Profiling Flashcards
What is profiling?
It is the process of drawing inferences about a criminal’s personality, behaviour, motivation, and demographic characteristics based on a crime scene and other evidence
What is the Purpose of Profiling
1- To help identify the suspect

3-Determine if a note should be taken seriously
4-how to cross examine at trial
when profiling what do we look for?
1-Personality
2- Motivations
3-Psychal traits
4- Demographic
5-signature
what are the Key features of profiling
WHY: MOTIVATION
WHAT: CRIME SCEME
WHO: SIGNATURE M.O
What is a M.O
- standar procedure
- what an offender does to accomplish the crime
- gets modified and perfected
What is a signature
- what makes the offender fulfilled emotionally
- not needed to complete the crime
Inductive vs Deductive Profiling describe each
Deductive:
- Logic
-Predict characteristics based on -evidence left
Ex: fingernails
-Can be faulty
Inductive:
-Use comparison
-Examine new crime scene & old
-Organized vs Disorganized
-Not helpful if unique
what is the organized behaviour and personality
Organized Behaviors
-Planned
-Use restraints
-Little evidence left
-Use of vehicle
-Corpse not taken
-No post-mortem acts
Organized Personality
-High intelligence
-Sexually adequate
-Lives with partner
-Follows crime in media
-Lives & works away from crime
what is disorganized behaviour and personality?
Disorganized Behaviors
-Impulsive
-No restraints
-Evidence left
-No use of vehicle
-Corpse taken
-Post-mortem acts
Disorganized Personality
-Low intelligence
-Sexually inadequate
-Lives alone
-Little interest in media
-Lives & works close to crimes
what are the 4 stages when fbi profile
stage 1- Data assimilation
they gather information from the police reports, crime scene, pathologist reports
stage 2- crime scene classification
is it organized or disorganized
stage 3 crime reconstruction
they create hypothesis: victim behaviour, crime sequence, modus operandi
stage 4: profile generation
demographic
psych characterics
behavioural habits
what is Statistical Profiling
-Simpler approach
-Same assumption»_space; crime –scene information can reveal -characteristics of the offender
-Establish relationships using stats
-Not intuition
in order words it takes a whole bunch of crimes and look for patterns
Overall the statistical approach
Statistical Approach to Profiling
1. Classifying
Info at crime scene»> can clusters be
formed?
- Do clusters reveal psychological & other features of the offender?
- Are patterns stable & consistent over time? (multiple crime scenes)
problem with profiling?
1-Profilers are not psychologists. FBI agents with no psychological background
2-Weak methodology used to build the “science”
3-Lacks support of scientific community
4-Poor predictive results (poor stats)
5-Use of intuition
why is profiling a weak method?
Based on John Douglas research
Only interviewed 35 serial killers
Other research
Small sample
Self-report
list of problems in details
- Poor Predictive Results
Stats do not support useful tool
Many cases where profile was not helpful
4-Use of intuition
Cannot be measured
Cannot be researched
