Lateral Thinking, Made Practical
What is lateral thinking and how do you use it to solve problems?
Lateral thinking, coined by Edward de Bono, is a set of deliberate techniques for disrupting habitual thought patterns so that a problem can be approached from an unexpected angle. Unlike vertical (logical) thinking, which deepens the current line of reasoning, lateral thinking deliberately abandons it to find a new entry point. Evidence for specific techniques is largely observational and practitioner-reported; the underlying cognitive principle — that breaking pattern-lock enables novel solutions — has support in creativity research.
Edward de Bono introduced lateral thinking in the late 1960s as a direct counter to the limitations of purely logical, sequential reasoning. His core insight: the brain is a pattern-matching organ, and most problems that resist standard analysis do so because the thinker is trapped inside a pattern that the problem created. Lateral thinking techniques are designed not to find the right path, but to interrupt the current path long enough for a different one to become visible. Below are the core practices, each with the mechanism that makes it work and an honest read on the evidence.
Practices
- Random entry: force a random stimulus into the problem
- Provocation (PO): make a deliberately absurd statement to escape the pattern
- Concept fan: map the solution space before picking a direction
- Challenge: systematically question why things are done the way they are
- Systematic alternatives: generate three more explanations before deciding
- Reverse brainstorm: solve the opposite problem first
- Use a stepping-stone idea: an intermediate impossible idea
Random entry: force a random stimulus into the problem
Open a dictionary to a random word, then connect it to the problem — the forced association breaks the current pattern lock.
Provocation (PO): make a deliberately absurd statement to escape the pattern
Prefix an impossible or absurd idea with "PO" to signal it is a provocation, not a proposal — then follow it to see what it unlocks.
Concept fan: map the solution space before picking a direction
Expand from specific solutions to the broader concept behind them, then generate alternatives at the concept level.
Challenge: systematically question why things are done the way they are
Ask "Why must this be this way?" for each element of the problem — not to be contrarian, but to find which constraints are real.
Systematic alternatives: generate three more explanations before deciding
Force yourself to generate at least three alternative explanations or interpretations before committing to the first plausible one.
Reverse brainstorm: solve the opposite problem first
Ask "How would we guarantee the worst possible outcome?" — then invert every answer.
Use a stepping-stone idea: an intermediate impossible idea
Generate a deliberately impractical intermediate idea to use as a bridge to a practical one you could not have reached directly.
