Discover Each Man's Thumbscrew

In M&A, understand what people value most so you can lead change with empathy and effectiveness.

Everyone has a weakness, a gap in the castle wall. That weakness is usually an insecurity, an uncontrollable emotion or need; it can also be a small secret pleasure. Either way, once found, it is a thumbscrew you can turn to your advantage.

The Law in the Integration Room

During acquisitions, leaders often ask: "Why are people resisting?" Why do some embrace the future while others hesitate? Why do identical messages produce completely different reactions? The answer is surprisingly simple. Human beings rarely evaluate change objectively. We filter uncertainty through our own priorities, through our fears, through our ambitions, through our responsibilities, and through the stories we tell ourselves about what matters.

The employee saving for a child’s education experiences change differently from the entrepreneur protecting a life’s work. The ambitious graduate experiences it differently from the middle manager seeking stability. One of the greatest mistakes in M&A is assuming everyone interprets change the same way. The CFO may focus on value creation. The founder may worry about legacy. Employees may worry about stability. Customers may worry about continuity. Everyone attends the same town hall, yet everyone hears a different message.

In M&A, influence does not begin with persuasion. It begins with understanding.

The M&A Interpretation

Greene says: Discover each person’s thumbscrew. The M&A version becomes: Discover what people care about most. Because what people value deserves respect, not exploitation. Acquisitions already involve profound uncertainty. People are vulnerable. Jobs may change, identities may be challenged, and trust is fragile. Using people’s fears against them might generate temporary compliance, but it destroys long-term commitment. Great M&A leaders seek to understand what matters most to people, not to exploit them, but to support them through change.

Seven Cases from the Deal Floor

Case 1Done right

Disney–Pixar2006

The master

The Pixar creative leadership, who valued artistic autonomy above all else.

Disney could have focused exclusively on operational integration and cost synergies following the acquisition.

Instead, leadership recognized that Pixar’s leaders cared deeply about creative autonomy and preserving their unique culture.

By structuring the deal to protect that autonomy, Disney demonstrated that it understood what Pixar valued most. The acquisition succeeded because it honored those non-negotiable priorities.

Retention of key creative leadership
Autonomy
Preserved as a core deal condition
  • Leadership identified the hidden driver of success: creative freedom.
  • Successful integrations protect what the acquired team considers non-negotiable.
Key lesson

Successful integrations protect what people consider non-negotiable. Understanding motivations improves integration choices.

Case 2Done right

Microsoft–LinkedIn2016

The master

The LinkedIn workforce, who valued their distinct mission and professional identity.

LinkedIn employees highly valued their company’s mission and independent identity.

Microsoft resisted the temptation to absorb everything immediately or force a uniform corporate culture.

Leadership recognized that preserving this sense of purpose was critical to talent retention and ongoing innovation.

  • Forced assimilation often triggers an exodus of the very talent you are trying to acquire.
  • Understanding underlying motivations directly improves integration strategy.
Key lesson

Understanding motivations improves integration choices. Preserving purpose matters to talent retention.

Case 3The everyday pattern

The Founder Protecting a Legacy

The master

The founder, for whom the sale represents decades of sacrifice, not just a financial transaction.

For many founders, selling a company is not merely a financial event. It represents decades of sacrifice, relationships, identity, and history.

Advisors who discuss only valuation and earn-outs miss the deeper, more critical conversation.

The founder is often silently asking: "Will what I built still matter? Will my people be taken care of?"

Decades
Of personal history tied to the business

Core question: "Will it still matter?"
  • Financial terms are only half the negotiation; emotional terms are the other half.
  • People frequently seek meaning and continuity as much as they seek money.
Key lesson

People frequently seek meaning as much as money. Address the legacy, not just the ledger.

Case 4The everyday pattern

The Customer Who Stayed

The master

The long-standing client, who feared losing the relationships that made the partnership work.

Following an acquisition, executives enthusiastically emphasized future opportunities and expanded capabilities to a key customer.

The customer remained hesitant and distant, despite the improved offerings.

Eventually, an account manager asked a simple question: "What concerns you most about this change?"

The customer replied: "I do not want to lose the people who understand my business." The issue was not pricing or features; it was continuity. The response changed accordingly, dedicated resources were assigned, and the relationship endured.

  • Assumptions about what the customer values are often wrong.
  • Solutions improve dramatically when assumptions give way to genuine curiosity.
Key lesson

Solutions improve when assumptions give way to curiosity. Listen to the actual concern, not the one you expect to hear.

Case 5The everyday pattern

The Middle Manager

The master

The mid-level leader, who fears becoming irrelevant in the new organizational structure.

Middle managers are often portrayed in integration plans as resistant or bureaucratic.

In reality, many simply fear becoming irrelevant. Their teams depend on them, and their identities are deeply tied to their contribution.

