How effective is criminal profiling?
Introduction
The issue of 'criminal profiling' is one with which most of us are familiar. Its recent appearances in
the media have certainly raised the profile of criminal psychology and a number of students are
keen to work in this area. "Numerous TV programmes and documentaries have also in recent times
focused around the assertion of criminal profiling, including Millennium, profiler and even The X-
Files" (Muller, 2000:234). Unfortunately, the media portrayal of criminal profiling has often been
far from accurate. The basic reason for this is because they have a tendency to imply that profiling
is a perfect skill to some extent comparable to a precognitive clairvoyant capability (Muller, 2000).
As a result of the general popularity of criminal profiling, much has been written on this topic and a
comprehensive review of the literature is beyond the scope of this paper (Muller, 2000). Profiling
has its proponents among those who understand the process and have had successful experiences
with it (Ault et al., 1994; Douglas and Burgess 1986; Douglas et al., 1986; Geberth, 1996). The
understanding of profiling as an investigative technique is still not well known by many law
enforcement professionals including criminologists, and behavioural scientist (Cook and Hinman,
1999). According to different authors including forensic psychologist and FBI-trained profiler,
criminal profiling can be a very useful tool in the investigation of very violent crime. The present
development of criminal profiling has been said to be more art than science. "Most criminal
profiling uses information drawn from forensic and behavioural science, but the scientific merit of
profiling has not yet been demonstrated in a systematic fashion" (Cook and Hanman, 1999: 231).
What is criminal profiling?
Criminal profiling is the inferring of an offender's characteristics from his or her crime scene
behaviour. According to Douglas and Olshaker (1995)"Criminal profiling is the development of an
investigation by means of obtainable information regarding an offence and crime scene to compile a
psychosomatic representation of the known architect of the crime." (Douglas and Olshaker, 1995
quoted in Muller, 2000:235). For example, a profiler might try to infer a criminal's age, gender or
employment history commencing from the manner he or she have performed throughout the period
the crime was carried out. This practice has been referred to by names including offender profiling,
psychological profiling and specific profile analysis. Criminal profiling is typically used with
crimes where the offender's identity is unknown and with serious types of crime where the
offender's identity is unknown and with serious types of crime, such as murder or rape. Profilers are
also likely to work on crime series, which are collections of crimes that are thought to have been
committed by the same offender (Bull et al., 2006). The different types of criminal profiling can be
How effective is criminal profiling?
broken broadly into two types: geographical profiling (which is how the offenders got to and from
the crime) and the profiling of an offender's personal characteristics. The latter is what people most
commonly associate with the term criminal profiling (Bull et al., 2006; Muller 2000).
The types of tasks that a criminal profilers might be asked to complete depend on the type of
profiler they are. A geographical profiler could be asked to identify the likely location of an
offender home from the geography of his or her known offences. A criminal profiler might be asked
to construct a profile of an unknown offender giving details of his or her likely characteristics as
inferred from the offender's behaviour at the crime scene. When a criminal is apprehended the
profiler might also be asked to advise the police on the way that particular suspects should be
interviewed. From all indications, criminal profiling is therefore an umbrella term for a number of
different practices (Ainsworth, 2001).
Having identified what criminal profiling is, we should address the question 'Who are criminal
profilers?' In 1995, Gary Copson investigated this issue and found that the majority of profilers in
Britain were typically academic or criminal psychologists. Psychiatrists, police officers and police
civilian staff were also represented within his sample of offender profiler: clearly criminal profilers
are themselves a varied group of people. The media has portrayed criminal profiling as a job in
itself, but in reality, only few individuals, within the United Kingdom at least, conduct criminal
profiling full-time. Most offender profilers are called in as consultants: the role is not as widely
practised as the media portray. For example, Copson's study found only seventy-five instances of
offender profilers giving advice in 1994, and this was the highest number recorded in one year for
the time span of his study (Copson, 1995). A number of different materials can be used by a
criminal profiler in constructing a profile or in geographically profiling an offender’s likely home.
