is exactly why the Prisoner’s Dilemma resonates so deeply:
It is not that I do not want to cooperate — I am simply afraid that I will be the only one who does.
And this is also where military strategy and Game Theory suddenly feel very close to modern life: both remind us that
many problems are not simply about good or bad choices, but about insufficient trust and flawed structures of interaction.
6. So Is Cooperation Difficult? Actually, the Key Is Whether People Will Meet Again 🤝
The good news is that Game Theory does not simply tell us that “human nature is selfish.”
On the contrary, many studies suggest that when interactions are not one-time events but continue over time, cooperation becomes far more likely to emerge.
In Britannica’s extended discussion of the Prisoner’s Dilemma, it is mentioned that when the same interaction repeats continuously, strategies such as Tit for Tat — cooperating first and then responding based on the other side’s previous action — can gradually stabilize cooperation.
This actually aligns very closely with real-life experience.
Once both sides understand that “this is not the only time we will interact,” many decisions begin to change:
- You begin to care more about reputation.
- You become more aware of how today’s actions may influence tomorrow.
- You also start to realize that cooperation is not naïve optimism, but a conditional and structured possibility.
So the truly important question is not simply “Will people cooperate?” but rather:
- Will the interaction continue?
- Does betrayal carry a cost?
- Will goodwill be recognized and reciprocated?
- Is there room for repair after mistakes?
I personally love this perspective because it moves us away from simplistic moral judgments about whether people are “good” or “bad,” and toward a more mature understanding:
if we want good outcomes to emerge, we often cannot rely solely on everyone being naturally kind. Instead, we must create structures in which cooperation becomes worthwhile.
7. If We Bring Military Strategy Back Into Life, What Does It Truly Teach Us? 🪞
If we stop reading military strategy merely as manipulation, and stop viewing Game Theory as cold mathematical calculation, but instead treat them as ways of understanding the world, then I believe they remind us of at least several important things.
7.1 First Ask Yourself: Am I Seeing the Surface, or the Situation?
When people are anxious, it is easy to focus only on immediate choices:
Should I change jobs? Should I end the relationship? Should I commit? Should I refuse?
But both military strategy and Game Theory remind us that what truly matters is not merely “which option to choose,” but rather:
where is this situation heading, and what conditions are shaping the outcome?
7.2 Do Not Only Ask “What Do I Want?” — Also Ask “How Will Others Respond?”
One of the core ideas of Game Theory is that your decisions never happen in a vacuum.
If you move forward, others may retreat.
If you compromise, others may push further.
If you choose honesty, the other person may accept it — or remain silent.
This is not telling us to become suspicious of everyone. Rather, it reminds us that:
mature decision-making cannot consider only our own desires; it must also consider the consequences of interaction.
7.3 The Best Strategy Is Not Always the Most Aggressive — It Is the Most Appropriate for the Moment
Britannica’s introduction to Sun Tzu points out that The Art of War emphasizes flexibility, accurate information, and adapting to changing conditions, rather than rigidly relying on a single method.
This is equally important in life.
Because many times, persistence is not automatically more mature, and compromise is not automatically weakness. What truly matters is:
within this timing, this relationship, and this environment, what choice is most appropriate?
7.4 Many Problems Are Not About Winning or Losing — They Are About Cost
The Art of War repeatedly reminds readers of the enormous costs of conflict. World History Encyclopedia also notes that the text does not glorify conflict itself, but instead emphasizes avoiding high-cost direct confrontation whenever possible.
When applied to modern life, this becomes a deeply important reminder:
Sometimes you win the argument, but lose the relationship.
Sometimes you seize the opportunity, but the price is too high.
Sometimes a position appears admirable, yet causes you to lose greater long-term possibilities.
Therefore, truly mature thinking is not merely asking:
“Can I win?”
But rather:
“Is the price I pay truly worth the result I gain?”
8. 🌱 You Have Probably Been Thinking in Game Theory All Along
Many people feel that Game Theory sounds highly mathematical or technical, as though it only belongs to people studying economics, computer science, or statistics.
But the more I think about it, the more I feel that Game Theory is simply a more systematic way of describing what we already do every day:
- Predicting how others may respond
- Deciding whether we should act first
- Weighing short-term and long-term consequences
- Considering the right timing for cooperation, competition, compromise, or waiting
In other words, you do not need to write equations to understand Game Theory.
If you have ever made choices in life, then you have already been living inside Game Theory.
And the reason military strategy still feels meaningful today is precisely because it does not only discuss ancient warfare. It speaks about situations we still face now:
Incomplete information, changing circumstances, other people making choices, and every step carrying a cost.
When viewed this way, military strategy suddenly no longer feels distant at all.
It is simply using the language of the ancient world to express a problem modern people still face today:
when situations are complex and answers are never absolute, how do we make better judgments?
9. Conclusion: Military Strategy Is Not Far from Life — It Is Very Close to Decision-Making ✨
If I had to summarize this entire article in one sentence, I would say this:
The true value of military strategy is not that it teaches us how to confront others, but that it teaches us how to make judgments within complex situations;
and Game Theory provides a modern language that helps us reinterpret this idea.
Nash’s story taught me that truly powerful ideas are not necessarily long, but they are always deep.
The Art of War taught me that good decision-making is not merely about visible victory or defeat, but about first understanding conditions, information, timing, cost, and the reactions of others.
So military strategy is actually not far from life at all.
It exists not only on battlefields, but also within every moment when we ask ourselves:
- Should I speak up or remain silent?
- Should I take responsibility or step back?
- Should I cooperate or stay cautious?
- Is this the moment to change direction?
And Game Theory reminds us that these decisions are difficult not because we are unintelligent, but because we always live within a world where our choices continuously influence — and are influenced by — others.
Perhaps understanding this alone already brings us one step closer to making wiser and more mature decisions.
