Lateral Thinking

IDEA 1
Lateral thinking escapes old patterns
De Bono argues that the mind naturally forms patterns, which help us think quickly but also trap us in familiar ways. Lateral thinking is a set of deliberate techniques for escaping these patterns to find new ideas.
IDEA 2
Vertical thinking is not enough
De Bono contrasts vertical thinking, which moves step by step logically, with lateral thinking, which jumps sideways to new possibilities. Both are useful, but lateral thinking generates new ideas. Good thinkers need both.
IDEA 3
Question assumptions
De Bono encourages challenging assumptions, asking why things are done a certain way. Many assumptions are unnecessary. Asking why a thing must be done in a given way can reveal that a better way was open all along.

IDEA 1
Think in parallel, not in conflict
De Bono argues that meetings often become arguments, with people attacking each other's ideas. His Six Thinking Hats method lets a group think in parallel, all looking at a problem from the same angle at the same time.
IDEA 2
White hat looks at facts
The white hat focuses on information: what facts do we have, and what do we need? It keeps discussion grounded. Wearing this hat means everyone sticks to what is known and what is missing, instead of arguing opinions at this stage.
IDEA 3
Red hat allows feelings
The red hat lets people express emotions and intuitions without explanation. Feelings are treated as valid information. This hat lets a person say how they feel about an idea in a few words, without having to defend it with reasons.
