What is Lateral Thinking?

Lateral thinking (horizontal thinking) is a form of ideation where designers approach problems by using reasoning that is disruptive or not immediately obvious. They use indirect and creative methods to think outside the box and see problems from radically new angles, gaining insights to help find innovative solutions.

“You cannot dig a hole in a different place by digging the same hole deeper.”

— Dr. Edward de Bono, Brain-training pioneer who devised lateral thinking

Lateral Thinking helps Break Out of the Box

Many problems (e.g., mathematical ones) require the vertical, analytical, step-by-step approach we’re so familiar with. Called linear thinking, it’s based on logic, existing solutions and experience: You know where to start and what to do to reach a solution, like following a recipe. However, many design problems—particularly, wicked problems—are too complex for this critical path of reasoning. They may have several potential solutions. Also, they won’t offer clues; unless we realize our way of thinking is usually locked into a tight space and we need a completely different approach.

That’s where lateral thinking comes in – essentially thinking outside the box. “The box” refers to the apparent constraints of the design space and our limited perspective from habitually meeting problems head-on and linearly. Designers often don’t realize what their limitations are when considering problems – hence why lateral thinking is invaluable in (e.g.) the design thinking process. Rather than be trapped by logic and assumptions, you learn to stand back and use your imagination to see the big picture when you:

  • Focus on overlooked aspects of a situation/problem.

  • Challenge assumptions – to break free from traditional ways of understanding a problem/concept/solution.

  • Seek alternatives – not just alternative potential solutions, but alternative ways of thinking about problems.

When you do this, you tap into disruptive thinking and can turn an existing paradigm on its head. Notable examples include:

  • The mobile defibrillator and mobile coronary care – Instead of trying to resuscitate heart-attack victims once they’re in hospital, treat them at the scene.

  • Uber – Instead of investing in a fleet of taxicabs, have drivers use their own cars.

Rather than focus on channeling more resources into established solutions to improve them, these innovators assessed their problems creatively and uncovered game-changing (and life-changing) insights.

How to Get Fresh Perspectives with Lateral Thinking 

For optimal results, use lateral thinking early in the divergent stages of ideation. You want to reframe the problem and:

  1. Understand what’s constraining you and why.

  2. Find new strategies to solutions and places/angles to start exploring.

  3. Find the apparent edges of your design space and push beyond them – to reveal the bigger picture.

You can use various methods. A main approach is provocations: namely, to make deliberately false statements about an aspect of the problem/situation. This could be to question the norms through contradiction, distortion, reversal (i.e., of assumptions), wishful thinking or escapism, for example:

Here, we see the norm of conventional schooling challenged and some unpredictable (and even outrageous) notions to trigger our thinking. Our example showcases this method:

  • Bad Ideas – You think up as many bad or crazy ideas as possible, but these might have potentially good aspects (e.g., helping children specialize in desired subjects earlier). You also establish why bad aspects are bad (e.g., inserting biochips would be a gross violation of human rights).

Other helpful methods include:

  1. Random Metaphors

    • Randomly pick an item near you or word from a dictionary and write down as many aspects/associations about it as possible. E.g., “Exhibition” – “visitors walk around enjoying paintings”; “learn about cultures”; “pleasant environment”.

    • Pretend some genius in your field told you this item/word is a good metaphor for your project. E.g., you can organize information, tips and images for your travel-related app to also act like an art/museum exhibition, so anyone can enjoy an interesting tour of a given location.

    • Use the metaphors you think of to improve your design/product. E.g., you create a captivating app which virtual tourists can enjoy with (e.g.) virtual reality features.

  2. SCAMPER – To help generate ideas for new solutions, ask 7 different types of questions to help understand how you might innovate and improve existing products, services, concepts, etc. SCAMPER is remarkably easy to learn and efficient in ideation sessions.

  3. Six Thinking Hats – To reach for alternative viewpoints, you examine problems from 6 perspectives, one at a time (e.g., white hat = focusing on available data; black hat = focusing on potentially negative outcomes).

Overall, it’s important to stay aware of where ideation sessions are going. You may need to pause to redirect the group’s thinking or introduce a new trigger/provocation to help the creative process. Later, you use convergent thinking to isolate optimal solutions.

Imagine a person who is generally optimistic. Using the ' black hat ' approach, they could try looking at things negatively. This might help them find new, innovative solutions that they wouldn't have thought of. They can gain a better understanding of the situation by changing their perspective.

