Argument Structure
Toulmin Model of Argumentation
ARGUMENT BUILDER (Toulmin Model):
CLAIM: [Your main assertion]
What are you arguing?
GROUNDS: [Evidence and data supporting the claim]
What facts back this up?
WARRANT: [The logical connection between grounds and claim]
Why does this evidence support your claim?
BACKING: [Support for the warrant itself]
Why should we trust this reasoning?
QUALIFIER: [Degree of certainty — most, some, probably]
How strong is this claim?
REBUTTAL: [Conditions where the claim doesn't hold]
When would this argument fail?
EXAMPLE:
Claim: "Remote work increases productivity for knowledge workers."
Grounds: "Stanford study showed 13% productivity increase in remote workers."
Warrant: "Fewer interruptions and commute elimination allow deeper focus."
Backing: "Multiple studies confirm interruptions cost 23 min to recover from."
Qualifier: "For most knowledge workers in roles not requiring physical presence."
Rebuttal: "May not apply to new employees needing mentorship or highly
collaborative creative roles."
Argument Types
| Type | Structure | Best For | Example |
|---|---|---|---|
| Deductive | If premises true → conclusion must be true | Logical proofs, policy arguments | "All citizens must follow laws. X is a citizen. Therefore X must follow laws." |
| Inductive | Specific observations → general conclusion | Scientific arguments, trend analysis | "In 50 studies, X led to Y. Therefore X likely causes Y." |
| Abductive | Best available explanation | Diagnostic arguments | "The best explanation for these symptoms is condition X." |
| Analogical | Similar case → similar conclusion | Precedent-based arguments | "Policy X worked in Country A, which shares characteristics with Country B." |
| Causal | X causes Y | Policy proposals, problem-solution | "Increasing minimum wage will reduce poverty because..." |
Counterargument Generation
Counterargument Framework
COUNTERARGUMENT WORKSHEET:
ORIGINAL ARGUMENT: [State the argument you're opposing]
STRATEGY 1 — CHALLENGE THE EVIDENCE:
"The evidence cited is flawed because..."
- Data is outdated: [Explain]
- Sample size insufficient: [Explain]
- Source is biased: [Explain]
- Correlation ≠ causation: [Explain]
STRATEGY 2 — CHALLENGE THE REASONING:
"Even if the evidence is correct, the conclusion doesn't follow because..."
- Logical gap between evidence and claim: [Explain]
- Alternative explanation for the data: [Explain]
- False dichotomy (there are other options): [Explain]
STRATEGY 3 — CHALLENGE THE SIGNIFICANCE:
"Even if the argument is valid, it doesn't matter because..."
- The impact is overstated: [Explain]
- Other factors are more important: [Explain]
- The cost of the proposal outweighs the benefit: [Explain]
STRATEGY 4 — PROVIDE COUNTEREXAMPLES:
"This argument fails in these real-world cases..."
- Example 1: [Where the argument doesn't hold]
- Example 2: [Where the opposite occurred]
STRONGEST COUNTER: [Select best strategy + compose your response]
Steel Man Technique
STEEL MAN PROCESS:
Before arguing against a position, first construct the STRONGEST
possible version of your opponent's argument:
STEP 1: State their argument in your own words
"[Opponent's position as I understand it]"
STEP 2: Check understanding
"Is this a fair representation of your view?"
STEP 3: Strengthen it (add their best evidence)
"In fact, the strongest version of this argument would include..."
- Best available evidence for their position
- Most charitable interpretation of their claims
- Strongest logical chain supporting their conclusion
STEP 4: NOW respond to the strongest version
"Even in its strongest form, this argument has the following problems..."
WHY STEEL MAN:
- Demonstrates intellectual honesty
- Prevents straw man fallacy
- Your counter is more persuasive when addressing the best version
- Builds credibility with the audience
- Forces you to deeply understand the issue
Logical Fallacies Reference
Common Fallacies
| Fallacy | Definition | Example | Response |
|---|---|---|---|
| Ad Hominem | Attacking the person, not the argument | "You can't trust their economic analysis, they didn't finish college." | "The argument's validity is independent of who makes it. Let's examine the evidence." |
| Straw Man | Misrepresenting the argument to attack it | "You want to reduce military spending? So you don't care about national security?" | "That's not my position. I said [actual position]." |
| Appeal to Authority | Citing an authority outside their expertise | "A famous actor says vaccines are dangerous." | "What do the relevant experts (epidemiologists) say?" |
| False Dichotomy | Presenting only two options when more exist | "Either we ban all cars or accept pollution." | "There are many intermediate options: electric vehicles, public transit, emissions standards." |
| Slippery Slope | Claiming one event will inevitably lead to extreme outcomes | "If we allow X, next thing you know Y and Z will happen." | "What evidence exists that X actually leads to Y? Each step requires its own justification." |
| Circular Reasoning | Using the conclusion as a premise | "This policy is good because it's the right thing to do." | "You're assuming what you're trying to prove. Why is it the right thing?" |
| Red Herring | Introducing an irrelevant topic | "We should discuss education funding." "But what about the economy?" | "That's a separate issue. Let's stay focused on education funding." |
| Bandwagon | Appealing to popularity | "Everyone believes X, so X must be true." | "Popularity doesn't determine truth. What does the evidence show?" |
| Appeal to Emotion | Using emotion instead of logic | "Think of the children!" (without relevant evidence) | "I share your concern, but let's examine what the data actually shows." |
| Hasty Generalization | Drawing broad conclusions from limited examples | "I know two people who failed, so the program doesn't work." | "Two cases isn't enough to evaluate the program. What do the aggregate results show?" |
