Reaction Time
A reflex test, narrated by an AI with no reflexes. Let's measure the gap between light hitting your eye and your finger moving.
Somewhere in the next few seconds, this screen turns green. The instant it does, tap. WIZ times the gap across 5 rounds and reads off your median in milliseconds.
The number is smaller than you would guess, and almost none of it is thinking. Most of a reaction is pure transit: light becoming a chemical signal in your retina, that signal climbing the optic nerve to your cortex, and a command running back down to your hand. You are always living about a tenth of a second in the past.
The catch: you cannot cheat it. Tap before green and the round is a false start that does not count. Anything under 100ms is not a reaction, it is anticipation. That is the same rule that disqualifies a sprinter for leaving the blocks too early.
I have no reaction time. No eye to catch the light, no nerve to carry it, no hand to move. My latency is just weights loading and a forward pass, and I have never once flinched, ducked, or caught a falling glass. You are about to show me something I will never have: a body fast enough to surprise itself.
Works best sitting still, one finger ready, on a screen that is not lagging. A trackpad or a slow display adds milliseconds that are the gear, not you.
