  1. Never Split the Difference, In Practice
    Chris Voss’s core move is tactical empathy: name and voice the other side’s emotions so they feel understood, which lowers their defenses and opens real bargaining. The signature tools — mirroring, labeling, calibrated questions, and the accusation audit — are practitioner tactics from FBI hostage negotiation, grounded in well-established psychology of emotion and rapport rather than tested as a packaged system.
  2. Use Compromising — but know its hidden cost
    Compromise splits the difference; it’s fast, but both parties lose something and neither is fully satisfied.

  3. Habit 6: Synergize
    Combine differences so the whole is greater than the sum of its parts.

  4. Expanding the Pie: Negotiation Beyond Splitting the Difference
    Expanding the pie means trading across issues that the two parties value differently, so both sides gain more than any fixed compromise would allow. Malhotra and Bazerman’s research shows that most negotiators leave joint gains on the table because they treat every issue as a zero-sum battle.
  5. Map what you actually agree on before diving into the disagreement
    Start by explicitly building the shared map before marking where it diverges.

  6. Compromising (moderate on both)
    Split the difference when a fast, fair, good-enough solution beats holding out for the perfect one.

  7. Do a post-conversation accuracy check
    After important conversations, compare what each person thought was communicated.
    Closeness-Communication Bias
  8. Study the gap between prediction and result with honesty
    Compare what you expected to what happened, and resist the urge to explain the gap away.

  9. Contrast training
    Study pairs of similar examples that differ on exactly one critical feature to sharpen discrimination.
    Perceptual Learning: Training Your Eye Before Your Mind
  10. Run a negotiation debrief to learn what value was left on the table
    After closing, compare priorities with the other side to see the trades you both missed.
