“Nicht glauben. Nicht verwerfen. Prüfen. Messen. Verstehen.” This is our starting point when an intriguing health claim asks for belief before it offers evidence.
Begin with the exact claim
An advertisement, an anecdote and a measured result are different kinds of material. A useful inquiry records the wording, the date and the source, then asks which part can actually be checked.
The question should be specific enough that evidence could change the conclusion. If a device claims to measure something, its stated purpose and accuracy are part of that question.
Follow the document
A certificate needs its complete pages, the identity of the sample and the scope of the test. A study needs its methods and its limitations. A conclusion should explain how far those documents support the claim.
Missing material should remain an open question. Requests for clarification should be factual, and a response that changes the picture should be recorded alongside the original assessment.
Care shapes the investigation
This is an approach to examining evidence and advertising. Individual treatment decisions do not belong in a public project notebook.
Published case notes will need their own source check, dates and careful editing. Private medical histories and personal correspondence remain outside this collection.