One of the most important sources of information for constructing a profile would be the victim's or
witnesses' accounts of the crime. In some types of crime it is possible that a victim's account may
not be available, for example in the case of murder. In such cases, an offender profiler might instead
have to rely on post-mortem reports, sketches of the crime scene and accounts from others about the
victim. Regardless of the documentation used in constructing the profile, a criminal profiler has a
lot of information to absorb and process when trying to profile the offenders or their location (Bull
et al., 2006).
Geographical profiling is typically used to identify the likely area of an offender's residence from
the location of the crime. Such an approach can be very useful in narrowing down a pool of
suspects or enabling the police to prioritize an area for investigation or DNA sampling.
How effective is criminal profiling?
Geographical profiling has its history in environmental criminology. The aim of environmental
criminologists to identify areas where criminals were likely to offend from the locations of the
offender's residence: the aim of geographical profiling is the reverse. Using the locations of an
offender’s crime as his or her starting point, the geographical profiler tries to predict the area in
which the offender lives (Canter, 2000). Routine Activities Theory and Pattern Theory are relevant
to geographical profiling. This suggests that criminals will offend in an area with which they are
familiar. In other words, while criminals are going their daily life, they will notice potential targets.
The area with which criminals are familiar and which surrounds their residence has been called the
'home range', while the area in which they commit crimes has been called the 'criminal range'.
These theories also relate to the idea in geographical profiling that offenders have a cognitive or
mental map of their (Familiar) geographical areas. These theories have led to the development in
criminal psychology of geographical profiling principles and definitions of types (i.e. typologies) of
offenders. Two researchers have been largely responsible for these developments: Dr Kim Rossmo
and Professor David Canter. Both have developed typologies of offenders which have some
similarities (Canter and Alison, 1999; Rossmo, 2001).
Research with stranger rapists (rapists that attack victims previously unknown to them) and serial
arsonists has confirmed that for these types of criminals, the marauder pattern of offending is more
common, whereas the pattern for serial burglars is less clear. However, research has suggested that
offenders may change their geographical pattern of offending, sometimes behaving as marauders
and at other times behaving as commuters. One study examined a serial who offended in Italy over
a considerable number of years and it revealed that the offender sometimes behaved as murder but
at other times as a commuter. Clearly it would be unwise to assume that offenders fit on typology or
another (Grubin et al., 2001). Geographical profiling principles have been developed in England for
the marauder type of offender by Professor David Canter and colleagues. These are based on the
Circle Theory of Environmental Range which predicts that all things being equal, the shape of an
offender's criminal and home range will be circular, with the home itself being located in the centre
of the circle (Rossmo, 2001). As well as relying on statistical approaches for geographical profiling,
geographical profilers also consider issues such as the offender's likely motivation for the offences
and the characteristics of the physical environment in which his or her offending takes place. Such
factors could skew an offender's journey to crime and therefore affect the appropriateness of
statistical models (Jackson and Bekerian 1997).
The effectiveness of geographical profiling has not received a great deal of attention, though there
are some reports regarding its accuracy. For example, between 1991 and 2001 Rossmo's
How effective is criminal profiling?
geographical profiling system, Rigel, was used in the investigation of 1,426 crimes. Its effectiveness
was assessed by comparing the size of the total area over which the offences occurred to the
(smaller) size of area beginning to be searched on the basis of the geographical profile. On average,
the offender's residence was currently identified having searched approximately just the central five
per cent of the offence area. Its effectiveness seemed to vary depending on the type of crime, with it
being most effective for arson (Alison et al., 2002).
