Invent Options for Mutual Gain
Key Takeaway: Most negotiations fail to create value because negotiators succumb to four obstacles — premature judgment, searching for the single answer, assuming a fixed pie, and thinking the other side's problem is theirs alone — and the remedy is systematic option generation that separates inventing from deciding and exploits differences as the raw material for mutual gain.

Summary
This chapter addresses the third principle of #principlednegotiation and is arguably the most practically actionable in the book. Fisher opens with the orange parable — two children split an orange in half, when one wanted only the fruit and the other only the peel. A perfect solution existed (whole fruit to one, whole peel to the other) but they "left money on the table" because neither thought to explore what the other actually wanted. This is the #mutualgain principle in miniature: most negotiations contain far more value than either side captures because they never bother to look.
Fisher diagnoses four obstacles that prevent #creativity in negotiation. Premature judgment kills ideas before they're fully formed — under negotiation pressure, your critical mind is hyperactive and every half-formed thought gets shot down. Searching for the single answer narrows the field too early, treating negotiation as a convergent process when it should first be divergent. The #fixedpiebias convinces both sides that any gain for one is automatically a loss for the other, when in reality most negotiations have multiple dimensions where value can be created. And thinking "solving their problem is their problem" produces one-sided solutions that the other side will never accept. These four obstacles explain why most real-world negotiations produce mediocre outcomes — not because the parties lack intelligence, but because the process systematically suppresses the creativity needed to find superior solutions.
The prescription is structured in four parts. First, separate inventing from deciding through formal #brainstorming — a process with specific rules (no criticism, wild ideas encouraged, side-by-side seating facing a whiteboard, off-the-record). Fisher provides a detailed protocol for before, during, and after brainstorming that could be lifted directly into any team meeting or deal negotiation. The coal mine labor dispute example shows joint brainstorming between union and management producing ideas (joint training, a softball team, an annual family picnic) that neither side would have generated alone. The key insight is that "discussing options differs radically from taking positions" — the language shifts from assertions to questions, from closed to open.
Second, broaden options using the Circle Chart — a thinking tool that moves between four levels: specific problem → diagnostic analysis → prescriptive approaches → action ideas. You can enter at any level and shuttle between them to multiply options. The Northern Ireland education example demonstrates the power: a single idea (Catholic and Protestant teachers creating a joint history workbook) was reverse-engineered to identify the general principle ("understanding should be promoted in young children") which then generated new ideas (joint film projects, teacher exchanges, shared classes). Fisher also suggests looking through the eyes of different experts — how would a banker, psychiatrist, or football coach approach this problem? — and inventing agreements of different strengths (provisional vs. permanent, partial vs. comprehensive, contingent vs. unconditional).
Third, search for mutual gain by identifying shared interests and #dovetailing differing interests. The Townsend Oil example shows how a tax negotiation between a refinery and a city, apparently a simple zero-sum fight over dollars, becomes a partnership for industrial development when shared interests (attracting new businesses, growing the tax base) are made explicit. But the chapter's deepest contribution is the principle that "agreement is often based on disagreement." Differences in interests, beliefs, time preferences, forecasts, and risk aversion are not obstacles to agreement — they are the raw material. If you value the present more and they value the future more, installment plans work. If you're confident and they're risk-averse, contingent bonuses work. Fisher's motto, "Vive la différence!", turns the conventional wisdom on its head: differences don't just need to be bridged; they need to be exploited.
This principle connects directly to Alex Hormozi's approach in $100M Offers, where #offercreation is fundamentally about identifying what the customer values (the transformation) and what costs you little to provide. Hormozi's "value equation" — dream outcome × perceived likelihood of achievement ÷ time delay ÷ effort and sacrifice — is an applied version of Fisher's dovetailing: find the dimensions where your costs are low and their perceived value is high, then structure the deal around those asymmetries. The difference is that Fisher assumes both parties should collaborate on option generation, while Hormozi designs offers unilaterally to be irresistible.
Fourth, make their decision easy. Fisher's advice here is disarmingly practical: focus on the specific person who will say yes or no (not an abstraction like "the company"), draft a "yesable proposition" they could sign with a single word, make it easy to implement, frame it as legitimate and consistent with precedent, and focus on offers rather than threats. The insight about "helping your opposite number get new instructions" — understanding that your negotiating partner often needs to sell the deal internally — is sophisticated and underappreciated. You're not just persuading the person across the table; you're giving them ammunition to persuade their own side.
The chapter also introduces the idea that you can change the scope of an agreement to make it more attractive — fractionate into smaller pieces ("edit the first chapter for $300 and we'll see"), or expand to sweeten the pot (the India-Pakistan water dispute resolved by bringing in the World Bank to fund new irrigation projects for both nations). This flexibility in scope is a powerful tool that most negotiators overlook because they fixate on the original framing of the problem.
