Convincing speech, accompanied by expressive non-verbal components, is a whole art, mastering which is useful not only for psychologists, but also for everyone who strives to achieve success in communication. However, even without spending a lot of time studying the encoding and decoding systems adopted in a particular society, you can make a person believe you with simple techniques.
Instructions
Step 1
Focus on eye contact. People are aware that averting the eyes is evidence of lying. But this leads to the fact that too intent gaze on the interlocutor makes him feel insecure and suspect you of insincerity. Do not confuse him with excessively persistent drilling. It is enough to maintain contact, from time to time leaving your counterpart without constant visual supervision.
Step 2
Be calm and confident. The interlocutor should not get the feeling that you are trying to put pressure on him. The truth should not need an abundance of evidence, arguments. The more persistent and persistent you are, the more you try to influence the interlocutor, the faster new and new, sometimes even absurd arguments replace each other, the more likely you will be suspected, if not of deception, then at least of the fact that you yourself not very sure about the veracity of the message being delivered.
Step 3
Behave naturally. You shouldn't come across as someone who has goals other than just communication. Even if you are deliberately giving false information, try to forget about it. Stick to your normal communication style, especially if you are talking to someone close to you. Do not saturate speech and movement with symbols that are considered "persuasive", they can attract attention and make a person think that you have a reason to use them.
Step 4
Avoid intruding words into your speech that would emphasize that you are speaking the truth. This can again act, at least on a subconscious level, so that the person begins to suspect you of lying. If you do not give him a reason to think about such a possibility, he will not doubt the truth of your words, and you will not have to make any effort to make yourself believe.
