The phrase “good faith” gets thrown around a lot in online arguments, usually as an accusation. “You’re not arguing in good faith” has become shorthand for “you’re arguing in a way I don’t like.” But what does good faith debate actually look like?

It’s not about being polite, though politeness helps. It’s not about finding middle ground, though compromise sometimes emerges. Good faith debate is about genuinely trying to understand someone else’s position and present your own in ways they can understand. It’s harder than it sounds.

The Steel Man Principle

Bad faith debaters attack straw men—weak or distorted versions of their opponent’s argument. Good faith debaters do the opposite: they engage with the strongest version of the opposing view.

This means doing your opponent’s work for them sometimes. If they’ve made a point poorly, you restate it more clearly. If they’ve missed an obvious supporting argument, you acknowledge it. You’re not trying to win on technicalities or gotchas.

Why would you do this? Because if you defeat a weak argument, you haven’t learned anything or changed anyone’s mind. If you can defeat the strongest version of an argument, you’ve actually accomplished something.

I see this rarely online and occasionally in person. Most debate involves finding the weakest point in someone’s position and hammering it repeatedly. That might feel satisfying, but it’s intellectually lazy.

Acknowledging Trade-offs

Almost every policy question involves trade-offs. Good faith debate acknowledges this. Bad faith debate pretends your preferred option has only benefits while the alternative has only costs.

Take immigration. Open borders advocates might emphasise economic benefits and humanitarian obligations. Restrictionists might emphasise social cohesion and wage protection. Both are highlighting real considerations. Both are ignoring inconvenient facts.

Good faith debate means acknowledging the legitimate concerns on the other side. Yes, immigration creates economic growth, and yes, rapid demographic change creates social friction. Yes, we have humanitarian obligations, and yes, communities need time to adapt. These aren’t contradictions—they’re the actual complexity of the issue.

When someone refuses to acknowledge any downside to their position or any benefit to the alternative, they’re not debating in good faith. They’re selling.

Allowing for Uncertainty

We don’t know everything. Good faith debate allows space for uncertainty. Bad faith debate demands certainty and attacks any expression of doubt as weakness.

“I’m not sure” should be an acceptable answer to some questions. “The evidence is mixed” should be a valid position. “I could be wrong about this” should be normal rather than remarkable.

But our media environment punishes uncertainty. Pundits who hedge get ignored. Politicians who express doubt get hammered for flip-flopping. Social media rewards confident pronouncements, even when confidence isn’t justified.

This creates an environment where everyone has strong opinions about everything, even topics they learned about five minutes ago. That’s not healthy debate—that’s performance.

Defining Terms

So many arguments are actually about definitions rather than substance, but nobody notices because we don’t stop to define terms.

Take “socialism.” Some people mean Soviet central planning. Others mean Scandinavian social democracy. Others mean worker ownership of industry. You can have a three-hour argument about socialism where everyone’s talking about completely different things.

Good faith debate establishes what words mean before arguing about them. “When I say X, I mean Y. What do you mean when you use that term?” This feels pedantic, but it’s necessary for productive disagreement.

Bad faith debaters deliberately use terms ambiguously, switching definitions mid-argument when it’s convenient. They’ll defend “socialism” by pointing to Denmark, then critique it by pointing to Venezuela, without acknowledging they’re discussing different systems.

Changing Your Mind Is Normal

I’ve changed my mind about important things multiple times. Not because I’m wishy-washy, but because I encountered better arguments or new evidence. This should be seen as intellectual growth, not character weakness.

Good faith debate allows for this. You can say “that’s a good point, I hadn’t considered it” without feeling like you’ve lost. You can acknowledge when someone has identified a flaw in your reasoning.

Bad faith debate treats any shift in position as admission of defeat. Once you’ve staked out a position, you defend it forever regardless of what you learn. This is politics poisoning discourse—in politics, changing your position is seen as weakness. In actual thinking, it’s just learning.

What About Civility?

Notice I haven’t said anything about being nice. That’s deliberate. Good faith debate doesn’t require politeness, though it’s often easier when people are civil.

You can aggressively challenge someone’s position while still engaging in good faith. You can be blunt about flaws in their reasoning. You can use strong language about bad ideas.

What you can’t do in good faith is misrepresent their position, ignore their strongest arguments, or refuse to engage with the actual substance of disagreement. Those are bad faith moves regardless of tone.

Conversely, you can be perfectly polite while arguing in bad faith. Corporate PR and political spin are often very civil while being completely dishonest. Civility matters for keeping discussions from devolving into name-calling, but it’s not the same as good faith.

The Audience Problem

Most public debate isn’t really aimed at convincing your interlocutor—it’s aimed at convincing the audience watching. This fundamentally changes the dynamic.

If you’re trying to convince the person you’re debating, you need to engage with their actual position and speak to their concerns. If you’re trying to impress an audience, you need to deliver zingers and make your opponent look foolish.

Good faith debate is almost impossible when there’s an audience to perform for. Everyone’s incentivised to score points rather than reach understanding. This is why Twitter is such a terrible place for nuanced discussion—every argument has hundreds or thousands of observers.

The best debates I’ve had were one-on-one, in private, where neither of us was performing for anyone else. We could acknowledge uncertainty, change positions, and explore ideas without worrying about how it looked.

Why Bother?

If good faith debate is this hard and this rare, why bother? Because it’s the only way to actually learn anything from disagreement.

Echo chambers feel comfortable but they’re intellectually stagnant. You need exposure to serious challenges to your views, presented by intelligent people who genuinely believe different things. That’s how you discover the holes in your own reasoning.

But those challenges only work if they’re made in good faith. If someone’s just scoring points or misrepresenting your position, you learn nothing except maybe to avoid talking to them.

The alternative to good faith debate isn’t winning arguments—it’s everyone talking past each other forever, getting angrier and more convinced of their own righteousness. We’re watching that happen in real time.

Good faith debate is difficult, often frustrating, and rarely produces clear winners. But it’s the only path to actual understanding. Everything else is just noise.
