Depending on a theoretical approach, victimology is considered to be an independent scientific discipline analysing the problems of social mechanisms that lead to someone becoming a victim, or a scientific discipline focused on the mechanisms of victimization; that is, the process of becoming a victim of criminal offences, and working out the methods of preventing victimisation or, at least, diminishing the susceptibility to this phenomenon. The latter is understood as a factor that especially facilitates becoming a probable victim. Victimology is not by any means a science serving the justification of criminals’ deeds (e.g. rapists accusing women of provocative clothing) but it aims at expanding one’s knowledge of social mechanisms of crime, developing social awareness of the way certain behaviours or life choices favour crimes, provoking criminals into committing crimes. In other words, the article presents how one may become a victim unknowingly. One of the categories of victimology is susceptibility to victimisation. This article is focused on this particular area in the context of the methods preventing victimisation.
