Final answer:
To uncover a negotiator's interests and concerns, one must clarify why these are important, facilitating a move beyond mere positions towards a more in-depth, beneficial negotiation.
Step-by-step explanation:
The key to finding a negotiator's interests and concerns when he or she states a position is to clarify why the interest or concern is important. By asking probing questions and actively listening, a negotiator can uncover underlying issues and better understand the other party's true needs and wants. This allows for the negotiation to move beyond positions to a more constructive discussion about interests, which is more likely to lead to a mutually beneficial agreement.