Key Insights
Four Obstacles to Creative Options
Premature judgment, searching for the single answer, the fixed-pie assumption, and thinking "their problem is their problem" — these four cognitive traps explain why negotiations routinely produce suboptimal outcomes. They're not character flaws but structural features of the negotiation environment (pressure, adversarial framing, ego involvement). Overcoming them requires deliberate process design, not just willpower.Differences Are the Raw Material for Deals, Not Obstacles
This is the chapter's deepest insight and one of Fisher's most original contributions. Different time preferences, risk tolerances, forecasts, and values between parties don't just need to be managed — they create opportunities. A stock trade happens precisely because buyer and seller disagree about future value. An installment plan works because parties discount future value differently. The negotiator's job is to find these asymmetries and exploit them for mutual benefit.Separate Inventing from Deciding
Creativity and judgment are incompatible processes — you can't generate wild ideas while simultaneously evaluating them. Fisher's brainstorming protocol enforces this separation structurally: no criticism during generation, evaluation only afterward. This principle applies far beyond negotiation — it's the foundation of design thinking, agile development, and any creative problem-solving process.Make a Yesable Proposition
The final test of any option: can you write it in a form where the other side's responding "yes" would be sufficient, realistic, and operational? If you can't draft that proposition, you haven't thought clearly enough about what you're actually asking for. This forces you to consider implementation, legitimacy, and the other side's constraints before presenting your proposal.Help Your Opposite Number Get New Instructions
Your negotiating partner often needs to sell the deal to their own organization. Your job is not just to persuade them but to give them arguments, precedents, and framing they can use to persuade their bosses, board, or constituency. The British ambassador's insight — "my job is helping my opposite number get new instructions" — reframes negotiation from adversarial persuasion to collaborative problem-solving.Key Frameworks
Four Obstacles to Creative Options
(1) Premature judgment — criticism kills ideas before they form; (2) Searching for the single answer — premature closure narrows the field; (3) Fixed-pie assumption — believing any gain for one side is a loss for the other; (4) "Their problem is their problem" — refusing to help solve the other side's constraints. Each obstacle has a corresponding remedy in the prescription section.Circle Chart (Four Types of Thinking)
A tool for multiplying options by shuttling between four levels: (1) Specific problem — what's wrong in the real world; (2) Diagnostic analysis — general categories and causes; (3) Prescriptive approaches — theoretical remedies; (4) Action ideas — specific, feasible steps. Enter at any level and move between them to generate new options. One good idea at any level can generate dozens at the others.Brainstorming Protocol
A structured process for separating inventing from deciding. Before: define purpose, choose 5-8 participants, change environment, design informal atmosphere, choose facilitator. During: seat side-by-side facing the problem, clarify no-criticism rule, brainstorm freely, record all ideas visibly. After: star promising ideas, invent improvements, schedule evaluation session. Can be run with your own side or jointly with the other side.Agreements of Different Strengths
When a strong agreement isn't achievable, negotiate a weaker one: substantive → procedural, permanent → provisional, comprehensive → partial, final → in principle, unconditional → contingent, binding → nonbinding, first-order → second-order. Even agreeing on where you disagree is progress.Dovetailing Differences Checklist
Systematic identification of asymmetries that enable value-creating trades. Look for differences in: interests (form vs. substance), beliefs (who's right), time preferences (present vs. future value), forecasts (optimism vs. pessimism), and risk aversion (certainty vs. upside). Each difference is a potential deal point.Yesable Proposition Test
Draft a proposal where the other side's single-word "yes" would be sufficient, realistic, and operational. If you can't write it, your thinking isn't clear enough. Forces you to consider implementation, legitimacy, the other side's internal constraints, and specific commitment language.Direct Quotes

Action Points
- [ ] In your next complex negotiation, brainstorm at least 10 possible deal structures before evaluating any of them — include creative options like performance-based terms, phased implementation, equity components, deferred payments, partial commitments, and joint ventures
- [ ] Apply the dovetailing checklist to your current pipeline: for each deal, identify where your time preferences, risk tolerance, or priorities differ from the seller's, and design terms that exploit those asymmetries
- [ ] Before presenting any offer, draft it as a "yesable proposition" — a specific document the other side could sign with a single word. If you can't write it, you don't know what you're asking for.
- [ ] Use the Circle Chart on your next business challenge: take one specific problem, diagnose the general pattern, identify theoretical approaches, then generate 5+ concrete action ideas
- [ ] Next time a negotiation stalls, check whether you're stuck in a fixed-pie frame — list the dimensions of the deal beyond price (timeline, terms, contingencies, relationship, future opportunities) and look for trades
Questions for Further Exploration
- Fisher recommends brainstorming jointly with the other side, but this risks revealing information and having ideas mistaken for commitments — does Voss's approach of using calibrated questions to make the other side generate options solve this problem more elegantly?
- The "agreements of different strengths" framework suggests that even when you can't agree on substance, you can agree on procedure — but doesn't this risk kicking the can down the road and creating the illusion of progress?
- Fisher's dovetailing principle assumes negotiators can accurately identify differences in time preferences, risk tolerance, and forecasts — but in practice, people often misrepresent these. How do you dovetail when you can't trust the other side's stated preferences?
- The Townsend Oil example transforms a zero-sum tax fight into a partnership for industrial development — but is this "expanding the pie" always possible, or are some negotiations genuinely zero-sum?
