lateral thinking
Lateral thinking is a method of generating ideas without being bound by established theories or concepts in order to solve problems. [It was first proposed by Edward Debono around 1967.
De Bono refers to conventional logical and analytical thinking as Vertical thinking, which is effective for deepening logic, but difficult to generate novel ideas. In contrast, horizontal thinking is a method that generates intuitive ideas by looking at things from a variety of perspectives.
