The Five Laws of Stupidity (And Why It Will Get You Killed If You Don't Protect Yourself)

Stupid people are everywhere. And sometimes they're in charge.

On my first night of apprentice classes, our instructor didn't show up.

He was in the resting up at home.

Want to know why?

He'd been working on a scissor lift in a parking structure. He positioned it perpendicular to the slant of the structure, raised it too high, shifted the center of gravity, and the whole thing tipped over.

And I remember sitting there thinking:

That was my first warning.

That I had to watch out for myself.

Because there are idiots everywhere. And sometimes they're in charge.

The Five Laws of Human Stupidity

In 1976, Italian economic historian Carlo Cipolla wrote a book called The Basic Laws of Human Stupidity.​

It should be required reading for anyone who has to work with other humans.

Here are Cipolla's five fundamental laws:

Law 1: Always and inevitably, everyone underestimates the number of stupid individuals in circulation.

You think you know how many stupid people are out there. You don't. There are more. Way more.

Law 2: The probability that a certain person will be stupid is independent of any other characteristic of that person.

Smart people can be stupid. Rich people can be stupid. Educated people can be stupid. Position, credentials, experience—none of it protects against stupidity.

Law 3: A stupid person is a person who causes losses to another person or to a group of persons while himself deriving no gain and even possibly incurring losses.

This is the key definition. Stupid people don't just harm themselves. They harm others. And they don't even benefit from it.

Law 4: Non-stupid people always underestimate the damaging power of stupid individuals.

You think you can manage them. You think you can work around them. You think you can protect yourself. You can't. Because you underestimate how much damage they can do.

Law 5: A stupid person is the most dangerous type of person.

More dangerous than a criminal. More dangerous than a malicious person. Because stupid people are unpredictable. They don't follow rational patterns. They cause harm without reason.

Corollary: A stupid person is much more dangerous than a pillager.

A pillager acts in self-interest. You can predict their behavior. You can defend against them. A stupid person acts irrationally. You can't predict them. You can't defend against them. You can only avoid them.

The Day an Apprentice Died Because His Journeyman Was an Idiot

One of the worst stories I heard in my career was about an apprentice who died moving a scissor lift.

His journeyman told him to move the lift from one room to another.

The kid driving from atop the lift, not wanting to damage the door frame, leaned over the guardrail to watch the wheels and body of the lift as he drove it through the doorway.

He was focused on not hitting the frame. So focused that he didn't realize the guardrail at the end of the lift was coming up behind him.

He kept driving. The guardrail pinned his head between itself and the door frame. The lift kept moving forward. He lost his grip on the controls.

His head didn't get ripped off.

He asphyxiated.

While his journeyman wasn't looking after him and didn't see what was happening.

Didn't watch him. Didn't warn him. Didn't stop him.

And that kid died because his journeyman was a fucking idiot.

It's Happened to All of Us (But We Learn)

Here's the thing that pisses me off the most about that story:

It's happened to all of us the first time we drive a lift through a door.

You focus on the wheels. You focus on not hitting the frame. And then you realize—too late—that your body or the guardrail is about to hit something.

Most of us learn. We adjust. We get more careful. We figure it out.

But idiots don't.

And other people get caught in the shrapnel.

Why Stupid People Are So Dangerous

Cipolla's fifth law is the most important one:

A stupid person is the most dangerous type of person.

Here's why:

1. Stupid People Don't Follow Rational Patterns

A criminal acts in self-interest. A malicious person acts with intent. You can predict their behavior. You can defend against them.

But a stupid person? They act irrationally. They make decisions that harm themselves and others for no reason. You can't predict them. You can't defend against them.

2. Stupid People Don't Learn from Mistakes

Most people make a mistake, feel the consequences, and adjust their behavior.

Stupid people make the same mistake over and over. They don't learn. They don't adapt. They don't improve.

3. Stupid People Cause Collateral Damage

When a stupid person makes a mistake, they don't just hurt themselves. They hurt everyone around them.

The journeyman who didn't watch his apprentice? He didn't die. The apprentice did.

The instructor who tipped over the scissor lift? He got hurt. But he could have killed someone below him.

Stupid people create shrapnel. And if you're standing too close, you get hit.

4. Stupid People Are Often in Charge

This is the most terrifying part.

Intelligence, competence, and good judgment are not prerequisites for leadership.

Stupid people get promoted. Stupid people get authority. Stupid people make decisions that affect other people's lives.

And if you're working under them, you're in danger.

We're seeing it every day on the news, around us, and often times with our family.

Trashcan Al and the Idiots in the Trades

In construction, we had stories.

Trashcan Al was infamous in LA, I know guys who worked with him. He got his name because his measurements for laying out some underground conduits to come up out of the concrete pour were the 50-gallon drums used as trashcans, not noticing them getting moved when emptied.

