The parties must acknowledge the fact that certain emotions are present, even when they don't see those feelings as reasonable. Dismissing another's feelings as unreasonable is likely to provoke an even more intense emotional response. The parties must allow the other side to express their emotions. They must not react emotionally to emotional outbursts. Symbolic gestures such as apologies or an expression of sympathy can help to defuse strong emotions.
Communication is the third main source of people problems.
Negotiators may not be speaking to each other, but may simply be grandstanding for their respective constituencies. The parties may not be listening to each other, but may instead be planning their own responses. Even when the parties are speaking to each other and are listening, misunderstandings may occur. To combat these problems, the parties should employ active listening. The listeners should give the speaker their full attention, occasionally summarizing the speaker's points to confirm their understanding.
