Steelmanning is the practice of strengthening an opposing argument before engaging it. Instead of attacking the weakest version — the strawman — you build the strongest plausible version: the steelman. You state the other side's case so well that they would agree you've got it right. Then you engage that version. The goal is to test your own view against the best counterargument, not the worst. If you can defeat the steelman, your position is stronger. If you can't, you've learned something.
The term is the inverse of "strawman," the fallacy of misrepresenting a position to make it easy to knock down. Steelmanning is the antidote. It forces you to inhabit the other view, to marshal its best evidence and reasoning. That discipline improves decision quality: you avoid the overconfidence that comes from beating up weak versions. It also improves persuasion. When you steelman before you disagree, you show you've listened. The other side is more likely to engage when they feel understood. Negotiations and debates move from posturing to problem-solving when each side can articulate the other's best case.
Steelmanning does not require you to agree. It requires you to represent the opposing view at its strongest, then to test it. In strategy, steelman the case for the competitor's success before you dismiss it. In hiring, steelman the case against the candidate before you decide. In investing, steelman the bear case before you buy. The result is either greater confidence in your thesis (you've stress-tested it) or a reason to revise (the steelman held up).
Section 2
How to See It
Steelmanning shows up wherever someone deliberately strengthens the other side's argument before responding, or where a process requires the best version of the counterview to be stated and addressed.
Debate
You're seeing Steelmanning when a debater opens by summarising the opposition's strongest points and concedes what is valid before making their own case. The audience hears both sides at full strength. The debater then addresses the steelman, not a caricature. The move signals intellectual honesty and raises the level of the exchange.
Strategy
You're seeing Steelmanning when a leadership team assigns someone to argue the case for a competing strategy or for the competitor winning. "Why might we be wrong? Why might they win?" The exercise produces a steelman of the alternative. Decisions that follow are made against that strong version, reducing the risk of groupthink and weak counterarguments.
Investing
You're seeing Steelmanning when an investor writes a full bear case before or after a conviction buy. The bear case is the steelman: the best argument for why the position could fail. If the investor can't articulate it, they haven't done the work. If they can articulate it and still hold, the position is stress-tested.
Negotiating
You're seeing Steelmanning when a negotiator restates the other party's position in terms the other party endorses — "So your concern is X, and you're asking for Y because Z" — before presenting their own. The restatement is the steelman. It confirms understanding and often surfaces the real interests behind positions, making agreement easier.
Section 3
How to Use It
Decision filter
"Before you reject a view, a deal, or a strategy, steelman it. State the best version of the opposing case. If you can't state it to the other side's satisfaction, you don't understand it yet. Only then argue or decide."
As a founder
Steelman the case against your company and your strategy. Why might the competitor win? Why might this market never materialise? Why might this hire be wrong? Build the steelman in writing or in a dedicated meeting. If your team can't build a plausible steelman, you may be in an echo chamber. If you can build it and still believe, your conviction is better founded. Use steelmanning in board and investor conversations: preempt the strongest objection and address it. You'll earn trust and sharpen the thesis.
As an investor
Before you invest, steelman the bear case. What would have to be true for this to be a bad investment? What does the smartest skeptic say? Write it down. If you can't articulate a strong bear case, you don't know the position well enough. If you can articulate it and still invest, you've done the work. Use the same discipline when you're skeptical: steelman the bull case before you pass. You might find you were wrong.
As a decision-maker
In any material decision, assign someone to argue the best version of the alternative. Don't let the dominant view go unchallenged by a weak counter. Require a steelman: the strongest case for the path you're not taking. Then decide against that. The quality of decisions improves when the counterargument is strong, not when it's easy to dismiss.
Common misapplication: Using steelmanning to avoid taking a position. Steelmanning is a step, not the end. You build the steelman to test your view, then you decide. Endless steelmanning without conclusion is indecision. Use it to stress-test, then commit or revise.
Second misapplication: Pretending to steelman while subtly weakening the other side. A fake steelman is still a strawman. The test: would the other side agree that you've stated their case fairly and at full strength? If not, you're not steelmanning. Ask them to correct your summary until they agree.

