LSAT (Law School Admission Test) flashcards

An unstated belief or premise about the environmental consequences of an action, which is necessary for the argument's conclusion regarding environmental benefit or harm to hold true.

• Often involves assumptions about the 'greenness' of alternatives.
• Challenges involve exposing hidden costs or externalities.
• Argument fails if the implicit assumption is false.

Memory trick: Green claims need unseen screens!

Occurs when an arguer attributes an effect to one cause without adequately considering other plausible causes that could explain the effect.

• Confuses correlation with causation.
• Ignores other variables that might be at play.
• Undermines the certainty of the proposed causal link.

Memory trick: Causation isn't just correlation; look for other routes.

The main point of an argument is the central conclusion that the author is trying to persuade the audience to accept.

• It's the claim that all other statements in the argument are intended to support.
• Often signaled by conclusion indicators like 'therefore,' 'thus,' 'consequently,' or 'it follows that.'
• Can sometimes be implied, requiring careful synthesis of the premises.

Memory trick: Think 'CAP': Conclusion, Assumption, Premise.

A flaw in reasoning where an argument assumes that a given condition or action is sufficient to guarantee a particular outcome, without considering other factors that might prevent that outcome from occurring.

• Confuses a necessary condition with a sufficient condition.
• Often overlooks 'other things being equal' assumptions.
• Weakens arguments by showing the proposed solution might not be enough.

Memory trick: Just because you *can* do it, doesn't mean it *will* happen.

A necessary assumption in a causal argument is an unstated premise that must be true for the stated cause-and-effect relationship to hold, often by ruling out alternative causes or ensuring the cause precedes the effect.

• The argument claims one event (the cause) directly leads to another (the effect).
• A necessary assumption often eliminates alternative causes for the effect.
• It can also ensure there are no other factors preventing the cause from producing the effect.
• To test, negate the assumption: if the argument's conclusion becomes impossible or illogical, it's necessary.

Memory trick: Causal arguments need 'NO GAP': No other cause, Only that cause, Precedes, Absence of interfering factors.

A flaw in reasoning where an argument draws conclusions about change or effectiveness by comparing current data to a baseline that is either unstated, inappropriate, or itself subject to fluctuations that render the comparison misleading.

• Often involves comparing 'before' and 'after' without proper context.
• Assumes the baseline is stable or typical.
• Weakens arguments by making observed changes seem more significant than they are.

Memory trick: Always check if the starting line is fair before judging the race.

An unstated premise that links the steps in a causal chain, ensuring that each cause-and-effect relationship in the sequence is valid for the overall conclusion to hold.

• Connects intermediate steps in a causal argument
• Must be true for the chain to remain unbroken
• Often relates to the sufficiency of a cause

Memory trick: Every link in the chain must hold!

A logical fallacy where a conclusion is drawn about an entire group or category based on insufficient or unrepresentative evidence, or where a specific finding is applied too broadly.

• Often uses words like 'all,' 'every,' 'always,' 'never,' or 'ineffective' (broadly).
• Challenges involve pointing out exceptions or specific contexts where the generalization doesn't hold.
• Can stem from small sample sizes or biased observations.

Memory trick: Small sample, big leap? That's a logical creep!

A flaw where an argument reduces a complex issue to an overly simple choice or a limited set of options, ignoring other possibilities or nuances.

• Presents a complex problem as having only one or two solutions/outcomes.
• Ignores alternative factors, responses, or mediating variables.
• Often uses absolute language ('inevitably,' 'only').

Memory trick: Complex problems have many paths; don't simplify them to just one wrath!

A flaw where an argument attributes an effect to a single cause, ignoring other potential contributing factors or alternative explanations for the observed outcome.

• Assumes one cause is the only cause
• Ignores confounding variables
• Weakens a causal conclusion

Memory trick: Don't assume one thing is the ONLY thing!

An unwarranted conclusion is one that does not logically follow from the evidence or premises provided, often due to faulty reasoning, overlooked factors, or a misinterpretation of data.

• The conclusion is stronger than the premises support.
• Often ignores alternative explanations.
• May involve a logical leap.

Memory trick: Does the evidence truly earn the conclusion's embrace?

