Off late, studying game-theory.Thought of scribbing some notes.
It a is powerful tool because it teaches long-term planning in the times when most of us focus on short-term gains and dopamine surges.
Life is not a sprint.One temporary victory is forgotten within a year; that’s the harsh truth. Learning this theory well can help you to condition your mind to play long -term games.
If someone has to sum-up game-theory in few words, we can say that game theory literally tells you all the things you need to succeed:
1. Reputation. Be the one people want to cooperate with. Fruitless betrayal destroys credibility.
2. Long-term planning. Not everything is a one-off game. Life is iterated. Building relations and networks in the first round yields benefits in the subsequent games.
3. Incentive alignment. Sharing goals and ambitions that can coexist avoids betrayal. But never purely look for shared goals; look for similar ambitions that synergize well.
4. Thinking Recursively. Determine where you want to be in 10 years (the end state). Then, work backward to the present to see which current path actually leads there. Never blindly think forward.
5. Plan around information. Success comes from either reducing asymmetry (being transparent to build trust) or leveraging it to your advantage.
But by far the most important lesson? Becoming a strategist.
NOW LET’S GO DEEP!
What is Game Theory?
Game theory is the mathematical study of strategic decision-making.
It is not about playing games like chess or poker rather it is a framework for analyzing situations where multiple people or groups are making choices, and the outcome for each participant depends heavily on the choices made by the others.
Think of it as the science of strategy.
Core Concepts:
1. The Core Components
Every scenario analyzed in game theory (referred to as a “game”) has a few basic elements:
Players: The decision-makers involved. These could be individuals, companies, government etc.
Strategies: The possible actions or choices available to each player.
Payoffs: The result every player receives based on the combination of strategies chosen by everyone.
This could be money, status, survival, or winning a market share.
2. The Classic Example: The Prisoner’s Dilemma
To understand how game theory works, look at its most famous thought experiment: The Prisoner’s Dilemma.
Imagine two criminals, Abdul and Wahid, are arrested.
The police do not have enough evidence to convict them of the crime, so they put them in separate interrogation rooms and offer them both a same deal:
If you betray your partner (testify against them) and they stay silent, you go free, and your partner gets 10 years in prison.
If you both stay silent, the police can only charge you with a minor offense, and you both get 1 year in prison.
If you both betray each other, you both get 5 years in prison.
The Dilemma (The Game Theory part):
Abdul sits in his room and thinks strategically.
1. What if Wahid stays silent? If Abdul stays silent, he gets 1 year. If he betrays him, he goes free. (Betraying is better).
2. What if Wahid betrays him? If Abdul stays silent, he gets 10 years. If he betrays him, he gets 5 years. (Betraying is still better).
Because betraying is the “best” individual choice regardless of what the other person does, both Abdul and Wahid will likely betray each other and get 5 years.
The tragic irony of the Prisoner’s Dilemma is that if they had just cooperated (stayed silent), they would have gotten the much lightersentencei.e. one year .
Game theory highlights how rational individual decisions can lead to worse outcomes for the group.
3. Key Concepts in Game Theory
Zero-Sum Game:A situation where one person’s gain is exactly equal to another person’s loss. If I win $10, you lose $10. Poker is a zero-sum game.
Non-Zero-Sum Game: A situation where all players can potentially win, or all can lose. Trade between countries is generally a positive non-zero-sum game (both benefit). War is a negative non-zero-sum game (both lose resources and lives).
Nash Equilibrium: Named after the mathematician John Nash (from the movie A Beautiful Mind).
This is a stable state in a game where no player has anything to gain by changing their own strategy while the other players keep theirs unchanged.
In the Prisoner’s Dilemma, both betraying each other is the Nash Equilibrium.
Stag Hunt Concept !
Hunting a stag ( a large animal ) vs. a rabbit !
The Stag Hunt shows one of the saddest truths about life.
People will often choose the smaller, safer reward they can secure fast and with low-risk rather than risk pursuing a much larger reward that requires patience, and conviction , real skin-in-the game .
