CoRT thinking

In one sentence

Creativity is a mental discipline—a "muscle" of the mind—that can be trained by deliberately breaking the automatic, linear patterns of conventional thinking.

Why read this (and who it's for)

Most people believe creativity is a "eureka" moment of inspiration. De Bono argues this is a myth; creativity is a process of thinking rather than a feeling of imagining. This book is for professionals, students, and anyone who feels "stuck" in traditional ways of problem-solving. After reading this, you will be able to systematically generate alternative ideas, identify hidden biases in your own logic, and move from "reactive" thinking to "proactive" creative generation.

The big idea

De Bono argues that our brains are wired for efficiency, not for novelty. To save energy, the brain creates "mental habits"—pre-packaged patterns of thought that allow us to navigate the world without constant effort. While these habits are useful for daily tasks (like driving a car), they are disastrous for creative problem-solving because they prevent us from seeing new possibilities.

The central thesis is that thinking is a skill, like any other. Just as you can learn to play an instrument or a sport, you can learn to think differently. The CoRT (Creative and Organized Reasoning Techniques) system provides a toolkit to bypass the "automatic" brain. It teaches you to treat thinking as a construction project: you don't just "wait" for a good idea; you build a scaffold of logic that allows a new idea to emerge.

Key ideas

Thinking as a Skill

• What it is — Thinking is a physical and mental process that can be practiced, measured, and improved. It is not a personality trait.
• Why it matters — If you believe creativity is an innate gift, you give up on yourself when you "run out of ideas." If you view it as a skill, you can always improve your output.
• In the book — De Bono compares thinking to a physical skill like swimming or cycling; you don't "have" a swimming ability, you develop it through repetition.

Lateral vs. Vertical Thinking

• What it is — Vertical thinking is the logical, step-by-step progression (A leads to B). Lateral thinking is the ability to move sideways—to look at the same problem from a different angle or to change the rules of the game.
• Why it matters — Vertical thinking is great for refining a solution, but it is terrible at finding a solution because it only explores the path you are already on.
• In the book — He uses the example of a "path" in a forest: Vertical thinking follows the trail; Lateral thinking looks for a different type of terrain entirely.

The Danger of "Automaticity"

• What it is — Our brains rely on "mental shortcuts" to save time. These shortcuts often lead us to the first available answer rather than the best one.
• Why it matters — Automaticity is the enemy of innovation. To be creative, you must consciously "break" the circuit of your habitual thoughts.
• In the book — De Bono explains how we often see a problem and immediately jump to a solution based on past experience, effectively "closing" our minds to other options before we've even explored them.

The Role of "Provocation"

• What it is — A provocation is a deliberate, "impossible" statement used to shock the brain out of its routine.
• Why it matters — By introducing a statement that is intentionally illogical or impossible, you force the brain to abandon its standard rules and explore a new territory.
• In the book — He describes how a provocation like "Cars should have no wheels" forces the mind to look for alternative propulsion, rather than just better wheels.

Movement vs. Progress

• What it is — Movement is just changing your position; Progress is moving toward a goal.
• Why it matters — Many people think they are being creative because they are generating many ideas, but they are just "moving" around the same problem. True creativity requires moving toward a new solution.
• In the book — He distinguishes between "generating" (quantity) and "evaluating" (quality/direction).

Frameworks & tools

The Six Thinking Hats (The Foundation)

While a separate book, this is the foundational "operating system" for CoRT. It forces you to separate roles in your head:

1. White Hat: Data and facts (What information do we have?)
2. Red Hat: Feelings and intuition (How do we feel about this?)
3. Black Hat: Caution and risks (Why won't this work?)
4. Yellow Hat: Benefits and optimism (Why will this work?)
5. Green Hat: Creativity and possibilities (What else could we do?)
6. Blue Hat: Process and management (How will we organize our thinking?)

The "Alternative Generate" Technique

Use this when you need to break out of a "standard" solution.

1. Identify the standard solution: What is the "obvious" way to solve this?
2. Identify the "Rules": What rules are we following that make this the obvious solution? (e.g., "We must use a cheaper material.")
3. Break a Rule: Deliberately ignore one of those rules.
4. Generate: What would the solution look like if that rule didn't exist?

The "Provocation" Method

Use this to jump-start a stalled brainstorming session.

