Here is the biggest secret of persuasion: intonation. This is one technique that nobody can detect, because it is a covert persuasion technique disguised as normal conversation.
In NLP we recognize 3 patterns of intonation:
When you form a question the end of the sentence is usually expressed in a rising pitch.
Express out loud any question and you’ll notice how the whole sentence might sound in your normal pitch, but the end of it, right near the question mark, is always higher in pitch, isn’t it?
When you form a statement, however, the whole sentence is usually expressed in the same pitch.
You might have “ups” and “downs,” but whatever you say can be easily distinguished from a question or a command.
For the purpose of persuasion, you ought to begin using only statements before moving on to questions and commands.
The biggest mistake people make when they want to get another person to do something is to form a command in an authoritative voice. That’s the wrong approach simply because nobody likes to be told what to do! When you form a command, the end of the sentence usually drops in pitch.
To make it effective, use the “polite” hypnotic command forms, such as: “Could you please…?” (regular pitch) + “sign here” (lower voice).
