People have a deep subconscious need to reciprocate for anything that is done to or for them. The Law of Reciprocity is one of the most powerful of all determinants of human behavior. This is because nobody likes to feel that he or she is obligated to someone else. When someone does something nice for us, we want to repay that person, to reciprocate. We want to be even. Because of this, we seek an opportunity to do something nice in return. This law is the basis of the law of contract, as well as the glue that hold most human relationships together.
The first party to make a concession is the party who wants the deal the most. You must therefore avoid being the first one to make a concession, even a small concession. Instead, be friendly and interested, but remain silent. The first person to make a concession will usually be the person who makes additional concessions, even without reciprocal concessions. Most purchasers and sellers are aware of this. They recognize that early concessions are a sign of eagerness and are prepared to take advantage of it. Be careful.
Equal or Greater
Every concession you make in a negotiation should be matched by an equal or greater concession from the other party. If the other party asks for a concession, you may give it, but never without asking for something else in return. If you don't request a reciprocal concession, the concession that you give will be considered to have no value and will not help as the negotiation proceeds. If a person asks for a better price, suggest that it might be possible but you will have to either decrease the quantity or lengthen the delivery dates. Even if the concession is of no cost or value to you, you must make it appear valuable and important to the other party or it will not help you in the negotiation.
Small Concessions lead to Large Concessions
Small concessions on small issues enable you to ask for large concessions on large issues. One of the very best negotiating strategies is to be willing to give something in order to get something. When you make every effort to appear reasonable by conceding on issues that are unimportant to you, you put yourself in an excellent position to request an equal or greater concession later.
Use Reciprocity to your Advantage
Use the reciprocity principle to your advantage. Before negotiating make a list of the things the other party might want and decide upon what concessions you are willing to give to get what you want. This preparation strengthens your negotiating ability considerably.
