On The Three-door Problem From The Viewpoints Of Cognitive Logic

With the discussion of three-door problem, in this paper it is intended to explore the reasons for the choosers to have the different viewpoints of this problem, and then to grasp the nature of three-door problem and its disagreement reasons. The choice of actors probability judgments and its strategy are systematically explored here.In the first part, the origin of three-door problem and its research status are mainly discussed. Three-door problem (namely, Monty Hall problem) was firstly found in American magazine Parade in1990s. The magazine columnist Marilyn thought that it is beneficial to get the car by changing the choice, and it is explained for three times, hoping to persuade the reader to support this view. But most people did not agree with this statement, so that this problem raised the global heated debates. And the various scholars in different fields are trying to support their own views through their elaboration Many scholars mostly study the three-door problem from the perspective of psychology and mathematics. However, by using logical methods of thinking to focus on it, we can understand the three-door problem better than before. Logical methods of thinking play an important role in understanding this problem.In the second part, the predicaments of three-door problem and its essence are systematically investigated. There are three main predicaments of it, such as information vacancy, the logic rationality of subject and the individuals’inclinations. As the default of premise information, the different premise information will bring different results. The rationality is not the same as the information processing of different subjects with their individual inclinations more or less. So many factors bring us into the three-door dilemma. The essence of three-door dilemma is the subjects’cognitive process of information. Different subjects will produce different conclusions in the cognitive process of information.In the third part, the approaches or strategies of three-door problem are considered. The individual inclinations will be rationally optimized, and the cognitive information of individual inclinations, subjective assignment and subject system of preferences are adjusted to solve the disagreements as much as possible. And it can improve the rationality of subjective probability through the various aspects of them.The personal and subjective tendency and logical rationality will be unified by the same public knowledge and subjective assignment in order to find the points of three-door dilemma.
