Law 17: Keep Others in Suspended Terror: Cultivate an Air of Unpredictability — Meaning, Examples & How to Apply It
Executive considering multiple strategic options while his team analyzes the problem.
When people can predict every move you make, they can prepare for you.
Consistency is usually valuable.
People want reliable employees, stable leaders, trustworthy partners, and predictable systems.
But strategic predictability is different.
If competitors know exactly how you’ll respond, negotiators know exactly where you’ll concede, or colleagues know you’ll always accept the same treatment, they can plan around you.
Sometimes a small amount of uncertainty creates leverage.
This is the central lesson behind Law 17: Keep Others in Suspended Terror: Cultivate an Air of Unpredictability.
The original title is intentionally extreme. In modern life, the useful principle isn’t about terrorizing people. It is about avoiding patterns so rigid that others can anticipate and exploit your behavior.
What Does “Cultivate an Air of Unpredictability” Mean?
Law 17 means avoiding complete predictability so that other people cannot confidently anticipate every decision, response, or limit you have.
Predictability gives others information.
If someone knows:
you always concede
you always answer immediately
you never walk away
you always choose the safest option
you react emotionally to the same provocation
they can build their strategy around your behavior.
Uncertainty removes some of that advantage.
The objective is not random behavior.
It is controlled unpredictability.
Your principles can remain consistent while your tactics remain flexible.
What Is Law 17 of the Laws of Power?
Law 17 is commonly summarized as:
Keep Others in Suspended Terror: Cultivate an Air of Unpredictability.
The underlying strategic principle is simple:
Patterns can be exploited.
Consider a tennis player who always serves in the same direction under pressure.
Even if the serve is excellent, opponents eventually anticipate it.
The solution isn’t to serve randomly without skill.
It’s to develop several credible options.
The same applies to strategy.
If other people cannot know with certainty which reasonable option you’ll choose, they must prepare for more possibilities.
That increases their uncertainty while preserving your flexibility.
Law 17 Does NOT Mean “Behave Randomly”
Randomness is not power.
Imagine a manager who:
praises an employee today
punishes the same behavior tomorrow
changes priorities without explanation
cancels commitments unexpectedly
reacts differently depending on mood
Employees may indeed become uncertain.
But they don’t necessarily respect the manager.
They may simply stop trusting them.
That’s instability, not strategic unpredictability.
A stronger distinction is:
Be predictable in your principles. Be less predictable in your tactics.
People should know that you:
keep important commitments
maintain standards
act rationally
respect legitimate boundaries
They don’t need to know exactly how you’ll respond to every strategic situation.
Law 17 Example: The Negotiation
Imagine you’ve negotiated with the same supplier several times.
Every time, the pattern is identical.
They propose a high price.
You object.
They reduce it slightly.
You negotiate again.
Eventually you accept.
After several negotiations, they’ve learned something:
You always accept eventually.
Now suppose during the next negotiation you calmly say:
“That doesn’t work for us. We’ll use the alternative.”
And you actually leave.
The supplier must update their assumptions.
Next time, they can no longer treat your objections as automatic theater.
Your behavior now contains uncertainty.
This connects with Law 8 — Make Other People Come to You.
The ability to stop chasing an agreement can shift leverage.
Law 17 Example: The Competitor
Suppose your competitor knows that whenever they reduce prices, you immediately reduce yours.
They can control your behavior.
Their move produces your move.
Instead, you might respond differently.
One time you improve the product.
Another time you strengthen distribution.
Another time you ignore the price change entirely.
Another time you introduce a premium offer.
Now the competitor has a harder problem.
They cannot confidently predict which response their move will trigger.
Strategic flexibility makes you harder to manipulate.
Law 17 Example: The Workplace
Imagine a colleague repeatedly gives you urgent work at the last minute.
You complain—but always complete it.
Your verbal reaction says:
“This isn’t acceptable.”
Your behavioral pattern says:
“This works.”
The colleague learns from the pattern.
Eventually, instead of automatically rescuing the situation, you say:
“I can’t take this today. We’ll need another solution.”
You haven’t behaved irrationally.
You’ve simply broken an exploitable expectation.
The pattern no longer guarantees the outcome.
Law 17 Example: Leadership
A leader shouldn’t make employees afraid of arbitrary punishment.
But a leader can avoid becoming strategically mechanical.
Suppose everyone knows exactly which proposal the leader will choose before a meeting begins.
People stop bringing alternatives.
They tailor information toward the expected decision.
A strong leader can remain consistent in standards while remaining genuinely open about solutions.
Employees know:
The decision will be rational.
But they cannot assume:
The decision has already been made.
That kind of uncertainty can improve thinking rather than create fear.
The Psychology Behind Law 17
Human beings constantly search for patterns.
Patterns reduce cognitive effort.
Once we believe we understand someone’s behavior, we create expectations:
“If I do X, they’ll do Y.”
Those expectations influence our decisions.
If the prediction repeatedly works, confidence increases.
That is useful in healthy relationships.
But in competitive situations, predictable behavior can become exploitable.
Breaking a pattern forces people to reconsider their model of you.
They must ask:
“What will they do this time?”
That uncertainty consumes attention.
It can also make people more cautious.
How to Apply Law 17 in Real Life
1. Identify Your Predictable Patterns
Ask:
What do people know I will almost always do?
Perhaps you always:
say yes
respond immediately
avoid confrontation
discount your price
explain yourself
rescue the project
make the first offer
Some patterns are strengths.
Others may have become vulnerabilities.
2. Preserve Principles, Vary Tactics
Don’t make your ethics unpredictable.
Make your strategic options broader.
You might consistently pursue the same objective while changing how you reach it.
That makes you flexible without making you unreliable.
3. Develop Real Alternatives
The strongest unpredictability comes from genuine options.
