Reaction time, explained properly
Everything we figured out building the tests (the real numbers, what they mean, and how to get faster), with the studies cited so you can check us.
The Science of Reaction Time: What Really Happens
The science of reaction time: light hits your eye, your finger moves a quarter-second later. See the chain in that gap and why the slowest part surprises you.
