Recognizing and interpreting non$-$spoken body language is arguably the most crucial technique in negotiations. As Peter Drucker wisely stated, "The most important thing in communication is hearing what isn't said." The ability to understand the nonverbal cues, such as facial expressions, gestures, and tone of voice, provides valuable insights into a counterparty's true thoughts and feelings. Albert Mehrabian's research reinforces the significance of nonverbal communication, revealing that $55\%$ of communication is conveyed through body language. In a negotiation setting, this technique allows negotiators to grasp the unspoken elements influencing the counterparty's stance, helping to navigate the negotiation process more effectively. Additionally, being mindful of one's own non$-$verbal cues enables negotiators to send intentional signals and manage the perception of their positions, contributing to a more strategic and successful negotiation outcome. reward this
