Ask "why" before proposing any solution

Understand the interest driving a position before generating any solution — solutions invented before interests are understood usually solve the wrong problem.

Why it works

Positions are surface demands; interests are the motivating needs beneath them. The same interest ("I need flexibility") can be served by many different positions ("I need to work from home" / "I need flexible start times"). By discovering interests first, the solution space expands dramatically — from "can they get their position?" to "can we meet the interest in any of several ways?"

How to do it

1. When you hear a position, ask genuinely: "What would that give you?" or "Help me understand why that matters."
2. Listen for needs, fears, and constraints — these are the interests. Positions are usually the first thing said; interests come with deeper conversation.
3. Map both sides’ interests before generating any solution option.

Evidence

The interest-position distinction is the cornerstone of integrative bargaining research. Laboratory studies show that information exchange about interests enables logrolling and higher joint outcomes compared to positional bargaining. (rct)

Interest exploration requires trust and some vulnerability. In adversarial contexts, revealing interests exposes what matters most — information that can be exploited. The approach is most powerful in cooperative or mixed-motive settings.

Common mistake

Generating solutions before completing interest mapping — the negotiation jumps to options before understanding what each side actually needs, producing compromise rather than creative gain.
