Premise vs conclusion
57 flashcards covering Premise vs conclusion for the GMAT Verbal section.
In arguments, a premise is the supporting evidence or reasons that form the foundation of a claim, while the conclusion is the main point or assertion that the premises aim to prove. For example, in a statement like "All mammals have fur, and dogs are mammals, so dogs have fur," the premises are the first two parts, and the conclusion is the final claim. This concept is essential for breaking down logical structures and evaluating their validity, which builds critical thinking skills.
On the GMAT Verbal section, premise and conclusion appear mainly in Critical Reasoning questions, where you might strengthen, weaken, or identify assumptions in arguments. Common traps include mistaking supporting details for the main conclusion or overlooking implicit premises, which can lead to incorrect answers. Focus on spotting indicator words like "therefore" or "thus" for conclusions, and practice analyzing argument flow to handle these questions effectively.
A helpful tip: Always map out the argument's structure before answering.

- 01
Premise
A premise is a statement in an argument that serves as evidence or a reason to support the conclusion, providing the foundational facts or assumptions.
- 02
Conclusion
A conclusion is the main claim or inference in an argument that the premises are intended to support, representing the point the argument is trying to prove.
- 03
Difference between Premise and Conclusion
The key difference is that a premise provides supporting evidence, while a conclusion is the result or claim derived from that evidence in an argument.
- 04
Identifying a Conclusion
To identify a conclusion, look for the main point of the argument, often signaled by words like 'therefore,' 'thus,' or 'hence,' and check if it is what the premises are building toward.
- 05
Identifying a Premise
To identify a premise, find statements that offer reasons or evidence for the conclusion, typically introduced by words like 'because,' 'since,' or 'for example'.
- 06
Conclusion Indicators
Conclusion indicators are words or phrases that signal the presence of a conclusion in an argument, such as 'therefore,' 'consequently,' 'it follows that,' or 'as a result'.
- 07
Premise Indicators
Premise indicators are words or phrases that introduce supporting evidence in an argument, including 'because,' 'since,' 'for,' 'as,' or 'given that'.
- 08
Argument Structure
An argument structure typically consists of one or more premises followed by a conclusion, where the premises logically lead to the conclusion in a coherent flow.
- 09
Role of Premises
Premises play the role of providing the necessary evidence or reasons that make the conclusion plausible or logical within an argument.
- 10
Role of Conclusion
The conclusion serves as the ultimate claim or decision point in an argument, relying on the premises to establish its validity.
- 11
Implicit Premise
An implicit premise is a supporting statement that is not explicitly stated in the argument but is assumed to be true and necessary for the conclusion to hold.
- 12
Explicit Premise
An explicit premise is a supporting statement that is directly stated in the argument, clearly providing evidence for the conclusion.
- 13
Weak Premise
A weak premise is one that lacks sufficient evidence or reliability, potentially undermining the strength of the argument's conclusion.
- 14
Strong Premise
A strong premise is one that is well-supported by facts or logic, effectively bolstering the argument's conclusion.
- 15
Assumption in Premises
An assumption in premises is an unstated belief or condition that must be true for the premises to logically lead to the conclusion.
- 16
Counterpremise
A counterpremise is a statement that challenges or contradicts a premise in an argument, potentially weakening the overall conclusion.
- 17
Premise-Conclusion Relationship
The premise-conclusion relationship is the logical link where premises must provide adequate support for the conclusion to be valid in an argument.
- 18
Flawed Premise
A flawed premise is one that contains errors, biases, or inaccuracies, which can lead to an invalid or misleading conclusion.
- 19
Valid Conclusion
A valid conclusion is one that logically follows from the premises without contradictions, assuming the premises are true.
- 20
Invalid Conclusion
An invalid conclusion is one that does not logically follow from the premises, often due to gaps in reasoning or unsupported claims.
- 21
Simple Argument Example
In a simple argument, premises directly support a single conclusion, such as stating facts that lead to a straightforward inference.
- 22
Complex Argument Example
In a complex argument, multiple premises interact to support a conclusion, often involving layers of reasoning or conditional statements.
- 23
Premises as Facts
Premises as facts are statements based on verifiable evidence, making them reliable supports for a conclusion in an argument.
