Persuasion is the art of convincing someone to do something or agree with something by using logic, emotion, and evidence. There are many techniques you can use to influence others, such as reciprocity, scarcity, authority, consistency, liking, and consensus. For example, you can use the principle of reciprocity by offering something of value or help before asking for something in return. With scarcity, you can highlight the urgency, exclusivity, or uniqueness of your offer or request. Authority involves demonstrating your expertise or credentials. Consistency means asking for small or easy commitments first and gradually increasing them. Liking requires building rapport and finding similarities with your audience. Finally, consensus involves showing social proof or statistics that support your argument.
