By age group
Percentile is the share of the group slower than this time, so a lower time gives a higher percentile. “1 in X” counts the rarer side: people at or beyond this value above the median, at or under it below. Percentiles are estimated from a normal distribution per age group.
What this means
- Mean reaction time in this data rises about 20 ms per decade: 242 ms at 18 to 24, 350 ms at 65 and over. 220 ms is the 66th percentile for the youngest group and the 97th percentile for the oldest.
- Human Benchmark's numbers come from people who chose to take a reaction test, on their own screens. Display and input lag add 10 to 50 ms, so a 220 ms result partly measures your monitor.
- Five-trial averages move 20 to 30 ms between sessions. One result is a sample, not a trait.
