1. Express A Visible Reaction To Their Offer
This technique works best if your are up against an opponent who clearly has not done their research and thus, is unaware of their own bargaining position. Once your opponent makes and offer, express your shock and surprise that they have dared to make such and offer. You could say something like: "What was your offer again!?" If they haven't done their research well, it is likely that they will start to feel uncomfortable compromise to your demands.
2. Set The Tone Right For Each Negotiation
Setting the right kind of atmosphere for a negotiation is half the battle won. You want your opponent to be in as pleasant a mood as possible for them to agree to most, if not all of your requests. One way to do this would be to have negotiations right after a meal with your opponent.
Having a delicious meal generates positive feelings that might just carry onto the negotiation itself, giving both parties a higher chance of reaching a favorable agreement. In fact, many business deals have been negotiated over food. Such is the effect of food on persuasion that it has even been mentioned by professor Robert Cialdini in his book about the science of influence.
3. Walk Away With Power
If things just aren't going your ways, it would be better to leave rather than take the existing offer. Sometimes, walking away for now may lead to a better deal n the future. All you need the discipline to thank your opponent for their time and leave. Do not force yourself into accepting an offer that makes no sense.
4. Look At Their Body Language
Normally, people do not five away their negotiation positions during a negotiation. Doing so would immediately compromise their bargaining power. If you can read body language, you increases your chances of spotting any slip ups thy may make that can reveal their negotiation position to you.