What are the four techniques of lateral thinking?

The four lateral thinking techniques are:

  1. Provocation: This involves disrupting conventional thinking patterns with unusual ideas.

  2. Challenge: The challenge is about questioning the status quo. It’s about looking at things as if they might be wrong, even if they seem right. This approach encourages deeper analysis and alternative viewpoints.

  3. Random Entry: This technique generates new ideas using a random word or idea as a starting point. It creates connections that may not be immediately noticeable.

  4. Alternatives: It focuses on shifting thinking patterns by exploring various directions and possibilities.

What is lateral vs linear thinking?

Lateral thinking and linear thinking are two distinct approaches to problem-solving. Linear thinking is sequential and logical. It follows a straight, step-by-step path that relies on data and analysis. It focuses on following the standard path of reasoning going along, as Alan Dix describes it.

Lateral thinking is non-linear. It involves creativity and looking at problems from various angles. It’s about challenging assumptions and exploring unconventional solutions. 

Linear thinking concentrates on details and processes. Whereas lateral thinking emphasizes brainstorming and producing innovative ideas. Both are valuable, but they approach problems from different perspectives.

Is lateral thinking a skill?

Yes, lateral thinking is a valuable skill. It's a problem-solving approach that stresses creative thinking. Unlike traditional linear thinking, it's about exploring diverse ideas. You can hone this skill through practice, challenging assumptions, making unexpected connections, and approaching problems from fresh angles. 

People skilled in lateral thinking are often adept at generating innovative solutions. Many fields, especially those requiring innovation and creativity, value this skill.

Are lateral thinkers intelligent?

Lateral thinking often aligns with intelligence distinct from traditional measures like IQ. Intelligence manifests in various forms, and lateral thinking showcases creative, problem-solving intelligence. Lateral thinkers view things from unique perspectives. They create innovative ideas and link unrelated concepts. This ability marks an essential aspect of creative intelligence. 

This video discusses problem redefinition and negotiation in real-world scenarios. Traditional intelligence focuses on finding a single right solution using given information. But lateral thinking is like solving real-world problems. This approach holds significant value in fields that demand innovation and creative problem-solving. Here, Professor Alan Dix discusses

Is lateral thinking logical?

While different from traditional logical thinking, lateral thinking has its logic. It’s not illogical or random. Instead, it follows a distinct reasoning that prioritizes creativity and innovation. Traditional logic is linear and sequential. It focuses on reaching conclusions based on existing knowledge and facts. 

Lateral thinking involves looking at problems from new angles and making unexpected connections. Lateral thinking is a creative way of problem-solving. It can help you find unique and practical solutions. Lateral thinking is a powerful tool when conventional logic doesn't work. Check out this video to learn about different types of creativity and what can get in the way of being creative.

Is lateral thinking the same as brainstorming?

Lateral thinking and brainstorming are similar yet different. Lateral thinking helps solve problems using creative and unconventional approaches. It breaks away from traditional methods.

Brainstorming is a group activity where people contribute ideas without judgment to solve a problem. It generates creative solutions.

Lateral thinking can be a solitary or group activity and it focuses on thinking differently. It's a specific approach to problem-solving that emphasizes creativity.

Why is lateral thinking important?

Lateral thinking is crucial because it fosters creativity and innovation. It allows you to explore new ideas and solutions that conventional, linear thinking might not reveal. Lateral thinking helps adapt to new challenges and situations. It encourages looking at problems from multiple perspectives. This leads to more comprehensive and sometimes unexpected solutions. This type of thinking is crucial in innovative fields like business, technology, and design. 

Lateral thinking breaks from traditional thought patterns and contributes to advancements and breakthroughs. It enhances problem-solving skills and promotes a more dynamic approach to challenges.

Is lateral thinking divergent thinking?

Yes, lateral thinking is a form of divergent thinking. Divergent thinking is about spontaneously generating diverse ideas or solutions to a problem. Lateral thinking, a term coined by Edward de Bono, is a specific kind of divergent thinking. It looks at problems from new and unusual angles and seeks innovative solutions outside conventions. 

Divergent thinking is a broader concept encompassing various methods of generating creative ideas. Lateral thinking focuses more on breaking conventional patterns and thinking beyond the norm. Both are key in creative processes, encouraging broad exploration of possibilities.
