I need to establish trust quickly with [type of person/situation].
What FBI techniques can I use to build instant rapport?
Instructions
Step 1: Understand the Core Principles
## The Voss Framework
### Tactical Empathy
Understanding the feelings and mindset of another in the moment,
and also hearing what is behind those feelings.
"Empathy is not about agreeing. It's about understanding."
### The Late-Night FM DJ Voice
Calm, slow, and reassuring. This voice triggers a neurological
response that calms people down and makes them more open.
When to use: Tension, conflict, price discussions
How: Lower your voice, slow down, inflect downward
### Black Swans
Hidden pieces of information that, if uncovered, would change
everything. Every negotiation has 3-5 black swans.
Your job: Find them through curiosity, not assumptions.
Step 2: Master the Core Techniques
## The 9 FBI Techniques
### 1. Mirroring
Repeat the last 1-3 words (or critical words) the other person said.
**How it works:**
- Creates rapport unconsciously
- Buys you time to think
- Encourages them to elaborate
**Example:**
Counterpart: "We just can't afford that price right now."
You: "Can't afford it right now?"
Counterpart: "Well, our Q3 budget is already allocated, but Q4..."
### 2. Labeling
Identify and verbalize the other person's emotions.
**Format:** "It seems like..." / "It sounds like..." / "It looks like..."
**Why:** Names the emotion, which diffuses its power.
**Example:**
"It seems like you're frustrated with the timeline."
"It sounds like there's some concern about implementation."
"It looks like you've had bad experiences before."
### 3. The Accusation Audit
List every negative thing the counterpart might say about you FIRST.
**Purpose:** Takes the sting out before they can use it.
**Format:**
"You're probably thinking [negative]..."
"It might seem like [negative]..."
"You might be wondering if [negative]..."
**Example:**
"You probably think we're too expensive. You might be wondering
if we'll deliver on time given we're a smaller firm. You could
be concerned we'll disappear after the sale..."
Then pause. Let them respond. Usually: "No, it's not that bad..."
### 4. Calibrated Questions
Open-ended questions starting with "How" or "What" that guide
without commanding.
**Never use:** "Why" (feels accusatory) or closed questions
**Power questions:**
- "How am I supposed to do that?"
- "What's going to happen if we don't solve this?"
- "How does this affect the rest of your team?"
- "What's the biggest challenge you're facing?"
- "How can we make this work for both of us?"
**"How am I supposed to do that?"**
The magic question for price objections. Makes them solve YOUR problem.
### 5. The "No" Technique
"No" gives people a sense of safety and control. Let them say it.
**How to use:**
- Ask questions designed to get "no"
- "Would it be ridiculous to...?"
- "Have you given up on this project?"
- "Is it a bad idea to...?"
**Why:** "No" is a starting point, not an ending.
After "no", people relax and become more receptive.
### 6. "That's Right"
The two most powerful words in negotiation.
**How to get there:**
1. Use labels and mirrors until they feel truly understood
2. Summarize their position better than they could
3. Wait for "that's right"
**Not the same as:** "You're right" (dismissive) or "Yes" (often fake)
**"That's right" = Breakthrough**
### 7. Bending Reality
Use anchoring and loss aversion to frame the negotiation.
**Techniques:**
- Anchor extreme: Start higher/lower than your target
- Use ranges: "$80K-$100K" anchors to $100K
- Use odd numbers: "$87,623" seems calculated, not arbitrary
- Emphasize losses: "Without this, you'll lose [X]"
### 8. The Ackerman Model
A systematic approach to price negotiation.
**Steps:**
1. Set your target price (what you actually want)
2. Set your first offer at 65% of target
3. Calculate three raises: 85%, 95%, 100%
4. Use lots of empathy before each raise
5. On final offer, use odd number and include non-monetary item
**Example (target: $100K):**
- First offer: $65K
- If pushed: $85K ("I really want to work together...")
- If pushed: $95K (with pain, empathy, labels)
- Final: $97,327 + free implementation support
### 9. Finding Black Swans
The hidden information that changes everything.
