She had been at the company for three years, had run the product launch that brought in their largest client, and was about to receive an offer for the senior role she had been told she was being considered for. When the HR manager named a salary, she said thank you and asked if she could have a few days to consider it. In those few days, friends told her to counteroffer. Her gut said don't rock the boat. She accepted the original number. Two years later, a male colleague hired into a comparable role mentioned in passing what he made. The gap was $18,000 a year. Over five years, compounded through raises that were percentages of base salary, that single unconsidered moment of non-negotiation would cost her over $100,000.
This scenario is not unusual. Linda Babcock and Sara Laschever, whose 2003 book Women Don't Ask compiled the research on gender and negotiation, found that men initiate negotiations roughly four times more often than women in comparable situations. In one study of students entering professional jobs, eight times as many men as women negotiated their first salary. The students who negotiated earned an average of $5,000 more than those who did not. The gap accumulates, with interest, for the length of a career.
But the problem is not simply one of asking. Negotiation, understood as a practice backed by several decades of serious research, is far more complex and more learnable than either the "just ask for what you want" camp or the "born dealmakers have an edge" camp suggests. The science of negotiation encompasses cognitive psychology, game theory, cross-cultural communication, and practical craft, and the practitioners who have most rigorously synthesized research and experience, from Roger Fisher and William Ury to Deepak Malhotra to Chris Voss, agree on a core set of principles that work in courtrooms, boardrooms, salary conversations, and disputes over kitchen renovation timelines.
"The most important thing in negotiation is not what you are negotiating for. It is what you will do if you do not reach agreement." — Roger Fisher and William Ury, Getting to Yes (1981)
Key Definitions
BATNA (Best Alternative to a Negotiated Agreement): Introduced by Roger Fisher and William Ury, BATNA is what you will do if the current negotiation fails. It is the primary determinant of negotiating power: a strong BATNA means you can afford to walk away from bad deals; a weak BATNA means the other party has leverage over you.
Principled negotiation: The Fisher-Ury framework that separates people from the problem, focuses on interests rather than positions, generates multiple options before deciding, and uses objective criteria as the standard for agreement rather than the relative strength of each party's will.
Anchoring: The cognitive bias by which the first number introduced in a negotiation exerts disproportionate influence over the final outcome, regardless of which party introduced it.
Tactical empathy: Chris Voss's term for the deliberate practice of identifying and naming the emotions and perspective of the other party in a negotiation, not to manipulate but to create the psychological safety that allows productive engagement.
Zone of Possible Agreement (ZOPA): The range between each party's walk-away point within which a deal is theoretically possible. If your minimum acceptable salary is $80,000 and the employer's maximum offer is $90,000, the ZOPA is $80,000 to $90,000.
Getting to Yes: The Foundation
In 1981, Harvard Law School professors Roger Fisher and William Ury published Getting to Yes, which became one of the bestselling negotiation books in history and the foundation for most subsequent negotiation education. Their central argument was that the default mode of negotiation, which they called positional bargaining, is systematically inefficient and damaging.
In positional bargaining, each party stakes out a position ("I want $90,000"), defends it, makes incremental concessions under pressure, and eventually agrees to something in the middle if agreement is reached at all. The problem is that positions conceal underlying interests, and interests are where the actual opportunities for creative, mutually beneficial agreements live.
Fisher and Ury's famous orange example: two people want the same orange, there is only one orange, and dividing it in half seems like the reasonable compromise. But if you ask why each person wants the orange, you may find that one wants the juice and one wants the rind for a cake recipe. The interests are entirely compatible. The positional framing made a non-existent conflict appear real.
Principled negotiation rests on four practices: separate the people from the problem (the relationship is not the negotiation), focus on interests not positions, invent options for mutual gain before settling, and use objective criteria (market data, expert opinion, legal standards) rather than willpower as the basis for agreement.
The Fisher-Ury framework became enormously influential and genuinely useful, though it was later challenged and extended by researchers who found that its emphasis on collaborative interest-finding underestimated the role of power, emotion, and adversarial dynamics in real negotiations.
Deepak Malhotra and Negotiation Genius
Harvard Business School professor Deepak Malhotra, with Max Bazerman, published Negotiation Genius in 2007, which drew on decades of negotiation research to extend and sharpen the Fisher-Ury framework. Malhotra's contribution was to make the psychology of negotiation more explicit and to address the situations where principled negotiation faces genuine adversarial resistance.
Malhotra distinguishes between creating value (expanding what is available to be divided) and claiming value (getting a favorable share of what is there), and argues that the most effective negotiators do both, in sequence. The mistake is to try to do them simultaneously, which produces confusion about whether you are collaborating or competing, or to focus entirely on one at the expense of the other.
