The encyclopedia of things people get wrong
Everybody knows Napoleon was short, the Great Wall is visible from space, and you swallow eight spiders a year in your sleep. Everybody's wrong. Wilkipedia is a cheerful, fact-checked tour of the misconceptions we all share, the memories we all misremember, and—new for the AI age—the confident nonsense that chatbots make up.
🎭 Wilki, not Wiki. We're an independent, tongue-in-cheek myth-busting project—not Wikipedia, not affiliated with any encyclopedia. The facts here are real and checkable; the attitude is our own.

Myth
The claim: You only use 10% of your brain.
Actually: You use virtually all of it. Brain imaging shows activity across the whole brain, and there's no dormant 90% waiting to unlock psychic powers. The myth is pure Hollywood.
Myth
The claim: Goldfish have a 3-second memory.
Actually: Goldfish can remember things for months and can even be trained. The three-second gag is a slander against a surprisingly capable fish.
