Offender Profiling
Psychology: AQA A Level, topic 16.1.3
Offender Profiling: Typology
Offender profiling attempts to develop a set of characteristics of people that commit a specific crime. There are two main methods: a typology and a data-driven approach.
Purpose of offender profiling
- The purpose of offender profiling is to help police in catching the offender.
- The police can look at the profile and focus their resources and time on specific types of individuals.
- The first type of offender profiling is the ‘typology’ approach.
Typology approach
- The FBI first developed the typology approach.
- They examined and interviewed people who had committed heinous crimes such as serial killing or rape murders to develop a general description of people who commit these types of crimes.
- The FBI interviewed 36 of these convicted individuals.
- They were categorised into two groups: organised and disorganised.
Organised criminals
- Organised criminals were classified as those who are:
- Intelligent
- Socially and sexually competent
- Did not live alone
- Planned their attacks.
Disorganised criminals
- On the other hand, disorganised criminals were classified as those who were
- Not as intelligent
- Socially and sexually incompetent
- Lived alone
- Were spontaneous in their attacks.
Strengths
- Using information gathered from these interviews, FBI investigators were able to examine new crime scenes with insight into the behaviour of the individual.
- The Netflix show Mindhunters portrays the early days of FBI criminal profiling.
Limitations
- A disadvantage of this approach is the fact that the crime is self-reported, which means the research lacks validity.
- As well, the sample is completely restricted to these 36 convicted felons, this means their findings cannot be generalised to the public.
Data-Driven Approach
Offender profiling attempts to develop a set of characteristics of those that commit a specific crime. There are two main methods: a typology and a data-driven approach.
David Canter (1994)
- The second type of offender profiling is the ‘data-driven’ approach.
- This is the type used by British investigators.
- The approach was developed by David Canter (1994).
Geographical profiling
- Canter developed geographical profiling which involves gathering information from the crime scene and developing a profile of the criminal from there.
- It uses investigative psychology which applies psychological theories and research to criminal investigations.
Individual focus
- It is described as ‘data-driven’ as the focus is on the individual person committing the crime and the unique circumstances in which the crime took place.
- A fictional example would the television show Criminal Minds which takes into account the circumstances of the crime to develop a profile.
Typology & Data-Driven Approaches
Each type of profile looks at a different set of factors.
Typology approach
- The typology approach used four main stages to develop a profile.
- This was studied by Douglas et al (1986).
Four stages
- Collecting information from the crime scene and victim.
- Classifying the crime.
- What type of crime was it?
Four stages cont.
- Reconstructing the crime.
- How did both the offender and the victim behave?
- Creating a profile.
- They can determine if the criminal was organised or disorganised.
- The profile tries to determine both physical and lifestyle characteristics of the criminal.
Data-driven approach
- The data-driven approach uses geographical profiling developed by David Canter (1994).
- There are five characteristics that should be in the profile.
Five characteristics
- Personal characteristics
- E.g. personality traits.
- Criminal history
- Are they likely to have committed previous crimes or related crimes?
- Residential location
- Circle theory states that if you draw a circle around all of the locations of the crime scenes, the offender is likely to live in the middle.
Five characteristics cont.
- Domestic and social characteristics.
- Do they live alone?
- Do they have a family?
- Are the sociable and outgoing or reserved and withdrawn?
- Occupational and educational history.
- Do they have a job or are unemployed?
- What level of education and qualifications are they likely to have?
