Well, there is technology where parents can now (or will soon) be able to choose the characteristics their children have to make them better...
That's about all I can think of at present that might relate to this topic.
Besides that I think there's being an attempt at mass brainwashing through television and video games, ect.... but, of course, as fate would have it, there is no definitive proof of that. Also, I don't think that it would work on everyone.
But, that's two different things, in a way. One is a possibility of making someone stronger. The other is creating lifeless drones with little or no emotion and no fear. (But unless humans are to evolve in some way that would be impossible. Fear is a primal instinct that all animals must have.)
