Strategist observing an executive’s priorities and motivations during a private meeting.
Everyone has something that influences their decisions more strongly than everything else.
For one person, it is status.
For another, security.
Someone wants recognition.
Someone fears losing control.
Someone desperately wants approval.
Someone cares almost entirely about independence.
If you understand what matters most to someone, their behavior becomes easier to understand—and often easier to influence.
This is the central insight behind Law 33: Discover Each Man’s Thumbscrew.
The original wording sounds deliberately ruthless. In modern life, the useful lesson is not to discover vulnerabilities so you can exploit or harm people.
It is to understand motivations, incentives, fears, priorities, and pressure points well enough to predict behavior and communicate effectively.
What Does “Discover Each Man’s Thumbscrew” Mean?
Law 33 means identifying the motivations, desires, insecurities, priorities, or constraints that have disproportionate influence over a person’s decisions and behavior.
People rarely value everything equally.
Someone may care far more about:
recognition than money
security than opportunity
control than convenience
freedom than status
reputation than profit
belonging than independence
These priorities influence decisions.
If you understand them, apparently confusing behavior often becomes much easier to explain.
Understand what matters most, and you understand much of what drives the person.
What Is Law 33 of the Laws of Power?
Law 33 is commonly stated as:
Discover Each Man’s Thumbscrew.
A thumbscrew historically refers to an instrument used to apply pressure, which explains the intentionally provocative metaphor.
The strategic principle underneath it is broader:
Every person has particular motivations and sensitivities that carry unusual psychological weight.
People do not respond identically to the same incentive.
Offer additional money to someone motivated primarily by autonomy and you may achieve little.
Offer greater independence and their behavior may change immediately.
Another person might happily sacrifice autonomy for greater security.
Understanding these differences is a fundamental part of:
leadership
negotiation
management
sales
relationships
strategy
Law 33 Does NOT Mean Exploiting Trauma or Vulnerability
There is an important boundary between understanding someone and weaponizing what you learn.
Suppose someone privately reveals a serious insecurity.
Using that information later to frighten, humiliate, threaten, or control them may create temporary leverage.
It can also permanently destroy trust.
A stronger application of Law 33 is:
Understand the motivation behind behavior so you can predict decisions and create better alignment.
The information becomes strategically useful without becoming abusive.
Everyone Has Different Motivations
Imagine three employees receiving the same offer:
“Take responsibility for this new project.”
The first asks:
Will I receive recognition?
The second asks:
Will this help me get promoted?
The third asks:
Will I have control over how the project is executed?
Same opportunity.
Three different interpretations.
A manager who assumes everyone is motivated by the same reward will misunderstand at least two of them.
This is why incentives must be understood individually.
Law 33 Example: The Employee Who Wants Recognition
A highly capable employee consistently produces excellent work.
Their compensation is competitive.
Their responsibilities are interesting.
Yet motivation begins declining.
Their manager assumes:
“They probably want more money.”
But the actual issue is recognition.
Their work disappears into the organization while other people receive visible credit.
The manager could increase compensation and still fail to solve the problem.
Once the real motivation is understood, the solution becomes different:
visible ownership
public acknowledgment
presenting their own work
greater responsibility
The strategic insight is simple:
Don’t assume you know what someone values. Observe what actually changes their behavior.
Law 33 Example: The Executive Who Needs Control
You are negotiating a partnership with an executive.
Every financial term seems acceptable.
Yet they continue resisting.
Eventually, you realize the problem isn’t economics.
They fear losing control over how their brand is represented.
Instead of offering more money, you restructure the agreement:
“Your team retains approval over all public-facing brand materials.”
Resistance falls dramatically.
You discovered the actual issue.
The obvious objection is not always the real objection.
Law 33 Example: The Status-Conscious Decision Maker
A senior executive appears unusually concerned about who attends meetings, who presents first, and whose name appears on important documents.
You might dismiss this as vanity.
Strategically, however, it tells you something.
Status matters strongly to this person.
If you need their cooperation, publicly diminishing them may create disproportionate resistance.
That does not mean flattering them dishonestly.
It means recognizing that respect and position are important variables in how they interpret situations.
Law 33 Example: The Customer
A customer repeatedly asks about:
backups
guarantees
support
reliability
cancellation procedures
A salesperson keeps emphasizing advanced features.
The customer remains unconvinced.
Why?
The salesperson is selling innovation to someone primarily motivated by security.
A better conversation addresses:
reliability
risk
support
predictability
The product hasn’t changed.
The communication has.
Law 33 Example: The Negotiation
You are negotiating with a supplier.
You assume price is their main concern.
After several conversations, you discover that predictable volume matters more.
That creates a new tradeoff.
Instead of:
lower price versus higher price
the negotiation becomes:
lower unit price in exchange for greater volume certainty.
Understanding motivation creates options that weren’t visible before.
This connects directly with Law 31 — Control the Options.
Look Beyond What People Say
People do not always state their strongest motivations directly.
