How this reaction test is scored
Your median response time is converted into a 0-1,000 task score. Variation between trials can reduce the result, so fast and repeatable performance matters more than one unusually quick response.
Why device differences matter
Displays, operating systems, browsers, mice and touchscreens all add latency. Use the same device and browser when comparing your own progress.
How to use your result
Treat the score as a recreational browser benchmark. Repeating the task can improve familiarity with this specific test, but it should not be used for medical decisions or intelligence claims.