A flaw in reasoning where an arguer attributes an observed phenomenon to one cause or interpretation, while ignoring other plausible explanations that could account for the same data.

• Challenges the uniqueness of the proposed explanation.
• Often involves identifying a confounding variable or a different underlying process.
• Undermines the certainty of the conclusion drawn from the data.

Memory trick: Don't jump to conclusions; another story fits the facts.

An appeal to consequences is a fallacy where a belief is judged to be true or false based on the desirability of its consequences, rather than on its truth value or internal logic. It asserts that if a belief leads to a good outcome, it must be true, or if it leads to a bad outcome, it must be false.

• Evaluates a claim based on the outcomes of believing or acting on it.
• Does not address the logical validity or truth of the claim itself.
• Often takes the form: 'X causes Y; Y is bad, so X is false/bad.'

Memory trick: Don't judge the idea by the play's ending, but by the script's logic.

A fallacy that presents only two options or outcomes as exhaustive and mutually exclusive, when in reality there are other possibilities or a combination of options is possible.

• Often presented as 'either/or' situations.
• Limits the scope of possibilities unfairly.
• Can be implied rather than explicitly stated.

Memory trick: Don't omit the middle ground; other options can always be found!

Attacking a premise is a method of weakening an argument by demonstrating that one of its foundational statements, upon which the conclusion rests, is false, unsubstantiated, or highly doubtful. If a premise is false, the conclusion derived from it cannot be reliably true.

• Targets the truthfulness of the evidence itself.
• Directly undermines the foundation of the argument.
• Distinguish from attacking the *reasoning* or *conclusion*.

Memory trick: Knock down a foundational brick, and the whole wall trembles.

A flaw in reasoning where a claim about effectiveness or change is made without comparing the observed results to a baseline, control group, or alternative conditions.

• Makes it impossible to determine if the measured effect is due to the intervention.
• Fails to account for placebo effect, natural remission, or other confounding variables.
• Essential for establishing true causality or effectiveness in experiments.

Memory trick: To claim effectiveness, a comparison you must make; without a baseline, your argument will break!

A flaw in reasoning where evidence about a specific part or aspect is used to draw a conclusion about the entire whole, without justification for generalizing.

• Assumes that what is true for a part is true for the whole.
• Fails to consider if other parts might behave differently.
• Often occurs when generalizing from specific examples or sectors.

Memory trick: Don't assume the whole is just the sum of its parts; look for differences in scope and separate starts!

A flaw in reasoning where an argument presents data or observations and draws a specific conclusion, but fails to consider or rule out other plausible interpretations or explanations for that same data.

• The data itself is not disputed, but its meaning is.
• Requires considering multiple ways the evidence could be explained.
• Weakens an argument by showing the conclusion might not be the only possible one.

Memory trick: Don't just see one puzzle piece and assume the whole picture.

An equivocation flaw occurs when a key term or phrase in an argument is used with two or more different meanings, leading to a misleading or invalid conclusion. The argument relies on the shift in meaning to appear sound.

• A single word or phrase is used ambiguously.
• The different meanings are crucial to the argument's validity.
• The argument appears logical only if the different meanings are ignored.

Memory trick: The word wears two masks, and the argument gets lost in the disguise.

A belief or premise that the author takes for granted as true, even though it is not explicitly stated in the passage, and upon which the author's argument depends.

• It must be necessary for the author's argument to hold true.
• It will not be directly stated in the text.
• If the assumption were false, the author's conclusion or reasoning would be weakened or invalid.

Memory trick: Assumptions Are the Unspoken Foundations.

The main reason an author wrote a passage, often encompassing the central idea and the author's approach to it.

• Look for the overall message or goal.
• Consider how the author presents information (e.g., explains, argues, analyzes).

Memory trick: What's the Author's Grand Design?

Pinpointing the specific ways in which two or more concepts, arguments, or phenomena presented in a passage diverge.

• Look for explicit comparisons or contrasts using words like 'unlike,' 'whereas,' 'in contrast to.'
• Focus on the core characteristics or mechanisms that distinguish them.
• Avoid superficial differences or details not emphasized by the author.

Memory trick: Find the Gap, The Key Disparity.

