When we do something stupid, we like to blame others. But the older I get, the more I realize that I’ve done the most damage to myself—by myself.
Forget about acting on emotions. Forget about relying on intellect. The truth is, I’ve made stupid decisions—plain and simple. And those decisions often come back to haunt me. Why did I do this? Why did I do that?
There’s a point at which you have to let it go. We’re human. We’re not perfect.
But I’ve just been reading Fake Heroes, which references a short book called The Basic Laws of Human Stupidity by Italian economic historian Carlo M. Cipolla, first published in 1976. And let me tell you—once you see stupidity through Cipolla’s lens, you’ll start spotting it everywhere.
What is a Stupid Person?
Now, this is where it gets tricky. Stupidity isn’t always about lack of education or intellect. Often, what we call stupidity is driven by ego, vanity, greed, or even good intentions gone horribly wrong.
Take Thomas Midgley, for instance. Once hailed as a scientific hero, he introduced lead into petrol and invented CFC gases for refrigerators. Lead poisoning and ozone depletion followed. Today, many consider him one of the most damaging individuals to have ever lived. Was he stupid? Or was he just tragically wrong?
Cipolla gives us a useful definition.
A stupid person is someone who causes losses to others while gaining nothing themselves—and often incurring personal losses in the process.
So, unlike a “bandit” who harms others for personal gain, the stupid person just… creates wreckage. With no benefit to anyone, not even themselves.
The Five Laws of Human Stupidity (Cipolla’s Version)
Cipolla’s essay is both tongue-in-cheek and razor sharp. Here’s a potted summary:
1. We always underestimate the number of stupid people among us.
2. Stupidity is independent of other traits like education, class, or profession.
3. A stupid person harms others without benefiting themselves.
4. Non-stupid people underestimate how dangerous stupid people are.
5. Stupid people are more dangerous than bandits. You can anticipate a bandit. You can’t predict a fool.
This might sound harsh—but it explains a lot. Big decisions, national policies, corporate missteps, social media firestorms… stupid behavior is often at the core, dressed up as “bold vision” or “authenticity.”
Stupidity is Everywhere
Customers can act stupidly. So can businesspeople, politicians, friends, family members—even you and I.
Today, though, stupidity is often dressed up as influence. A guru. A thought leader. A disruptor. The packaging has changed, but the core remains.
That’s why I believe it’s crucial—especially now—to evaluate people’s ideas, claims, and stories with care. Just because someone shouts the loudest doesn’t mean they know what they’re talking about. Often, it’s quite the opposite.
There’s more to say about this, and I’ll revisit human stupidity in future posts. But for now, I leave you with this:
We all have moments of stupidity. The real danger begins when we stop recognizing them—or when we start celebrating them as genius.
