What is the purpose of using expert opinion in an evidence-based essay?

BlackTom AI · Accepted Answer

Expert opinion provides specialized authority and credibility, so using it in an evidence-based essay strengthens the writer’s claims.

1. Relevant knowledge points and concepts
- Evidence-based writing relies on credible evidence types: facts, statistics, research findings, and expert testimony.
- Ethos (writer credibility) and logos (logical support) are rhetorical appeals; expert opinion primarily boosts ethos and reinforces logos by providing authoritative backing.
- Criteria for good expert evidence: relevant expertise, impartiality, recent and corroborated sources.

2. Step-by-step reasoning
- A claim in an essay is a proposition that needs support.
- Expert opinion supplies informed judgment from someone with demonstrated knowledge or experience in the field.
- Readers are more likely to accept a claim when it is backed by authorities recognized in the topic area.
- Therefore, including expert opinion increases the perceived reliability and persuasiveness of the argument.

3. Calculations/intermediate steps
(Not applicable; this is conceptual reasoning rather than numeric computation.)

4. Why the correct answer is correct
- “It adds credibility and reliability to a writer's argument” captures the primary rhetorical function of expert opinion: to lend authoritative support that makes an argument more convincing. Experts act as trusted sources whose analyses or conclusions validate the essay’s claims.

5. Why the other options are incorrect
- “It promotes recognition for local specialists on an issue.” While citing local specialists may bring recognition, that is not the purpose of using expert opinion; the goal is to support claims, not to promote individuals.
- “It helps a writer specialize in issues from any field.” Expert opinion does not make the writer a specialist; it supplements the writer’s argument with specialist knowledge.
- “It refutes testimony from an opponent's point of view.” Expert opinion can be used to counter opponents, but its primary purpose is to support and add authority to one’s own claims, not solely to refute others.

6. Conclusion
Therefore the correct answer is: It adds credibility and reliability to a writer's argument.
