How does Reaction Time relate to General Intelligence (IQ)?

Psychometric research (including work by Arthur Jensen and Ian Deary) demonstrates a consistent link between simple visual-motor reaction time and general cognitive ability (the g factor). Faster neural transmission correlates with higher mental processing efficiency and working memory capacity.

Human Reaction Time Benchmarks

• 150–215 ms: Esports pro and fighter-pilot tier.
• 215–260 ms: Sharp, well-rested adult performance.
• 260–310 ms: Global median (accounting for 15–30 ms display and mouse latency).
• 310+ ms: Indicates fatigue, distraction, or high device input lag.
