Steelmanning and Strawmanning: Building Arguments That Hold

Why defeating a weak version of someone's view proves nothing, and how restating the strongest version first makes your own arguments sharper and fairer.

A manager says, "We should review whether this deadline is realistic." A colleague replies, "So you want us to stop meeting deadlines?" The room nods, the manager becomes defensive, and the original question quietly disappears.

Nothing was refuted. A weaker claim was placed in the manager's mouth and then knocked down. This is a strawman, and its opposite, the steelman, is among the most useful habits a thinker can build.

What They Are

Strawmanning is arguing against a weakened or distorted version of what someone actually said. The name comes from a man built of straw: easy to set up, easy to knock down, and no one is beaten when he falls.

Steelmanning is the reverse. Before you respond to a view, you restate it in its strongest and fairest form, the version its most thoughtful defender would be proud of. Only then do you test it, accept it or reject it.

The idea is old. Thomas Aquinas began each question in his Summa Theologiae with the objections to his own position, stated at full strength, before giving his answer. John Stuart Mill argued that a person who knows only their own side of a case knows little even of that. And Charlie Munger is widely quoted as saying he would not allow himself an opinion unless he could state the other side's case better than its own defenders.

Why We Strawman

Most strawmanning is not malice. It is ease. A weak target is quick to beat, and winning feels like progress. We often meet the weakest version of an opposing view first, through the loudest voice or the shortest clip, and confirmation bias leaves us content to stop there. It also protects us: if the other view is foolish, we never have to ask whether we might be wrong.

The common methods are few:

  • Oversimplifying. "Review the deadline" becomes "abandon deadlines."
  • Pushing to the extreme. "Regulate boda boda operators" becomes "you want to destroy their livelihoods."
  • Attacking the weakest spokesperson and treating that person as the whole view.
  • Assuming the worst motive.
  • Quoting out of context.

One fairness: if a person really did make the weak argument, answering it is not a strawman. The fault lies in attacking what they did not claim.

The Steelman in Practice

The philosopher Daniel Dennett, drawing on the game theorist Anatol Rapoport, offers a simple routine:

  1. Restate the other person's position so clearly and fairly that they would say, "Thank you, I wish I had put it that way."
  2. List the points on which you agree.
  3. Name anything you have learned from their view.
  4. Only then say where you disagree.

In short, you earn the right to disagree by first showing that you have understood.

Take stricter rules for boda boda operators. A strawman of one side says, "They want to ban boda bodas and put thousands out of work." Its steelman says, "Road injuries involving motorcycles are high, and licensing, helmets and insurance could save lives without ending the trade." A strawman of the other side says, "They do not care how many people die." Its steelman says, "For many people this is the only accessible income, and rules that are costly or hard to meet may push operators into an unregulated space where safety gets worse."

Set the two steelmen side by side and the quarrel changes. It is no longer "you hate workers" against "you hate safety." It becomes a question evidence can answer: which rules reduce deaths without pricing people out of work?

Apply It to Yourself

Before you present a plan, ask what the strongest objection to it is, and answer that one rather than the easy one. If you cannot state the best case against your own view, you do not yet understand it well. An AI model is useful here: ask it for the strongest case against your position, then address that case. It is the "challenge me" template from the workspace piece, and it works because the tool has no stake in your being right.

Where It Runs Out

Steelmanning is a discipline, not a duty to agree. You may state a view in its strongest form and still reject it. Take care not to invent a better argument than the person made, which is another distortion, only a kinder one. The test is the same: would they recognise the view as their own? And because it takes time, keep it for the disagreements that matter.

Questions to Ask

  1. Could the person I disagree with read my summary and say, "yes, that is what I mean"?
  2. What is the strongest reason a thoughtful person might hold this view?
  3. What would change my mind?

The Lesson

The strawman wins the argument and loses the truth. You leave feeling right, having learned nothing. The steelman is harder and will sometimes change your mind. When it does not, your position is still stronger, because it has survived the best the other side could offer.

So the next time you are about to answer someone, pause for a moment and look at the version of their view you are about to attack. Is it theirs, or did you build it?
