Why a hammer must be a hammer

  What is the typical function of a hammer? Knock something. Are there any more? I can’t remember it for a while, because your mind is fixed on “the hammer is used to hit things”.
  Psychologist Norman Meyer’s “rope experiment” almost drove the participants crazy. Participants enter a room with two ropes hanging from two places on the ceiling. Their task is to tie the two ropes together. Unfortunately, the distance between the two ropes is too far, and the participant cannot reach them at the same time.
  When the participants were solving problems, their thinking was solidified, and they did not think of using other tools in the room, such as pliers. If you regard the pliers as a pendulum, it becomes a key prop to complete the task.
  Tie the pliers to a rope and let it sway like a pendulum. Hold the other rope with your hands and wait aside. When the “pendulum” swings near you, pull the pliers so that you can tie the two ropes together smoothly. Up.
  The key to the problem lies in the way the information is processed. Among them, IQ plays a much smaller role than the quality of information processing.
  A good thinker will notice two things: he has a comprehensive and clear vision of the situation and problems in his head, and he has simple and clear creative thinking strategies.
  When I was working at the University of Cologne, I heard a lecture by a visiting professor. The projector is installed, but it has not been tested. During the demonstration, people can clearly see: the projector is placed too low, the audience can only see half of the content on the screen, and the other half is blocked. The senior students quickly took remedial measures, and they found a book under the projector. However, the book is too thick. Solution: You must change to a thinner book. When everyone tried their best to find the thin book, a female student in the lower grade came over and opened the thick book in the middle. It’s good now, the height is right.
