Creativity is one of the most misunderstood reasoning skills. The popular framing treats it as a trait you either have or don't, but the research keeps showing it's a teachable discipline grounded in specific techniques — separately measurable dimensions like how many ideas you generate and how many different categories they span, plus named methods like brainstorming, lateral thinking, and biomimicry that anyone can learn.
A few findings are worth carrying: generating and narrowing are both necessary, and output suffers when either is skipped; holding judgment during the generating phase sharply improves it; constraints, counterintuitively, often increase creative output by focusing the search; and borrowing structure from a distant field is the strongest single predictor of breakthrough. The stubborn obstacle is functional fixedness — seeing an object only as its usual self — which is why deliberate techniques exist to break it. The same moves work for product design, scientific hypotheses, business strategy, and everyday problems, because they don't care what the material is.
