Because it is the dark art of manipulation for middle managers. This art boils down to creating a false reality to everyone who matters: you tell one set of lies to Bob, tailored to his personality, another set of lies to Jon, yet another set of lies to Jim, and when they come together, their vision is blurred by the lies you've skilfully created and they arrive with the decision you want.
You can up your game with tricks such as: backroom deals (give me what I want and I'll give you what you want) and blackmail (here is what I can do to you, so give me what I want). This dark art is an endless pit that to fully master you need to descend to hell.
