BATNA was coined by the Harvard Negotiation Project: before entering any negotiation, you must know exactly what your best alternative is if it falls through. The stronger your BATNA, the more leverage you have; the weaker it is, the more likely you are to accept bad terms.
The key: BATNA isn't a fixed value — it has to be actively built and strengthened. Good negotiators spend serious time before the meeting improving their own BATNA and estimating the other side's. This is straight first-principles thinking — ask yourself "without this deal, what's my real situation?"
BATNA is your best fallback if the current negotiation fails. A strong BATNA gives you leverage to walk away; a weak one forces concessions. Before any negotiation, invest time in strengthening your alternatives rather than just planning your arguments at the table.
Anchoring is enormously powerful in negotiation: whoever speaks the first number sets the reference frame for the whole conversation. Research shows final settlements correlate heavily with initial anchors, even when both parties know the first number was arbitrary. The brain, processing uncertainty, can't help adjusting from the anchor — and the adjustment is almost always insufficient.
Concession strategy works in tandem with anchoring. Key rule: concessions should diminish — give 100 the first round, 50 the second, 20 the third. The pattern signals "I'm approaching my floor." Don't make even-sized concessions (100 → 100 → 100) — that tells the other side you have plenty left. Also, every concession should be tied to a reciprocal ask, otherwise it's read as a unilateral retreat.
The first number on the table disproportionately shapes the final outcome — this is the anchoring effect. Pair it with a diminishing concession strategy (give less each round) to signal firmness. Always tie concessions to reciprocal asks; unilateral concessions erode your position.
Win-Win thinking rests on one core assumption: negotiation is not zero-sum. In most negotiations, the two sides weight different issues differently — and that asymmetry is precisely where extra value lives. What you don't care much about may matter a lot to them, and vice versa. The essence of Win-Win is expanding the pie before dividing it, rather than fighting over a fixed slice.
Key techniques: (1) negotiate bundles of issues, not items one at a time; (2) understand the other side's real needs and look for complementary points; (3) creatively introduce new options. This aligns deeply with the "human-AI collaboration" mindset — AI isn't replacing the human; it's collaborating to create more total value.
Win-Win negotiation rejects the zero-sum assumption. By understanding what each side truly values — which often differs — negotiators can "expand the pie" through creative trade-offs, bundled deals, and new options that satisfy both parties beyond simple compromise.
The core insight from Getting to Yes: the "position" people state in negotiation is usually just the tip of the iceberg — beneath it sits the real "interest." A position is "what I want"; an interest is "why I want it." When two sides lock into opposing positions, it often means they're fighting over the same orange — when in reality one wants the peel and the other wants the juice.
How to unlock interests: keep asking "why is this important to you?" or "if you got this, what would it let you achieve?" This is first principles in negotiation — pierce through surface demands to underlying motivations.
Positions are what people say they want; interests are why they want it. Most deadlocks arise from clashing positions that mask compatible interests. By asking "why does this matter to you?" repeatedly, you can uncover shared or complementary interests and find solutions that satisfy both sides at the deeper level.
