Deception

Strategic deception

“If you conceal your intentions and capabilities, you lead your opponent to commit their forces in the wrong place at the wrong time.”

Every opponent aligns their forces with the picture they have formed of you.

In short

If you conceal your intentions and capabilities, you lead your opponent to commit their forces in the wrong place at the wrong time.

What it’s about: Every opponent aligns their forces with the picture they have formed of you. Deception changes that picture: they think you are weaker than you are, or they expect you somewhere else. The goal is a wrong decision, not merely a wrong impression. They defend the wrong spot or commit their reserves too early.

In depth

The principle in detail

Three steps through the principle: grasp it, place it, put it to work. Open each topic on its own.

The core messageCore statement and 3 clarifications
In essence

If you change your opponent’s picture, you change their decisions. That way you shift the balance of forces at the decisive point without having more yourself.

It does not say
That deception is allowed toward people whose trust you need. There it is not strategy but a breach of trust, often fraud.
It does not say
That the ruse is already the victory. It creates an advantage that you still have to exploit afterward.
It also says
Every deception has an expiration date. The longer it has to hold, the more expensive and risky it becomes.
The explanationThe principle comes from war and applies only where there is genuine opposition.
  • The principle comes from war and applies only where there is genuine opposition.
  • Holding back in competition is legitimate.
  • But if you deceive employees, customers, investors or your own family, you may win a moment and lose the trust on which everything else rests.
The question

Who is really your opponent here, and what picture do they have of you?

The signs3 signs when you heed it · 3 when you overlook it
When you heed it
  • You hold back plans from competitors until they are final.
  • In negotiations, you do not reveal your limit.
  • With your team and your customers, you are straight about how things stand.
When you overlook it
  • You announce every step, and the competition adjusts to it.
  • Or you carry the ruse over into relationships and describe the situation to your team as better than it is.
  • After that, no one quite believes you anymore.

From the first chapter of “The Art of War,” attributed to Sun Tzu (Sun Wu, 6th or 5th century BC); known in Europe through the translations by Jean Joseph Marie Amiot (1772) and Lionel Giles (1910). Supplemented by Barton Whaley’s study “Stratagem” (1969) and the objection raised by Carl von Clausewitz in “On War” (1832).

  1. 6th/5th c. BCtrans. 1910
    Classic
    Sun Tzu

    Chapter 1: “All warfare is based on deception”; when able to attack, you must seem unable; when near, far away.

  2. 1832
    Classic
    Carl von Clausewitz

    “On War” (in German), Book III, Chapter 10, “Cunning”: there is little room for cunning in strategy; feints tie up time and forces; cunning is more accessible to the weaker side.

  3. 1969
    Case study
    Barton Whaley

    “Stratagem: Deception and Surprise in War”: more than 100 cases from military history; surprise and deliberate deception are closely linked.

Where the research reaches its limits
  • The principle applies only toward genuine opponents.
  • Toward partners, customers and employees, deception is not strategy but a breach of trust.
  • Carl von Clausewitz considers large-scale deceptions costly because they tie up forces.
  • The sources do not examine whether deception works in business competition the way it does in war.
Read more: what research shows

The principle is a classic, not a measured regularity. In “The Art of War,” attributed to Sun Tzu, the first chapter says that all warfare is based on deception: when able to attack, you must seem unable; when near, you must seem far away. In his study “Stratagem,” Barton Whaley compared more than 100 cases from military history and described a close link between deliberate deception and surprise. Carl von Clausewitz counters: cunning, he argues, has little room in strategy. Feints cost time and forces, and it is dangerous to use substantial forces for a long time merely for show. Cunning, he says, is more accessible to the weaker side. Psychology explains why deception succeeds so often: people look for confirmation of what they expect. The sources do not name a specific study on this.

The action steps5 action steps: Distinguish clearly who is an opponent in this situation and who is a partner.
  1. Distinguish clearly who is an opponent in this situation and who is a partner. Deception is an option only toward opponents, and even there only within the bounds of law and decency.

  2. Ask yourself what picture the competition has of you and what decisions it derives from that picture.

  3. Hold back what others do not need to know: your timetable, your limit, your next step. Holding back is usually enough; you will rarely need active misrepresentation.
  4. Count the cost: How much strength does a deception tie up, and how long does it have to hold?
  5. Check yourself from the other side too: Which clues do you believe because they fit your expectations? Ask someone for a dissenting view.
The reflection questions3 questions: Who in your world is really an opponent, and toward whom do you need trust?
  1. Who in your world is really an opponent, and toward whom do you need trust?
  2. What picture does your most important competitor have of you, and what do they do because of it?
  3. Which clue did you last believe only because it fit your expectations?

Take your time with one question. Write down your answer – or talk it over with someone you trust.

The principle in practice

From the different spheres of society.

Government

Operation Mincemeat and Deception

In the spring of 1943, British intelligence officers let a corpse carrying forged letters drift off the Spanish coast. The German leadership believes the papers, reinforces Greece and Sardinia and expects the Allied landing in the wrong place.

Deception
Faith

Japan’s Hidden Christians and Deception

Starting in 1614, Christianity is banned in Japan. For more than two centuries, believers in the Nagasaki region preserve their faith by disguising it as Buddhism, venerating Mary as Kannon and making their prayers sound like Buddhist chants.

Deception

Elizabeth Holmes, Theranos and Deception

Theranos promises comprehensive blood tests from a few drops and is at times valued at $9 billion to $10 billion. But the technology cannot do what is claimed. In 2015, The Wall Street Journal uncovers the deception; in 2022, Elizabeth Holmes is convicted of defrauding investors.

Deception
Business

Movie: The Sting

In “The Sting” (1973), two con men in 1930s Chicago set up an entire fake betting parlor to ruin a gangster boss. The film shows that a big deception is made up of many small ones, and that in the end the person deceived must not even notice that he has been deceived.