His concept of the negotiator's dilemma names the tension: the behaviors that create the most value in a negotiation (sharing information about your interests and priorities, being honest about constraints) also make you vulnerable to exploitation if the other party is not reciprocating. Malhotra's recommendation is to share information about priorities and interests while being more protective about walk-away points and alternatives, and to do small tests of trust-worthiness before making larger disclosures.
The Anchoring Effect in Practice
The anchoring effect is one of the most replicated findings in cognitive psychology, and it is particularly powerful in negotiation. Adam Galinsky and Thomas Mussweiler's 2001 study in the Journal of Personality and Social Psychology showed that the first price offered in a negotiation consistently pulled the final settlement toward it, whether the anchor was high or low and regardless of how arbitrary it appeared.
The implication is direct: whoever states the first number in a negotiation establishes the anchor. Conventional advice often suggests waiting to hear the other party's number first. The research does not support this. If you can credibly anchor at the high end of a reasonable range, you should.
Several refinements make anchors more effective. Precise anchors are more powerful than round numbers. A 2006 study by Chris Janiszewski and Dan Uy found that anchors stated as precise figures ($97,500 rather than $100,000) imply that the number was derived from specific research or calculation, which gives it more persuasive weight and results in counteroffers that stay closer to the anchor. Justified anchors are stronger than bare numbers: the same salary request accompanied by market research data pulls better outcomes than the same number stated without support.
It is equally important to protect yourself against anchors set by the other party. Galinsky and Mussweiler found that a specific counter-strategy weakens anchoring: rather than focusing on the anchor number, deliberately generate evidence about why it is wrong by thinking about the most extreme alternative. If the employer opens with a low anchor, generate a list of comparable salaries in the market before responding. The effort of generating alternative information disrupts the anchor's cognitive grip.
BATNA: The Architecture of Leverage
Fisher and Ury's concept of BATNA is perhaps the single most practically important idea in negotiation. Your BATNA is what you will do if you walk away from this table, and it determines your real leverage regardless of how the negotiation is framed rhetorically.
The practical discipline of BATNA involves three steps. First, identify your alternatives: what specifically will you do if this deal does not happen? Second, develop the best alternative: before entering an important negotiation, take steps to strengthen your outside option. If you are negotiating a salary at your current employer, having a competing offer does not just improve your BATNA, it transforms the entire power dynamic of the conversation. Third, know the other party's BATNA: understanding what they will do if the deal falls through tells you how much genuine pressure they are under, which informs how hard you can push.
Negotiators who are uncertain about their BATNA often behave as if they have no alternative, making concessions they do not have to make because the anxiety of potential impasse feels worse than the agreement they are getting. Clarity about alternatives produces the confidence to hold positions that are genuinely in your interest.
Chris Voss and Tactical Empathy
Chris Voss spent more than two decades as the FBI's lead international kidnapping negotiator before writing Never Split the Difference in 2016. The book's central argument is that the rational-actor model underlying most negotiation advice, including much of Getting to Yes, misunderstands human decision-making in high-pressure situations. People are not calculating optimizers. They are emotional beings who need to feel heard before they can engage with substance.
Voss's core practice is tactical empathy: deliberately identifying and articulating the emotions and perspective of the other party, not to agree with them, but to demonstrate understanding. This is different from sympathy (which implies agreement) and from simple rapport-building (which is social). Tactical empathy, in Voss's framework, is a precision tool: when you accurately name what the other person is feeling, their emotional arousal decreases, and they become more cognitively available to the actual negotiation.
Mirroring, one of Voss's key techniques, involves repeating the last three or four words someone says as a question. "My team doesn't have capacity for that right now." "Doesn't have capacity right now?" The repetition signals attention and typically prompts the speaker to elaborate, revealing information they had not planned to share. Voss and his colleagues used this technique extensively in hostage situations where information about the hostage-taker's state of mind was often the most valuable intelligence available.
Labeling goes further: naming the emotion you observe. "It sounds like you're feeling frustrated about the timeline." "It seems like there's something about this arrangement that doesn't feel right." Labels do not have to be accurate to be useful; when they are wrong, people typically correct them, which itself reveals information. When they are right, the person feels seen, and the emotional temperature drops.
Voss's most discussed concept is the calibrated question, particularly "How am I supposed to do that?" as a response to demands or constraints that seem unreasonable. Unlike "No" (which closes the conversation) or "I can't do that" (which sounds final), "How am I supposed to do that?" is an open question that puts the problem on the other party to solve, without aggression and without conceding anything.