Understanding figurative language (like metaphors, idioms, or evocative phrases) requires inferring the author's intended meaning beyond the literal words.

• Look at the surrounding context.
• Consider the author's overall tone and argument.
• Identify the implied comparison or effect.

Identifying a situation or relationship that is similar in structure or principle to one described in the passage, even if the specific content differs.

• Requires understanding the core principle of the concept in the passage.
• Looks for structural similarities, not literal matches.
• Often involves abstracting the relationship between elements.

Memory trick: Find the parallel link, the 'analog' match.

To find the LEAST analogous scenario, identify the option that shares the fewest core characteristics or underlying principles with the situation described in the passage.

• Identify the core principle/tension in the passage.
• Evaluate each option for similarities to this core principle.
• The 'least analogous' will be the one that deviates most significantly.

Memory trick: The 'Least Analogous' is the 'Puzzle Piece that Doesn't Fit' the core pattern.

An immediate and explicit result or outcome that directly follows from a stated condition or phenomenon in the text.

• Requires identifying a clear cause-and-effect relationship.
• The consequence must be explicitly stated or a very close paraphrase.
• Distinguish from implications or inferences that require more reasoning.

Memory trick: The cause leads directly to the effect, like a domino fall.

• Look for phrases like 'for instance,' 'another example,' or 'such as.'
• Connect the specific detail back to the main idea or the paragraph's topic sentence.
• Consider what general point the author is trying to make by providing this particular piece of information.

Memory trick: Examples Illuminate the Main Point Clearly.

Examples are used in a passage to clarify or illustrate abstract concepts, theories, or general statements.

Memory trick: Not That, But This: Clarify the Line.

A stated reason or cause is an explicit explanation provided in the text for why something occurs or why a particular claim is true.

• Directly mentioned in the passage.
• Answers 'why' or 'how' an event happens.
• Requires careful reading of cause-and-effect language.

Memory trick: Explicit causation is the 'Direct Arrow' from cause to effect.

The illustrative function of a detail refers to how it serves to clarify, exemplify, or emphasize a point being made by the author.

• Serves to explain or clarify.
• Emphasizes a particular characteristic.
• Provides a concrete example of an abstract idea.

• Connects a concept's definition to its observed manifestation.
• Goes beyond surface-level description to deeper implications.
• Often involves identifying the 'mechanism' by which something occurs.

• Inferred from word choice and phrasing.
• Distinguish from explicit statements.
• Can be neutral, positive, negative, or mixed.

Memory trick: Tone is the 'Emotional Echo' in the author's words.

Identifying common themes, topics, or aspects that are discussed in two or more related passages.

• Requires reading both passages for overarching connections.
• Focuses on what they both address, not necessarily how they differ.
• Often involves synthesizing main ideas from each text.

Memory trick: Two paths meet at a common puzzle piece.

To challenge an assertion is to find information that directly contradicts or undermines the truth or validity of a specific claim made in the passage.

• Requires identifying the specific claim.
• Looks for information that weakens or refutes the claim.
• Must directly relate to the assertion, not tangential issues.

Memory trick: To challenge a claim, find the 'Sword of Contradiction' that cuts its truth.

To identify agreement between different viewpoints, find a statement or underlying assumption that both sides implicitly or explicitly share.

• Look for common ground in stated positions.
• Infer shared assumptions or frameworks.
• Distinguish common ground from specific arguments.

Memory trick: Agreement is the 'Shared Target' both sides aim at, even with different arrows.

A question that requires identifying the underlying reason or cause for a phenomenon or statement explicitly mentioned in the text.

• Focuses on 'why' something is the way it is.
• Requires connecting a stated fact to its stated explanation.

• Requires applying the passage's concept to a new example.
• Tests understanding of the concept's practical manifestation.
• Look for the core mechanism or definition to be present in the scenario.

Memory trick: Apply the mind's concept to the real world.

Drawing a conclusion based on a hypothetical condition ('If X is true, then what must follow according to the passage?').

• Requires careful reading of conditional statements or implications.
• Tests understanding of cause-and-effect or logical relationships.
• Often involves applying a passage's rule to a new scenario.

