Is the title a little bit extreme? Yes, it is. But it's also true. Extremists are always wrong. But we'll have to figure out why the statement itself is not wrong.

Extremism is wrong

An extreme is a maximum or minimum of something. It's the most extreme case of something. An extremist is someone who takes something to the extreme.

At first, this might sound extreme or even like a paradox. A paradox is a statement that seems to go against common sense, or that appears to contradict itself. In this case, the statement “Extremists are always wrong” uses an absolute term—always—which makes it sound like the person saying it is also being an extremist!

But let's break it down and see why there's actually no contradiction once we define what "extremist" means.

Defining “Extremist”

An extremist is someone who holds a belief about how the real world works—and refuses to change that belief no matter what evidence or measurements come along. They won't even consider new information. In other words, an extremist says, "I'm right, and nothing you show me—photos, scientific data, or logical arguments—can make me change my mind."

Example 1: Someone who insists the Earth is flat, despite satellite photos and airplane routes showing otherwise.
Example 2: Someone who believes a certain medicine never works, even though multiple scientific studies prove it does.

The Difference Between Definitions and Measurements

Why does this matter? Because there's a big difference between definitions (like in math) and measurements (in science or real-world observations).

Definitions (Formal Systems)
- Example: "1 + 1 = 2."
- This is true inside the system we've defined (standard arithmetic). We agreed on how we add numbers, so "1 + 1 = 2" isn't really based on measuring the world—it's based on rules we invented and accepted.
Measurements (Empirical Reality)
- Example: "The Earth is roughly spherical," or "Air has weight."
- We can test these statements and gather evidence. If someone refuses to believe the Earth is round, despite photos from space and other data, they're going against real-world proof.

So, Why Are Extremists "Always Wrong"?

When people will not change their beliefs no matter what the evidence shows, they set themselves up for being proven wrong eventually—because in the real world, we can measure and observe. If your belief doesn't match these observations, then over time, the proof will stack up against you.

Earth is round: The evidence is overwhelming (pictures, experiments, geometry). If you refuse it all, you're likely holding a wrong belief.
Medicine works: If many scientific studies show it helps, ignoring this evidence is also likely to be incorrect.

Thus, the statement "Extremists are always wrong" specifically targets people who hold absolute beliefs about the real world without caring about the facts or measurements. Eventually, they'll clash with reality and be shown wrong.

But Isn't That Statement Itself an Extreme?

Yes, saying "always wrong" sounds absolute. That's where the paradox feeling comes in. A paradox is something that makes you think, "Hey, isn't that contradictory?"

Key Point: The statement isn't about math rules (like 1 + 1 = 2) or personal preferences (like ice cream flavors). It's about factual claims that can be tested in the real world.
By "extremist," we mean people who ignore all evidence against their view. If measurements keep proving a view incorrect, but someone refuses to change their mind, they're bound to stay wrong.

In other words, we're talking about empirical (measure-based) beliefs. If a person says, "I will never change my belief no matter how many measurements you show me," they're basically doomed to end up wrong—because the truth relies on facts, not on stubbornness.

When we say "Extremists are always wrong," it might sound paradoxical at first—maybe even contradictory. But once we define extremists as people who ignore all evidence that shows they might be wrong, we see there's no real contradiction. If you're talking about the real, measurable world, shutting yourself off from reality guarantees you'll end up on the wrong side of the facts sooner or later.

Definitions are about agreed-upon rules (like in math).
Measurements are about what we can see, test, and observe in real life.
Extremism is refusing to consider evidence in the face of real-world measurements. And that's what makes it "always wrong."
