LSAT Principle: Identify

Last updated: May 2, 2026

Principle: Identify questions are one of the highest-leverage areas to study for the LSAT. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.

The rule

An Identify-the-Principle question gives you a stimulus describing a specific judgment, action, or argument and asks you to pick the answer that states the general principle the stimulus illustrates or relies on. Your job is to translate the concrete case into a broader rule that (a) covers the case, (b) does not extend beyond what the case actually supports, and (c) matches the stimulus's logical direction (justifies the conclusion, rather than reversing or weakening it). Treat the stimulus as one application of a general rule, and pick the rule that fits cleanly.

Elements breakdown

Locate the judgment or conclusion

Find the specific claim, evaluation, or recommendation the stimulus makes — that is the thing the principle must justify or describe.

  • Find the recommendation, evaluation, or verdict
  • Identify who is doing what to whom
  • Note any praise, blame, or obligation language
  • Mark the trigger condition that produced the judgment

Abstract from concrete to general

Replace the stimulus's specific names, fields, and contexts with general categories, then state the rule that links the trigger to the judgment.

  • Strip proper nouns and field-specific terms
  • Substitute category words for examples
  • State rule as condition then evaluation
  • Keep the rule's scope as narrow as the case

Common examples:

  • 'Marta lied to her editor about her sources, so she should be fired' becomes 'employees who deceive supervisors about work product warrant termination'.

Match scope and strength

The correct principle must cover the case but not promise more than the case shows; check modal words like must, may, should, always, sometimes.

  • Check quantifier: all, most, some, none
  • Check modal: must, should, may, can
  • Check direction: requires versus permits
  • Reject answers narrower than the case
  • Reject answers broader than the case supports

Confirm the rule actually applies

Plug the stimulus back into the candidate principle and verify the trigger conditions are met and the judgment follows.

  • Verify the trigger fires in the stimulus
  • Verify the principle yields the same verdict
  • Reject principles whose trigger is absent
  • Reject principles that yield a different verdict

Common patterns and traps

The Strength Mismatch Trap

The stimulus reaches a strong, unconditional verdict (the act was wrong, the policy is illegitimate), but the answer choice softens it to 'may be questionable' or 'is sometimes problematic.' Or the reverse: the stimulus offers a measured judgment and the answer choice converts it into an absolute rule. Strength has to match — a principle that is too weak fails to justify the verdict, and a principle that is too strong claims more than the stimulus supports.

An answer that begins 'A government always must…' when the stimulus criticized one specific lapse, or 'It is sometimes preferable to…' when the stimulus issued a categorical condemnation.

The Scope Creep Principle

The answer states a rule that is true and morally appealing but covers situations beyond the stimulus's concern. The principle would justify the conclusion, but it would also justify many other unrelated conclusions because its trigger is broader than what actually drove the judgment in the stimulus. Tempting because it 'feels right,' but it is not the principle the case illustrates.

An answer that talks about 'all institutions' or 'any decision affecting people' when the stimulus's reasoning turned on something narrower like procedural notice or a specific fiduciary role.

The Restatement Imposter

The answer is essentially the stimulus rewritten with a few synonyms — keeping all the specific actors and facts. It is not a principle at all; it is just the conclusion. A real principle has to be general enough to apply to other cases, not just the one in the stimulus.

An answer that names the same specific actors or domain as the stimulus (the same agency, the same profession, the same product) instead of generalizing them into categories.

The Reversed Conditional

The stimulus uses a rule of the form 'if X, then judgment Y,' but the answer choice gives the converse: 'if judgment Y, then X' — or 'X is required for Y' when the stimulus only said 'X yields Y.' The directionality is wrong, so even though the words look similar, the rule does not actually generate the stimulus's verdict from the stimulus's trigger.

An answer that frames the trigger as a guarantee of legitimacy ('public hearings make rules legitimate') when the stimulus only said the absence of hearings made one rule illegitimate.

The Unrelated-Trigger Principle

The answer states a real, defensible principle, but its trigger condition is something the stimulus never invoked. Plugging the stimulus into this principle, the 'if' clause is never satisfied, so the principle cannot be the one driving the case's judgment. Students pick it because it sounds reasonable in the abstract.

An answer that conditions on intent, on financial gain, or on harm when the stimulus's reasoning hinged on something else entirely (e.g., procedure or role).

How it works

Suppose the stimulus says: 'A city council enacted a curfew without holding any public hearings. Because residents had no chance to weigh in, the curfew is illegitimate.' The judgment is that the curfew is illegitimate; the trigger is the absence of public input before the rule was passed. To identify the principle, strip the specifics — curfew, residents, council — and state the rule abstractly: regulations adopted without giving affected people a chance to be heard are illegitimate. That principle covers the case, matches the conclusion's strength (illegitimate, full stop), and applies in the right direction. A wrong answer might widen the rule to 'all government action requires public hearings' (overreach beyond what the stimulus is about), or narrow it to 'curfews require hearings' (too specific to be a principle), or flip the direction by saying 'public hearings guarantee legitimacy' (a converse the stimulus did not assert).

Worked examples

Worked Example 1

Which one of the following principles is most clearly illustrated by the reviewer's reasoning?