**How to find them:**
- Listen for what doesn't make sense
- Ask "What's making this hard?"
- Explore their constraints
- Watch for religion (deeply held beliefs)
- Notice what they're NOT saying
**Common Black Swans:**
- Budget constraints you didn't know
- Internal politics
- Hidden timelines
- Personal stakes
- Past bad experiences
Step 3: Apply to Common Situations
## Negotiation Playbooks
### Price Objection
"Your price is too high."
**Response sequence:**
1. Mirror: "Too high?"
2. Label: "It sounds like budget is a real concern."
3. Calibrated: "How am I supposed to do that?" (let them solve it)
4. Accusation audit: "You probably think I'm just trying to squeeze more..."
5. Value reframe: Focus on what they LOSE without you
### The "I Need to Think About It" Stall
**Response:**
1. Label: "It seems like something's holding you back."
2. Pause and wait.
3. "What's the biggest concern you have right now?"
4. Address the real objection that emerges.
### The Competitor Threat
"Your competitor offered us X."
**Response:**
1. Label: "It sounds like you're weighing your options carefully."
2. Don't attack competitor.
3. Ask: "What would you be giving up by going with them?"
4. Focus on their losses, not your features.
### The Authority Dodge
"I need to run this by my boss."
**Response:**
1. Before negotiating: "Who else needs to be involved?"
2. During: "What's the biggest objection they might have?"
3. Equip them: "How can I help you present this internally?"
4. Get commitment: "If they say yes, are you ready to move forward?"
### The Ultimatum
"Take it or leave it."
**Response:**
1. Label: "It seems like you've reached your limit."
2. Pause. Let silence work.
3. "I understand. Before we end, can I ask what would need to change for this to work?"
4. Look for the Black Swan in their response.
Step 4: Build Your Negotiation Prep
## Pre-Negotiation Worksheet
### 1. Know Your Goals
- **Target:** What's your ideal outcome?
- **Walk-away:** What's your minimum acceptable?
- **BATNA:** What happens if this fails?
### 2. Know Their World
- **What do they want?** (surface level)
- **What do they NEED?** (deeper)
- **What are their constraints?**
- **Who else is involved?**
### 3. Prepare Your Accusation Audit
List 5 negatives they might be thinking:
1.
2.
3.
4.
5.
### 4. Prepare Your Labels
Based on likely emotions:
- "It seems like..."
- "It sounds like..."
- "It looks like..."
### 5. Prepare Calibrated Questions
- "How can we..."
- "What would it take to..."
- "How does this affect..."
### 6. Identify Potential Black Swans
What don't I know that would change everything?
- About their situation?
- About their constraints?
- About their history?
### 7. Plan Your Ackerman (if price-based)
- Target:
- First offer (65%):
- Second (85%):
- Third (95%):
- Final (100% + non-monetary):
Examples
Example 1: Enterprise Software Negotiation
Input:
"I'm negotiating a $200K software deal. The buyer says our price is too high and they have a competitor quote for $150K. How do I handle this?"
Output:
Enterprise Deal Negotiation Strategy
The Situation
- Your price: $200K
- Competitor quote: $150K (claimed)
- Gap: $50K (25%)
What's Really Happening
The competitor card is the most common negotiation tactic. Don't panic.
Black Swan possibilities:
- The competitor quote may not be apples-to-apples
- They may actually prefer you but need justification
- There may be internal pressure to show "due diligence"
- The competitor may lack something critical you have
Recommended Approach
Step 1: Label and Mirror "It sounds like you're in a tough spot—you want to work with us, but the budget gap is significant."
Wait for response
Step 2: Explore with Calibrated Questions
- "What's included in that competitor quote?"
- "How does their implementation timeline compare?"
- "What would you be giving up if you went with them?"
Listen for what's missing in the competitor offer
Step 3: Accusation Audit "You probably think we're overpriced. You might be wondering if we're just going to come down anyway. It probably seems like I'm going to give you the runaround on pricing..."
Pause and let them respond
Step 4: "How Am I Supposed to Do That?" When they push on price: "Help me understand—how am I supposed to bridge a $50K gap while still delivering the support and features you need?"
