Inductive Profiling and Deductive Profiling

Profiling is not simply drawing a general profile. In fact, it is a process that aims to reconstruct individual behavior. There are those who advocate opposing the use of the inductive method, used the FBI since 1984. Criminal profiling method is inductive generalization to an individual criminal behavioral characteristics shared by other criminals that have been studied in the past. It is the product of analysis that induces generalizations, predictions, estimates, and statistics from the initial data. The deductive method is argued to be a more powerful instrument, for it is used by the Criminal Profiling Unit, the new generation of profiling units established in most European countries. The deductive method of criminal profiling is based on the interpretation of forensic evidence, including photographs of the crime scene, autopsy reports, autopsy photographs and a detailed study of interactions aggressor / victim to rebuild as accurately as possible the patterns of the crime scene and from it the patterns of behavior of the perpetrator, his emotional characteristics, demographic and motivational indicate.

From these behaviors, it is to draw the latent motivations. In fact, nobody is without motivation and as such behavior meets every motivation. In light of the behavior observed on the scene, we can try to understand the underlying motivations (example when a criminal covers the head of the victim during the attack, we can assume he did because he knew the victim or because he could not bear the sight of his victim while he was assaulting). But behavior can be associated with several potential motivations. Only the analysis of elements from other crime scenes may lead to identify what is the most motivational basis that led to the crime. The profile is systematically established, using more or less long-term implementation of behaviors. We deduce the characteristics of the perpetrator and his actions likely to come from a now "t-1". And it was only after the arrest of the perpetrator that the profiler will confront the results of its analysis to reality. Should they also specify that the profiler must be objective? He does not judge according to its values ??and standards. It is based on facts and concrete evidence.

It is necessary to remember that psychological profiling is not to discover the author of assault offenses. But it limits the population of suspects, after following some of the essential guidelines of research investigation. Profiling is an exercise that must rely on arguments. But despite all the precautions some investigations may still remain unclear. 

Inductive Profiling is different from techniques that state facts observed in specific situations and in number, to general laws, and then seeks to find significant reasoning's for these inferences. Deductive profiling involves reaching conclusions that naturally follow certain assumptions: it is with a belief that these pressure assumptions are correct then the conclusions will be too. The deductive methods tend to stick to the information available in the case at hand level. When analyzing the available information in the ...