In asking how effective criminal profiling is, they should be an establishment with some reliability
of whether Profiling is of any importance or advantage to us first. Several law enforcement officers
including the police have revealed an immense agreement of doubt about profiling, to some certain
extent that can be due to the fact that they see apprehending criminals as their particular area of
proficiency, but also because it is still such an inadequately developed field (Davies, 1994). Modern
studies such as those conducted by Pinizzotto and Finkel (1990) suggest that profiling to some
extent valid. The effectiveness of criminal profiling in reality relies on the extent of which profiling
has actually been performed in practice. “Wilson et al. (1997) propose, to some extent idealistically,
that subsequent to focusing at the track documentation of profiling so far the proposition is that it
works. They have concentrated their claim on a case study of carefully selected high profile crimes;
however do not provide whichever references or source for the data. The major predicament in the
company of this claim is that it is entirely unreliable. associated to that is the dilemma of reporting
bias, for the reason that what is principally prone to be heard is all with reference to cases in which
profiling has been used if the case was lucratively and productively resolved with a success story
and of which the profile was close to perfect” ( Muller, 2000:259). The organisation of FBI is one
of the investigating team that is justifiably, unwilling to make public let go of the exact figures on
the successes and failures of the profiles that they present. “According to Ressler & Shachtman
(1992), data’s such as an 80% achievement rate have been circulated, there has yet to be any
statistics put forward to authenticate this claim” (Muller, 2000: 259).
Clearly an inaccurate criminal profile has the possibility to give the wrong impression about the
investigation; however this possibly will only be a setback if the police consign a superior quantity
of confidence in the criminal profile than they do in their personal investigative skills. “For
instance, Pinizzotto found that from 192 requests for criminal profiles, only 17% in fact were used
to help recognize the suspect. More positively, 77% of the respondents reported that the profile had
helped them to focus their investigation” (Muller, 2000: 259-260). Overall, if consistently profiles
are found not to be correct in some aspects, it may lead to police loosing absolute faith in their
worth.
How effective is criminal profiling?
A very crucial criticism of criminal profiling is the fact that there are no much studies showing or
demonstrating the techniques of profiling to be dependable and valid. “The majority of the 152
police psychologists surveyed by Bartol (1996) reported that they were sceptical about the validity
and usefulness of profiling.” (Cook and Hinman, 1999: 236).
For now, it seems impossible to no how effective criminal profiling actually is. This is mainly
because it’s based on too much assumption. For instance, when profiling the characteristics of a
person, the profiler is assuming that the behaviours shown at the crime scene are a result of the
person characteristics rather than determined by the situation. To successfully profile personal
characteristics from crime scene behaviour there would have to be some elements of the crime
scene behaviour that are more indicative of the person than of the situation. In recent studies, one
task for researchers of criminal profiling is to determine which behaviours these are. Typically, the
types of characteristics described in a criminal profile are demographic. In such situations the
profiler is therefore assuming a relationship between behaviour and demographic characteristics.
Some researchers have however, questioned whether a criminal demographic characteristic would
influence their behaviour and queried their inclusion in criminal profiles. Instead, as suggested by
personality psychologists, it is more likely that a person’s thoughts, goals, emotions and past
experiences will affect their behaviour in a situation. Criminal profiles that infer how a criminal will
perceive situations or infer his or her likely past experiences might therefore be more valid than
those inferring demographic characteristics. However, it is questionable how useful such
information would be to the police (Alison, 2005; Rossmo, 2001; Bull et al., 2006).
Researchers from personality psychology have spent a great deal of time investigating the
effectiveness of some of these assumptions and criminal psychologists have also begun to test them
empirically. In the published literature and on the internet it is easy to find case studies of
successful applications of criminal profiling to real criminal investigations. At face value this is
indeed good news. However, when reading such reports it is important to remember that the
successful cases are those most likely to be publicized. While it is very positive that profiling has
been successful in specific practice that its effectiveness is demonstrated through empirical
research.
Some empirical evaluations of criminal profiling have been conducted. Two studies attempted to
profile stranger rapists’ criminal histories from their crime scene behaviour and both reported some
limited success. A study that tried to predict the characteristics of burglars from their scene
behaviour also achieved some success in predicting characteristics such as criminal demographics

and previous criminal history. These studies have searched for relationships between criminal
characteristics and actions at the behavioural level. Other recent studies have investigated such
relationships at a thematic level: themes that describe the actual behaviours, for example, pseudo-
intimate behaviours, are developed (Bennell and Jones, 2005).
