Inference Theory In Criminal Investigation

The Deducation theory is an important theory in logic circles, the inductive, deductive logic and said three branches. As a kind of practice in life are often used in logical reasoning tools, backtracking reasoning at home and abroad have aroused people’s great interest and attention, and has been more and more widely applied to investigation, medicine, physics and other fields. This paper is based on the original backtracking reasoning theory, the introduction of Western logicians in the backtracking reasoning is applied to the medical field is extended out of the new theory, so as to enrich the domestic theory research on backtracking reasoning, guide our legal practice.The article is divided into the following sections:The first part:this part mainly expounds the backtracking reasoning in history. First of all, the author from the west to introduce backtracking reasoning thought, from Aristotle to Qi Mubin Pinsky backtracking reasoning thought, the backtracking reasoning definition, reasoning model makes a brief statement, then the backtracking reasoning conclusion and classification briefly analysis. Secondly, the author describes the logic in China of the backtracking reasoning research status, mainly on the backtracking reasoning definition and reasoning structure are introduced and analyzed.The second part:this part mainly introduces The Deducation theory. Its main content is to introduce western logics circles, Magena backtracking theory research content. Was first introduced by the formation of hypothesis testing and hypothesis reasoning epistemology model, then turning the backtracking reasoning meaning, characteristics, classification and its deduction, induction difference. Secondly the author talks about three kinds of specific backtracking reasoning form-visual backtracking, tense backtracking, medical reasoning, focusing on the specific content of medical reasoning, which is mainly composed of diagnosis and treatment of two kinds of forms of reasoning. Next, the author describes the control of inconsistency and revocation of a scientific hypothesis, to control the consistency of the concrete steps and" failure of denial" theory is introduced in this paper.The third part:this part mainly on Deducation theory in China’s judicial practice. First of all, the author of Magena, backtracking reasoning for a brief evaluation, and then the author on the legal practical feasibility analysis. Secondly, the author draws lessons from the medical reasoning model, try to construct a derived investigation the backtracking reasoning model. Finally, the authors with specific case analysis, introduced the specific investigation of recalling inference pattern operation process.The fourth part:conclusion. Medical reasoning in the backward thinking helps us to further understand The Deducation theory, in which the new terms, model is helpful for us to better understand, master and use backtracking theory...
