| When you see this in a choice | What it usually means |
|---|
| “...because...” | The stated reason must be both true and legally determinative. A true-but-irrelevant reason fails; a right result on a wrong reason fails. |
| “...if...” | Tests sufficiency — the choice is correct only if that added fact, taken as true, would actually change the outcome and fits the facts. |
| “...unless...” | Correct only if the stated fact is the one and only thing that defeats the result. If other paths exist, eliminate it. |
| Absolute words: always, never, must, cannot, all, any | Usually wrong — the law runs on exceptions. Hedged choices (“generally,” “likely”) are often safer. |
| A choice that restates the standard, burden, or standard of review | If it misstates the rule, it is out — even if the result feels right. |
| A choice that adds or changes facts | Out. Decide on the facts given; do not assume facts not in the stem. |
| Two choices that say the same thing in different words | Both are wrong — they cannot both be the single best answer. |
| A choice that is accurate but answers a different question | Out. It must answer the call, not a neighboring issue. |
| If you see / the call says | Then |
|---|
| A choice begins with because and states a reason that is factually true but legally irrelevant to the procedural issue | Eliminate it — a correct outcome supported by the wrong rationale is still wrong on the MBE. |
| A choice begins with if and the conditional fact would not by itself dictate the result | Reject it; an if choice survives only when that single fact is the dispositive path to the answer. |
| A choice uses absolutes like always, never, must in every case, or cannot ever | Treat it as presumptively wrong — procedural rules are riddled with exceptions and discretion. |
| A choice says a 12(b)(6) dismissal is proper because the plaintiff’s evidence is weak or unlikely to be believed | Eliminate it — that confuses pleading with proof; a motion to dismiss tests only the sufficiency of the allegations, taken as true. |
| A choice resolves a diversity question by looking at where the events happened rather than the parties’ citizenship | Discard it; subject-matter jurisdiction in diversity turns on citizenship and amount in controversy, not the locus of the dispute (that is venue). |
| A choice treats supplemental jurisdiction as something that destroys or defeats diversity | Reject it — supplemental jurisdiction adds a claim that lacks an independent jurisdictional basis; it does not undo SMJ that already exists. |
| A choice denies personal jurisdiction solely because the defendant is an out-of-state resident | Eliminate it — PJ depends on minimum contacts and fairness, not mere non-residency. |
| A choice grants summary judgment while a genuine factual dispute is described, or resolves a credibility question | Reject it; summary judgment is improper where a reasonable jury could find for the non-movant, and the judge does not weigh credibility. |
| A choice cites the wrong actor for a ruling — e.g., the jury decides a question of law, or the judge decides a question reserved for the jury | Eliminate it as a mismatch of decision-maker. |
| A choice asserts a defense like improper venue or lack of personal jurisdiction is still available after the defendant filed a Rule 12 motion or answer omitting it | Discard it — those waivable defenses are lost if not consolidated into the first Rule 12 response. |
| The trap | The fix |
|---|
| Conflating personal jurisdiction with venue — the question describes where it would be convenient to sue, hoping you pick a PJ answer. | Ask separately: does the forum have power over this defendant (PJ), and is this the right judicial district (venue)? They are independent inquiries. |
| Treating supplemental jurisdiction as a way to defeat diversity or as automatically available against an added defendant. | Remember the 1367(b) limitation: in diversity cases, plaintiffs cannot use supplemental jurisdiction to circumvent the complete-diversity requirement against parties joined under certain rules. |
| Mistaking the amount in controversy rules — e.g., letting unrelated plaintiffs aggregate small claims, or counting a single plaintiff’s claims wrong. | A single plaintiff may aggregate all claims against one defendant; separate plaintiffs generally may not aggregate unless asserting a common undivided interest. |
| Applying the wrong standard on a dispositive motion — testing evidence at the 12(b)(6) stage or testing pleadings at summary judgment. | Map the motion to its standard: 12(b)(6) accepts well-pleaded facts as true; summary judgment requires no genuine dispute of material fact on the evidentiary record. |
