Product Description Research & Evidence-Based Practice 5 — Questions and Answers
Question 1: A copywriter is asked to write a description for a weight-loss product claiming '10 lbs in 10 days.' The best response is to:
- Use the claim as it is — it's the brand's responsibility
- Request the clinical evidence behind the claim before including it (Correct answer)
- Rewrite it as a customer testimonial to reduce legal risk
- Add an asterisk but keep the claim as stated
Correct answer: Request the clinical evidence behind the claim before including it
Copywriters share ethical responsibility for accuracy; requesting substantiating evidence before using extraordinary claims protects both consumers and the brand.
Question 2: What distinguishes a feature from evidence in a product description?
- Features are longer descriptions; evidence is shorter
- Features describe what a product has; evidence proves why it matters or works (Correct answer)
- Features are written by engineers; evidence is written by marketers
- Features are optional; evidence is required by law
Correct answer: Features describe what a product has; evidence proves why it matters or works
A feature (e.g., 'carbon fiber frame') states a product attribute, while evidence (e.g., 'lab-tested to withstand 500 lbs') validates its performance.
Question 3: Which of the following best describes 'social proof' as a research-backed persuasion tool in product descriptions?
- Using social media imagery to make products look trendy
- Leveraging reviews, ratings, and usage numbers to show others trust the product (Correct answer)
- Designing copy that feels informal and conversational
- Referencing social media influencer follower counts
Correct answer: Leveraging reviews, ratings, and usage numbers to show others trust the product
Social proof relies on psychological research showing that people trust products others have already validated through purchases and reviews.
Question 4: A product description for a UV water purifier states it 'eliminates 99.9% of bacteria.' To use this claim responsibly, the copywriter should verify:
- Whether the percentage sounds believable to consumers
- The specific testing standard (e.g., NSF/ANSI 55) and whether the product is certified to it (Correct answer)
- If the claim matches what competitors say about their products
- Whether the claim fits within the allotted character count
Correct answer: The specific testing standard (e.g., NSF/ANSI 55) and whether the product is certified to it
Specific efficacy percentages must be tied to recognized testing standards and certifications to be accurate and legally defensible.
Question 5: Why should a copywriter avoid using outdated research to support a product claim, even if the research previously supported the claim?
- Outdated research looks unprofessional in product descriptions
- Newer studies may have contradicted the finding, making the claim inaccurate (Correct answer)
- Publishers may penalize descriptions citing old research
- Outdated research is automatically classified as anecdotal evidence
Correct answer: Newer studies may have contradicted the finding, making the claim inaccurate
Scientific consensus evolves; using superseded research can result in inaccurate or misleading claims that harm consumers and expose brands to liability.
Question 6: A fitness equipment brand wants to add 'As seen in Men's Health' to their product description. Before using this claim, what must the copywriter confirm?
- That the magazine is still in print
- That the feature was an editorial mention, not a paid advertisement, or that paid placement is clearly disclosed (Correct answer)
- That the product is still the same model featured
- That the magazine's readership matches the brand's target demographic
Correct answer: That the feature was an editorial mention, not a paid advertisement, or that paid placement is clearly disclosed
FTC guidelines require that paid placements be disclosed; passing off an ad as an editorial endorsement is a deceptive practice.
Question 7: What is the purpose of a 'proof stack' in an evidence-based product description?
- A list of product dimensions and materials stacked by importance
- Layering multiple types of evidence (statistics, testimonials, certifications) to build cumulative credibility (Correct answer)
- A sequence of headlines designed to increase scroll depth
- A collection of competitor comparisons organized by price
Correct answer: Layering multiple types of evidence (statistics, testimonials, certifications) to build cumulative credibility
A proof stack combines different evidence types so that even skeptical buyers encounter multiple, reinforcing reasons to trust the product.
