Thinking outside the box (also thinking out of the box or thinking beyond the box) is a metaphor that means to think differently, unconventionally, or from a new perspective. This phrase often refers to novel or creative thinking. To think outside the box is to look farther and to try not thinking of the obvious things, but to try thinking beyond them. The term is thought to derive from management consultants in the 1970s and 1980s challenging their clients to solve the “nine dots” puzzle, whose solution requires some lateral thinking.
