The art of reciprocation has been used by many leaders to influence people. It is covert and effective. Assume someone gives you a gift or does a favor for you without asking for something in return, doesn’t that trigger a feeling of obligation from you to return the favor? Yes it does. Well it is the same if someone shares with you something about himself/herself. On an unconscious level you would ask yourself why that person is sharing personal information with you if he doesn’t trust you. So you would open up and start reciprocating building connection and trust to that person. One technique you can use is to reveal something about yourself casually and then turn the conversation back to her. Coupled with good questions, she would usually reciprocate and start talking about herself.
