The Antisocial Contract (Simple Version) • Append Only

The Big Idea

People naturally sort themselves into groups. Once you’re in a group, your brain starts doing something sneaky: it makes you like your group more and trust other groups less. This happens automatically, even when the groups are made up for no real reason.

This isn’t always bad. Liking your team can make you work harder together. But sometimes this “us vs. them” thinking gets so strong that it makes smart people do dumb things — and it’s really hard to stop once it starts.

How It Works

Step 1: Making Teams

If you split people into teams — even by something silly like flipping a coin — they immediately start favoring their own team. Scientists tested this. People gave more points to their own team members even when they’d never met them and the teams meant nothing.

Your brain is built to do this. It’s not something you choose.

Step 2: Some Teams Feel More Important

Some groups feel more important than others. Your family feels more important than “people who like the same ice cream flavor.” Religious groups, countries, and political parties often feel really important because they’re connected to big questions like “who am I?” and “what matters?”

When a group feels important, it gets harder to leave. It becomes part of who you are.

Step 3: The Team Becomes Part of You

Sometimes people get so attached to their group that they can’t tell the difference between “someone insulted my group” and “someone insulted me.” It feels the same.

When this happens, any criticism of the group feels like a personal attack. Your brain switches from “let me think about this” to “I need to defend myself.”

Step 4: Ideas Become Untouchable

Here’s where it gets weird.

Once something becomes really important to your group’s identity, your brain stops treating it like a normal idea. It becomes sacred — not in a religious way necessarily, but in a “you can’t question this” way.

Scientists did an experiment: they offered people money to change their minds about things they cared deeply about. Instead of thinking “hmm, how much money would make this worth it?” — which is how we normally think — people got angrier. Offering money made them more stubborn, not less.

It’s like their brains said: “This isn’t for sale, and how dare you ask.”

Step 5: Smart Doesn’t Help

Here’s the really surprising part: being smart doesn’t protect you from this.

In fact, smarter people are sometimes better at defending beliefs they already have. Their brain uses all its horsepower to find clever reasons why they’re right — not to figure out if they’re actually right.

It’s like having a powerful car engine but the steering wheel is stuck. You go faster in the wrong direction.

Step 6: You Can’t Back Down

Once a whole group believes something is sacred, nobody can back down — even the leaders.

Imagine a game where everyone in your class agreed that the blue team is bad. Even if you (the team captain) realize the blue team isn’t actually bad, you can’t say so. Your own teammates would get mad at you and pick a new captain who hates the blue team more.

This happens with politicians all the time. They sometimes know they should compromise, but they can’t — because their supporters would replace them with someone who won’t.

The Trap

Here’s the really tricky part. This “us vs. them” thinking actually works for groups trying to compete with each other.

Groups that are really tight and really suspicious of outsiders tend to:

Stick together better
Work harder for the group
Have more kids who stay in the group
Beat groups that are more relaxed and open

So groups that think this way win against groups that don’t.

But Here’s the Problem

What helps a group beat other groups destroys the bigger community that all the groups live in.

Think about it like this:

Imagine a park where everyone can play. If one team starts hogging the swings and pushing other kids away, that team gets more swing time. They “win.”

But if every team starts doing this, nobody can use the park anymore. Fights break out. The park gets ruined.

What’s good for one team is bad for everybody.

A scientist named E.O. Wilson said it like this: “Selfish people beat generous people. But groups of generous people beat groups of selfish people.”

The version for our problem: “Open-minded groups lose to closed-minded groups. But communities full of open-minded groups do better than communities full of closed-minded groups.”

The Referee Problem

Sometimes there are rules or bigger organizations that stop groups from fighting too much. Countries have laws. Schools have teachers. The world has international agreements.

These are like referees. They keep the game fair so everyone can play.

But here’s the catch: the groups that would win if there were no referee really want to get rid of the referee.

If you’re the team that likes pushing other kids off the swings, the teacher is your enemy. You want the teacher to go away.

This is why some politicians attack international organizations, courts, or even elections. These things stop them from winning, so they want to break them.

Teams that would win without rules have every reason to destroy the rules.

Real Examples

When Countries Fall Apart

Yugoslavia was a country made of different groups (Serbs, Croats, Bosniaks). For a long time, a strong government kept them from fighting. When that government fell apart, leaders started telling each group that the other groups were dangerous enemies.

Within a few years, neighbors who had lived together peacefully were killing each other. Over 100,000 people died.

The groups weren’t ancient enemies. Leaders made them into enemies because it helped those leaders get power.

When Smart People Believe Silly Things

During the Cold War, America and the Soviet Union both thought they were the good guys and the other side was evil. Scientists on both sides used their big brains to explain why their side was right — not to figure out what was actually true.

American scientists helped build nuclear weapons while Soviet scientists defended fake biology theories that their leader liked. Both groups were smart. Both groups used their smarts to defend their team, not to find truth.

When Slogans Beat Policies

In America, most people (76%) supported the idea of moving police money to better training and mental health help. But when the same idea was called “Defund the Police,” only 21% supported it.

Same idea. Different team signal. Totally different reaction.

Once “Defund the Police” became a team slogan, people who invented it couldn’t take it back — even when they saw it was hurting their own goals. The words had become sacred to some supporters.

Why This Matters

This isn’t about one group being bad. The same trick happens everywhere:

Religious groups
Political parties
Countries
Even sports fans

The pattern is:

Make a team
Team becomes important to who you are
Team ideas become untouchable
Smart thinking gets used to defend, not question
Leaders get trapped by their followers
Everybody loses (except the team that happened to be on top when everything broke)

Can We Fix It?

The honest answer: it’s hard.

Some ideas that might help:

Notice when it’s happening. Just knowing about this trick makes you a little more resistant to it. Ask yourself: “Am I thinking about this, or just defending my team?”
Have friends in other groups. It’s harder to see another group as evil when your friend is in it.
Change the rules. Some countries use voting systems that make it harder for just two teams to form. When there are many teams, you have to work together instead of just beating the other side.
Protect the referees. Courts, elections, free press, international agreements — these are the things that stop groups from destroying each other. When someone attacks them, ask: “Would this person win if the referee was gone?”
Make it safe to change your mind. In a lot of groups, changing your mind looks like betrayal. But being able to say “I was wrong” is actually a sign of strength, not weakness.

The Bottom Line

Your brain is built to join teams and fight for them. This helped your ancestors survive.

But now we live in a world where we need to cooperate with millions of people we’ll never meet. The old team-fighting instinct causes more problems than it solves.

The groups that are best at the team-fighting game tend to win. But when everyone plays that game, the whole world loses.

Understanding this is the first step toward not being tricked by it.
