What is a good reaction time?
Short answer: average human visual reaction time is around 250 milliseconds. "Good" is 200–240 ms. "Fast" is 180–200 ms. Below 150 ms is either elite athletic-level or a false start (you guessed).
Benchmarks
| Time | What it means |
|---|---|
| < 150 ms | Usually a false start — faster than human perception |
| 150–180 ms | Elite: pro gamers, sprinters, boxers |
| 180–220 ms | Fast: athletes, esports players, well-rested adults |
| 220–280 ms | Average: most healthy adults |
| 280–350 ms | Slightly slow: tired, distracted, older adults |
| > 350 ms | Something's off — fatigue, alcohol, or low attention |
Why 250 ms?
Reaction time is the sum of several physiological steps:
- Perception (~100 ms): light hits your retina, the signal travels through the optic nerve to the visual cortex.
- Recognition (~50 ms): the brain recognises "signal" rather than noise.
- Decision (~50 ms): you commit to a motor response.
- Motor execution (~50 ms): motor cortex signals travel down the spine to the muscles, which contract.
That adds up to about 250 ms on a healthy, rested human. Training can trim the recognition and decision phases (you can't speed up nerve conduction), which is why elite athletes get to 180 ms.
These figures track closely with the academic literature. Robert J. Kosinski's widely cited 2008 review of reaction-time research at Clemson University found average simple reaction time to a visual stimulus is about 190 ms, versus roughly 160 ms for an auditory stimulus — visual signals simply take longer to travel from the retina to the visual cortex than sound takes to reach the auditory cortex. At the elite end, a 2011 analysis of over 400 Olympic sprinters at the Beijing Games found a mean "fastest" reaction time off the blocks of 166 ms for men and 189 ms for women (Lipps, Galecki, & Ashton-Miller, PLOS ONE, 2011) — which is why World Athletics disqualifies any sprinter who leaves the blocks in under 100 ms as a false start; the rule is based on research showing the human brain cannot process and act on the starting signal that fast.
Why is my reaction time worse at night?
- Fatigue slows perception
- Attention drifts after long tasks
- Caffeine wears off
- Lower arousal state = slower decision phase
You'll notice this in Cowboy Quick Shot too: a fresh morning run is typically 20–40 ms faster than the same run at 11pm.
The difference between tap-based and motion-based measurement
Most online reaction-time tests measure how fast you click a mouse or tap a screen. That's measuring the decision phase more than the full response — your finger is already on the button.
Cowboy Quick Shot measures the full chain: you have to perceive the signal, decide to move, lift your arm, and rotate the phone. That's why scores here are typically 30–60 ms slower than a pure tap test. It's not worse — it's a more complete measurement.
Can you actually improve?
Short answer: yes, but only a little. Most of your reaction time is wired in neurologically. What you can do:
- Sleep. The single biggest short-term impact.
- Caffeine. Typically knocks 10–20 ms off for an hour or two.
- Practice. The first 50 runs improve fast as you learn the signal. After that, gains flatten.
- Warm-up. A few non-counted runs before a real attempt makes a real difference.
You're unlikely to take 30 ms off your long-term average no matter what you do. But you can definitely beat your Tuesday night time on Saturday morning.
Bottom line
If Cowboy Quick Shot says you're hitting 230 ms, you're solidly above average. If it says 200 ms, you're genuinely fast. If it keeps saying < 150 ms, stop guessing and wait for the signal.