Memory trick: What future unfolds if this condition comes true?

A conclusion reached on the basis of evidence and reasoning, rather than explicit statements in the text.

• Requires connecting information within the passage.
• Must be supported, not merely consistent, with the text.
• Goes beyond what is stated but does not introduce outside information.

Memory trick: Connect the puzzle pieces to see the hidden light.

Identifying which part of a theory or hypothesis would be disproven or severely undermined by a specific piece of evidence or scenario.

• Understand the specific claims of each part of the hypothesis.
• Match the evidence in the scenario to the information type addressed by each claim.
• A hypothesis is challenged when its specific prediction is contradicted by observed reality.

Memory trick: Information Type Unravels the Hypothesis.

Understanding why an author introduces opposing views or alternative perspectives in a passage, often to qualify, challenge, or refine a preceding argument.

• Often signaled by transition words like 'however,' 'nevertheless,' 'but,' or phrases like 'some argue.'
• Can be used to show the complexity of an issue, introduce a new angle, or set up a refutation.
• It helps to develop a more nuanced or balanced discussion.

Memory trick: Counterpoints Challenge, Clarify, and Create Complexity.

Identifying the statement that is most directly and comprehensively substantiated by the information provided in the passage.

• Look for explicit statements or direct logical implications.
• Avoid options that generalize too broadly or introduce new information.
• The best answer will often summarize a key conclusion or principle.

Memory trick: The Passage's True Anchor.

Identifying statements with which the author of the passage would likely concur, based on the arguments, facts, and tone presented.

• Look for direct statements, strong implications, or logical conclusions from the author's arguments.
• Exclude statements that contradict the author's viewpoint or introduce unsupported claims.
• Consider the overall thrust and message of the passage.

Memory trick: What Would the Author Nod 'Yes' To?

Identifying information explicitly stated or directly derivable from the text.

• Focus on keywords and phrases from the question.
• Scan the passage for direct matches or close paraphrases.
• Avoid making inferences beyond what is directly stated.

Memory trick: Spot the Exact Words, Don't Guess Beyond.

The organizational pattern or rhetorical strategy an author uses to present information and ideas in a text.

• Helps understand how ideas are connected.
• Common structures include comparison/contrast, cause/effect, problem/solution, chronological.
• Identified by analyzing the flow of arguments and evidence.

Memory trick: Build the passage map to see its structure.

Rules that determine which elements can or must be selected together, or which cannot be selected together.

• Often uses 'if-then' or 'either-or' structures.
• Involves selecting a subset from a larger group.
• Violation of any condition makes the group invalid.

Memory trick: Choices Are Grouped By Condition's Logic.

Examining all possible valid scenarios or arrangements to determine what properties are shared by all of them.

• Used to find 'must be true' conclusions.
• Requires constructing and validating multiple scenarios.
• If a property appears in all valid scenarios, it 'must be true'.

Memory trick: Every Path Leads To This Single Truth.

A strategy to determine if a specific scenario is valid by attempting to construct an arrangement that satisfies all rules.

• Involves creating a hypothetical setup.
• Systematically checking each rule against the hypothetical setup.
• If one valid setup is found, the scenario is possible.

Memory trick: Build A Valid Example To Prove It's Possible.

Verifying if a given group of selected members adheres to all specified inclusion and exclusion rules.

• Each rule must be checked against the proposed committee.
• Violation of any single rule invalidates the committee.
• Involves conditions based on presence, absence, or co-occurrence of members.

Memory trick: Committee Rules Ensure Correct Members.

Rules that dictate the sequence or relative positions of elements in a set.

• Elements must be arranged in a specific sequence.
• Rules can be absolute (e.g., 'first' or 'last') or relative (e.g., 'before' or 'after').
• Conditional statements are common.

Memory trick: Sequential Steps Ensure Logical Flow.

A conclusion that is logically necessitated by the given rules and a specific premise, regardless of other variable choices.

• Often derived by combining multiple rules.
• Represents an unavoidable outcome.
• Can lead to the elimination of other possibilities.

Memory trick: Premise Sparks Sure Conclusions.

Combining a series of 'if-then' statements to derive a new, often indirect, conclusion.
