Question 1

A reader encounters the claim: 'This supplement is doctor-approved.' Without additional context, why is this claim difficult to evaluate?

Answer

Vague appeals to authority are difficult to verify without knowing who endorsed the product, their qualifications, and the basis for approval.

Question 2

Accepted Answer

Converging evidence from independent sources reduces the chance that any one source's bias drives the conclusion
