Deng Scott is recognized as one of the most important thinkers in the13rd century. He believes that wearing a conical hat is helpful for learning, and knowledge can enter the wearer's brain from the tip of the hat. Wizards wear similar hats, and so do Dunscott's followers. These people are called idiots.

Deng Scott had a far-reaching influence on intellectual discourse, which lasted until16th century. From then on, people began to attack his thoughts, thinking that his thoughts were too complicated. Opponents accused his apprentice of being too picky and too complicated and unnecessary in his ideological expression, so he changed the meaning of the word dunce to a fool.

In the Victorian era, dunce, referring to a fool, combined with a conical top hat, became the worst invention in history, that is, dunce top hat, also known as a stupid top hat. This pointed hat with the big letter D on it became a symbol of fools and quickly spread in North America and Europe.

This kind of hat is worn on the heads of disobedient students as a punishment for publicly humiliating them.