Sometimes they don’t fully understand them themselves.
Someone says:
“It’s about fairness.”
But perhaps recognition matters more.
Someone says:
“I need more money.”
But perhaps they primarily want evidence that the organization values them.
Someone says:
“I need more time to think.”
But perhaps they are afraid of making a decision they cannot reverse.
Words matter.
But patterns matter too.
Observe:
what makes them excited
what repeatedly frustrates them
what they protect
what they boast about
what they complain about
what they refuse to compromise on
where they spend time and resources
Repeated behavior often reveals priorities more accurately than isolated statements.
The Psychology Behind Law 33
Human decisions are shaped by multiple motivations.
But those motivations rarely have equal weight.
A person may simultaneously want:
money
autonomy
status
belonging
security
Yet one or two may dominate in a particular context.
This creates leverage points.
If autonomy is the strongest motivation, increasing autonomy may produce a larger behavioral change than increasing compensation.
If security dominates, reducing uncertainty may matter more than increasing upside.
The strategic skill is identifying which variable carries disproportionate weight.
Desire and Fear
Many powerful motivations fall into two broad categories:
What someone wants to gain.
And:
What someone wants to avoid losing.
A person may desire:
recognition
wealth
authority
freedom
belonging
achievement
Or fear losing:
status
security
control
reputation
relationships
independence
Both influence behavior.
Sometimes the fear of losing something already possessed is stronger than the desire to gain something new.
This makes loss sensitivity particularly important in negotiation and leadership.
How to Apply Law 33 in Real Life
1. Listen for Repetition
People reveal priorities through repetition.
If someone repeatedly returns to:
“How much control would I have?”
control probably matters.
If they repeatedly ask:
“What happens if this fails?”
security may be important.
If they repeatedly mention how their contribution will be recognized, status or acknowledgment may matter.
Patterns reveal emphasis.
2. Watch What Creates Emotion
Strong emotional reactions contain information.
Notice what creates:
enthusiasm
defensiveness
frustration
pride
anxiety
Do not deliberately provoke those reactions merely to test someone.
But when they occur naturally, pay attention.
3. Observe What They Protect
People protect what they value.
Someone constantly protects their calendar.
Another protects their reputation.
Another protects authority.
Another protects relationships.
Ask:
What does this person become unusually unwilling to risk?
The answer may reveal a core priority.
4. Study Their Decisions
Actions reveal preferences.
Someone may claim work-life balance matters enormously but repeatedly choose opportunities requiring extreme hours.
Another may claim money is the priority while repeatedly rejecting higher-paying roles that reduce independence.
Behavior gives you evidence.
5. Ask Better Questions
You don’t always need to infer.
Ask.
For example:
“What matters most to you in this agreement?”
“Which part of this proposal concerns you most?”
“If you could change one thing about the role, what would it be?”
“What would make this opportunity significantly more attractive?”
Good questions can reveal motivations directly.
6. Separate Position From Motivation
Someone’s position might be:
“I need $120,000.”
Their motivation might be:
“I need to feel that this role represents progression.”
Those are different.
If you understand the motivation, alternative solutions may become possible.
7. Look for Constraints
Not every thumbscrew is psychological.
Sometimes the decisive factor is practical.
Someone may have:
a deadline
limited budget
regulatory obligations
family responsibilities
contractual restrictions
resource shortages
Understanding constraints can be just as strategically valuable as understanding desires.
8. Protect What People Tell You
If someone reveals something sensitive in confidence, treat it carefully.
Information becomes more valuable when people trust you with it.
If every vulnerability they reveal becomes a weapon, they will eventually stop revealing anything.
Trust can produce better information than manipulation.
Find the Real Objection
One of the most practical applications of Law 33 is discovering what actually prevents agreement.
A person says:
“It’s too expensive.”
Maybe price really is the issue.
But perhaps:
they don’t trust the product
they fear implementation
they need approval
they don’t understand the value
they fear making the wrong decision
Reducing the price will not solve those problems.
Before trying to overcome an objection, identify it correctly.
Don’t Project Your Own Motivations
This is one of the easiest mistakes to make.
If money motivates you strongly, you may assume money motivates everyone.
If independence matters enormously to you, you may assume everyone wants autonomy.
If status means little to you, you may underestimate how much it matters to someone else.
Strategic understanding requires separating:
What would motivate me?
from:
What motivates them?
This connects directly with Law 19 — Know Who You’re Dealing With.
Use Motivation to Create Alignment
The strongest application of Law 33 is not:
Find the weakness and squeeze it.
It is:
Find what matters and align incentives around it.
Suppose you need someone to lead a difficult project.
They want greater visibility and leadership experience.
You need ownership.
They need opportunity.
The project can satisfy both.
That is more durable than forcing cooperation through pressure.
When Law 33 Can Backfire
Knowing someone’s vulnerabilities can create the temptation to overuse them.
Suppose you discover that someone is extremely afraid of losing status.
You repeatedly threaten their status whenever you want compliance.
