No audio/visual elements may interfere with comprehension of major statement

AI-verifiedwarningBinding lawRaised as a question — a person decides

Rule

During the presentation of the major statement, the ad must not include audio or visual elements, alone or in combination, that are likely to interfere with comprehension of the major statement.

Check

Review the major statement segment for audio or visual elements (e.g., competing music or sound effects, on-screen action, scene changes, superimposed text) and assess whether any element, or several in combination, is likely to impair the viewer's or listener's comprehension of the major statement — not merely whether attention-competing elements are present.

Escalate when

Whether an element or combination of elements is 'likely to interfere with comprehension' (as opposed to merely being present alongside the major statement) requires human judgment about audience perception.

Where this comes from

21 CFR 202.1(e)(1)(ii)(E). The highlighted words are quoted exactly; a script confirms they appear in the source before the rule can be published.

…tion is considered sufficient if the text display begins at the same time and ends at approximately the same time as the corresponding audio. (D) In advertisements in television format, for the text portion of the major statement, the size and style of font, the contrast with the background, and the placement on the screen allow the information to be read easily. (E) During the presentation of the major statement, the advertisement does not include audio or visual elements, alone or in combination, that are likely to interfere with comprehension of the major statement. (2) Exempt advertisements. The following advertisements are exempt from the requirements of paragraph (e)(1) of this section under the conditions specified: (i) Reminder advertisements. Reminder advertisements are those which call attention to the name of the drug product but do not include indications or dosage recommendations for use of the drug product. These reminder advertisements shall contain only the p…

Reviewer's reasons
- The quote is verbatim operative regulatory text from 21 CFR 202.1(e)(1)(ii)(E), not drawn from an example, definition, exemption, or preamble; the locator resolves exactly to the cited subparagraph.
- applies_when is precisely justified: (e)(1)(ii) is expressly limited to 'advertisements for prescription drugs intended for use by humans presented directly to consumers in television or radio format,' which maps to promotional / broadcast / consumer. No limit is invented and none is omitted.
- authority 'binding' is correct — this is a codified CFR requirement, not guidance language ('should'/'recommends').
- determinism 'judgment' is correct — 'likely to interfere with comprehension' cannot be settled by presence/absence or literal match; it turns on degree and impression. The escalation note is consistent with this.
- Atomic: a single requirement (no interfering audio/visual elements) applied over a single defined window (during presentation of the major statement).
- Severity 'warning' is defensible: the obligation is binding but every finding rests on a likelihood-of-interference judgment rather than a countable defect.
- Overstated in one respect: the rule statement adds 'distract from' and the check reframes the test as 'distracting elements.' The regulation's only standard is elements 'likely to interfere with comprehension of the major statement.' As written, a reviewer would flag noticeable-but-non-impairing music or on-screen action, which the source does not prohibit.
- The check omits the regulation's 'alone or in combination' language, so it misses the cumulative-effect case where several individually minor elements together are likely to interfere.

Reviewer's reasons
- The quote is the operative text of 21 CFR 202.1(e)(1)(ii)(E) verbatim, and the rule statement restates it without expansion, including preserving the 'during the presentation of the major statement' temporal limit and the 'likely to interfere' (not 'present') threshold.
- The requirement is genuinely obligatory in context: (e)(1)(ii) states the major statement 'must be presented in a clear, conspicuous, and neutral manner' and then enumerates (A)-(E) as the conditions constituting that manner. (E) is therefore a binding element, not guidance, so writing it as a 'must not' is faithful rather than overstated.
- applies_when tracks the chapeau of (e)(1)(ii): 'advertisements for prescription drugs intended for use by humans presented directly to consumers in television or radio format' — hence promotional, broadcast, consumer. Notably, unlike (C) and (D), (E) is not limited to 'advertisements in television format', so extending it to radio (audio elements) as the check does is correct and not an invention.
- Atomic: a single prohibition on interfering audio/visual elements during the major statement. It does not bundle in the separate dual-modality, font/contrast, volume/pacing, or plain-language conditions of (A)-(D).
- determinism = judgment is right: 'likely to interfere with comprehension' turns on audience perception and the combined impression of elements; no literal match or presence/absence test settles it. The check and escalation note correctly flag the distinction between mere presence of competing elements and likely interference.
- authority = binding is right: this is a codified FDA regulation (21 CFR), not guidance.
- Locator 21 CFR 202.1(e)(1)(ii)(E) is exactly where the quoted sentence appears in the source text.
- Severity 'warning' is defensible: violation depends on a judgment about likely interference rather than a verifiable omission, so flagging for human review rather than hard failure is reasonable; a reviewer could justify 'error' given the binding authority, but this is within defensible range and not grounds to withhold a pass.
