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

  3. Use Compromising — but know its hidden cost
    Compromise splits the difference; it’s fast, but both parties lose something and neither is fully satisfied.
    The Thomas–Kilmann Conflict Mode Instrument (TKI)
  4. Compromising (moderate on both)
    Split the difference when a fast, fair, good-enough solution beats holding out for the perfect one.
    The Five Conflict-Resolution Styles
  5. 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.
  6. Build branches that are MECE at every level
    Ensure each set of branches is mutually exclusive (no overlap) and collectively exhaustive (nothing important missing).
    Issue Tree Analysis
  7. Write contingent contracts when forecasts disagree
    If you and the other side have different predictions, let the outcome decide who was right.

  8. Eliminate split-attention effects
    Keep physically or conceptually related information together so learners don’t pay a working memory tax to integrate them.
    Cognitive Load Theory: Learning Within Working Memory Limits
  9. Use the 1/N rule for diversification under deep uncertainty
    When you cannot estimate the value of each option reliably, spread resources equally.

  10. Collaborating (assertive and cooperative)
    Work the underlying interests until you find a solution that genuinely meets both sides’ needs.
