Black Swan Discovery
Uncover the three to five hidden pieces of information that would completely change the negotiation if revealed.
Black Swans are the unknown unknowns that, if uncovered, would completely change the course of a negotiation. Named after Nassim Nicholas Taleb's concept (and the inspiration for Voss's consulting company, The Black Swan Group), these are pieces of information that neither side may fully recognize as important. Voss hypothesizes that in every negotiation, each side possesses at least three Black Swans.
Black Swans are leverage multipliers. They work through three types of leverage: Positive (the ability to give someone what they want), Negative (the ability to hurt someone), and Normative (using the counterpart's own stated norms against them). The most powerful leverage comes from understanding the counterpart's 'religion,' their deeply held worldview, values, and self-image that drives their behavior.
The critical insight is that when a counterpart seems crazy or irrational, they almost never are. Instead, they are operating on bad information, hidden constraints, or different values than you assume. Discovering these hidden variables is what transforms a deadlocked negotiation into a breakthrough.
- Every negotiation contains at least three Black Swans per side
- Black Swans are leverage multipliers that can completely change the game
- Three types of leverage: Positive (can give), Negative (can hurt), Normative (their own standards)
- When someone seems irrational, search for hidden constraints, desires, or bad information
- Understanding your counterpart's 'religion' (worldview) is key to finding Black Swans
- Face time reveals more than research; unguarded moments are the most revealing
- People are more apt to concede to someone they share cultural similarity with
- Start with Known Knowns and Known UnknownsBefore the negotiation, list what you know (known knowns) and what you know you don't know (known unknowns). This inventory reveals gaps in your knowledge and highlights areas where Black Swans might be hiding.Pro tipUse team members as backup listeners whose job is to listen between the lines. They will hear things you miss because you are focused on the conversation.
- Identify Potential Unknown UnknownsAsk yourself: What would make their behavior make sense? If their position seems irrational, assume they have information, constraints, or values you don't know about. Use calibrated questions to explore these possibilities.Pro tipThe three most common reasons people seem crazy: they are operating on bad information, they have hidden constraints, or they have different interests than you assume.
- Understand Their 'Religion'Dig into your counterpart's worldview, values, and deeply held beliefs. These are not just about religion in the spiritual sense but about any organizing principle that shapes how they see the world and their place in it.Pro tipListen for language that reveals values: 'I believe,' 'It's important to me that,' 'We've always done it this way.' These phrases open windows into their worldview.
- Exploit the Similarity PrinciplePeople are more likely to concede to someone they perceive as similar. Research shared cultural ground, common experiences, or overlapping values. When you find common ground, highlight it.Pro tipSimilarity can be found in surprising places: shared hometowns, similar career challenges, common hobbies. Even small points of similarity create outsized trust.
- Get Face Time and Watch Unguarded MomentsTen minutes of face time reveals more than days of research. Pay special attention to the beginning and end of meetings, when people's guards are down. Off-the-record comments and hallway conversations often contain Black Swans.Pro tipTake notes immediately after face-to-face interactions. The most revealing information often comes in casual remarks that are easy to forget.
- Apply the Three Types of LeverageOnce you uncover Black Swans, apply them as leverage: Positive (offer what they secretly need), Negative (highlight what they stand to lose), or Normative (point out inconsistencies between their stated values and their actions).WarningNormative leverage is powerful but dangerous. Calling someone a hypocrite, even implicitly, can destroy rapport if not handled with empathy.
A tobacco farmer drove a tractor into a pond near the Washington Monument and threatened to blow it up. Rather than treating him as a typical terrorist, Voss's team discovered Watson's 'religion': he was a devout Christian who genuinely believed God had instructed him to protest. Understanding this worldview allowed negotiators to speak his language and eventually convince him to surrender peacefully.
A student needed his ex-boss's approval to switch divisions. By asking calibrated questions, he discovered two Black Swans: his ex-boss needed someone to help network at headquarters, and the ex-boss was up for a vice-president promotion and needed someone to lobby the CEO on his behalf.
The concept was born from the tragic 1981 William Griffin bank standoff in Rochester, New York. Griffin killed a hostage on deadline, something that had never happened in U.S. history. The FBI's known knowns (hostage-takers never kill on deadline) had blinded them to the reality that Griffin was suicidal and intended to die that day. Voss realized that overreliance on experience could be fatal, and that every negotiation contains hidden information that could change everything. He named his company The Black Swan Group and made the discovery of these hidden variables the centerpiece of his approach.