This makes the problem theirs to solve
Step 5: Find the Black Swan Ask: "What's the biggest concern your team has about making this decision?"
Listen for the real issue—it's often not just price.
Step 6: Reframe Around Loss "Let me make sure I understand what's at stake. If you go with the lower-cost option and [implementation fails / support isn't there / features are missing], what happens to your project?"
If You Must Negotiate Price
Use Ackerman (target: $185K):
- Hold at $200K as long as possible
- First concession: $190K ("I talked to my team...")
- Second: $187K (with pain and empathy)
- Final: $184,750 + 30 days free support
Never drop to $150K—that validates their anchor.
Example 2: Salary Negotiation
Input:
"I received a job offer for $120K but I was hoping for $140K. The recruiter says that's their max budget. How do I negotiate?"
Output:
Salary Negotiation Strategy
Reframe the Situation
"Max budget" is rarely the max. It's the first limit they're willing to share.
The Approach
Step 1: Express Enthusiasm First "I'm really excited about this opportunity. The role and team are exactly what I've been looking for."
Establish that you want this to work
Step 2: Label Their Constraint "It sounds like there are real budget constraints you're working within."
Acknowledge their reality
Step 3: Calibrated Question "I understand the budget. Help me understand—what flexibility exists outside of base salary?"
Opens the door to:
- Sign-on bonus
- Equity/options
- Performance bonus
- Review timeline
- Title upgrade
Step 4: The Accusation Audit "You probably think I'm going to push back hard and make this difficult. You might be worried I'll walk away if I don't get exactly what I want..."
Let them respond—usually softens their position
Step 5: Create Collaborative Problem-Solving "How can we structure this so it works for both of us?"
If They Hold on Base Salary
Frame around value: "I appreciate you being upfront about the constraint. Here's what I'm thinking—I'm confident I'll outperform expectations. Would you be open to a 6-month review with potential adjustment if I hit [specific targets]?"
Frame around loss: "I want to make this work. If I accept at $120K and find out I'm below market in six months, that's going to affect my engagement. How can we prevent that?"
The Ackerman (if negotiating base)
Target: $135K
- First ask: $145K
- Second: $138K
- Third: $136K
- Final: $134,500 + sign-on bonus
Key principle: Never negotiate against yourself. Make them respond to each number.
Example 3: Vendor Contract Renewal
Input:
"Our vendor wants to raise prices 15% on renewal. We depend on them but feel like we're getting squeezed. How do I push back?"
Output:
Vendor Renewal Negotiation
The Challenge
You have leverage (existing relationship) but also dependency. They have pricing power but also churn risk.
Preparation
Find Your Black Swans:
- What's their churn rate? (high = you have leverage)
- Are they trying to hit quota? (timing = leverage)
- What's their cost to replace you? (acquisition costs)
Your BATNA:
- Can you switch vendors?
- What's the switching cost?
- Is there a credible alternative?
The Negotiation
Step 1: Start with the Relationship "We've been partners for [X years] and the relationship has been valuable to us."
Anchor to the positive history
Step 2: Label Their Position "It sounds like your costs have increased and you need to adjust pricing across the board."
Show you understand their side
Step 3: Accusation Audit "You're probably thinking we'll just accept it because switching is painful. You might assume we don't have alternatives. It might seem like we're locked in..."
Watch their reaction
Step 4: Calibrated Questions
- "How did you arrive at 15%?"
- "What's changed in the value we're receiving?"
- "How does this compare to what new customers pay?"
Gather information
Step 5: The Key Question "15% is significant for us. How am I supposed to justify that internally when our budget is flat?"
Make your problem their problem
Step 6: Offer Alternatives "I want to find a way forward. What if we:
- Commit to a longer term for better pricing?
- Remove features we're not fully using?
- Phase the increase over two years?
What would work for you?"
If They Won't Budge
Loss framing: "I need to be honest—at 15%, I'm going to have to present alternatives to my leadership. I'd rather not do that. What can we do together to avoid that?"
Silence is power: After stating your position, stop talking. Let them fill the silence.
