Lateral thinking helps solve problems by looking at them in new ways, questioning assumptions, and trying approaches that aren’t obvious or based on standard logic.
Edward de Bono created the term ‘lateral thinking’ because traditional thinking is good at developing existing ideas but often struggles to create new ones.
He believed our usual ways of thinking are efficient but can also hold us back. We tend to notice only what we expect. Lateral thinking gives us ways to break out of these habits.
The idea behind lateral thinking
De Bono thought tough problems stick around because people keep using the same approach. Lateral thinking helps break that pattern.
Instead of only asking, “What is the logical next step?” you can also ask yourself:
- What if the opposite were true?
- What if I defined the problem differently?
- What ideas seem wrong but might contain something useful?
The main idea is simple:
- Vertical thinking moves logically from one justified step to the next.
- Lateral thinking encourages you to look at things from a different angle and find new ways to begin.
He created lateral thinking to fill a gap. Traditional logic is good for evaluating and improving ideas, but not for generating them. People often stick to familiar methods, even if they don’t work well. De Bono believed creativity can be learned, not just something you’re born with. Lateral thinking tries to make creativity a regular process, not just something that happens by chance.
How lateral thinking works
Lateral thinking shakes up our usual ways of thinking and prompts us to consider ideas we might otherwise ignore.
A simple, step-by-step process starts with:
- Clearly state the problem. Example: “How do we reduce traffic congestion?”
- Identify hidden assumptions. Example: “More cars mean we need more roads.” That assumption might be true, but it can limit our ideas.
- Use a deliberate thinking technique: 1.
- Reverse the assumption.
- Introduce a random stimulus.
- Generate a provocative statement.
- Split Hold off on judging ideas right away. The goal isn’t to be correct immediately, but to explore new possibilities.to explore new possibilities.
- Extract value from unusual ideas. Even a strange idea may contain a practical principle.
- Turn promising ideas into practical solutions. Lateral thinking helps you come up with options, while traditional thinking helps you test and use them. Lateral thinking is most effective when combined with careful analysis.
Two lateral thinking techniques
1. Reversal: Reversal means taking a normal assumption or standard way of doing things and turning it around.
Example:
- Normal assumption: “Restaurants need to speed up table service.”
- Reversal: “What if restaurants made customers spend more time there on purpose?”
That reversed idea might lead to:
- lounge-style seating
- social dining experiences
- profitable desserts and drinks
- a restaurant focused on atmosphere instead of quick turnover. Reversal helps reveal hidden assumptions, but it’s just a starting point, not the final answer.
2. Random entry: Random entry uses a random word, image, or stimulus to force a fresh connection.
Example: Problem: “How can a school improve student engagement?” Random word: garden
This might lead to:
- learning spaces outdoors
- student ownership of projects that grow over time
- peer mentoring arranged like an ecosystem
- Subjects could be connected by ideas such as “cultivation” or long-term growth. Most random connections won’t lead to much, but a few can spark great ideas.
Examples of success:
Lateral thinking can be seen in results, even though it’s sometimes hard to prove exactly when it was used.
1. Self-service business models
Instead of assuming service must always be delivered directly by staff, businesses asked: What if customers do part of the process themselves?
That kind of reframing contributed to the development of models such as ATM self-checkout systems. These successes came from questioning the idea that more convenience always means hiring more staff.
2. Low-cost airlines
Traditional airline thinking emphasized included services and full-service travel. A lateral shift asked: What if customers mainly want safe, cheap transport rather than bundled extras?
That reframing helped support the low-cost airline model:
- no-frills service
- faster aircraft turnaround
- direct booking
- optional add-ons. By looking at things differently, airlines redefined what customers actually pay for.
Problems and limitations of lateral thinking
Lateral thinking has limitations.
- It can generate impractical ideas
- It may feel inefficient
- It depends on follow-through
- It may be resisted in structured organizations
- It is not ideal for every problem
- It can be mistaken for just coming up with any wild idea.
Lateral thinking isn’t random. If used improperly, it turns into unfocused brainstorming.
Conclusion
Lateral thinking is a structured approach to breaking habitual thought patterns, enabling the generation of new and useful ideas, especially when conventional logical approaches are at a standstill.
Here is a summary:
- Concept: solve problems by reframing them and breaking assumptions
- Why: to complement standard logical thinking with deliberate idea-generation methods
- How it works: disrupt patterns, suspend early judgment, explore alternatives, then evaluate.
- Successes: innovations such as self-service systems, no-frills models, and convenience-based redesigns
- Problems: can be inefficient, impractical. Here’s an easy way to remember: vertical thinking finds the fastest route, while lateral thinking gives you a new map to discover hidden opportunities and unexplored treasures.
