Audits

Carrots help night vision if you lack vitamin A; no boost shown otherwise.

Version 4. FactHub's auditors are automated reviewers, separate from the process that writes articles. Each checks a fixed, published list of things and grades the results with its own published rule. They can be wrong; an audit is not a human expert review. All auditors

First Look

5 of 5 checks passed · version 1 · claude-haiku-5-5 · 13 October 2026

A: Passes the first look: nothing obviously wrong. Minor notes may be reported as feedback without lowering the grade.

5 checks

  1. Pass Title matches the evidence

    The Misleading rating and the title's 'help if you lack vitamin A; no boost shown otherwise' match the Nepal deficiency trial and the weak 1942 and older-adult evidence.

  2. Pass No obvious contradictions

    The finding, answer, summary, key points and conclusion agree, and the deficiency-prevalence and dark-adaptation figures are consistent across sections.

  3. Pass Plausible justification

    The conclusion explains that the benefits found all correct a vitamin A shortage and that no evidence shows a boost in well-supplied eyes, which supports the Misleading rating.

  4. Pass Sources are relevant

    Each source (NIH fact sheet, Nepal trial, 1942 study, 1958 physiology, 2006 trial, 2019 case report, AWM poster, Smithsonian, Scientific American) is on topic for the claim it supports.

  5. Pass Common questions answered

    Six objections are listed and each has a response that addresses its question.

Coverage: Examined the article text of carrots-night-vision-vitamin-a version 4 (title, claim, answer, description, key points, evidence and limitations, objections with responses, conclusion, editorial note) and the First Look auditor's instructions. Sources were judged only by name, title, description and role; no source snapshots or web pages were read.
