Not once in the original edition of Getting to Yes: Negotiating Agreement Without Giving In, which was published in 1981, was the word “brain” mentioned. Certainly, the “mind” was invoked several times to discuss the psychological aspects involved in negotiation. The absence of the “brain” is to be expected, as neuroscience didn’t reveal insights into negotiation and money usage until the mid 2000s, after functional magnetic resonance imaging (fMRI) was introduced a decade before.