  • A A journalist who praises a project should disclose any relationship that financially benefits her from that praise.
  • B A journalist's review is improper whenever it fails to mention all the people involved in the work being reviewed.
  • C A journalist evaluating a work should disclose any relationship that could reasonably appear to have influenced her assessment, even if it did not in fact do so. ✓ Correct
  • D A journalist whose family member is involved in the production of a work should refuse to review that work.
  • E A journalist's review is proper as long as she sincerely believes the praise or criticism she offers.

Why C is correct: The reviewer's verdict — improper — is triggered by the failure to disclose a relationship that could plausibly have shaped judgment, and explicitly does not depend on whether the relationship actually did shape it. Choice C captures exactly that trigger ('could reasonably appear to have influenced') and exactly that verdict ('should disclose'), and it generalizes from the specific newspaper-and-library case to any reviewer-and-work case. Plugging the stimulus into C yields the stimulus's conclusion.

Why each wrong choice fails:

  • A: The stimulus never says Fei Liu benefited financially from her review; the trigger is appearance of influence, not financial gain. This principle's trigger is absent in the case. (The Unrelated-Trigger Principle)
  • B: The stimulus does not say the review was improper because it omitted everyone involved — only because it omitted a specific relationship that could appear to bias the judgment. This rule is much broader than what the case supports. (The Scope Creep Principle)
  • D: The stimulus says disclosure was required, not refusal to review. This principle is stronger than the verdict the reviewer reached and would condemn even properly disclosed reviews. (The Strength Mismatch Trap)
  • E: This is the converse of the stimulus's reasoning. The reviewer expressly says sincerity does not save the review from impropriety, so a principle making sincerity sufficient for propriety contradicts the case. (The Reversed Conditional)
Worked Example 2

Which one of the following principles most helps to justify the administrator's decision?

  • A A medical professional whose outcomes fall below regional averages may have practice privileges revoked.
  • B An institution may withhold privileges from a member who repeatedly refuses to fulfill a duty that the institution's rules make mandatory for all members. ✓ Correct
  • C A surgeon should not have privileges revoked unless patients have been harmed by the surgeon's conduct.
  • D An institution must give a member at least one warning before revoking privileges for any infraction.
  • E A medical professional who has been the subject of a malpractice complaint may be denied renewal of privileges.

Why B is correct: The administrator's verdict — non-renewal — is grounded in a single fact: Dr. Okonkwo repeatedly refused to do something the bylaws make mandatory for all staff surgeons. Choice B abstracts that exact structure (institution, member, repeated refusal of a mandatory duty) into a general rule that yields permission to withhold privileges. It matches the stimulus's modal strength ('may') and direction (the rule licenses, rather than requires, the action).

Why each wrong choice fails:

  • A: The stimulus expressly says the surgeon's outcomes are above regional average, so the trigger 'fall below regional averages' is not satisfied. This principle could not generate the administrator's decision in this case. (The Unrelated-Trigger Principle)
  • C: This principle would actually forbid the administrator's decision, since no patient was harmed. It runs in the opposite direction of the conclusion. (The Reversed Conditional)
  • D: Nothing in the stimulus discusses warnings, and the administrator does not invoke any warning step. This principle adds a requirement that the case neither addresses nor satisfies. (The Scope Creep Principle)
  • E: The stimulus explicitly notes that Dr. Okonkwo has never been the subject of a malpractice complaint, so this principle's trigger is absent. It cannot justify the administrator's actual reasoning. (The Unrelated-Trigger Principle)
Worked Example 3

The curator's reasoning most closely conforms to which one of the following principles?

  • A An institution should retain any cultural object it has lawfully purchased, regardless of how the object was originally obtained.
  • B An institution holding a cultural object that was wrongfully taken from its place of origin should return it to that place, even when the institution itself acquired the object innocently. ✓ Correct
  • C An institution that purchases a cultural object in good faith is entitled to compensation if it later returns the object to its place of origin.
  • D An institution should not acquire any cultural object whose history of ownership cannot be fully traced.
  • E An institution that returns a cultural object to its place of origin demonstrates that the original taking of the object was wrongful.

Why B is correct: The curator concludes that the manuscript will be returned without compensation, despite the museum's lawful and innocent acquisition, because the original taking was wrongful. Choice B states exactly that rule: wrongful original taking triggers an obligation to return, and innocent acquisition by the current holder does not block that obligation. Plugging the case into B produces the curator's conclusion.

Why each wrong choice fails:

  • A: This principle is the opposite of the curator's reasoning — it would justify keeping the manuscript. The curator instead concludes the museum must return it. (The Reversed Conditional)
  • C: The curator says the manuscript will be returned 'without compensation,' so a principle entitling the museum to compensation contradicts the stated conclusion rather than supporting it. (The Reversed Conditional)
  • D: The stimulus does not say the museum erred by acquiring the manuscript or that institutions must avoid acquiring objects with murky histories; it says only that this object must now be returned. The principle imposes a duty the stimulus never invokes. (The Scope Creep Principle)
  • E: This reverses the order of reasoning: the curator infers the duty to return from the prior wrong, not the prior wrong from the act of returning. The stimulus does not treat returning as evidence of wrongfulness. (The Reversed Conditional)

Key distinction

Identify-the-Principle is the inverse of Apply-the-Principle: here the specific case is given and you find the general rule; in Apply, the rule is given and you find the case it justifies. Mixing the two leads you to pick answers that describe the conclusion in different words rather than answers that state a generalizable rule.

Summary

Pick the most general statement that, when applied to the stimulus's facts, produces exactly the stimulus's judgment — no more, no less.