| Missing an Erie problem — a federal court sitting in diversity must apply state substantive law, but the question dresses up a substantive rule as procedural. | Distinguish substance (apply state law) from procedure (apply federal rules); statutes of limitations and tolling are typically substantive for Erie. |
| Overlooking waiver of the disfavored defenses — lack of PJ, improper venue, insufficient process or service. | These must be raised in the first Rule 12 motion or responsive pleading or they are forfeited; SMJ and failure to state a claim are not so easily waived. |
| Confusing claim preclusion (res judicata) with issue preclusion (collateral estoppel). | Claim preclusion bars relitigating the same claim between the same parties after a final judgment on the merits; issue preclusion bars relitigating a specific issue actually litigated and necessary to the prior judgment. |
| Misapplying the relation-back doctrine to a late amendment adding a new party. | Relation back for a new party requires the same transaction plus that the new party knew, within the service period, that the suit would have been brought against it but for a mistake. |
| Granting or denying a motion for judgment as a matter of law (JMOL/Rule 50) without checking whether it was preserved. | A renewed JMOL after the verdict is available only if the party first moved for JMOL before the case went to the jury. |
| Choosing an answer that is a correct statement of law but does not respond to the call of the question (e.g., it explains why a different motion would fail). | Re-anchor to exactly what was asked — the best ruling on this motion by this court — before selecting. |
| If you see / the call says | Then |
|---|
| A choice applies rational basis where the facts trigger strict or intermediate scrutiny (e.g., a race classification or a content-based speech restriction) | Eliminate it — the wrong tier almost always yields the wrong outcome and is a signature MBE distractor. |
| A choice begins with because and the stated reason invokes a right or clause not actually implicated | Reject it; a true-sounding rationale tied to the wrong provision still fails. |
| A choice begins with if and the conditional fact would not alone decide the constitutional question | Eliminate unless that fact is the sole dispositive hinge. |
| A choice uses absolutes such as always unconstitutional, never permissible, or government may not under any circumstances | Treat as suspect — nearly every constitutional rule yields to a sufficiently compelling interest or recognized exception. |
| A choice assigns the burden of proof to the wrong party for the applicable tier | Discard it — under heightened scrutiny the government must justify the law; under rational basis the challenger must negate every conceivable basis. |
| A choice reaches the merits when the plaintiff plainly lacks standing or the issue is moot/unripe | Eliminate it; a justiciability defect is resolved before the substantive question. |
| A choice treats purely private discrimination or conduct as a constitutional violation with no state-action hook | Reject it unless an entanglement, public-function, or coercion theory is supplied. |
| A choice upholds a content-based speech restriction merely because the speech is offensive or unpopular | Eliminate it — offensiveness is not a permissible ground; only narrow unprotected categories or strict-scrutiny justifications work. |
| A choice analyzes a state law burdening interstate commerce without separating the dormant Commerce Clause question (discrimination vs. mere burden) from preemption | Be wary — discriminatory laws face near-fatal scrutiny while nondiscriminatory burdens get the Pike balancing test. |
| A choice invokes substantive due process to strike economic regulation under heightened review | Reject it — ordinary economic and social legislation gets only rational basis; heightened review is reserved for fundamental rights. |
| The trap | The fix |
|---|
| Jumping to the merits while ignoring standing — the question gives a sympathetic plaintiff who has suffered no concrete, particularized injury. | Require injury-in-fact, causation, and redressability before any merits analysis; a generalized grievance or a third party’s rights usually defeats standing. |
| Missing the absence of state action — a private employer, club, or company is dressed up as a rights violator. | Look for a government actor or a recognized exception (public function, significant state entanglement); without it, the constitutional claim fails at the door. |
| Applying rational basis to a classification that is actually suspect or quasi-suspect (race, national origin, alienage; or sex/legitimacy). | Identify the classification first — race triggers strict scrutiny, sex triggers intermediate scrutiny — then the tier follows automatically. |
