Principle and Analogy
Principle and analogy questions test applying rules, parallel reasoning, parallel flaws, abstract structure, conclusion matching, and relevant differences.
How to study for the LSAT
Use the current LSAC format as your map: make Logical Reasoning automatic, build passage structure habits, then rehearse timed sections and Argumentative Writing source use.
Core concepts
Concept 1
Principle and Analogy questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Principle
A principle is a general rule that can justify or guide a specific case.
Apply Rule
Apply-rule questions require matching the facts to the conditions and outcome of a principle.
Parallel Reasoning
Parallel reasoning asks for the answer with the same argument structure.
Parallel Flaw
Parallel flaw asks for the answer that commits the same reasoning error.
Abstract Structure
Abstract structure reduces content to relationships among evidence, assumption, and conclusion.
Match Conclusion
A parallel answer must match the role and strength of the original conclusion.
Role Consistency
Each answer part must play the same argumentative role as the matching original part.
Relevant Difference
A relevant difference breaks an analogy or principle application.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
