The document provides techniques for persuasive salesmanship, referred to as "black hat" persuasion. It discusses the importance of the persuader's state of mind and physiology. It also presents beliefs that a black hat persuader holds, such as that any objection is an opportunity to make a sale. The document recommends using language and phrases that appeal to the unconscious, such as "trance words", to bypass logical objections. It also presents "agreement frames" as a technique to appear to agree with an objection while actually redirecting the person's thinking. The overall aim is to close the deal through bare-knuckle persuasive methods.