| Confusing the Privileges and Immunities Clause of Article IV with the Fourteenth Amendment privileges-or-immunities or with the dormant Commerce Clause. | Article IV protects out-of-state citizens (individuals, not corporations) from discrimination as to fundamental activities; the dormant Commerce Clause protects interstate commerce and reaches corporations. |
| Treating any law that incidentally affects religion as a Free Exercise violation. | A neutral law of general applicability that incidentally burdens religion is generally valid; heightened review applies when the law targets religious practice. |
| Overreading the Takings Clause — assuming every regulation that lowers property value is a compensable taking. | A regulation is a taking only if it denies all economically viable use or fails the regulatory-takings balancing; mere diminution in value is not enough. |
| Misjudging the dormant Commerce Clause — failing to spot facial discrimination against out-of-state actors. | Discriminatory state laws are virtually per se invalid absent a compelling justification with no nondiscriminatory alternative; evenhanded laws get Pike balancing. |
| Ignoring the market-participant exception when a state acts as a buyer or seller rather than a regulator. | When the state itself participates in the market, it may favor its own residents without dormant Commerce Clause violation. |
| Confusing the Establishment Clause with the Free Exercise Clause, or applying an outdated test to a clearly governing modern standard. | Frame government endorsement/coercion or historical-practice issues as Establishment, and government burdens on individual religious conduct as Free Exercise. |
| Picking the most fair-sounding outcome rather than the constitutionally required one. | Constitutional Law rewards the doctrinally correct result, not the sympathetic one; lock to the standard of review and let it dictate the answer. |
| If you see / the call says | Then |
|---|
| a choice gives a reason introduced by because that is factually true but legally beside the point | Eliminate it. A true-but-irrelevant rationale is the most common wrong answer; the reason must actually drive the outcome, not merely be accurate. |
| a choice uses an absolute like always, never, automatically, or cannot under any circumstances | Treat it as presumptively wrong. Criminal doctrine is riddled with exceptions, so categorical answers rarely survive. |
| a choice applies specific-intent logic (e.g., lets voluntary intoxication or unreasonable mistake excuse the defendant) to a general-intent crime like battery or rape | Eliminate it. Those defenses negate only specific intent; for general-intent crimes they are irrelevant. |
| a felony-murder choice demands that the death be foreseeable or that the defendant intended the killing | Be suspicious. Classic felony murder needs no intent to kill and imports no freestanding foreseeability test beyond proximate cause during a qualifying felony — a choice that adds one usually misstates the rule. |
| a Procedure choice says evidence is suppressed as fruit of a Miranda violation when the item is physical evidence or a later voluntary statement | Eliminate it. A bare Miranda violation generally does not require suppressing nontestimonial physical fruits; do not treat Miranda like the full 4th Amendment exclusionary rule. |
| a choice misstates the self-defense standard — allowing deadly force against a nondeadly threat, or requiring retreat in a no-retreat jurisdiction | Eliminate it. Force must be proportional and the retreat rule depends on the stated jurisdiction; a choice that warps either element is out. |
| a choice resolves an impossibility defense by calling factual impossibility a valid defense | Eliminate it. Factual impossibility is no defense to attempt; only true legal impossibility is. A choice that flips them is a trap. |
| a 4th Amendment choice ignores standing or a reasonable expectation of privacy and addresses only whether the search was reasonable | Downgrade it. If the defendant lacks standing the search question never reaches the merits; a choice that skips the threshold is incomplete. |
| a choice characterizes the offense as larceny when the defendant lawfully acquired possession first, or as embezzlement when the taking was trespassory from the start | Eliminate it. The line turns on when intent and possession aligned; a mislabeled property crime is a planted distractor. |
| a choice states the correct outcome but pairs it with the wrong rationale, or invokes common-law rules where the question signals the modern/MPC or a controlling statute | Eliminate it. On the MBE the reasoning must be right too; a right-result/wrong-reason answer and a choice citing the superseded rule both lose. |
