I see... Everything is going well, mr man. Soon, you shall be my third commander as you have amassed another legion. The scheme is scheme is progressing strongly. They have no idea.
I had to do it. What with all the 'ruler of the world' stuff.
Anyway, the only thing that comes to mind (lol) now is something I had in school, recently.
Behavioral (?) modification. You use a system of rewarding and maybe punishing, to change someone's behaviour. When somebody (in my case, a school student, as I'm becomign a physics teacher) does something good, you reward them with something they like. If you keep that system up, the person will eventually connect the feeling they get when they get rewarded, with the action they did in the first place, resulting in an alreafy good feeling when they do something good.
I want to give some examples, but I can only think of one. Though, this does not use rewarding, which is usually a lot stronger than punishing (which is sometimes even counter-effective).
There was a school teacher, and a little boy. The boy often complained about feeling ill, having headaches, etcetera. Then the teacher got a se of colored cards with his name on it, and she places them on a table. She said that each time the boy feels sick, she will remove one of the cards. Needless to say, the boy stopped feeling sick. And it was all in his head that it was some sort of punishment!
But they who resist... They will be punished.
