How do 20Q applications/toys know what I'm thinking?

Asked by troubleinharlem (7981points) November 24th, 2009 from IM

I’ve always wondered that. I mean, there are millions of things out there. How does it always get it right? Or at least, get it close?

From Wikipedia: “Mathematically, if each question is structured to eliminate half the objects, 20 questions will allow the questioner to distinguish between 1,048,576 subjects”

@troubleinharlem This is why you should always wear a tinfoil hat.

I heard rumors that parts of David Copperfield’s soul has been harnessed in those toys. The cheaper ones are powered by the devil himself.
Dangerous stuff.

They are SKYNET applications. Use caution.