| The trap | The fix |
|---|
| Confusing larceny and embezzlement by the time intent formed | Ask when the intent to steal arose. Intent at the moment of a trespassory taking is larceny; intent forming after lawful possession is embezzlement. Date the intent before you pick the label. |
| Misapplying transferred intent across crime types | Transferred intent moves the same mens rea from intended victim to actual victim within the same harm (person-to-person homicide/battery). It does not transfer between offense categories (intent to hit a person does not supply intent to damage property). |
| Letting voluntary intoxication excuse a general-intent or malice crime | Voluntary intoxication negates only specific intent. For general-intent, malice, and strict-liability crimes it is no defense, so reject choices that use it to wipe out liability there. |
| Treating any withdrawal as a defense regardless of timing | Check the clock. For conspiracy, withdrawal must come before the overt act to bar the conspiracy itself, and effective renunciation requires affirmative steps; once the substantive crime is complete, withdrawal is too late. |
| Reading felony murder too narrowly by requiring intent to kill | Felony murder needs only intent to commit the underlying inherently dangerous felony plus a death proximately caused during it. Do not graft on an intent-to-kill or general foreseeability requirement. |
| Forgetting the state-action requirement in Procedure | A private search or seizure raises no 4th, 5th, or 6th Amendment claim. Confirm a government actor (or one acting at the government's direction) before applying any constitutional rule. |
| Assuming a Miranda violation taints everything that follows | Separate the warnings issue from the voluntariness and 4th Amendment issues. Un-Mirandized but voluntary statements can still impeach, and physical fruits are usually admissible; reserve full suppression for involuntary statements or genuine 4th Amendment violations. |
| Misjudging consent and standing under the 4th Amendment | Consent must come from someone with actual or apparent authority over the area, and only a person with a personal privacy interest can object. A co-occupant present and refusing blocks consent as to himself; a guest's standing depends on his connection to the place. |
| Collapsing the two causation prongs into one | Always test but-for cause and proximate cause separately. An independent, unforeseeable intervening act (a superseding cause) breaks the chain even when the defendant was a but-for cause. |
| Mixing up insanity tests or treating insanity like diminished capacity | Apply the test the question names — M'Naghten (right/wrong cognition), irresistible impulse, MPC/ALI (appreciate criminality or conform conduct), or Durham. Do not import elements from a different test or treat a mere mental-state argument as a complete insanity defense. |
| If you see / the call says | Then |
|---|
| a choice says evidence is inadmissible because it is hearsay when a clear exclusion or exception plainly applies | Eliminate it. If the statement is a party-opponent admission, excited utterance, business record, or other listed category, the bare hearsay label is wrong. |
| a choice treats the evidence as admissible because it is relevant, full stop | Eliminate it. Relevance is necessary but never sufficient; the item must also survive hearsay, character, privilege, and Rule 403 screening. |
| a choice cites a common-law rule (e.g., the old voucher rule, a defunct competency bar) where the FRE controls | Eliminate it. On the MBE the Federal Rules govern, so an answer resting on superseded common-law doctrine is out. |
| a choice uses an absolute like always inadmissible, never, or automatically excluded | Treat it as presumptively wrong. Nearly every evidentiary bar has exceptions; categorical phrasing rarely survives. |
| a choice gives a reason introduced by because that is true but legally inert | Eliminate it. A correct outcome supported by an irrelevant rationale still fails; the stated reason must be the operative one. |
| a choice labels a statement hearsay when it is offered for a non-truth purpose (notice, effect on listener, verbal act, words of independent legal significance) | Eliminate it. If truth is not the point, the hearsay rule never engages. |
| a choice admits prior bad acts to show propensity (that the person acted in conformity with bad character) | Eliminate it. Propensity use is barred; the act comes in only for a non-propensity MIMIC purpose (motive, intent, mistake, identity, common plan). |
