Psychological Factors Underlying Criminal Behavior

by

In old fashioned history books, the highest tribute paid to a king was to say that he was just, he helped the poor and punished the wicked. In those days a law-abiding people were sorely in need of protection against powerful law-breakers. Today the power of the state is firmly established. True, quite a number of crimes are never detected; but no criminal has the slightest chance of openly defying society. If we read of a manhunt in the country we give the poor devil a fortnight at the outside; we know that by then the armed machinery of the law will surely have overtaken him. Society has the right and the duty to protect itself. But its superiority in strength over the individual delinquent

Modeling of Human Criminal Behavior using Probabilistic Networks

by

Abstract

Currently, criminal’s profile (CP) is obtained from investigator’s or forensic psychologist’s interpretation, linking crime scene characteristics and an offender’s behavior to his or her characteristics and psychological profile. This paper seeks an efficient and systematic discovery of non-obvious and valuable patterns between variables from a large database of solved cases via a probabilistic network (PN) modeling approach. The PN structure can be used to extract behavioral patterns and to gain insight into what factors influence these behaviors. Thus, when a new case is being investigated and the profile variables are unknown because the offender has yet to be identified, the observed crime scene variables are used to infer the unknown variables based on their connections in the structure and the corresponding numerical (probabilistic) weights. The objective is to produce a more systematic and empirical approach to profiling, and to use the resulting PN model as a decision tool.

Family Violence and Criminal Behavior

Introduction

In the sociology of crime and criminality, emphasis is placed on cultural and group forces that produce actors who represent forms of deviance from the dominant value, or moral demand, system. The individual offender is not ignored; he is simply clustered with other individuals alike in attributes deemed theoretically or statistically meaningful. His "uniqueness" is retained by the improbability that on several attributes or variables he will appear identical to everyone else. Hence, the researchers resort to means, medians, modes, to probability theory, inferential statistics and mathematical models for analyzing predominant patterns and regularities of behavior. Biological and psychological factors are not ignored, but when a monodisciplinary perspective is used by sociologists, the bio-psychological is suspended, postponed or dismissed after consideration. Biological needs and psychological drives may be declared uniformly distributed and hence of no utility in explaining one form of behavior relative to another. They may be seen as differential endowments of personalities that help to assign, for example, a label of...

Passion Victim | A brief look at Hybristophilia

by

Hybristophilia was defined by the sexologist Professor John Money as a sexual paraphilia in which an individual derives sexual arousal and pleasure from having a sexual partner who is known to have “committed an outrage or crime, such as rape, murder, or armed robbery.” This type of paraphilic behaviour is sometimes colloquially known as ‘Bonnie and Clyde Syndrome.’ In some cases, the person who is the focus of the sexual desire is someone who has been imprisoned. In some cases, the hybristophile may urge and coerce their partner to commit a crime.

In other cases, the hybritophile may contact someone who is already in prison that they do not know except by reputation and/or what the have read or seen in the media. For instance, it is well known that serial killers—particularly those who have received lots of media publicity—receive lots of fan mail from female admirers (some of who are likely to be genuine...
