LSAT Logical Reasoning: Method of Reasoning

Rank 9 by frequency | 215 questions in corpus (4.7% of all questions)

Method of Reasoning questions ask you to describe how an argument is constructed — what technique, strategy, or logical move the author uses. You are not evaluating whether the reasoning is good or bad; you are accurately describing what the argument is doing. The correct answer is always an abstract description of the argumentative move, and every element of that description must be verifiable against the stimulus.

What You'll Learn How Method questions ask about the technique an argument uses, not whether the argument works. The vocabulary of common argumentative moves — counterexample, analogy, appeal to authority, rule-application, drawing a distinction, elimination. The step-by-step method for mapping argument structure before matching it to an abstract description. How correct answers are built through the Fact Test. The common traps LSAC uses most often — and what makes the hardest versions hardest.

What the Question Asks

Method of Reasoning is a purely descriptive question type. You are not asked whether the argument is good, whether it has a flaw, or whether the conclusion is true. You are asked one question: what is the argument doing? This is a fundamentally different cognitive mode from most LR questions, which reward you for evaluating reasoning. Here, evaluation is irrelevant — the argument might be airtight or wildly fallacious, and the correct answer describes its technique either way.

The skill being tested is reading for structure rather than content. You must see past what the argument is about — homelessness, ancient pottery, tax policy — and recognize what the argument is doing: drawing an analogy, eliminating alternatives, conceding a point. That requires fluency with abstract argumentative vocabulary and the ability to translate between a concrete argument and its abstract characterization.

Because the answer is always explicit in the stimulus, every correct answer must pass the Fact Test: every element of the description must be verifiable directly in the text. You cannot add anything the stimulus does not support, and you cannot leave out anything the description claims is there.

Common Argumentative Moves

Before you can identify a method, you need a vocabulary of possible methods. Almost every LR argument uses one of the moves below. The correct answer will describe one of them in abstract structural language — rarely using these exact labels, but always expressing the same underlying idea.

Counterexample. Refuting a general claim by citing a specific case that contradicts it. "All X are Y" is countered with "Here is an X that is not Y."

Analogy. Comparing two situations to argue they should have similar outcomes. Often phrased in answer choices as "draws an analogy between two cases."

Appeal to authority. Citing expert opinion or research findings as the basis for a conclusion.

Rule-application. Taking an abstract principle and applying it to a specific case. Answer-choice language: "applies a general principle to a particular situation."

Drawing a distinction. Pointing out a relevant difference between two things, often to show that a rule that applies to one does not apply to the other.

Alternative explanation. Proposing a different cause or reason for the same evidence. Common in dialogue formats where Speaker B responds to Speaker A.

Eliminating alternatives. Ruling out other possibilities to support the remaining one. Often called "argues by elimination."

Generalization. Drawing a broad conclusion from particular examples — the inverse of counterexample.

Reductio ad absurdum. Showing that a position leads to absurd consequences in order to reject it.

Challenging an assumption. Questioning an unstated premise the argument relies on.

Questioning relevance. Arguing that the evidence offered does not actually bear on the conclusion — a subtle move different from disputing the evidence itself.

Concession. Accepting something the opponent says but arguing that it does not affect the main point.

Citing a phenomenon to be explained. Presenting an observation and then proposing an explanation — the classic hypothesis structure.

Within any of these moves, four structural elements appear: background (orienting information that does not participate in support), premises (support-givers), subsidiary or intermediate conclusions (statements that both receive and give support), and the main conclusion (the tip of the pyramid — receives support but gives none). The method is the pattern by which these elements connect.

The Variations You'll See

Method of Reasoning appears in two major formats. A small number of stems overlap with Identify the Role, which is closely related but technically separate.

Variation 1 — Whole-argument method (single speaker). You are asked to describe the overall technique used across the entire argument. Stems include "The argument proceeds by...", "Which one of the following most accurately describes the method of reasoning used in the argument?", "The argumentative strategy of the investigator is to...", "In the passage, the author does which one of the following?", and "Which one of the following argumentative techniques does [person] use?"

Variation 2 — Dialogue method (response technique). Two speakers: Speaker A makes a claim, Speaker B responds, and you must identify the technique Speaker B uses to engage with Speaker A's argument. Stems include "[Person B] responds to [Person A]'s claim by...", "Which one of the following most accurately expresses the grounds on which [Person B] criticizes [Person A]'s reasoning?", "[Person B] challenges [Person A]'s reasoning by...", and "[Person B] counters [Person A] by doing which one of the following?"

Closely related — Identify the Role. Technically a separate type, Identify the Role uses similar stems but zooms in on a single quoted statement rather than the whole argument. "The claim that [quoted statement] plays which one of the following roles in the argument?" If the stem quotes a specific statement, you are in Role territory, not Method.

How to Approach the Question

A consistent approach works on every Method question. The principle is: map the argument's structure before you look at the abstract descriptions in the answer choices.

Step 1 — Identify every structural component. What is background context? What are the premises? Are there intermediate conclusions? What is the main conclusion? In dialogue format, do this separately for each speaker — find each person's conclusion and evidence.

