Keep assessment and inference separate
Cognitive-health questions require context. Do not treat a browser interaction, a wearable score, or an AI interpretation as a diagnosis or a comprehensive description of a person. The National Institute on Aging explains that clinicians may use several types of assessment when investigating thinking or memory problems. A website topic label does not give a tool clinical validity.
Review the claim being made
For a research article or product description, identify the exact outcome, how it was measured, and whether the conclusion concerns a study group or an individual. Avoid replacing those details with a broad phrase such as “brain performance.” For concerns affecting daily life, contact a qualified health professional rather than relying on an online estimate.
Three questions to take with you
01What was actually measured?
02Does the evidence concern a group or an individual?
03Is clinical assessment being confused with a product score?
