What is offender profiling?
A behavioural and analytical tool that is intended to help investigators accurately predict and profile the characteristics of unknown criminals.
It assists in narrowing down potential suspects based on crime scene evidence.
What is top-down profiling?
Profilers start with a pre-established typology and work down in order to assign offenders to one of two categories based on witness accounts and evidence from the crime scene.
This method relies on existing categories and frameworks.
Define an organised offender.
An offender who shows evidence of planning, targets the victim, and tends to be socially and sexually competent, with higher-than-average intelligence.
Organised offenders are often meticulous and leave fewer clues.
Define a disorganised offender.
An offender who shows little evidence of planning, leaves clues and tends to be socially and sexually incompetent, with lower-than-average intelligence.
Disorganised offenders often act on impulse and may leave behind more evidence.
What is the bottom-up approach in profiling?
Profilers work up from evidence collected from the crime scene to develop hypotheses about the likely characteristics, motivations and social background of the offender.
What is Investigative Psychology?
A form of bottom-up profiling that matches details from the crime scene with statistical analysis of typical offender behaviour patterns based on psychological theory.
What is geographical profiling?
A form of bottom-up profiling based on the principle of spatial consistency - that an offender’s operational base and possible future offences are revealed by the geographical location of their previous crimes.
What is an atavistic form?
A biological approach to offending attributing criminal activity to offenders being genetic throwbacks or a primitive subspecies.
