Blog post 2: What is a good reaction time? Benchmarks by age and profession
Baseline human reaction time
Simple visual reaction time for healthy adults averages 200–250 ms. College-age individuals average ~190 ms for light stimuli (Welford, 1980). Simple auditory reaction time is faster at ~160 ms — roughly 30–40 ms quicker than visual. Touch stimuli elicit responses at ~150 ms. Choice reaction time (multiple stimuli requiring different responses) ranges from 300–500 ms depending on the number of choices, following Hick's Law (RT increases logarithmically with choice count). The absolute physiological floor for human reaction is approximately 100 ms.
The two key age-related studies
Der & Deary 2006: Published in Psychology and Aging 21(1):62-73. Sample: 7,130 adults from the UK Health and Lifestyle Survey (HALS). Conducted at MRC Social and Public Health Sciences Unit, University of Glasgow (Der) and University of Edinburgh (Deary). Simple RT was relatively flat until ~age 60, then increased notably. Choice RT increased continuously throughout adulthood. Males were slightly faster than females, with the gender gap larger for choice RT.
MindCrowd / Talboom et al. 2021: Published in npj Aging and Mechanisms of Disease 7, Article 14. Lead author Joshua Talboom (TGen postdoctoral fellow); senior author Matt Huentelman (TGen Professor of Neurogenomics, MindCrowd founder). Sample: 75,666 MindCrowd participants (47,700 women, 27,966 men, ages 18–85) plus 158,249 from the UK Biobank (ages 40–70) — combined n > 233,000. Key findings: RT slowed by ~7 ms per year of age. Men were 34 ms faster than women. College degree holders were ~32 ms faster than those without a high school diploma. Smokers were 7 ms slower, plus 0.57 ms additional per year. Stroke history added 20 ms. Diabetes added 11 ms.
Approximate reaction time by age decade (simple visual RT, synthesised from multiple sources)
| Age range | Approx. average |
|-----------|----------------|
| 10–19 | 200–240 ms |
| 20–29 | 200–230 ms (peak) |
| 30–39 | 220–250 ms |
| 40–49 | 240–270 ms |
| 50–59 | 250–290 ms |
| 60–69 | 270–320 ms |
| 70+ | 300–350+ ms |
Peak performance occurs in the late teens to mid-20s. Thompson et al.'s study of 3,305 StarCraft 2 players (ages 16–44) found cognitive/RT decline beginning as early as age 24. By age 70, RT is approximately 30–50% slower than at age 20.
Reaction time by profession
Pro gamers: Typical range 160–180 ms on simple RT tests. Elite players occasionally hit 130–150 ms. Average recreational gamers score 250–300 ms. Bickmann et al. (2021, International Journal of eSports Research) found no significant difference in simple RT between professional esports players (mean 249 ms) and traditional sports athletes (mean 256 ms) — suggesting pros excel through consistency, anticipation, and pattern recognition rather than raw speed.
F1 drivers: Race-start reaction times typically 200–300 ms. Lewis Hamilton averages ~200 ms; Michael Schumacher averaged ~160 ms; Ayrton Senna ~170 ms. Valtteri Bottas recorded 0.04 seconds at the 2019 Japanese Grand Prix (almost certainly anticipation, not pure reaction). 2024 season averages: Hamilton 0.26s, Piastri 0.26s, Norris 0.27s, Verstappen 0.28s.
Fighter pilots: RT of 230–250 ms on average (U.S. Naval Institute, Proceedings, January 2017) — the same range as the general population. Pilots rely on anticipation, pre-planned responses, and training rather than exceptional raw RT. As one experienced fighter pilot put it: "I know to 'respond' and not to 'react.'"
Olympic sprinters: Mean start RT at Beijing Olympics was 166 ms (males), 169 ms (females). The IAAF false-start threshold is 100 ms. Elite athletes approach 100–120 ms in trained auditory contexts. Boxers average ~110–120 ms.
Cricket and baseball: Professional cricket batsmen show ~200 ms RT when batting (Land & McLeod, 2000). A 150 km/h delivery reaches the batsman in ~0.42 seconds. A 100 mph baseball pitch reaches the batter in ~400 ms; batters need ~200–250 ms RT plus ~100–125 ms for swing execution.
Military/special forces: No documented evidence of superior raw RT. Lieberman et al. (2002) studied Navy SEALs; Kamimori (2015) studied 20 Special Forces personnel. Both focused on how caffeine maintains RT under sleep deprivation rather than baseline superiority.
Factors affecting reaction time
Sleep deprivation: Adds roughly 50–100 ms of lag. Stanford research (Powell, 1999) found sleep-deprived individuals performed comparably to legally drunk subjects on RT tests. Dutil (2025) found chronic short sleepers show ~20% increased RT.
Caffeine: A 2025 meta-analysis (31 trials, n=1,455) found significant RT improvement (effect size g=0.28), with higher doses (≥200 mg) producing greater effects. Typical improvement: 10–50 ms depending on dose and individual. In esports-specific testing (Frontiers, 2024), both 1 mg/kg and 3 mg/kg caffeine significantly improved PVT reaction time in FPS players.
Alcohol: At BAC 0.08% (US legal limit), RT slows by ~120 ms on average — roughly 40% slower. At highway speeds, this translates to ~12 additional feet before braking.
Practice/training: RT is partially trainable (40–60% of variation). Young adults can improve 10–15% with 2–4 weeks of training; older adults can gain 20–30%. Most people hit a hard cap around 190–200 ms.
Human Benchmark statistics
The site reports a median of 273 ms and a mean of 284 ms across 81+ million clicks. The right-skewed distribution reflects device latency adding 20–50 ms to biological RT. Approximate performance tiers: <150 ms exceptional/elite, 150–180 ms excellent, 180–200 ms very fast, 200–250 ms above average, 250–300 ms average, >300 ms below average.
Gender differences
Males are consistently faster by a small margin. MindCrowd found men 34 ms faster (9.63% difference). A historical meta-analysis by Silverman (2006, Sex Roles, n=15,003) found the gap has narrowed over time, attributed partly to women's increasing participation in fast-action sports. Der & Deary (2006) found the smallest gender difference on simple RT (a few ms) and the largest on choice RT. Explanatory factors include testosterone levels, speed-accuracy tradeoff preferences (women tend to prioritise accuracy), and socialization differences.
