Negotiation Principles

Everything Is a Negotiation

Most people think negotiation means sitting across a table haggling over price. In reality, you negotiate dozens of times a day — project scope, deadlines, responsibilities, whose turn it is to cook dinner. The principles are the same whether you're negotiating a million-pound contract or deciding where to eat.

The two dominant schools of negotiation — Harvard's "principled negotiation" (Getting to Yes) and Chris Voss's "tactical empathy" (Never Split the Difference) — offer complementary approaches. The best negotiators draw from both.

Core Concepts

BATNA (Best Alternative to a Negotiated Agreement)

Your BATNA is your best option if the current negotiation fails. It is the single most important concept in negotiation because it determines your power.

• Strong BATNA = strong position. If you have a great job offer from Company B, negotiating with Company A becomes much easier. You can walk away.
• Weak BATNA = weak position. If you have no alternatives, you're negotiating from desperation. The other side can smell it.
• Always know your BATNA before negotiating. Invest time in developing alternatives before you sit down at the table.
• Never reveal a weak BATNA. But subtly signal a strong one.
• Try to understand the other party's BATNA. Their alternatives determine their flexibility. If they have no alternatives, they need this deal more than they're showing.

Anchoring

The first number mentioned in a negotiation heavily influences the final outcome. This is the "anchoring effect" — a well-documented cognitive bias. The anchor pulls all subsequent numbers toward it.

• When possible, anchor first. If you're selling, name a high (but justifiable) price. If you're buying, name a low (but justifiable) price. The final number will be closer to whoever anchored.
• Make your anchor specific. Asking for £72,500 is more powerful than asking for £70,000. Specific numbers imply research and precision.
• Counter-anchor deliberately. If the other party anchors, don't let it pull you. Ignore their number and re-anchor with your own, supported by different criteria.

Tactical Empathy (Chris Voss)

Understanding the other person's perspective and emotions — not to agree with them, but to demonstrate that you see their world. This builds trust and disarms defensiveness.

• Labelling: "It sounds like you're concerned about the timeline." Naming someone's emotion defuses it. They feel heard, which opens them to your perspective.
• Mirroring: Repeat the last 1-3 words of what someone said, with an upward inflection. They'll elaborate, giving you more information. Simple but remarkably effective.
• Calibrated questions: Open-ended questions that start with "How" or "What." "How am I supposed to do that?" puts the problem back on the other side without creating confrontation. "What would it take to make this work?" invites collaboration.
• The accusation audit: Before the other party raises their objections, raise them yourself. "You're probably thinking this price is too high and that we're trying to take advantage of you." By voicing their fears first, you rob those fears of their power.

Principled Negotiation (Harvard Method)

Four principles from "Getting to Yes" by Fisher and Ury:

Principle	Meaning	Example
Separate people from the problem	Negotiate the issue, not the relationship. Don't make it personal.	"We have different views on the timeline" not "You're being unreasonable about the deadline."
Focus on interests, not positions	Positions are what people say they want. Interests are why they want it.	Their position: "I want £80,000." Their interest: financial security, market-rate fairness, recognition. Find the interest.
Generate options for mutual gain	Expand the pie before dividing it. Creative solutions often satisfy both parties.	Can't increase salary? Offer equity, flexible hours, a title change, professional development budget. Multiple currencies.
Use objective criteria	Base the agreement on external standards rather than willpower.	Market rate data, industry benchmarks, precedent, expert opinions. "The Glassdoor average for this role in London is..."

Salary Negotiation

The highest-stakes negotiation most people face regularly. Key principles:

• Never name a number first if you can avoid it. "I'd prefer to understand the full scope of the role before discussing compensation. What's the budgeted range for this position?"
• If forced to go first, anchor high with justification. "Based on my research of the market rate for this role and my X years of relevant experience, I'm looking for a range of £X-£Y."
• Negotiate the whole package. Base salary, bonus, equity, pension, holiday, remote work, start date, signing bonus, professional development, title. Each is a negotiable variable.
• Use the "I" not "you" frame. "I would need at least £X to make this move" is stronger than "Can you offer £X?" The first is a statement of your requirements; the second is a request they can refuse.
• Get it in writing. Verbal agreements are forgotten, misremembered, or renegotiated. An offer letter with specifics is the only thing that counts.
• Practice. Rehearse your negotiation out loud with a friend. The words that sound smooth in your head often stumble when spoken. Practice eliminates hesitation.

Negotiation Mistakes

• Negotiating against yourself: Lowering your ask before the other party has even responded. Wait for their counter.
• Splitting the difference: Sounds fair but rewards the person who started with the more extreme position. "Never split the difference" — find creative solutions instead.
• Treating it as zero-sum: Most negotiations have variables that parties value differently. Finding those asymmetries creates value for both sides.
• Neglecting preparation: Showing up without knowing your BATNA, the market rate, and the other party's constraints is like entering a chess match without knowing the rules.
• Burning the relationship for a small win: In repeated games (most professional relationships), the relationship is worth more than any single deal. Don't win the battle and lose the war.
