With that in mind, I draw your attention to a book by Nicholas Capaldi called The Art Of Deception.more
It is essentially a practical guide to saying no.
There have been several printings but the cover of my edition makes the boast that it will teach readers to "win an argument", "persuade a skeptic" and "see through deception".
It is a masterpiece of political incorrectness that contains an abundance of underhand and undermining techniques. I like it a lot.
