1. Framing. Is subtly uses emotionally charged words to shift people towards your point of view. To frame a persuasive argument, select words that conjure images (positive, negative or neutral) in the minds of your audience.
2. Mirroring. Is the practice of mimicking the movements and body language of the person you are trying to persuade. By acting as the person listening does, you create a sense of empathy. You can mirror hand gestures, leaning forward or away, or various head and arm movements.
3. Scarcity. Is frequently used by advertisers to make opportunities seem more appealing because they have limited availability. The assumption is that if a product is scarce, there must be a ton of demand for it! (Buy one now because they're selling out fast). This is a method of persuasion to which you are frequently exposed and take it into account when you make your purchase decision.
4. Reciprocation. When someone does something for us, we feel compelled to return the favor. So, if you want someone to do something nice for you, why not do something nice for them first?
5. Congruence. We all try, subconsciously, to be consistent with previous actions. A technique used by salespeople is to shake your hand as he is negotiating with you. A good way to use this yourself is to get people acting before they make up their minds. For example, if you were out and about with a friend and you wanted to go see a movie but the friend was undecided, you could start walking in the direction of the theater while they are considering it. Your friend is more likely to agree to go once he or she is walking in the direction you set.
6. Fluid speech. When we talk, we often use little interjections and hesitant phrases such as "ummm" or "I mean"… This makes us seem less confident and sure of ourselves, and thus less persuasive. If you're confident in your speech, others will be more easily persuaded by what you have to say.
7. Herd behavior. We constantly look to those around us to determine our actions; we have the need for acceptance. We are far more likely to follow or be persuaded by someone we like or by someone who we see as an authority. An effective way to use this to your advantage is to be seen as a leader. Be charming and confident and people will place greater weight on your opinion.
8. Man's best friend. To give people the impression that you're loyal, and to inspire them to be loyal to you
9. Break the touch barrier. Whether you're closing a deal or asking someone on a date, touching them (in a subtle and appropriate way) can improve your chances by subconsciously activating the human desire to bond.
Learning about the tricks of persuasion can also give you insight into when they're being used on you.
