Does anger affect you when negotiating? When negotiating, no matter what occurs in the negotiation session, you should always keep your end goal in mind. You should not allow yourself to lose sight of your goal as the result of what your opponent says or does. In most negotiation situations, when people become angered, they become vengeful, immobile, and very spiteful in their position. Once that occurs, its difficult to focus on what you're negotiating for, let alone why you're negotiating.
Unless you're aware of how to use anger when negotiating, don't let anger affect the outcome of your negotiations. If you find yourself becoming angered by an occurrence, stop and take a time out. You can also use the time out to regain your sense of direction. Try to maintain enough outward appearing control so as not to allow your opponent to glimpse your mental state of mind. Don't let your opponent know that you've become angered. If you do, he will get insight into how he can push your buttons and thus, he can manipulate you.
If you are using anger to enhance your negotiation position and thus you're using anger as a negotiation tool, make sure you're using it to your advantage. As I indicated above, if someone senses how they can reposition you by angering you, they can manipulate you. You can do the same thing to someone else, but if you do, be prepared to adjust their state of mind to get them back on the intended track that track being your end goal.