| a choice treats a prior inconsistent statement used to impeach as substantive evidence (or vice versa) without checking it was made under oath at a prior proceeding | Eliminate it. Plain impeachment statements come in only to attack credibility; substantive use requires the 801(d)(1) under-oath foundation. |
| a choice excludes a subsequent remedial measure, settlement, or plea offered for a permitted purpose (ownership/control, impeachment, feasibility when disputed) | Eliminate it. These policy bars exclude the evidence only for the forbidden purpose, not for every purpose. |
| a choice misstates a standard — e.g., requiring the declarant to be unavailable for an 803 exception, or demanding personal knowledge where an admission does not | Eliminate it. A choice that adds or drops a foundational element of the exception is misstating the rule. |
| The trap | The fix |
|---|
| Calling a party-opponent statement hearsay | Remember it is a non-hearsay exclusion under Rule 801(d)(2), not an exception. Any statement of a party offered against that party qualifies, and it needs no against-interest or personal-knowledge showing. |
| Admitting prior bad acts for propensity instead of a MIMIC purpose | Other-acts evidence is barred to show the person is the kind who would do it, but admissible for motive, intent, absence of mistake, identity, or common plan. Confirm a non-propensity purpose and a Rule 403 pass. |
| Blurring impeachment use with substantive use | Ask why the statement is offered. Impeachment attacks credibility only; substantive use proves the matter asserted and needs its own hearsay basis (e.g., a prior inconsistent statement under oath, or an admission). |
| Misordering the availability requirement | Rule 803 exceptions apply whether or not the declarant is available; Rule 804 exceptions (former testimony, dying declaration, statement against interest, forfeiture) require unavailability. Match the exception to the right column before deciding. |
| Confusing the two spousal privileges | Spousal testimonial privilege bars adverse testimony, is held by the witness-spouse, and exists only during marriage; the confidential-communications privilege protects private marital communications, is held by both, and survives divorce. Pick by what is being protected. |
| Letting relevance end the analysis | After confirming relevance, still run hearsay, character, privilege, and Rule 403. Many distractors are seductively relevant yet excluded on a later ground. |
| Overlooking a non-truth purpose that defeats the hearsay objection | Before excluding, ask if the statement matters merely because it was said — to show notice, motive, the listener's state of mind, or as an operative legal act. If so, it is not hearsay at all. |
| Forgetting that policy bars are purpose-specific | Subsequent remedial measures, settlement offers, and pleas are excluded only when offered to prove fault or liability; they are admissible for impeachment, to show ownership/control, or to rebut a feasibility claim. Identify the offered purpose first. |
| Skipping authentication and the best-evidence rule for exhibits | A document needs a sufficient showing that it is what the proponent claims, and proving the contents of a writing generally requires the original or an admissible duplicate. A choice that admits an unauthenticated or non-original writing without explanation is suspect. |
| Treating an opinion objection as automatic | Lay opinion is allowed when rationally based on perception and helpful; expert opinion is allowed on reliable principles applied to the facts. Reject choices that exclude all opinion or that admit an unqualified expert without the reliability foundation. |
| If you see / the call says | Then |
|---|
| A choice says X wins because of a fact that is true but does not affect title, possession, or priority | Eliminate it; a true-but-irrelevant reason cannot support the result even when the conclusion happens to be right. |
| A choice is phrased as if/unless and hinges on a fact the question never gave you | Reject it unless that fact is the sole path to the outcome; an if/unless answer fails when the conditioning fact is absent or non-dispositive. |
| A choice uses absolutes like always, never, cannot, or automatically | Treat it as presumptively wrong; property is riddled with exceptions (notice, estoppel, part performance), so categorical language rarely survives. |
| A choice resolves a recording dispute without ever testing BFP or notice status | Eliminate it; you cannot decide priority under a notice or race-notice act without confirming the later taker is a BFP without notice. |