The Mechanism
Section 5
Founders & Leaders in Action
Peter ThielCo-founder, PayPal & Palantir; Partner, Founders Fund
Thiel pushes founders to ask: "What important truth do few people agree with you on?" That question forces you to steelman the consensus before you disagree. To hold a contrarian view, you must understand the best case for the mainstream view and then see why it might be wrong. Thiel's discipline is to take the crowd's position seriously — to state it at full strength — before betting against it.
Charlie MungerVice Chairman, Berkshire Hathaway, 1978–2023
Munger repeatedly advises inverting and arguing against yourself. "I never allow myself to have an opinion on anything that I don't know the other side's argument better than they do." That is steelmanning: knowing the other side's best case so well that you can make it better than they can. He uses it in investing — understand the bear case before you buy — and in life. The discipline is to steelman the opposition before you commit.
Section 6
Visual Explanation
Steelmanning: build the strongest version of the opposing view before you engage. If you can defeat the steelman, your position is stronger; if not, you learn. Avoid the strawman — the weak version that is easy to knock down.
Section 7
Connected Models
Steelmanning connects to how we test ideas, avoid bias, and persuade. The models below either complement it (Red Team, Scout Mindset), explain why we don't do it (Confirmation Bias), or provide methods for doing it well (Socratic Method, Common Ground).
Reinforces
Red Team
Red teams are assigned to argue against the plan. That is institutionalised steelmanning: the red team builds the strongest case for failure or for the adversary. Steelmanning is the individual habit; red teaming is the organisational practice. Both force the best counterargument into the room before the decision is made.
Reinforces
Scout Mindset
Scout mindset is the motivation to see things as they are, not as you wish. Steelmanning is a tactic for scouts: you deliberately strengthen the other view to get a more accurate picture. Both reduce the distortion of motivated reasoning. Scouts steelman; soldiers strawman.
Reinforces
Confirmation Bias
Confirmation bias is the tendency to seek and overweight evidence that supports your view. Steelmanning is a corrective: you actively seek and state the best evidence for the opposite view. The discipline counteracts the bias by making the countercase salient and strong before you decide.
Leads-to
The Socratic Method
Socratic method probes a position by questioning. Steelmanning can be part of it: "What's the strongest version of the view you oppose?" or "How would you state my view at its best?" Both aim at clarity and stress-testing. Use Socratic questioning to build and refine the steelman with the other party.
Section 8
One Key Quote
"He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion."
— John Stuart Mill, On Liberty (1859)
Mill's point is that you don't really know your own view until you know the best case against it. Steelmanning is the practice that implements this: you build and engage the best opposite case. If you can't refute the steelman, you have no ground for your preference. If you can, your preference is better grounded.
Section 9
Analyst's Take
Faster Than Normal — Editorial View
Steelman before you disagree. In meetings, in writing, in negotiations — state the other side's best case first. The test: would they agree you've got it right? If not, you're still strawmanning. Once you've steelmanned, your objection carries more weight because you've shown you understand. The other side is more likely to listen when they've been heard.
Use it in strategy and investing. Before you commit to a strategy, steelman the case for the competitor winning or for the market failing. Before you invest, steelman the bear case. Write it down. If you can't write a convincing steelman, you don't know the situation well enough. If you can write it and still commit, your conviction is stress-tested.
Assign a steelman in decisions. For any material decision, assign someone to argue the best version of the alternative. Don't leave it to the room to weakly dismiss the counterview. Require a document or a presentation: "Here is the strongest case for the path we're not taking." Then decide against that. The quality of the decision tracks the strength of the counterargument you've considered.
Don't use steelmanning to dodge. The point is to test your view and then decide, not to stay in permanent doubt. Build the steelman, engage it, then commit or revise. Endless "both sides" without conclusion is indecision, not wisdom.
Steelmanning builds trust. When you represent the other view well, you signal respect and intellectual honesty. That makes persuasion more likely when you do disagree. In negotiations, restating the other party's position to their satisfaction before you present yours is a form of steelmanning that often unlocks agreement.

Test Yourself
Is this mental model at work here?
Scenario 1
Before a board vote on a major acquisition, the CEO asks the CFO to present the strongest case against the deal, as if arguing to kill it.
Scenario 2
A debater summarises the other side's argument in a way that makes it sound silly, then easily refutes it.
Scenario 3
An investor writes a one-page 'bear case' for a stock they own, listing the best arguments for why the position could fail, then explains why they still hold.
Scenario 4
In a negotiation, one party says: 'So if I understand you, you need X because of Y, and the blocker is Z. Is that right?' before making their own proposal.
Section 11
Summary & Further Reading
Summary: Steelmanning is building the strongest plausible version of an opposing view before you engage it. It is the opposite of strawmanning. Use it to stress-test your own position, to improve decisions by considering the best counterargument, and to persuade by showing you've understood the other side. Assign steelmans in strategy and investing; state the other side's case to their satisfaction in debate and negotiation. Then decide or respond. The discipline increases both accuracy and trust.

[Common Ground](/mental-models/common-ground)
Before you disagree, find what you share. Steelmanning helps: when you state the other side's case well, you often surface shared premises or goals. The disagreement narrows to a crux. Common ground is where you start; steelmanning is how you represent their view so you can find it.
Tension
[Motte and Bailey](/mental-models/motte-and-bailey)
Motte and bailey is a rhetorical move: defend a strong claim (bailey) by retreating to a weak one (motte) when challenged. Steelmanning does the opposite — you engage the strong version. The tension: if someone uses motte and bailey, steelmanning their bailey (the strong claim) is the right response. Don't let them retreat to the motte; insist on engaging the steelman of the bold position.