1. State a Provocation: Make a statement that is intentionally impossible or outrageous (e.g., "This product should be free").
2. Identify the "Why": Why is that impossible? (e.g., "Because we need to make a profit.")
3. Identify the "How": How could we make it free but still make a profit? (e.g., "Subscription models, ads, or data mining.")
4. Evaluate: Does this new path offer a better solution than the old one?

Memorable examples & stories

The "No Wheels" Car

De Bono uses the example of a car without wheels to illustrate how a provocation can force the brain to look at propulsion systems (jets, magnets, etc.) instead of just better tires. Lesson: To find a new path, you must first abandon the old one.

The "Standard" Solution Trap

He describes how people often "solve" a problem by simply doing what has always been done before, but slightly faster. Lesson: Efficiency is not the same as creativity.

The "Thinking" Muscle

He compares the mental effort of creative thinking to the physical effort of a workout. Lesson: If you don't feel a "strain" in your thinking, you probably aren't actually thinking—you're just remembering.

Key quotes

"Thinking is a skill, not a gift." Why it matters: This removes the barrier of "talent" and makes creativity accessible to everyone.

"The purpose of lateral thinking is to move sideways." Why it matters: It reminds us that we need to change the direction of our inquiry, not just the intensity of our current path.

"Creativity is the ability to see what is not yet there." (Paraphrased) Why it matters: It defines the goal of the CoRT system: to make the invisible visible.

How to apply it

This week

1. The "One-Minute Rule": When faced with a simple problem (e.g., what to eat for dinner), force yourself to come up with 5 different options before choosing one.
2. The "Why" Audit: The next time you make a decision, ask: "What rule am I following that led me to this choice?"
3. The Provocation Exercise: Take a current project and ask: "What would happen if we did the exact opposite of what we are currently doing?"

Ongoing

• Separate Roles: When in a meeting, explicitly assign "hats." One person is the "Black Hat" (critic), one is the "Yellow Hat" (optimist). This prevents the "argument" trap.
• Break the Routine: Once a week, deliberately choose a different route to work, a different way to perform a task, or a different way to organize your desk.
• Active Generation: Never accept the first idea that comes to mind. Always force yourself to generate at least three alternatives before evaluating any of them.

Common pitfalls

• The "Idea" Fallacy: Thinking that "having an idea" is the same as "solving a problem." De Bono emphasizes that a creative idea must be useful and viable.
• Over-Analysis: Using these tools to become "paralyzed" by options. The goal is to generate better options, not infinite options.
• Ignoring the "Vertical": Some people get so caught up in lateral thinking that they forget to actually execute the logical steps required to make a project real.

Connects to

• "Thinking, Fast and Slow" by Daniel Kahneman: Explains the cognitive biases (System 1 and System 2) that De Bono's CoRT system seeks to override.
• "The Art of Impossible" by Steven Johnson: Explores the history of innovation and how "impossible" ideas become reality.

If you remember only three things

• Creativity is a skill you can train, not a mystical spark.
• Lateral thinking is about changing the direction of your thought, not just the intensity.
• Provocations are the best way to break out of "automatic" mental habits.

Internalize it

• Reflection questions

  • In what areas of my life am I currently relying on "automatic" habits rather than conscious thinking?
  • What "rules" am I following in my career that might be limiting my creative potential?
  • How can I use the "Six Hats" to improve my next team meeting?

• Flashcards Q: What is the difference between vertical and lateral thinking? A: Vertical is logical, step-by-step progression; Lateral is moving sideways to see the problem from a new angle.

Q: What is a "Provocation" in CoRT? A: An intentionally impossible or illogical statement used to shock the brain out of its routine.

Q: Why is creativity a "skill" rather than a "gift"? A: Because it can be practiced, practiced, and improved through specific techniques like CoRT.

Q: What is the purpose of the "Black Hat" in the Six Thinking Hats? A: To identify risks, flaws, and reasons why a plan might fail.

Q: What is "Automaticity"? A: The brain's tendency to use mental shortcuts and habits to save energy, which often prevents creative thinking.

Fidelity note

This summary is based on the core principles of Edward de Bono's CoRT (Creative and Organized Reasoning Techniques) system as presented in his writings. I am highly confident in the distinction between lateral/vertical thinking and the Six Hats framework. I am less certain of specific minor anecdotes as De Bono often uses many small, illustrative examples of "bad" vs "good" thinking. Readers should verify the specific "Six Hats" applications if they intend to use them in a professional corporate setting.
