Two LSAT question types, named almost identically.
One word separates the answer families.
Two LSAT question types named almost identically. Different right answers, different distractor families. The structural lens that separates them.
Key takeaway
What to remember about Method of Argument vs Method of Reasoning
Method-of-Argument asks what rhetorical move the arguer makes. Method-of-Reasoning asks what inferential structure the arguer uses. The two stems look almost identical and the wrong-answer families overlap. A two-step read separates them: first tag the stem, then label the move at the rhetorical level or the structural level before scanning answers.

Method-of-Argument and Method-of-Reasoning are two LSAT Logical Reasoning question types named almost identically. The stems differ by one word. The right answers come from different families. A student who treats the two as one type picks a structurally correct answer to the wrong question, and the answer reads right on review.
The cost is not a knowledge gap. The stimulus was read correctly. The argument was understood. The answer chosen described the argument accurately. It described the argument at the wrong altitude.
Argument names the rhetorical move. Reasoning names the inferential structure.
Why one word changes the answer family
Method-of-Argument stems describe what the arguer does as a speaker. The stems read "the argument proceeds by," "the author responds to the opposing view by," and "the argument develops through the use of." The right answer names a rhetorical move. "Citing an authority." "Drawing an analogy." "Conceding a point and redirecting." "Distinguishing a case." These are moves a speaker makes during a debate. They describe how the arguer is talking, not how the arguer is thinking.
Method-of-Reasoning stems describe the inferential machine. The stems read "the argument uses which one of the following techniques," "the reasoning in the argument is best described as," and "the argument relies on which principle of inference." The right answer names a structural pattern. "Generalizing from a sample." "Inferring a cause from a correlation." "Applying a rule to a case." "Reasoning by elimination."
The two altitudes use overlapping vocabulary in the wrong answers. "Citing evidence" can appear as a wrong answer on a Method-of-Reasoning item because it is true of the argument but not the structure. "Generalizing from a sample" can appear as a wrong answer on a Method-of-Argument item because it is structurally accurate but not the rhetorical move.
Either 'argument' or 'reasoning.' The stem keyword is the answer family.

Three patterns of miss
Method misses cluster around three altitude errors. Each error reads as a real mistake on review because the wrong answer is true of the argument. The fix is altitude discipline.
- Altitude collapse. A student reads the stem as a single 'method' family. Fix: highlight the word 'argument' or 'reasoning' on first stem read. The keyword is the question type.
- Truth-not-altitude. A student picks the answer that is true of the argument. Fix: pick the answer at the right altitude even if a truer claim at the wrong altitude sits in the choices.
- Vocabulary overlap. A student eliminates by surface content match. Fix: eliminate by altitude match. Trap answers match content; right answers match altitude.
This post connects to Method of Reasoning and Flaw. Flaw questions test the same altitude discipline because identifying a flaw requires naming the inferential move the argument makes badly. The skill map drills these in sequence.
A real method drilling plan
The plan is two weeks. Separate blocks first, then mixed. Separate blocks build the altitude reflex. Mixed blocks test it under switching cost. Most of the score gain on Method items lands in the second week.
| Read the stem as a single "method" family. | Tag the stem as Method-of-Argument or Method-of-Reasoning. The keyword is the word that follows "method of." | The two types pull from different answer pools. Tagging the type tells you which pool to search. |
| Pick the answer that is true of the argument. | Pick the answer at the right altitude. Rhetorical on Method-of-Argument. Inferential on Method-of-Reasoning. | Multiple answers will be true of the argument. Only one will be at the altitude the stem asks for. |
| Drill the two types in one mixed block. | Drill the two types in separate blocks for one week, then mixed for the next week. | Separate blocks build the altitude reflex. Mixed blocks test it under switching cost. Sequence matters; reversed order trains a weaker reflex. |
The worked example
Pinaka does not yet have a Method-specific worked example in this set. The Flaw walkthrough below demonstrates the altitude discipline that transfers to both Method types.
The question below is a Flaw item. The altitude discipline transfers. To name a flaw, you first name the inferential move the argument is making. If the move is "generalizing from a sample," the flaw is in the sample. If the move is "inferring a cause from a correlation," the flaw is in the inference. The altitude tag that separates Method-of-Argument from Method-of-Reasoning lands the same way here.
Maya argues that the inventory-forecasting tool used at Pinaka Books cannot be responsible for last quarter's stockouts. The tool, she explains, is just an algorithm that outputs whatever it is given; therefore the errors lie entirely with Sam, who entered the sales data.
The argument above is most vulnerable to criticism on which one of the following grounds?
Maya slides from "the tool has no agency" to "the tool contributed nothing." Tools with built-in assumptions still shape outputs. Option (D) names the slide.
This is a Flaw question, specifically equivocation. Maya’s argument: the tool just outputs what it gets, so the error is on Sam. The structural gap: tools embed assumptions and can shape errors independently of inputs. Look for the option that names this leap.
For Flaw questions, the right answer captures the conceptual conflation that licenses the conclusion. Real-world worries and side issues are common traps; structural diagnosis is the target.
60-90 seconds. Cut (B) and (C) on out-of-scope quickly. (A) and (E) are real-world worries that do not name the structural leap. (D) is the only structural answer.
Common questions
What is the difference between Method of Argument and Method of Reasoning?
Method of Argument asks what rhetorical move the author makes (cites evidence, draws an analogy, concedes a point). Method of Reasoning asks how the argument moves from premise to conclusion (generalizes, infers, contrasts). The first is rhetorical; the second is inferential.
How do I tell which Method type a question is asking?
Read the word that follows "method of." Argument means rhetorical altitude. Reasoning means inferential altitude. Tag the altitude before reading the answer choices.
Are Method questions common on the LSAT?
They appear in modern Logical Reasoning sections at a moderate frequency. The Method family sits inside the meta-LR group along with Main Point, Role in Argument, and the speaker-disagreement stems.
Should I drill Method types together or separately?
Drill them in separate blocks for the first week to build the altitude reflex. Then drill them in mixed blocks to test the reflex under switching cost. Sequence matters; mixing too early trains a weaker reflex.
Next steps
Match the altitude before scanning answers.
Find the word that follows "method of." Argument or reasoning. Tag it. Two altitudes. One question. Match before scanning.
