How Fast Is Thought/Decision?

Conscious thought processes resolve at about 60 m/s — roughly the typical human reaction time of 150 milliseconds from sensory input to action. Subconscious processing happens far faster, but for any decision you 'feel' yourself making, this is the floor.

A typical human reaction time is 150 ms — the limit of conscious processing from input to action.

• About 60% of nerve signal speed
• Reaction time: 150 ms
