The example negotiation between Turnbull and Mrs. Jones is a template for how to overcome apparent power differences and turn positional bargaining into principled negotiation. At the beginning of the conversation, Mrs. Jones has the upper hand—she already has Turnbull’s money, and she probably thinks that nothing will happen to her if she refuses to pay it back. (In other words, she thinks that her BATNA is strong.) Accordingly, she sticks to positional bargaining, as she does not have any reason to reach an agreement rather than walk away—indeed, she probably knows that she will end up losing money in a fair agreement. In contrast, Turnbull knows that he has been overcharged in a way that is objective and demonstrable, so he wants to negotiate on principles rather than positions. His challenge is convincing Mrs. Jones to open-mindedly engage with him.
