Emotions in Negotiation

Managing anger, trust, and the relationship — yours and theirs.

Traditional negotiation theory treated emotions as obstacles — irrational interference that should be suppressed. Modern research shows the opposite: emotions are central to negotiation outcomes, and managing them is a core skill.

How Emotions Affect Negotiation

Anger — Angry negotiators make more aggressive demands but also make more errors, concede less (even when they should), and damage relationships. Research by Gerben Van Kleef shows that expressing anger can intimidate a weaker party into conceding — but it backfires when the other side has a strong BATNA or when the relationship matters.

Anxiety — Anxious negotiators make lower first offers, respond more quickly to offers, and exit negotiations earlier than they should. If you know you tend toward anxiety, prepare more thoroughly — preparation is the best antidote.

Trust — Trust reduces transaction costs (less need for contracts, verification, safeguards) and enables integrative deals. But trust is built slowly and destroyed instantly. The first concession in a negotiation is a trust signal — it says "I'm willing to be vulnerable."

Satisfaction — How people feel about a deal matters as much as the objective terms. A party who feels they were treated fairly and respectfully is more likely to honor the agreement and negotiate with you again.
