Where a negotiator uses numerical reasoning with facts as part of their negotiation approach, which of the following techniques will they be adopting?

The use of numerical reasoning, facts, data, and evidence to construct a persuasive argument is the technique of logic. This approach appeals to the other party's sense of reason and objectivity. By presenting a well-structured case supported by verifiable information, a negotiator demonstrates that their position is fair, reasonable, and based on reality rather than arbitrary demands. This is one of the three core modes of persuasion identified by Aristotle: Logos (logic), Pathos (emotion), and Ethos (credibility). Using facts and figures is a direct application of Logos.

A. A threat is a coercive tactic that relies on intimidation or the promise of negative consequences, not on rational or factual argument.
C. Emotion is a technique that appeals to feelings, values, or the relationship between the parties, which is distinct from a data-driven, logical approach.
D. Power is the underlying ability to influence an outcome; while expert power can be derived from facts, the technique of using those facts is logic.
