A calculator that gives you 2+2=7 and your friend 2+2=5 is just a broken calculator. Nobody shares it. Nobody argues about it. Nobody screenshots it and sends it to their group chat. It's random noise, and random noise has no social life.
That one observation is the entire product decision behind Wrongulator — a calculator that returns a wrong answer on purpose. The key word in that sentence isn't "wrong." It's "on purpose." Specifically: the same wrong answer, every time, for every person, on every device. 2+2=5, not 2+2=some number I decided three seconds ago and nobody else will ever see again.
This is what I mean when I say the wrongness has to be deterministic. The answer isn't random — it's deterministic random in JavaScript: unpredictable to a human, but perfectly reproducible from the input alone. And that single rule cascades into every engineering decision in the project.
Why Random Kills Virality
Think about how sharing actually works. Someone computes something on your tool. They find it funny. They send it to someone else. That second person clicks the link, or types the same thing, or shows their phone to a third person.
