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. 350 ms is the 2nd percentile for the youngest group and the 50th 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 350 ms result partly measures your monitor.
  • This is also roughly where everyone lands after a short night or two drinks. Test rested, then judge.
