The fourth rule of Fisher and Ury’s Harvard Negotiation Project Method is based on the relevance of principled agreements and not giving in to pressure. Negotiations should be arenas for developing good arguments, and negotiators should be open to reason but closed to threats.
In the book Getting Yes. How to negotiate without giving in, Fisher and Ury establish that negotiations aim to reach intelligent and fair agreements, and a good way to achieve this is to turn to established principles, precedents, or community practices. These have an unusual power of attraction when the parties must reach an agreement.
There are two questions to ask at this point: “How do you develop objective criteria?” and second, “How do you use them in negotiation?” On the first question, Fisher and Ury consider that objective criteria need to be independent of what each party wants to achieve and need to be legitimate and practical. These criteria would fulfil an anchoring function in the negotiation, and their legitimacy would be independent of the parties.
Here, it is worth reflecting on what the philosopher Jon Elster has called the civilising force of hypocrisy, where the most powerful party defends arguments with the language of impartiality, where, in fact, it appeals to its own interests. Elster believes that, despite everything, this exercise of turning arguments into the language of fairness favours minorities.
The Harvard Method of Negotiation holds that each issue should be framed as a joint search for an objective criterion. To achieve this impartiality of the method, it is crucial to insist on sharing the search. The classic example is two people who want to share a cake. The unbiased method is for one to split the cake and the other to choose the piece they like best. This guarantees agreement with the final split.
Negotiations tend to be more complex and usually incorporate the price dimension. In the joint search for an objective criterion, a relevant question may be asked about the theory behind the price. In sales and purchases, the price theory is usually based on the various alternative offers and demands on the market, in addition to the specific proposal of the other party. This increases or decreases the parties’ bargaining power and gives arguments for their possible demands.
What is relevant is to build a scope for deliberation with the other party to see the arguments for or against each possibility. Fisher and Ury recommend “reason and be open to reasoning about which principles are more appropriate”. Talking about principles, which underlie positions, has greater persuasive power. Negotiators must be open to reasoned persuasion on the merits of each view.
This approach to reaching intelligent and impartial agreements is an attractive alternative to negotiations based on positions, threats or misinformation. Fisher and Ury argue that “never yield to pressure, only to principle.” The best way to get the other party to do something is not by forcing them, but by convincing them with good arguments in what sense the required action is also in their interest.
From this perspective, negotiations are areas of persuasion that would be based on the combination of two premises: a) Being open to reason; b) Insistence on a solution based on an objective criterion.
This is the last rule of the Harvard Method of Negotiation. Fisher and Ury’s approach allows negotiations to be approached from a constructive and cooperative point of view, where it is considered that reaching a good agreement is a joint task of both parties where the various possibilities should be explored well and on the arguments behind the interests of the parties deliberated. Sometimes, obtaining the yes is not a conquest in enemy territory but a more cooperative task to lay the foundations of mutual benefits.
