Scope
Human Precision publishes recreational browser tests and educational guides about performance, learning and general brain and cardiovascular health. Articles do not diagnose conditions or provide individualized treatment.
Source hierarchy
Guides prioritize public guidance from major health agencies and professional organizations, systematic reviews, peer-reviewed research and primary sources. Commercial wellness claims, supplement marketing and unsourced social-media claims are not treated as evidence.
About Braun
Braun writes and edits Human Precision guides for clarity and practical usefulness. Human Precision does not present Braun as a physician, psychologist or licensed clinician. Source links are included so readers can inspect the underlying guidance.
Corrections and limits
Health evidence changes and different studies can reach different conclusions. Wording is intentionally cautious when evidence is observational, mixed or limited. Material errors should be corrected when identified. Human Precision scores remain recreational estimates affected by hardware, software, familiarity and environment.