When leaders acknowledged these specific concerns, validated their expertise, and involved them meaningfully in the design of the new processes, engagement and execution improved dramatically.

Perceived risk of irrelevance
Dramatic

  • Resistance is often misunderstood. People are not resisting change; they are protecting something they care about.
  • Involvement is the antidote to the fear of irrelevance.
Key lesson

Resistance often reflects unaddressed needs rather than pure opposition. Address the need, and the resistance fades.

Case 6The everyday pattern

The Integration Workshop

The master

The diverse group of employees, each experiencing the same merger through a completely different lens.

An integration leader divided participants into small groups and asked two simple questions: "What are you most excited about?" and "What are you most worried about?"

The answers varied enormously: career progression, customer relationships, workload, learning opportunities, team identity, and family responsibilities.

One executive later remarked: "I thought I was leading one integration. I realized I was leading hundreds of individual experiences."

The quality and targeting of leadership communication changed forever after that session.

  • A single corporate message cannot address a hundred different personal realities.
  • Empathy begins with listening, not broadcasting.
Key lesson

Empathy begins with listening. You cannot support what you do not first seek to understand.

Case 7The everyday pattern

The Watch

The master

The colleague carrying invisible priorities and memories into every professional interaction.

A young consultant noticed an older colleague wearing the same watch every day. It was old, scratched, and nothing remarkable.

One afternoon, curiosity overcame him. "Why do you still wear it?"

The man smiled. "It belonged to my father." He explained how his father had worn it throughout his career, and how it reminded him of integrity, humility, and responsibility. When difficult decisions emerged, he touched the watch before responding.

Not because it possessed magical powers, but because it reminded him of who he wanted to be. The consultant realized something profound: we rarely understand what people carry with them. The fears hidden behind confidence. The dreams hidden behind ambition. The memories hidden behind ordinary routines.

  • Years later, whenever he encountered resistance, he asked himself: "What story might I not know yet?"
  • That single question transformed the way he led.
Key lesson

Every person carries invisible priorities. Respect begins by seeking to understand them.

The Four Practices of Human Understanding

Together, these practices create empathy with intention.

  1. 1
    Listen before persuading

    Seek understanding before seeking agreement. You cannot address a concern you have not taken the time to hear.

  2. 2
    Identify what matters most

    Look beyond the surface. Is their primary driver security, growth, legacy, purpose, or belonging? Tailor your approach to that specific driver.

  3. 3
    Adapt your approach

    Different people require different conversations. A one-size-fits-all communication strategy is a strategy that fits no one perfectly.

  4. 4
    Never exploit vulnerability

    Use your insight to support people through transition, not to manipulate them into compliance. Trust, once broken by manipulation, is rarely rebuilt.

How to Apply This at Your Level

Senior

Do not assume one message reaches everyone equally. Tailor your communication and structural decisions around the diverse realities of your key stakeholders.

At every level, the discipline is the same. Stop communicating only to audiences. Start understanding individuals.

The Beautiful Paradox

This law contains one of the deepest paradoxes in leadership. People often believe influence comes from having the right answers. Yet, influence frequently begins with asking the right questions. Meanwhile, those who seek leverage over others often lose trust, while those who seek understanding gain it.

The same psychological insight can manipulate. Or heal. The difference is intention.

Every acquisition is ultimately experienced one person at a time. Through the employee wondering whether her role still matters. Through the customer hoping familiar relationships endure. Through the founder protecting a legacy built over decades. Through the manager seeking relevance. Through the graduate searching for opportunity.

The leaders who navigate these moments wisely understand that people rarely resist change simply because they dislike it. More often, they are protecting something precious: stability, identity, purpose, or hope. The responsibility of leadership is not to exploit these truths. It is to honor them. To ask questions before offering solutions. To replace assumptions with curiosity. To recognize the humanity beneath every stakeholder category.

"Help me understand what matters most to you."

Because influence built through manipulation eventually fractures. Influence built through understanding endures. In M&A, people do not need leaders who know how to push their buttons. They need leaders who care enough to understand why those buttons exist in the first place. Power gives you access to people’s vulnerabilities. Character determines what you do with that access.

Law 33 of 48

Discover Each Man's Thumbscrew

In M&A, understand what people value most so you can lead change with empathy and effectiveness.

In M&A, the strongest leaders are not those who discover where to apply pressure. They are the ones who understand where care is most needed.

Dealmaker’s Reflection

Before your next meeting on a live deal, ask yourself:

  • 1.Am I assuming everyone interprets this change the same way I do?
  • 2.What is the unspoken fear or priority driving the resistance I am currently seeing?
  • 3.Have I taken the time to ask "what matters most to you" before offering a solution?
  • 4.Am I using my understanding of people to support them through transition, or merely to manipulate their compliance?