The guy who put his wiggy tester on a 4160-live circuit because he wanted to see what would happen. The tester blowing up in his hand and luckily the solenoid shooting out of the tester didn't kill anyone.

Guys who don't lock out the panel before working on it. Someone else turns the power back on. And they're pissed because they get bit or hooked up.

These weren't freak accidents. These were stupid decisions made by people who should have known better.

And in every case, they didn't just hurt themselves. They endangered everyone around them.

The Problem with Tolerating Stupidity

Here's what happens when you tolerate stupid people:

1. You Normalize Dangerous Behavior

When you don't call out stupidity, you signal that it's acceptable. Other people see it and think, "I guess that's how we do things here."

And then the stupidity spreads.

2. You Put Yourself at Risk

If you work with stupid people, you are in danger. Period.

They will make a decision that puts you at risk. They will create a situation you can't predict. They will cause harm you can't avoid.

3. You Enable Them

When you cover for stupid people, you enable them. You protect them from the consequences of their actions. And they keep being stupid.

4. You Lose Good People

Smart, competent people don't stick around in environments where stupidity is tolerated.

They leave. They find safer places to work. Places where leadership protects them from idiots.

And you're left with a concentration of stupid people. Which makes everything worse.

How to Protect Yourself from Stupid People

You can't eliminate stupid people. But you can protect yourself from them.

Here's how:

1. Recognize Them Early

Cipolla's first law: You underestimate how many stupid people are out there.

So assume there are more than you think. And learn to recognize them.

Warning signs:

• They don't follow basic safety protocols
• They make the same mistakes repeatedly
• They blame others for their mistakes
• They take shortcuts that endanger others
• They dismiss warnings and advice
• They don't think through consequences

If you see these signs, stay away from that person.

2. Set Boundaries

As a leader, you need to set healthy boundaries about what you will and will not do.

You will not work in unsafe conditions. You will not follow instructions that violate protocol. You will not put yourself at risk because someone else is too lazy or too stupid to do things right.

And you need to enforce those boundaries.

3. Speak Up

When you see stupidity, call it out.

Not to be a dick. Not to embarrass someone. To protect people.

If someone's about to do something dangerous, you stop them. You warn them. You explain why it's a problem.

And if they don't listen? You escalate. You go to their supervisor. You document it. You protect yourself and others.

4. Don't Cover for Them

When stupid people make mistakes, let them face the consequences.

Don't fix their work. Don't take the blame. Don't make excuses for them.

Because when you cover for them, you enable them. And they keep being stupid. And eventually, someone gets hurt.

5. Remove Yourself from the Situation

If you can't change the environment, leave.

If you're working under someone who's dangerously stupid, and management won't do anything about it, get out.

Your life is more valuable than any job.

6. Watch Out for Others

As a leader, you have a responsibility to protect people from stupidity.

That means:

• Training people properly
• Enforcing safety protocols
• Calling out dangerous behavior
• Not assigning inexperienced people to work with idiots
• Creating a culture where people can speak up without fear

Because if you don't watch out for others, they get caught in the shrapnel.

Why Leaders Must Protect People from Stupidity

That apprentice who died didn't deserve to die.

He made a mistake. A common, understandable mistake. The kind of mistake every apprentice makes.

But his journeyman didn't protect him. Didn't watch him. Didn't stop him.

And he died.

That's on the journeyman. That's on the leadership that allowed that journeyman to supervise someone. That's on the culture that tolerated stupidity.

And that's why leaders must protect people.

Not just from external threats. From internal ones.

From the idiots who cause harm without thinking. From the stupid people who endanger others for no reason.

The Cost of Stupidity

Stupidity isn't just annoying. It's costly.

It costs time. It costs money. It costs efficiency.

And sometimes, it costs lives.

When a stupid person makes a decision, people get hurt. Projects get delayed. Equipment gets damaged. Money gets wasted.

And the stupid person? They walk away unscathed. While everyone else picks up the pieces.

That's Cipolla's third law in action.

The One Thing You Need to Do Right Now

If you take one thing from this, let it be this:

You are responsible for protecting yourself from stupid people.

Not HR. Not your boss. Not the system. You.

Because stupid people are everywhere. They're more common than you think. They're more dangerous than you realize.

And if you don't set boundaries, speak up, and remove yourself from dangerous situations, you will get caught in the shrapnel.

So recognize them. Avoid them. Protect yourself and others.

Because the fifth law is real:

A stupid person is the most dangerous type of person.

And if you forget that, it might cost you everything.

Reply with this: One time you worked with someone dangerously stupid—and whether you protected yourself or got caught in the shrapnel.