The Gender Gap in Negotiation
Linda Babcock and Sara Laschever's research in Women Don't Ask documented not only the frequency gap in negotiation initiation between men and women, but the structural reason it persists. It is not simply that women are less confident or less assertive. Hannah Riley Bowles at Harvard Kennedy School, with colleagues, conducted a series of studies showing that women who negotiate assertively for salary are rated more negatively than men engaging in identical behavior. Women who ask for more are perceived as less likeable and less hireable, a penalty that does not attach to men in the same way.
This creates what Bowles describes as a genuine social dilemma: women are economically penalized for not negotiating and socially penalized for negotiating, while men face primarily the economic penalty. The asymmetry is structural, not personal.
Research has identified several strategies that reduce (though do not eliminate) the social cost for women. Framing negotiations relationally reduces the backlash: "I want to make sure I'm in a position to continue contributing at the level you need" produces better outcomes than "I deserve more." Negotiating on behalf of others or as an advocate faces fewer penalties than negotiating for oneself. Acknowledging the relational context explicitly ("I know this might seem forward, but...") can paradoxically reduce backlash by signaling awareness of social norms even while departing from them.
Adam Grant's work on assertiveness adds a complementary finding: the outcomes for overly aggressive negotiators and for non-negotiators are both poor. The sweet spot is what Grant calls advocating assertively while staying attuned to the relationship, which requires a different skill than pure aggression.
Robert Cialdini's Influence Principles in Negotiation
Robert Cialdini's 1984 book Influence: The Psychology of Persuasion identified six core principles of influence that have since been extensively researched and applied to negotiation contexts: reciprocity, commitment and consistency, social proof, authority, liking, and scarcity.
Reciprocity is particularly powerful in negotiation. Making a concession creates psychological pressure on the other party to reciprocate. This is why effective negotiators often make a deliberate, named concession early, even a small one: "I'm willing to move on the timeline, so I'd like us to find a way to address the fee structure." The named trade creates a reciprocity frame that makes the counter-concession feel obligatory.
Commitment and consistency explains why getting early agreement on principles or framework, before discussing specific terms, improves outcomes. If both parties have committed to the principle that the agreement should be fair to both sides, later appeals to fairness carry more weight. If both parties have committed early to a timeline, later attempts to blow it up face resistance from the consistency motive.
Loss framing versus gain framing is perhaps the most directly applicable insight from behavioral economics to negotiation practice. Because loss aversion is real and strong, the same agreement framed as avoiding a loss is more persuasive than the same agreement framed as a gain. "Without this arrangement, you'll lose access to the early pricing we're offering" is empirically more effective than "with this arrangement, you'll enjoy our best rates."
Cross-Cultural Negotiation
Jeanne Brett's research at Northwestern's Kellogg School of Management, synthesized in Negotiating Globally (2007), documented systematic cultural differences in negotiation style that produce predictable misunderstandings when not acknowledged.
American negotiators typically value directness, information sharing, and moving quickly to deal terms. They tend to separate business relationships from personal relationships and to treat the deal itself as the primary goal of the interaction.
East Asian negotiators, particularly in China and Japan, typically invest more in relationship building before substantive negotiation begins, communicate more indirectly, and treat relationship as inseparable from deal. A American negotiator who pushes for deal terms at a first meeting may be interpreted as disrespectful; the East Asian counterpart who spends three dinners on relationship before mentioning terms may be interpreted as evasive.
Brazilian negotiators tend toward high-context, emotionally expressive communication and a more fluid concept of time. Middle Eastern negotiation often emphasizes honor and reciprocal respect as preconditions for any substantive progress.
Brett's research consistently finds that ignorance of these differences, more than specific stylistic preferences, drives cross-cultural negotiation failures. Preparation that includes learning about the other party's cultural norms, rather than assuming the American model is universal, is the single most effective intervention for cross-cultural negotiations.
Negotiation in Everyday Life
The research on negotiation is consistent in finding that most people negotiate far less frequently than they could, in everyday commercial and employment contexts, and lose substantially as a result. In a 2022 study, roughly 80 percent of consumers who asked for a better deal on an internet plan, a credit card fee, or a medical bill received a concession. The question was almost always sufficient.
The principles are the same at small scale as at large: know your BATNA, anchor appropriately, focus on interests, use tactical empathy, name trades explicitly. The inhibitions are psychological: fear of rejection, discomfort with conflict, belief that the stated price is the real price.
Deepak Malhotra's practical advice is to develop a negotiation mindset, the habit of asking whether negotiation is possible in any significant transaction, rather than treating every posted price, stated salary, and proposed contract term as fixed. Most are not.
Practical Takeaways
Know your BATNA before entering any significant negotiation. Write it down. Develop it if it is weak. Understanding your walk-away point is the foundation of every other negotiating behavior.
Go first with the anchor whenever you credibly can. Research is clear that the first number shapes the range. Anchor high (for sellers) or low (for buyers) with a precise number and a justification.