- 24
Premises as Opinions
Premises as opinions are subjective statements that may not be universally accepted, potentially weakening the argument's conclusion.
- 25
Conclusion as Prediction
A conclusion as prediction is a forward-looking claim based on premises, forecasting an outcome that may or may not occur.
- 26
Strategy for Spotting Conclusions
A strategy for spotting conclusions is to read the argument and identify the statement that the other parts are trying to prove or justify.
- 27
Strategy for Spotting Premises
A strategy for spotting premises is to look for statements that explain or provide reasons for another part of the argument.
- 28
Common Trap: Confusing Premise and Conclusion
A common trap is mistaking a premise for the conclusion or vice versa, which can lead to errors in evaluating the argument's logic.
- 29
Common Trap: Overlooking Premises
Overlooking premises means ignoring key supporting statements, which can result in misunderstanding the argument's foundation.
- 30
Common Trap: Assuming All Statements Are Premises
Assuming all statements are premises can cause one to miss the actual conclusion, distorting the analysis of the argument.
- 31
Worked Example: Basic Argument
In this example, the premise 'All mammals have fur' and 'Dogs are mammals' lead to the conclusion 'Dogs have fur', illustrating a straightforward logical flow.
Premise: All birds have feathers. Premise: Eagles are birds. Conclusion: Eagles have feathers.
- 32
Worked Example: With Indicators
Here, the premise 'Because exercise improves health' leads to the conclusion 'People should exercise regularly', showing how indicators clarify the structure.
- 33
Worked Example: Implicit Premise
In this case, the explicit premise 'Smoking causes lung cancer' implies an unstated premise about health risks to reach the conclusion 'Smoking is harmful'.
- 34
Evaluating Premise Strength
Evaluating premise strength involves assessing whether the supporting statements are based on solid evidence, as weak premises can invalidate a conclusion.
- 35
Circular Reasoning Trap
Circular reasoning is a trap where the conclusion is restated as a premise, creating an illusion of support without actual evidence.
- 36
Premise in Conditional Statements
In conditional statements, a premise often forms the 'if' part, which must be true for the conclusion in the 'then' part to follow.
- 37
Conclusion in Inferences
A conclusion in inferences is the deduced result from premises, requiring careful logic to ensure it accurately reflects the evidence.
- 38
Multiple Premises Example
An example with multiple premises might include two or more supporting statements converging to support a single conclusion, like in complex debates.
- 39
Premise-Conclusion Chain
A premise-conclusion chain is a series where one conclusion becomes a premise for the next, building a layered argument.
- 40
Faulty Analogy in Premises
A faulty analogy in premises occurs when a comparison is used as evidence but doesn't hold up, weakening the conclusion.
- 41
Overgeneralization in Conclusions
Overgeneralization in conclusions happens when premises lead to a broader claim than the evidence supports, creating a logical flaw.
- 42
Hasty Conclusion
A hasty conclusion is one drawn from insufficient premises, lacking the necessary evidence to make it reliable.
- 43
Strengthening via Premises
Strengthening an argument via premises involves adding or identifying stronger supporting evidence to make the conclusion more convincing.
- 44
Weakening via Conclusions
Weakening an argument via conclusions means challenging the logical leap from premises, showing it doesn't necessarily follow.
- 45
Assumption Questions
In assumption questions, identifying hidden premises is key, as they bridge the gap between stated premises and the conclusion.
- 46
Inference Questions
Inference questions require drawing a conclusion based on given premises, ensuring it logically follows without adding new information.
- 47
Counterexample to Premise
A counterexample to a premise is an instance that disproves it, thereby undermining the argument's conclusion.
- 48
Rebuttal of Conclusion
A rebuttal of a conclusion involves presenting evidence or premises that directly contradict the original claim.
- 49
Premise Evaluation in GMAT
In GMAT Critical Reasoning, evaluating premises means checking their truthfulness and relevance to ensure the conclusion is sound.
- 50
Conclusion Evaluation in GMAT
Evaluating a conclusion in GMAT involves verifying if it logically results from the premises without unwarranted jumps.
- 51
Analogical Premises
Analogical premises use comparisons as evidence, where the similarity between cases supports the conclusion if the analogy is apt.
- 52
Causal Premises