Initially, it works.
Eventually:
resentment grows
trust disappears
information gets hidden
retaliation becomes more likely
the relationship deteriorates
Pressure points are particularly dangerous because they work.
Their effectiveness can encourage overuse.
Just because you know where pressure would work does not mean applying it is strategically wise.
Law 33 at Work
Understanding motivation makes management more effective.
One employee may respond strongly to:
recognition.
Another:
autonomy.
Another:
career progression.
Another:
technical mastery.
Another:
stability.
Managers who understand these differences can allocate:
responsibilities
incentives
feedback
opportunities
more intelligently.
Treating everyone identically is not always the same as managing everyone effectively.
Law 33 in Leadership
Leaders need to understand what motivates both individuals and groups.
During organizational change, different employees may fear different things:
losing jobs
losing status
losing autonomy
losing familiar routines
losing influence
A generic message may fail because it addresses none of these concerns specifically.
Understanding the real anxieties allows leadership to communicate more clearly.
It also helps distinguish concerns that can be resolved from resistance that cannot.
Law 33 in Business
Businesses become stronger when they understand why customers actually buy.
Customers rarely purchase merely because a product contains features.
They may want:
convenience
confidence
mastery
time
security
entertainment
status
progress
Good product positioning connects features to those underlying motivations without promising outcomes the product cannot deliver.
This connects directly with Law 32 — Play to People’s Fantasies.
Law 32 identifies the desired future.
Law 33 helps reveal which desired future matters most to this particular person.
Law 33 in Negotiation
Negotiation becomes much easier when you understand the other side’s hierarchy of priorities.
Imagine five variables:
price
timing
scope
control
commitment
You value them differently.
So does the other side.
The opportunity appears when you can give them something they value highly in exchange for something that costs you relatively little.
That is how mutually beneficial trades emerge.
Negotiation improves when you stop treating every variable as equally important.
Law 33 in Relationships
Understanding someone’s emotional sensitivities can make relationships stronger—or more destructive.
If you know someone fears abandonment, humiliation, or rejection, deliberately activating that fear to control them damages the relationship.
But understanding the sensitivity can help you communicate more carefully.
The same knowledge can produce:
empathy or exploitation.
The strategic difference is what you choose to do with it.
Weakness Is Not Always a Weakness
The term “thumbscrew” suggests vulnerability.
But the decisive motivation may also be a strength.
Someone may care deeply about:
excellence
loyalty
fairness
responsibility
family
independence
These values influence behavior just as strongly as insecurity.
So don’t search only for weaknesses.
Search for:
the thing that matters disproportionately.
That is the deeper principle.
How Law 33 Connects to Other Laws
Law 13 — Appeal to People’s Self-Interest:
You cannot appeal effectively to someone’s interests until you understand what they actually value.
Law 14 — Pose as a Friend, Work as a Spy:
Careful observation and listening reveal information that direct questioning may miss.
Law 19 — Know Who You’re Dealing With:
Understanding personality and character provides the context for interpreting motivations.
Law 27 — Play on People’s Need to Believe:
Belief and belonging can become powerful motivations for particular individuals and communities.
Law 31 — Control the Options:
Knowing someone’s priorities helps you design choices that address what matters to them.
Law 32 — Play to People’s Fantasies:
Understanding someone’s aspirations reveals which future they find most compelling.
Together, these Laws suggest a practical sequence:
Observe → listen → identify patterns → discover what matters → understand constraints → separate stated positions from real motivations → create alignment → avoid unnecessary exploitation.
Law 33 in One Sentence
Discover Each Man’s Thumbscrew means identifying the motivations, desires, fears, priorities, or constraints that disproportionately influence someone’s decisions so you can better understand their behavior and communicate strategically.
Don’t merely ask:
What are they saying?
Ask:
What matters enough to make them act?
Train Law 33 Until You Recognize the Situation
An employee asks for more money but continues sounding dissatisfied after receiving an increase.
Is money actually the main motivation?
A negotiation remains stuck even though the financial terms appear attractive.
What nonfinancial issue might matter more?
A customer repeatedly asks about reliability while you continue explaining features.
Are you selling innovation to someone who primarily wants security?
An executive reacts strongly whenever their authority appears threatened.
What does that reveal about how they interpret decisions?
Someone confides a personal insecurity in you.
Will knowing it help you communicate better—or tempt you to use pressure that eventually destroys trust?
These situations require judgment about motivation, incentives, fear, desire, constraints, trust, and influence.

Final Thought
People tell you what they want.
Watch what they protect.
Listen to what they repeat.
Notice what excites them.
Notice what worries them.
Study the choices they actually make.
Behind the visible position is often a deeper motivation.
Find it.
Understand it.
But remember:
Knowing someone’s pressure point gives you power precisely because it gives you the ability to hurt them.
You do not need to use that ability.
Often the stronger move is turning the same knowledge into alignment.
Understand what moves people.
Then decide carefully what you do with that knowledge.
