Stupidity is far more dangerous than evil, for evil takes a break from time to time, stupidity does not.

Never argue with stupid people, they will drag you down to their level and then beat you with experience.

You can foresee a bandit’s actions, his nasty maneuvres and ugly aspirations and often can build up your defenses.With a stupid person all this is absolutely impossible as explained by Law # 3. A stupid creature will harass you for no reason, for no advantage, without any plan or scheme and at the most improbable times and places. You have no rational way of telling if and when and how and why the stupid creature attacks. When confronted with a stupid individual you are completely at his mercy.

A Double Attack - The Unforeseeable And The Patternless

The probability that a certain person be stupid is independent of any other characteristic of that person.Cipolla posits stupidity is a variable that remains constant across all populations. Every category one can imagine—gender, race, nationality, education level, income—possesses a fixed percentage of stupid people. There are stupid college professors. There are stupid people at Davos and at the UN General Assembly. There are stupid people in every nation on earth. How numerous are the stupid amongst us? It’s impossible to say.

Stupidity Law #2

The non-stupid are a flawed and inconsistent bunch. Sometimes we act intelligently, sometimes we are selfish bandits, sometimes we act helplessly and are taken advantage of by others, and sometimes we’re a bit of both. The stupid, in comparison, are paragons of consistency, acting at all times with unyielding idiocy.

Consistency Always Wins - The Revenge Of The Stupid

However, consistent stupidity is the only consistent thing about the stupid. This is what makes stupid people so dangerous. Cipolla explains:Essentially stupid people are dangerous and damaging because reasonable people find it difficult to imagine and understand unreasonable behavior.An intelligent person may understand the logic of a bandit, for example. The bandit’s actions follow a pattern of rationality: nasty rationality, if you like, but still rationality.

Consistent Stupidity Is All The Stupid Have, But It’s Plenty

Law 5: A stupid person is the most dangerous type of person.And its corollary:A stupid person is more dangerous than a bandit.We can do nothing about the stupid. The difference between societies that collapse under the weight of their stupid citizens and those who transcend them are the makeup of the non-stupid. Those progressing in spite of their stupid possess a high proportion of people acting intelligently, those who counterbalance the stupid’s losses by bringing about gains for themselves and their fellows.

Stupidity Law #5

Always and inevitably everyone underestimates the number of stupid individuals in circulation. No matter how many idiots you suspect yourself surrounded by, Cipolla wrote, you are invariably lowballing the total. This problem is compounded by biased assumptions that certain people are intelligent based on superficial factors like their job, education level, or other traits we believe to be exclusive of stupidity. They aren’t. Which takes us to:

Stupidity Law #1

They are abundant, they are irrational, and they cause problems for others without apparent benefit to themselves, thereby lowering society’s total well-being. There are no defenses against stupidity, argued the Italian-born professor, who died in 2000. The only way a society can avoid being crushed by the burden of its idiots is if the non-stupid work even harder to offset the losses of their stupid brethren.

Stupid People Share Several Identifying Traits

Non-stupid people always underestimate the damaging power of stupid individuals. In particular non-stupid people constantly forget that at all times and places and under any circumstances to deal and/or associate with stupid people always turns out to be a costly mistake.We underestimate the stupid, and we do so at our own peril. This brings us to the fifth and final law:

Stupidity Law #4

Think of how stupid the average person is, and realize half of them are stupider than that.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

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.Cipolla called this one the Golden Law of stupidity. A stupid person, according to the economist, is one who causes problems for others without any clear benefit to himself.

Stupidity Law #3

We are all born ignorant, but one must work hard to remain stupid.

Cipolla imagined the four types along a graph, like this:https://en.m.wikipedia.org/wiki/Carlo_M._Cipolla#/media/File%3ACipolla-matrix.svg

The 4 Phenotypes Graph

The difference between stupidity and genius is that genius has its limits.

Talk sense to a fool and he calls you foolish.

Declining societies have the same percentage of stupid people as successful ones. But they also have high percentages of helpless people and, Cipolla writes, “an alarming proliferation of the bandits with overtones of stupidity.”“Such change in the composition of the non-stupid population inevitably strengthens the destructive power of the [stupid] fraction and makes decline a certainty,” Cipolla concludes. “And the country goes to Hell.”

Decline And The Composition Of The Non-Stupid 

This law also introduces three other phenotypes that Cipolla says co-exist alongside stupidity.First there is the intelligent person, whose actions benefit both himself and others.Then there is the bandit, who benefits himself at others’ expense. And lastly there is the helpless person, whose actions enrich others at his own expense.

The 4 Phenotypes - The 3 Non-Stupid

Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.

In 1976, Carlo M. Cipolla, professor of economic history at the University of California, Berkeley published an essay outlining the fundamental laws of a force he perceived as humanity’s greatest existential threat: Stupidity. We (still) grossly underestimate the stupid, and we do so at our own peril.
