defining and measuring crime
Evaluation of defining a crime
Universal concepts
- Despite variations in how crime are identified there are some behaviours that are universally regarded as unacceptable such as murder, rape and theft
- However even within these categories there are cultural variations in the law for example the French concept of a crime of passion may lead to a more lenient sentence for a murder if the court decides the murder acted on unplanned impulse
Evaluation of measuring a crime
Official statistics
- Only a certain number of crimes make it through the crime funnel and get reported to the police
- May be for a variety of reasons for example a victim may not feel the police will take it seriously enough so therefore do not report it or they may wish to avoid the stigma of being a victim or a person may not even be aware that a crime has been committed
- Walker et al found that only 42% of crimes reported in the British crime survey were reported to the police, this is called a dark figure of unreported crime and means that official statistics only represent a part of criminal activity on the other hand general trends reported from both kinds of statistics tend to be in agreement such as increases vehicle thefts

offender profiling: the bottom up approach
Evaluation
Scientific basis of the bottom-up approach
- One advantage claimed from bottom-up approaches is that they are considered to be more scientific than top down approaches because of the use of objective statistical techniques and computer analysis
- Techniques are only as good as the data that is input and underlying assumptions used to work out links between data items
- One issue is that the data that is used to drive such systems is only related to offenders who have been caught and therefore this tells us little about patterns of behaviour related to unsolved crimes
- Someone has to develop the formula and this may be incorrect
- This means that bottom-up approaches may have the potential to be objective and systematic but in practise they are inevitably biased
Is investigative psychology useful
- Canter very first attempt at profiling was very impressive and led to police interest in the method
- Some research supports the usefulness of the approach, Gary Copson surveyed 48 UK police forces using investigative profiling and found that over 75% of the police officers questioned said that the profilers advice had been useful
- Only 3% said that the advice had helped identify that actual offender but said that they would use it again
- This suggests that the method may not be useful in actually catching offenders but the slight benefit that it
affords makes it worthwhile
Is circle theory successful
Is geographic profiling generally successful
Final conclusions
Biological explanations of offending behaviour: A historical approach
contribution to the science of criminology
criticisms of Lombroso’s methods
Gender bias
Criticisms of somatotypes
Links between personality type and criminality
Biological explanations of offending behaviour: Genetic
Genetic explanations
research support from adoption studies
- twin studies are not the only kind of genetic research undertaken that indicates there is some element of inheritance in offending behaviour
- another line of evidence comes from adoption studies
- Crowe found that adopted children who had a biological parent with a criminal record had a 50% greater risk of having a criminal record by the age of 18 whereas adopted children who didnt have a criminal mother only had a 5% risk
- Mennick et al study of 14,000 adoptees found that 15% of sons adopted by a criminal family went on to be criminals compared to 20% whose biological parents were criminals suggesting that inherited genes are marginally more significant factor
can genetic and neural explanations explain non violent crimes
problems with determinism explanations
Psychological explanations of offending behaviour: Eysenck;s Theory
research on the genetic basis of personality
personality may not be consistent
personality tests may not be reliable
support for link between personality and criminal behaviour
basis as a theory of offending behaviour
Psychological explanations of offending behaviour: Cognitive distortions
Research support for hostile attribution bias
research support for minimalisation
real world application
Psychological explanations of offending behaviour: Level of moral reasoning
research support
limitations of Kohlbergs theory
Real world application
Psychological explanations of offending behaviour: Psychodyanmic
important consideration of emotion
not causal findings
real world application
gender bias in Freud’s theory
complex set of factors
- Bowlby acknowledged that juvenile delinquency is undoubtedly the consequence of many complex factors such as poverty, bad housing and lack of recreational facilities, none of these actually figure in psychodyanmic explanations but still has a contribution to make
Farrington et al did a 40 year longitudinal study in the UK with 400 boys from South London
- study concluded that the most important risk factors at age 8-10 for later offending was
1. family history of criminality
2. daring or risk taking personality
3. low school attainment
4. poverty
5. poor parenting
- shows explanations can be combined