If you can:
accept the deal
reject it
delay it
choose another supplier
build internally
the other side cannot assume one response.
Options create uncertainty naturally.
You don’t need to manufacture it.
4. Occasionally Break an Exploitable Pattern
If someone has learned that you’ll always rescue them, don’t automatically rescue them.
If customers have learned that you’ll always discount, stop discounting automatically.
If someone expects an immediate emotional response, wait.
Breaking the pattern once can change future expectations.
5. Don’t Explain Every Decision in Advance
Constant explanation makes you easier to model.
You don’t need to announce every:
intention
threshold
fallback
negotiation limit
next move
This connects with Law 3 — Conceal Your Intentions.
Information you unnecessarily reveal can become information other people use.
6. Keep More Than One Credible Response Available
A chess player with one viable move is easy to constrain.
A person with several viable moves has flexibility.
Build alternatives before you need them.
Unpredictability is strongest when every option is credible.
7. Use Uncertainty Selectively
Don’t introduce unpredictability where reliability is essential.
Your customers should not wonder whether you’ll honor their purchase.
Your employees shouldn’t wonder whether they’ll be paid.
Your partner shouldn’t wonder whether you’ll respect fundamental commitments.
Use uncertainty around strategy, not basic trust.
When Law 17 Can Backfire
Too much unpredictability destroys confidence.
A business whose prices change inexplicably can frustrate customers.
A manager whose expectations change daily creates anxiety.
A partner who deliberately disappears to provoke insecurity damages trust.
A leader who makes surprising decisions merely to appear powerful eventually looks impulsive.
The distinction is critical:
Strategic unpredictability expands your options. Emotional unpredictability makes you unreliable.
The first can create leverage.
The second creates instability.
Law 17 at Work
At work, people quickly learn behavioral patterns.
Perhaps everyone knows:
“Give it to him late. He’ll complain, but he’ll still finish it.”
Or:
“She’ll never challenge the decision publicly.”
Or:
“He always accepts the first promotion package.”
Once a pattern becomes known, other people may begin incorporating it into their own decisions.
You don’t need to become erratic.
You may simply need to stop rewarding behavior that depends on your predictability.
Law 17 in Leadership
Leadership requires more predictability than many other applications of power.
Employees need stable:
expectations
standards
incentives
consequences
But strategic decisions don’t need to become formulaic.
A leader can surprise competitors while remaining dependable internally.
In fact, that is often the stronger combination:
stable inside, difficult to predict outside.
The organization knows what it stands for.
Competitors don’t know exactly what it will do next.
Law 17 in Business
Businesses become vulnerable when competitors can easily predict their response.
If every competitor promotion triggers your own promotion, they can influence your pricing.
If every new feature triggers immediate imitation, they can influence your roadmap.
If every criticism produces a public response, critics can command your attention.
A stronger organization has several possible responses and chooses according to circumstances.
That makes its strategy harder to manipulate.
Law 17 in Negotiation
Negotiation makes the value of unpredictability especially clear.
If the other side knows:
“They absolutely need this deal.”
your leverage decreases.
If they know:
“They will never walk away.”
your objections become less credible.
This is why genuine alternatives matter so much.
You don’t need theatrical unpredictability.
You need the ability to make decisions the other side cannot completely control.
This also connects with Law 16 — Use Absence to Increase Respect and Honor.
Sometimes withdrawing rather than continuing to negotiate changes the other side’s expectations.
Law 17 in Relationships
Personal relationships require caution.
Creating insecurity intentionally is not a healthy application of this Law.
Don’t manufacture jealousy.
Don’t unpredictably withdraw affection.
Don’t create fear to maintain someone’s attention.
A useful personal interpretation is much simpler:
Don’t become so mechanically accommodating that your boundaries stop meaning anything.
You can be dependable while still having independent preferences, decisions, and limits.
How Law 17 Connects to Other Laws
Law 3 — Conceal Your Intentions:
The less unnecessarily you reveal about your next move, the harder it becomes for others to prepare around it.
Law 4 — Always Say Less Than Necessary:
Overexplaining your thinking can expose patterns and limits that others can later exploit.
Law 8 — Make Other People Come to You:
Being willing to stop pursuing an outcome creates uncertainty about whether you will continue participating.
Law 16 — Use Absence to Increase Respect and Honor:
Strategic withdrawal can interrupt expectations and force others to reconsider how available you really are.
Together, these Laws create a useful principle:
Protect information → maintain alternatives → avoid exploitable patterns → remain difficult to control.
Law 17 in One Sentence
Cultivate an Air of Unpredictability means remaining strategically flexible enough that other people cannot confidently anticipate and exploit every response you will make.
The objective isn’t chaos.
It’s optionality.
Be dependable where trust matters and unpredictable where predictability would make you vulnerable.
Train Law 17 Until You Recognize the Situation
A supplier knows you always accept after negotiating long enough.
Do you repeat the pattern or demonstrate that walking away is possible?
A colleague knows you’ll always rescue a late project.
Does helping again solve the problem—or reinforce it?
A competitor expects you to match every price cut.
Do you respond as expected or choose a different strategic lever?
Someone provokes you because they know exactly how you’ll react.
Do you give them the response they anticipated?
These situations require judgment about patterns, alternatives, information, reliability, and timing.

Instead of simply memorizing Law 17, you practice situations where predictability, restraint, alternatives, and unexpected moves can produce very different outcomes.
Final Thought
Predictability makes life easier.
It also makes strategy easier—for the other side.
Don’t confuse reliability with being mechanically easy to anticipate.
Keep your commitments.
Maintain your principles.
But preserve enough flexibility that nobody can confidently decide your next move for you.
Let people trust your character.
Don’t let them completely map your strategy.
