Negotiation isn't rational problem-solving – it's emotional intelligence applied tactically. Tactical empathy (labeling emotions, mirroring, calibrated questions) gives you leverage because people need to feel understood before they'll move. "No" is the start of negotiation, not the end – it makes people feel safe and in control. Calibrated questions ("How am I supposed to do that?") force the other side to solve your problems. The Ackerman model anchors effectively. Black swans – unknown unknowns about the other side's situation – are where the real leverage hides.
