Ok, so if you are incepting someone into giving you a pay raise or a dividend or options or a commission on a new project, that makes some sense to me; but if you are just working at a company and have to move mountains to convince people to do something that they will never even be able to appreciate you for it because part of the process was tricking them into thinking it was their own idea, then I guess I am saying you also need to make damned sure that you aren't going to just work for that project and have protection against being replaced on it: you need to incept the further idea that you should get a cut of the upside (which just sounds difficult in a world where you are explicitly diverting any credit for the idea to someone else).

But why would a manager reward someone with only bad and/or non-original ideas?