Step 2 — Characterize the move in your own words. Before looking at the answer choices, ask: what is this argument DOING? Try to describe it abstractly: "The author gives a specific example to counter a general claim," or "Speaker B offers a different explanation for the same evidence," or "The argument eliminates other possibilities to support its conclusion."

Step 3 — Match your prediction to the choices. The correct answer will express the same idea using more abstract vocabulary. If your prediction was "gives an example that contradicts a general rule," look for "provides a counterexample to a general claim."

Step 4 — De-abstract every candidate answer. Replace every abstract term in the answer with the specific content from the stimulus. If the resulting concrete statement is accurate about the stimulus, the answer is correct. If any element does not match, eliminate.

How the Correct Answer Is Built

Every correct Method answer has two defining features. First, it uses abstract language exclusively — never referring to the specific subject matter. You will see general terms like a claim, an example, a generalization, evidence, a principle, a counterexample, an alternative explanation. You will not see the actual topic of the argument.

Second, every element is factually accurate about the stimulus. If the answer says "provides a counterexample to a general claim," then (a) there must be a general claim in the stimulus, and (b) the author must actually provide a case that contradicts it. The Fact Test applies to every clause: nothing in the answer can describe something that did not happen.

The correct answer does not have to be the most comprehensive description possible — just an accurate one. A description that captures the main move without cataloging every sub-step can still be correct if everything it says is true of the stimulus.

Common Wrong-Answer Traps

Wrong answers on Method questions cluster around a few predictable shapes.

Trap 1 — Technique never employed. The answer describes a reasoning move that simply does not appear in the stimulus. The argument does not use an analogy, but the answer says it does. This is the most basic wrong answer — you catch it by de-abstracting the choice and checking whether the described move actually occurred.

Trap 2 — Mislabeled structural elements. The answer correctly identifies that a technique was used but mislabels the roles of the components — describing the conclusion as a premise, a premise as the conclusion, a subsidiary conclusion as the main conclusion, background as a premise, or a straightforward claim as a "phenomenon." This trap looks right on a quick read; you catch it by verifying that each component is correctly identified.

Trap 3 — Accurate in part, wrong in another. The answer correctly describes one part of the argument but inaccurately describes another. Every clause has to pass the Fact Test — one wrong element invalidates the whole answer no matter how accurate the rest.

Trap 4 — Describes the content, not the structure. The answer describes what the argument is about rather than what it is doing. Method is always about structure, never content.

Trap 5 — Sounds impressive but fails verification. Uses sophisticated-sounding abstract vocabulary that contains factual errors about the stimulus. The trap exploits the tendency to be impressed by "LSAT-like" phrasing. Always de-abstract and verify.

What Makes the Hardest Versions Hard

Two features drive difficulty on Method questions, and LSAC combines them to build the hardest versions.

Complex, multi-layered arguments. The stimulus contains background, premises, one or more subsidiary conclusions, and a main conclusion. Parsing the structure correctly is the primary challenge — if you miss a subsidiary conclusion or confuse background for a premise, every answer choice will look equally plausible.

Subtle technique distinctions. The technique is not obvious — it requires careful analysis to recognize what is being done. A classic distinction: the author "questions the relevance of the evidence to the conclusion" versus "disputes the evidence" itself. These sound similar but describe very different moves. Hard questions live in these subtle distinctions, and two answer choices will usually capture opposite sides of one.

How It Differs from Similar Types

Method questions share surface features with several other types. Keeping the distinctions clear prevents you from applying the wrong strategy.

vs. Flaw. Method asks what the argument DOES; Flaw asks what the argument does WRONG. Method is neutral/descriptive ("The argument proceeds by..."); Flaw is critical/evaluative ("The argument is most vulnerable to criticism on the grounds that..."). A Method answer may describe a valid or a flawed technique — you don't judge the quality. A Flaw answer always identifies a quality failure.

vs. Identify the Role. Role zooms in on one specific quoted statement's function within the argument. Method describes the overall technique of the entire argument. If the stem quotes a specific claim, you are in Role; if it asks about the whole argument's strategy, you are in Method.

vs. Match the Reasoning. Method asks you to DESCRIBE how the argument proceeds in abstract terms. Match asks you to FIND another argument that proceeds the same way. Method is analytical within one argument; Match is comparative across two.

Question Stems You'll See

Every Method question uses one of the stem patterns below. Recognizing them instantly tells you to switch into structural-analysis mode: map the argument first, then match to the abstract description.

  • "The argument proceeds by..."
  • "Which one of the following most accurately describes the method of reasoning used in the argument?"
  • "The argumentative strategy of the investigator is to..."
  • "In the passage, the author does which one of the following?"
  • "Which one of the following argumentative techniques does [person] use?"
  • "[Person B] responds to [Person A]'s claim by..."
  • "Which one of the following most accurately expresses the grounds on which [Person B] criticizes [Person A]'s reasoning?"
  • "[Person B] challenges [Person A]'s reasoning by..."
  • "[Person B] counters [Person A] by doing which one of the following?"
