Have you read Isaac Asimov's " Foundation series"?
I think you might enjoy it. It is set in the future at a time when mankind has expanded to populate much of the galaxy. They have this computer that can predict what humans will do in given conditions provided there are enough of them....so a large enough population will behave in a predictable way. It is based on a kind of pschycology and they used that to make people behave the way they wanted them to and avoid wars and such. I Don't know if something like that is ever going to be possible but thought it sounded cool. Prophecy on steroids, much better than all this ancient stuff.