Which is why so many lives are spent protecting certainty instead of building something bigger!
4. Where is Game Theory Used?
Some uses in daily life :
1. Game theory explains why first impressions are structurally almost impossible to reverse.
A positive initial assessment causes subsequent information to be substantially interpreted in its favor (halo effect).
A negative initial assessment does the exact opposite. This is ‘Bayesian updating’ with a strong ‘prior.’
The ‘prior’ established in the first 60 seconds becomes the lens through which every future action will be filtered.
You never get a second chance at a first impression because it, in itself, determines how the second impression is read in the first place.
That’s why the most trusted person in a room is the most dangerous individual in any environment.
Once they establish themselves as trustworthy, their actions cease being scrutinized through logic and rational thought.
While this potentially augments their output, it also grants them a vicious degree of autonomy. And if this person is not treated well, they are capable of eradicating the whole system.
Be careful who you trust. Ensure they deserve it, and treat them accordingly. They hold more power over you than you’d be willing to admit.
2.Game theory explains how trust is not a feeling but a probability.
In every interaction, your brain is running a continuous ‘Bayesian model.’
Every single new piece of evidence updates your predictions. This explains that trust is not built through pure warmth or shared history, but through variance reduction.
The most trusted person in the room is merely the one whose behavior has the lowest prediction error. Because when your behavior stays consistent, the people around you will assume they’ve figured you out.
And that manufactures trust. They will stop checking in on everything you do. They will start taking your word. And they will grant you more autonomy.
Game theory shows that trust is the universal currency.
Trust creates cooperation, a dominant strategy in most iterated games.
It can also deter the defectors. The man who is trusted by many is feared by the defector because his words can ruin the betrayer’s reputation: the cost of defection rises accordingly.
3 Loyalty is nothing but dependence in most of the cases.
Most loyalty is conditional.
In most of the scenarios ,loyalty is an alignment that can expire.
It holds because the cost of defection far exceeds the benefits of cooperation.
But as the structures change, so does loyalty.
They defect and betray. And when you have no grasp over the conditions of their loyalty, their defection is incentivized.
Loyalty is a commitment problem.
Game theory proves that the most dangerous allies are those whose loyalty depends on a condition you cannot influence.
In game theory, the easiest way to avoid being betrayed is to increase the price of defection.
It sounds simple because it is, yet most people fail to apply it.
For example, you don’t just break a law out of boredom because you know the punishment can be severe. The uncomfortable reason most people are betrayed repeatedly is that they don’t punish it properly.
“Forgive and forget” is a recipe for betrayal.
Game theory explains why people test you after you forgive them.
Forgiveness changes the model, but only consequences change the incentives.
If nothing actually shifts after betrayal, the other person has no reason to believe the boundary was real. They will not listen to your speech. They will run another experiment on your tolerance.
Game theory tells that you must be predictable when it comes to consequences.
In most cases, other players must know exactly what consequences they’ll face to properly dissuade them from defection.
It’s exactly what makes a good law: a clear directive and a clear punishment.
If you leave no room for interpretation and the consequences are clear and expensive, an opponent won’t try to provoke intentionally.
Other method is retaliation.
Retaliation is equally as important as cooperation.
Start by cooperating, but never let anyone cross you without retaliating.
This sets expectations. It shows others that you are willing to cooperate, but you are also not afraid to defend your interests.
It’s an invitation and a deterrent, purposefully balanced. Cooperate when possible, retaliate when needed.
Inaction or silence are other key components in a deal-making or a negotiation.
Silence can be the most powerful argument.
Whenever you respond immediately, you reveal data.
Your emotions, your priorities, and your level of threat can be inferred from this alone. Your opponent will adjust.
And that’s always to your detriment.
But when you remain silent, they gain nothing. They begin making up assumptions, usually unfavorable to themselves.
Even inaction, such as silence, can be a dominant strategy.
