Critical Thinking Is Dead. Here’s the Truth About Human Stupidity.

You know the exact feeling. You’re sitting in a meeting, reading a thread online, or watching the news, and someone makes a decision so catastrophically irrational that it harms everyone involved—including them. You try to apply logic. You point out the obvious flaws. And nothing changes. You walk away exhausted, wondering if you’re the one losing your mind.

You aren’t. You’ve just collided with the most dangerous force in human history.

Back in 1976, an Italian economic historian named Carlo Cipolla published a brilliant, cynical essay outlining the fundamental laws of human stupidity. He didn’t define stupidity as a low IQ. He defined it as an independent, unmeasurable force. According to Cipolla, a stupid person is someone who causes harm to another person, or a group of people, while gaining absolutely no benefit from the action. In fact, they often harm themselves in the process.

Stupidity isn’t a lack of intelligence; it’s a black hole of rational self-interest that drags everyone else into the dark.

We’ve been taught a comforting lie: that education, critical thinking, and better access to information will eventually inoculate society against irrationality. If we just teach people how to think, the logic goes, they’ll stop acting against their own interests. But this completely misunderstands the nature of the threat.

Stupidity, by definition, is immune to reason. Because the actor isn’t pursuing a rational goal, no rational incentive structure can deter them. If someone cuts off their nose to spite their face, you can’t negotiate with them by offering a better face-cutting deal. They just want to cut.

You cannot negotiate with a force that gains nothing by destroying you.

For most of human history, this was a localized problem. The village idiot could cause a lot of local chaos, but the blast radius was limited. They couldn’t easily coordinate with other village idiots in neighboring towns to amplify their damage. The irrationality was isolated, and society could mostly route around it.

Then we built the internet.

The real shift isn’t that individuals have gotten stupider. It’s that digital platforms have taken isolated foolishness and turned it into a coordinated collective phenomenon. Algorithms don’t reward truth; they reward engagement. And nothing drives engagement quite like outrage and irrationality. We connected all the village idiots, gave them a global megaphone, and handed them the keys to systemic infrastructure.

The internet didn’t make us smarter; it just gave the village idiot a global megaphone.

This makes Cipolla’s 1976 warning more urgent than ever. Stupidity has scaled from a personal nuisance to a systemic threat. When irrational actors network, their collective decisions can crash markets, derail democracies, and destroy institutions—all without any of them gaining a single tangible benefit.

So what do you do? You stop trying to save them. Critical thinking won’t protect you from being collateral damage in someone else’s irrational crusade. The only winning move is to recognize the pattern. Identify the irrational actors in your workplace, your social circles, and your public life. Understand that they will act against their own interest, which means they will absolutely act against yours. Don’t debate them. Don’t try to out-argue them. Just step out of the blast radius, and let the gravity of their own black hole consume them.
