Communicating with Warmth in Distributive Negotiations Is Surprisingly Counterproductive

When entering into a negotiation, individuals have the choice to enact a variety of communication styles. We test the differential impact of being “warm and friendly” versus “tough and firm” in a distributive negotiation, when first offers are held constant and concession patterns are tracked. We train a natural language processing algorithm to precisely quantify the difference between how people enact warm versus tough communication styles. We find that the two styles differ primarily in length and their expressions of politeness (Study 1). Negotiators with a tough communication style achieved better economic outcomes than negotiators with a warm communication style, both in a field experiment (Study 2) and in a laboratory experiment (Study 3). This was driven by the fact that offers delivered in tough language elicited more favorable counteroffers. We further find that the counterparts of warm versus tough negotiators did not report different levels of satisfaction or enjoyment of their interactions (Study 3). Finally, in Study 4 we document that individuals’ lay beliefs are in direct opposition to our findings: participants believe that authors of warmly worded negotiation offers will be better liked and will achieve better economic outcomes.