4. People act on incentives
If you asses through Game theory rules, yo realize that people do not act on information. They act on incentives.
You can give a person all the data they need to make a better decision, but as soon as that decision threatens their position or costs them something visible, they will try to ignore the data.
Before you ever try to convince anyone of anything, map what it costs them to agree. The cost of agreeing is the obstacle, not the argument.
5.Working harder may not be the solution in every situation
Game theory explains why working harder inside a broken system is the worst response to that system.
Because a system is never truly broken.
It’s just producing exactly the outcomes its own incentive structures were designed to produce, whether intentional or not.
Working harder inside this system increases your output in the payoff matrix, but it simply won’t change the actual structure of the system’s matrix.
Thus, the correct response is not more effort.
Instead, you must aim to identify whose interests the current structure serves and position yourself in favor of those interests rather than against them.
Change the game, or play the game that is actually being played. Either way, you must stop optimizing for the game you wish it to be and start acting realistically.
The most brutal part of game theory is that it does not care about your intentions, your loyalty, your pain, or your moral self-image; it only asks what the players can do, what each move pays, and whether your goodness is being punished by the structure of the game.
6. Understang motives is more important
As per Game theory, understanding someone’s motives is far more useful than understanding their argument.
Arguments can be constructed, but true motives can never be fully concealed.
Every position a person takes and every alliance they form secretly unveils a central incentive that they might not even be aware of.
To understand them, strip the argument entirely.
Instead, ask: “What does this person gain if they are believed?” The answer to this question predicts their next move far more accurately than any of their words.
Listen to their permanent actions, not their malleable words.
7.Cost of Winning
The most powerful strategy in any conflict is to make winning cost the other side more than losing. When the cost of defeating you exceeds the value of defeating you, rational opponents stop.
And history shows this all the time: The small guerrilla force miraculously defeats the empire.
Not necessarily because they are more powerful, but rather because every engagement with them is costly.
You do not need to be stronger to win. But you need to make the fight expensive.
8. Indifference
Indifference is either your greatest asset or your biggest downfall. On the one hand, it can reduce your cost to walk away to zero, giving you more bargaining leverage.
On the contrary,it can lead to bad decision-making due to a lack of urgency.
There’s a difference between strategy and apathy.
Game theory shows that indifference is leverage.
When one player cares far less about the outcome, they hold disproportionately higher power.
When your cost to walk away is effectively zero, your opponent is forced to cut their losses entirely or pressured into frantically negotiating to avoid total loss.
Burning bridges is other form of similar strategy.
It can be a viable strategy as indifference..
When you intentionally remove your own options, your threats become credible.
The opponent knows you cannot back down, so they must now calculate differently.
This is what a game theorist calls a commitment device.
This strategy is massively high-risk, but it can change the entire game by forcing your opponent to readjust.
9. Building Exits
Game theory explains why the person with fewer options becomes easier to control.
Desperation narrows the decision tree until every bad offer starts looking like survival.
This is why your first duty is to build exits.
Money, competence, reputation, allies, and emotional detachment are not luxuries. They are escape routes from being priced cheaply.
Caution :
Game theory teaches that even the best strategy can falter when it’s used in the wrong environment. No prebuilt strategy fits all environments.
What you truly need to build is a framework.
Strategies are static, but frameworks can offer contingencies and account for more threats.
Dynamic systems are the path to success, whether in business, politics, entrepreneurship, or general life.
Game theory is used across several fields,it is a foundational tool across many disciplines:
Economics: Understanding how competing companies set prices or bid in auctions.
Politics and International Relations: Analyzing nuclear deterrence during the Cold War or predicting how countries will negotiate treaties.
Evolutionary Biology: Understanding why animals adopt certain mating strategies or why altruism exists in nature.
Computer Science:Designing algorithms and routing network traffic.
If one wanna go deep ,there are many books on this topic e.g Games and Decisions
And here is something that is not directly related to game theory but it can give you some context ” Unonventional Leadership”.