| A choice treats a fee simple determinable as if entry or court action were required to end it | Eliminate it; a determinable estate ends automatically by possibility of reverter, unlike a fee simple subject to condition subsequent which needs the grantor to exercise a right of entry. |
| A choice misstates the standard, e.g. calls a covenant binding without checking horizontal and vertical privity, intent, touch-and-concern, and notice | Eliminate it; a choice that skips a required element of the running test is stating the wrong rule even if it sounds plausible. |
| A choice decides ownership but ignores who bears the burden of proof or recording (e.g. assumes the unrecorded deed is enforceable against everyone) | Eliminate it; the burden-shifting matters because an unrecorded interest still binds those with notice but may fall to a protected BFP. |
| A choice gives a life tenant a power they lack, like committing waste or conveying a fee | Eliminate it; a life tenant cannot pass more than they hold and is liable for affirmative, permissive, or ameliorative waste. |
| A choice applies a recording act to a party who is a donee, heir, or devisee | Eliminate it; recording acts protect only those who gave value, so a gratuitous transferee is unprotected regardless of recording. |
| A choice validates an interest that violates the Rule Against Perpetuities without checking a measuring life plus 21 years | Eliminate it; if no validating life guarantees vesting in time the contingent interest is void from the start. |
| The trap | The fix |
|---|
| Confusing race, notice, and race-notice acts and applying the wrong one | Read the statute language: under a race act first to record wins regardless of notice; under notice the last BFP without notice wins even if they never record; under race-notice the BFP must take without notice AND record first. |
| Forgetting equitable conversion when a contract is signed but the building burns before closing | Under equitable conversion risk of loss shifts to the buyer at signing in most jurisdictions, so the buyer still must pay even though the seller held legal title at the fire. |
| Assuming a mortgage by one joint tenant severs the joint tenancy everywhere | It depends on theory: in a lien-theory state the mortgage is just a lien and does NOT sever; in a title-theory state the mortgage transfers title and severs that tenant's share into a tenancy in common. |
| Treating a possibility of reverter and a right of entry as interchangeable | A possibility of reverter follows a determinable fee and revests automatically; a right of entry follows a condition subsequent and lies dormant until the grantor affirmatively asserts it. |
| Letting a contingent remainder be destroyed by old common-law rules the question abolished | Check whether the jurisdiction follows the modern view; the destructibility of contingent remainders and the Rule in Shelley's Case are abolished in most states, so the remainder survives as a springing or shifting interest. |
| Granting adverse possession without all elements running for the full period | Demand open, notorious, actual, exclusive, hostile, and continuous possession for the statutory term; permissive use or a gap in continuity defeats the claim, and tacking needs privity. |
| Reading an ambiguous co-tenancy as a joint tenancy | Modern law presumes a tenancy in common unless the four unities plus clear survivorship language appear; without express survivorship words, default to tenancy in common. |
| Allowing an easement to bind a buyer who had no notice | An easement only burdens a later BFP if they had actual, record, or inquiry (visible-use) notice; an unrecorded, non-apparent easement can be cut off by a protected purchaser. |
| Applying the implied warranty of habitability to a commercial lease or to a sale by a non-builder | The implied warranty of habitability protects residential tenants and buyers from builder-vendors of new homes; it does not reach commercial space or casual seller resales. |
| Ignoring the doctrine of merger when a deed is delivered | At closing the contract terms merge into the deed, so a buyer generally cannot sue on a contract promise after accepting the deed unless it is a collateral promise or fraud applies. |
| If you see / the call says | Then |
|---|
| A choice says no liability because another cause also contributed to the harm | Eliminate it; under substantial factor analysis and joint & several liability a defendant whose conduct was a substantial cause is liable even though other forces contributed. |
| A choice answers because of a fact that is true but does not touch any element of the tort | Eliminate it; a true-but-irrelevant reason cannot justify the result, so check that the stated reason actually proves duty, breach, causation, or a defense. |
