Which criterion best evaluates web-based health information?

• A. Up-to-date/current info
• B. Based on scientific evidence
• C. Original source listed
• D. Supported by facts

Answer: (B)

Evaluating web-based health information relies on whether the claims are grounded in scientific evidence. When information is based on scientific evidence, it has been tested and supported by research methods, data, and peer review, making the conclusions more reliable and less prone to bias or misinterpretation. It allows you to check how conclusions were reached, understand the study design, evaluate the strength of the results, and see if findings have been replicated or supported by higher-quality sources like systematic reviews or clinical guidelines.

Up-to-date information is important, but currency alone doesn’t guarantee accuracy. An article can be current yet still rest on weak or unsubstantiated claims. Having the original source listed helps you trace the claim, but the origin could be a preliminary report, opinion, or misinterpretation if it isn’t backed by solid evidence. Being “supported by facts” sounds good, but without knowing what kind of evidence underpins those facts, it can be vague or misleading. In contrast, information backed by scientific evidence demonstrates a clear link to methodologically sound research, which is the most trustworthy standard for health guidance.
