Analysis Flashcards

A researcher states: 'Students who eat breakfast perform better on tests.' Which of the following best identifies the implicit assumption in this claim?

Answer: Breakfast causes improved test performance

The claim assumes a causal relationship, but correlation between breakfast and performance does not itself establish causation.

Which analytical approach best distinguishes between a premise and a conclusion in an argument?

Answer: A premise is a statement offered as support; a conclusion is what the argument tries to establish

Premises are the supporting reasons, while the conclusion is the claim those reasons are meant to justify.

A passage argues: 'No elite athlete lacks discipline, and Maria is an elite athlete.' What follows necessarily?

Answer: Maria has discipline

From 'no elite athlete lacks discipline' and 'Maria is an elite athlete,' it necessarily follows that Maria has discipline.

When analyzing an argument, identifying the 'scope' of a claim primarily helps to:

Answer: Determine whether the claim is too broad or too narrow for its evidence

Analyzing scope reveals whether the evidence actually supports the breadth of the claim being made.

Which of the following is an example of an argument by analogy?

Answer: Just as a chain is only as strong as its weakest link, a team is only as strong as its weakest member

An argument by analogy draws a parallel between two things and infers that what is true of one is true of the other.

A policy states: 'Employees must report all conflicts of interest.' An employee owns stock in a client company. Which analysis is most accurate?

Answer: Owning stock in a client company is a conflict of interest that must be reported

Stock ownership in a client company creates a financial interest that could influence professional judgment, fitting the definition of a conflict of interest.

In analyzing a complex text, which skill is most essential for identifying the author's central thesis?

Answer: Distinguishing main claims from supporting details and examples

The central thesis is the primary claim the author advances; all supporting details and examples serve to develop or support it.

A graph shows that ice cream sales and drowning rates both peak in summer. A commentator concludes that ice cream causes drowning. This error is best described as:

Answer: Confusing correlation with causation

Both variables are driven by a third factor (summer heat), making this a classic case of mistaking correlation for a causal relationship.

Which of the following best describes a 'necessary condition' in logical analysis?

Answer: A condition that must be present for an outcome to occur, though it may not be sufficient alone

A necessary condition must be met for the outcome to occur, but it alone may not bring about that outcome.

An argument states: 'Either we raise taxes or cut services. We cannot cut services. Therefore, we must raise taxes.' This is an example of:

Answer: Disjunctive syllogism

Disjunctive syllogism eliminates one option from an either/or statement to conclude the other must be true.

When a study uses a sample of only college students to draw conclusions about 'all adults,' the primary analytical concern is:

Answer: Whether the sample is representative of the broader population

College students differ systematically from the general adult population, so the sample may not support conclusions about all adults.

Which of the following statements is an analytic (logically true) claim?

Answer: All bachelors are unmarried

'Bachelor' is defined as an unmarried man, so 'all bachelors are unmarried' is true by definition, not by observation.

A critical thinker reading an editorial notices the author only cites evidence that supports the position and ignores contradictory data. This is best identified as:

Answer: Selective use of evidence (cherry-picking)

Cherry-picking involves presenting only favorable evidence while omitting contradictory data, creating a misleadingly one-sided picture.

If the statement 'All reptiles are cold-blooded' is true, which of the following must also be true?

Answer: If an animal is not cold-blooded, it is not a reptile

The contrapositive of 'All A are B' is 'If not B, then not A,' which is logically equivalent and must be true.

An argument contains the phrase 'studies show.' A strong analytical reader should first ask:

Answer: Which studies, conducted how, and with what results?

Vague appeals to 'studies' lack specificity; an analyst must probe the methodology, source, and findings before accepting the claim.

Which of the following best describes 'parsing' an argument for its logical structure?

Answer: Identifying the premises, the conclusion, and the inferential links between them

Parsing an argument means laying bare its logical skeleton: what claims serve as reasons and what claim they are meant to support.

A politician argues: 'My opponent wants to reduce military spending—clearly, she wants to leave our country defenseless.' This is an example of:

Answer: Straw man fallacy

The straw man fallacy misrepresents an opponent's position in an exaggerated or distorted form that is easier to attack.

In a deductive argument, if the premises are true and the argument is valid, the conclusion:

Answer: Must be true

In a valid deductive argument, true premises guarantee a true conclusion—this is the defining feature of deductive validity.

Which technique is most useful for identifying whether two seemingly different arguments actually share the same logical form?

Answer: Substituting variables for content words and comparing the resulting abstract structures

Abstracting content into variables reveals the underlying logical form, making structural comparisons possible regardless of subject matter.

A news article reports that a new drug 'significantly' reduces symptoms. In critical analysis, the most important follow-up question is:

Answer: What does 'significantly' mean—statistically, clinically, or practically?

Statistical significance does not equal practical importance; the term 'significant' is often used ambiguously and must be precisely defined.