Prepare by investigating their interests, not just their positions. What does the other party actually need from this agreement? Where are there trades that could make both of you better off?
Use tactical empathy. Before pushing on substance, name what you observe about the other party's state. "It sounds like there's some concern about the timeline." The two minutes this takes regularly saves hours of positional deadlock.
Frame proposals as preventing a loss. Because of loss aversion, "without this arrangement you'll lose X" is a more persuasive frame than "with this arrangement you'll gain X."
Practice. Negotiation is a skill, not a talent. It improves with deliberate practice in lower-stakes situations (asking for a discount, negotiating a vendor contract) in ways that make higher-stakes negotiations meaningfully easier.

Frequently Asked Questions
What is the most important principle in negotiation?
Roger Fisher and William Ury's central argument in Getting to Yes is that the most important principle is separating the people from the problem. Positional bargaining, where each party stakes out a position and defends it, produces either impasse or compromise that leaves both parties unsatisfied and damages the relationship. Principled negotiation focuses instead on the underlying interests behind each party's stated positions, because interests are where creative, mutually beneficial solutions live. Two people who both claim a single window in a shared office appear to have irreconcilable positions. But one wants fresh air and the other wants natural light, meaning they have compatible interests that a position-based framing made invisible.
How do you negotiate a salary effectively?
Research points to several specific practices. First, always provide the first number if you can, because anchors set the range of the entire negotiation and the first number stated exerts disproportionate influence regardless of which party stated it. Second, anchor high but with a rationale, because anchors supported by justification are more powerful than bare numbers. Third, negotiate the full package rather than only the base salary, because employers often have more flexibility on signing bonuses, vacation, remote work, and equity than on salary. Fourth, know your BATNA, your best alternative to a negotiated agreement, because your alternative determines your actual walk-away point and your confidence in the conversation.
What psychological tactics work in negotiations?
The tactics with the strongest research support include anchoring with a precise number rather than a round one (Janiszewski and Uy found precise anchors imply more research and pull counteroffers closer), mirroring the last three words of what the other party said to encourage elaboration (from Chris Voss's FBI experience), labeling emotions by naming what the other party appears to be feeling (this reduces emotional intensity and creates rapport), and loss framing, since people are more motivated by what they might lose than what they might gain. Building rapport before making any substantive proposals also consistently improves outcomes across multiple studies.
What is BATNA and why does it matter?
BATNA, Best Alternative to a Negotiated Agreement, is the term Roger Fisher and William Ury introduced in Getting to Yes for what you will do if this negotiation fails. It is the single most important variable in determining your negotiating power. If your BATNA is strong, you can afford to walk away from a bad deal, which means you have genuine leverage. If your BATNA is weak, the other party's leverage over you is correspondingly high. Understanding your own BATNA with precision prevents you from making concessions you do not have to make. Understanding the other party's BATNA helps you assess how much pressure they are actually under.
Why do women often negotiate less than men?
Linda Babcock and Sara Laschever's research, published in Women Don't Ask (2003), found that men initiate negotiations roughly four times more often than women in comparable situations. The causes are both psychological and structural. Women often correctly perceive social costs for negotiating assertively that men do not face: Hannah Riley Bowles's research found that women who negotiate assertively for salary are judged more harshly than men doing the same thing. This creates a real dilemma, not a personal failing. Research suggests that women negotiating on behalf of others, rather than themselves, face fewer social penalties, and that framing salary negotiations as advocating for one's team or sharing the broader context reduces the social cost.
What does hostage negotiation teach us about everyday negotiation?
Chris Voss, a former FBI hostage negotiator, argues in Never Split the Difference (2016) that the tactical empathy developed in hostage situations is directly applicable to business and everyday negotiation. The core insight is that people need to feel heard and understood before they can engage productively with the substance of a negotiation. Mirroring, labeling, and the calibrated open question (How am I supposed to do that? rather than No) are all techniques that build this sense of being heard while keeping the negotiation moving. Voss's most counterintuitive finding is that pushing for agreement too early typically produces worse outcomes than slowing down, acknowledging concerns, and allowing the other party to feel understood.
How do you negotiate across cultural differences?
Jeanne Brett's research on cross-cultural negotiation, published in Negotiating Globally (2007), found systematic differences in how negotiators from different cultures approach process, relationship, and information sharing. American negotiators typically prefer direct, information-sharing approaches and move quickly to deal terms. East Asian negotiators often prioritize relationship building before substantive discussion. Brazilian negotiators tend toward more expressive emotional communication. Middle Eastern negotiators may treat relationship and deal as less separable. The most consistent finding is that ignorance of these differences, rather than specific stylistic preferences, causes the most cross-cultural negotiation failures. Preparation that includes learning about the other party's cultural norms produces substantially better outcomes.
