The service
Human Precision provides browser-based recreational performance challenges. Features may change, be interrupted or be removed.
Scores and interpretation
Scores are estimates produced under the site’s rules and are affected by hardware, software, attention, familiarity and environment. Daily Precision scores are not medical advice, diagnoses or guarantees of real-world performance. The Human Precision Reasoning Index is specific to this original question set and is not a clinical, normed or professional IQ score. An official daily score is official only within the site’s local daily game rules; it is not independently verified.
Acceptable use
Do not automate inputs, manipulate local storage or challenge URLs to misrepresent a score, interfere with the service, attempt unauthorized access or use challenge links to harass another person. Casual shared scores are not server-verified.
Limitations
The service is provided as available without warranties to the extent permitted by law. Do not rely on a score for health, education, employment or safety-critical decisions.
