Someone might think: "Ropes made of nylon are strong, to be sure, but with hemp ropes you can make use of natural resources. The hemp ropes may not be as strong as the nylon, but they'll eventually return to the earth without causing any pollution." These are examples of thinking outside the box.
另一例是，塑膠做的繩子很強壯，但利用大自然素材所做的繩子，雖然比塑膠繩脆弱，但最後還是回歸大地，對環境不會造成污染，這都是一種逆向思考。
