Is 400 ms a good reaction time?
A 400 ms reaction time falls into the Below Average band — slower than the majority of test-takers. Do not over-read a single score: fatigue, distraction, and a cold start can each shift this kind of result by a wide margin. 400 ms is one of the round-number search references queried about reaction time scores. Against the standard benchmarks, your 400 ms score is 220 ms past the Elite cutoff (180 ms), 180 ms past the Fast cutoff (220 ms), and 120 ms past the Average cutoff (280 ms). The neighboring indexed buckets are 350 ms (Below Average) and 500 ms (Below Average). Take the Reaction Time Test to see how your live performance compares.
