It's almost a corollary to how a lot of magic tricks work. Sure, you probably could sneak a card from one place to another, but why not just have a second card?

You could predict someone's behavior, but why not simply hedge against every possibility?

Magic does involve a good amount of sleight of hand, but it mostly relies on getting people to accept flawed premises. The most essential part of any given trick is the bit where you tell them what's going to happen: even as they reject it and try to bring skepticism to bear, they're often working off of (carefully placed) incorrect assumptions.

One saterical German book about about a communist cangoroo introduced the idea of a dirty bomb. Basically you collect as many hair, skin cells and other human remains of as many humans as you can find. And at the end of your crime you let it explode.
