Agreement point
52 flashcards covering Agreement point for the LSAT Logical Reasoning section.
An agreement point in logical reasoning is a statement or idea that multiple parties or arguments share as true, even if they disagree on other aspects. It's essentially the common ground in a debate, where differing perspectives overlap. Understanding agreement points helps you analyze arguments more effectively, as they reveal underlying assumptions and can strengthen or weaken overall conclusions.
On the LSAT, agreement points frequently appear in Logical Reasoning questions, such as those asking you to identify what two speakers or passages have in common, often in parallel reasoning or flaw-finding tasks. Common traps include confusing superficial similarities with actual agreements or overlooking context that changes meaning. Focus on comparing the core elements of arguments, like premises and conclusions, to spot genuine overlaps accurately.
Always underline shared phrases when practicing these questions.
Terms (52)
- 01
Main Conclusion
The primary claim or point that the argument is trying to establish, often what the premises support and what the author wants the reader to accept.
- 02
Supporting Premise
A statement that provides evidence or reasons to back up the main conclusion in an argument, helping to make the case more persuasive.
- 03
Assumption
An unstated belief or idea that the argument relies on for its conclusion to be valid, which may or may not be true and can be a point of potential weakness.
- 04
Necessary Assumption
A type of assumption without which the argument's conclusion could not logically follow from its premises, making it essential for the argument to hold.
- 05
Sufficient Assumption
A type of assumption that, if true, would fully guarantee the argument's conclusion based on the given premises.
- 06
Strengthen the Argument
A strategy to identify information that would make the argument's conclusion more likely to be true by supporting its assumptions or premises.
- 07
Weaken the Argument
A method to find evidence or reasoning that undermines the argument's conclusion by challenging its assumptions, premises, or logic.
- 08
Flaw in Reasoning
An error in the logical structure of an argument that makes it invalid or unconvincing, such as overlooking alternatives or making unwarranted leaps.
- 09
Circular Reasoning
A flaw where the conclusion is essentially restated in the premises, creating a loop that fails to provide real support for the claim.
- 10
Ad Hominem
A fallacy that attacks the person making the argument rather than addressing the argument's content, diverting attention from the actual issue.
- 11
Appeal to Authority
A flaw that relies on the opinion of an expert or authority figure without sufficient evidence, assuming their view is always correct.
- 12
False Dichotomy
An error that presents only two options as if they are the only possibilities, ignoring other alternatives and oversimplifying the situation.
- 13
Hasty Generalization
A flaw where a conclusion is drawn from a sample that is too small or unrepresentative, leading to an overly broad claim.
- 14
Weak Analogy
A flaw in an argument that compares two things that are not sufficiently similar, making the comparison unreliable for drawing conclusions.
- 15
Causation vs. Correlation
A common trap where an argument mistakenly assumes that because two events are correlated, one must cause the other, without proving a causal link.
- 16
Sampling Error
An issue in arguments based on data where the sample is not representative of the whole population, leading to inaccurate generalizations.
- 17
Parallel Reasoning
A question type that requires identifying an argument with a similar structure or pattern of reasoning to the one in the stimulus.
- 18
Contradictory Premises
A situation in an argument where the given statements conflict with each other, making the conclusion unreliable or impossible.
- 19
Role of a Statement
The function a particular sentence plays in an argument, such as serving as a premise, conclusion, or counterexample.
- 20
Method of Reasoning
The specific way an argument is constructed, such as using analogy, generalization, or counterevidence, which can be analyzed for validity.
- 21
Evaluate the Argument
A question that asks for information needed to assess the strength or weakness of an argument, often by testing key assumptions.
- 22
Resolve the Paradox
A task to explain an apparent contradiction or discrepancy in the stimulus by finding a reconciling fact or principle.
- 23
Point at Issue
The specific disagreement between two speakers or arguments, often requiring identification of what they differ on.
- 24
Must Be True
A question type where the correct answer is something that logically follows directly from the information provided in the stimulus.
- 25
Most Strongly Supported
A variation of inference questions where the answer is the statement best backed by the stimulus, though not necessarily proven.
- 26
Cannot Be True
A question that requires selecting a statement that contradicts or is incompatible with the information in the stimulus.
- 27
Principle
A general rule or guideline that can be applied to specific situations, often used in arguments to justify conclusions.
- 28
Application of Principle
The process of using a broad principle to evaluate or resolve a particular case or argument presented in the stimulus.
- 29
Counterexample
An example that disproves a general claim or principle by showing a case where it does not hold true.
- 30
Conditional Reasoning
Logic involving if-then statements, where the consequent follows only if the antecedent is true, and understanding implications is key.
- 31
Sufficient Condition
The part of a conditional statement that, if met, guarantees the other part will occur, as in 'If A, then B' where A is sufficient for B.
- 32
Necessary Condition
The part of a conditional statement that must be true for the other part to occur, as in 'If A, then B' where B is necessary for A.
- 33
Contrapositive
The logically equivalent reversal of a conditional statement, such as changing 'If A, then B' to 'If not B, then not A'.
- 34
Validity of an Argument
Whether the conclusion logically follows from the premises, regardless of whether the premises are actually true.
- 35
Soundness
The quality of an argument that is both valid and has true premises, making its conclusion reliably true.
- 36
Formal Fallacy
An error in the structure of an argument that violates basic rules of logic, making it invalid regardless of content.
- 37
Informal Fallacy
A flaw in reasoning based on content or context, such as emotional appeals, rather than the argument's logical form.
- 38
Begging the Question
A fallacy where the conclusion is assumed in the premises, essentially arguing in a circle without providing evidence.
- 39
Slippery Slope
A flaw that assumes a small initial step will lead to a series of extreme consequences without evidence to support that chain.
- 40
Post Hoc Ergo Propter Hoc
A fallacy that assumes one event caused another simply because it occurred first, without proving a causal relationship.
- 41
Red Herring
A tactic that introduces an irrelevant issue to distract from the main point of the argument.
- 42
Bandwagon Fallacy
An error that claims something is true or good simply because it is popular or widely accepted, without substantive evidence.
- 43
False Cause
A flaw that incorrectly identifies a cause-and-effect relationship, often confusing correlation with causation.
- 44
Argument by Analogy
A method of reasoning that draws conclusions by comparing two similar situations, which can be strong or weak depending on the parallels.
- 45
Generalization
The process of drawing a broad conclusion from specific instances, which may be flawed if the instances are not representative.
- 46
Exception to the Rule
A case that contradicts a general rule, potentially weakening an argument that relies on that rule.
- 47

An opposing view or evidence that challenges the main argument, often used to test its strength.
- 48
Rebuttal
A response that directly addresses and refutes a counterargument, strengthening the original position.

Something that is suggested or hinted at by the argument without being explicitly stated, requiring careful reading.
- 51
Subsidiary Conclusion
A smaller conclusion that supports the main conclusion, acting as a bridge in the argument's structure.
- 52
Evidence
The facts, data, or examples provided in an argument to support the premises and ultimately the conclusion.
