Assumptions and Underlying Premises Flashcards

An author argues that all art should provoke discomfort in viewers because discomfort leads to growth. Which of the following, if assumed false, most severely damages this argument?

Answer: Discomfort reliably produces meaningful personal or intellectual growth in viewers

If discomfort does not reliably produce growth, the key causal premise collapses and the argument's conclusion loses its only logical support.

Which question best helps identify a hidden assumption in an argument?

Answer: What must be true for the evidence to logically support the conclusion?

Identifying assumptions requires asking what unstated premise must be accepted for the argument's logic to hold, revealing the hidden gap between stated evidence and the drawn conclusion.

A scientist writes that a new drug is safe for human use because it produced no adverse effects in mice. Which assumption most critically supports this conclusion?

Answer: Physiological responses observed in mice are sufficiently predictive of responses in humans

The argument requires assuming the mouse model is a valid proxy for human biology—without this, mouse results cannot license conclusions about human safety.

An author distinguishes between assumptions an argument needs and assumptions an argument makes but does not need. Why is this distinction important in CARS?

Answer: Only necessary assumptions, when negated, destroy the argument; unnecessary assumptions merely adjust its strength

Necessary assumptions are logical requirements whose negation dismantles the argument, while unnecessary ones are supplementary and their negation leaves the core reasoning intact.

A humanities scholar argues that understanding historical context is essential for correctly interpreting literature. What definitional assumption underlies this view?

Answer: 'Correct interpretation' means alignment with the author's intended meaning, which is shaped by historical context

The scholar implicitly defines correct interpretation as historically grounded authorial intent, which is a definitional assumption about what 'correct' means in literary analysis.

When an author presents multiple individually weak premises to build a conclusion, a hidden assumption is often that:

Answer: The cumulative weight of several moderate considerations together justifies the conclusion even when no single premise does so alone

Cumulative arguments assume that converging weak evidence combines into a persuasive case—a holistic view of argumentative support rather than a premise-by-premise standard.

A passage claims that people who read fiction develop greater empathy, then recommends fiction as a tool for conflict resolution. What assumption enables this policy recommendation?

Answer: Greater empathy as developed through fiction would meaningfully contribute to resolving interpersonal or social conflicts

The recommendation requires assuming that empathy developed through fiction translates into the practical understanding needed to resolve real-world conflicts.