| A choice is framed as if/unless and turns on a fact not in the stem | Reject it unless that fact is the only route to the outcome; conditional answers fail when the condition is unsupported or non-dispositive. |
| A choice uses absolutes like always liable, never liable, or per se | Treat it as likely wrong; tort liability is fact-sensitive and almost always admits a defense or exception. |
| A choice misstates the standard of care, e.g. holds a defendant to strict liability for ordinary negligence or vice versa | Eliminate it; confirm the right standard, reasonable-person, professional, or strict, before accepting any conclusion built on it. |
| A choice applies a child standard to a child engaged in an adult or inherently dangerous activity | Eliminate it; a minor doing an adult activity (driving, operating machinery) is held to the adult reasonable-person standard. |
| A choice treats negligence per se as automatic without checking that plaintiff is in the protected class and the harm is the type the statute guards against | Eliminate it; statutory violation only sets the standard when both the class-of-person and type-of-harm tests are met, and even then licensing-type statutes may not count. |
| A choice imposes a duty on a defendant who owed none, e.g. a duty to rescue a stranger with no special relationship | Eliminate it; absent a special relationship, creation of the peril, or assumption of duty, there is generally no affirmative duty to act. |
| A choice denies a products claim because the plaintiff was not the buyer | Eliminate it; strict products liability reaches foreseeable users and bystanders, so lack of privity is not a bar. |
| A choice resolves damages without addressing the plaintiff's own fault under the applicable comparative scheme | Eliminate it; you must apply the jurisdiction's comparative rule (pure or modified) or contributory bar before fixing recovery. |
| The trap | The fix |
|---|
| Mixing up contributory and comparative outcomes | Under traditional contributory negligence any plaintiff fault is a total bar (softened only by last clear chance); under pure comparative the plaintiff recovers reduced damages no matter how at fault; under modified comparative recovery is barred once the plaintiff crosses 50 or 51 percent. |
| Reducing damages because the plaintiff was unusually fragile | The eggshell plaintiff rule means you take the victim as you find them; the defendant is liable for the full extent of harm even if a normal person would have been hurt far less. |
| Treating every later event as breaking the causal chain | Distinguish intervening from superseding: a foreseeable intervening cause (ordinary negligent rescue, medical malpractice, normal reactions) leaves liability intact; only an unforeseeable, independent superseding cause cuts it off. |
| Applying one flat duty to every entrant on land | Under the traditional approach the landowner duty varies by class: trespassers get only no-willful-harm (plus the limited duty for known trespassers and the attractive nuisance rule for child trespassers); licensees get warning of known hidden dangers; invitees get reasonable inspection and repair. |
| Confusing assumption of risk with comparative fault | Express assumption of risk (a valid waiver) bars the claim outright, while implied assumption of risk is often merged into comparative fault and only reduces recovery. |
| Granting transferred intent where it does not apply | Transferred intent moves only among the five trespassory torts (battery, assault, false imprisonment, trespass to land, trespass to chattels); it does not stretch to IIED or to negligence. |
| Calling an activity strict liability when it is merely dangerous | Abnormally dangerous activity strict liability requires a foreseeable, highly significant risk that cannot be eliminated with reasonable care and is not common in the community; ordinary risky conduct is judged in negligence. |
| Skipping the type-of-harm filter in strict liability for animals or activities | Strict liability extends only to the kind of harm that makes the activity dangerous; an injury outside that foreseeable risk (e.g. tripping over a sleeping wild animal cage) drops back to negligence. |
| Forgetting that a defense to negligence may not defeat an intentional tort | Match the defense to the tort: consent, self-defense, defense of others, and privilege answer intentional torts, while contributory or comparative fault answers negligence; do not import one set into the other. |
| Letting a private nuisance claim succeed on trivial or hypersensitive interference | Private nuisance requires a substantial and unreasonable interference with use and enjoyment judged by a normal person; a plaintiff's special sensitivity or a minor annoyance is not enough. |