As well as actually testing whether criminal profiling is effective, some researchers have conducted
consumer satisfaction surveys, asking the users of criminal profiles to rate their usefulness. In
Britain, Gary Copson found that over seventy-five percent of the police officers questioned found
the profilers’ advice useful. This was mainly, because they said it increased their understanding of
the offender or supported their perceptions of the offence/offender. However, only three percent
said the advice had helped identify the actual offender. Most of the police officers did say that they
would seek the advice of a profiler again (Copson, 1995). A similar study was conducted in the
Netherlands, where only six profiles existed which could be assessed. In contrast to the British
study, the feedback from the police officers was negative. Most complained that the advice in the
profile was too general or was not practical given the resources the officers had available to them.
Some indicated that the profiler’s advice was ignored because it did not match their own opinions.
These findings cannot be given too much weight, however, since they are based on a very small
sample of officers (Jackson et al., 1993).
Conclusion
Criminal profiling has captured the interest of the public and students of criminal psychology alike.
In contrast to its portrayed in popular media, it is a field in its infancy which still requires a lot of
development, particularly in relation to establishing a solid theoretical base and evaluating its
effectiveness in a methodologically rigours way (Bull, 2006). The effectiveness of a criminal profile
is incorrect or even to some extent may inadequate mislead police, allowing the criminal to escape
detection for a little while longer and an innocent person may be dead as a result. However, this
does not imply that profiles should be ignored or should never be used by police again, but that
profiling should be approached with caution. Criminal profiling should not be blindly accepted or
should not be relied on because it may be something that may not have any relationship to the real
truth (Muller, 1995).

Over the last decades of the twentieth century there has been a growth of interest in crime prevention across the varied constituencies of academic researchers, practitioners in the criminal justice system, private sector knowledge brokers, politicians and the public at large. In fact, crime prevention has become what may be termed a 'buzzword' in policy circles across most countries of the world (Hughes, 1998). According to some criminologist, the prevention of crime in today's society has become a major organizing principle of almost all Western criminal justice systems

Examined outcome and process differences in criminal personality profiling among 4 profilers (PFs), 12 detectives, 6 psychologists, and 6 undergraduates, using closed police cases (1 sex offense, 1 homicide). In the written profile task (the task that is more representative of what PFs actually do), PFs wrote more detailed and valid profiles than other Ss for both cases. An analysis of correct responses concerning the known sex offender for the sex offense case revealed that PFs scored significantly better than other Ss on a variety of measures; similar results were not revealed for the homicide case. PFs did not appear to process this material in a way qualitatively different from other Ss. (PsycINFO Database Record (c) 2014 APA, all rights reserved)

Discusses several points raised in the N. Poythress et al (see record 1993-19880-001) article on equivocal death analysis (EDA). The authors argue that since they are law enforcement professionals who use EDA as an investigative technique, they are not mental health professionals and do not need to hold to American Psychological Association guidelines.

Most approaches to offender profiling depend on a naïve trait perspective, in which the task of predicting personality characteristics from crime scene actions relies on a model that is nomothetic, deterministic, and nonsituationist. These approaches rest on two basic premises: behavioral consistency across offenses and stable relationships between configurations of offense behaviors and background characteristics. Research supports the former premise but not the latter. Contemporary trait psychology reveals that this is probably due to the fact that Person X Situation interactions have an effect on offense behavior. When profiling reports rely on a nalve trait approach, such reports should be used with caution in criminal investigations and not at all as evidence in court until research demonstrates its predictive validity.

The term 'profiler' has commonly been applied to the media hungry defintion of a sole individual responsible for solving an offence where others have failed. This chapter extends the meaning to any individual or self professed 'expert' who has attempted to explain the motivations of others and categorise certain details of their backgrounds. This may include clients within therapy, suspects within a police enquiry or assessments of the likely motives and qualities that lîe behind different written texts. In expanding the term this chapter explores the extent to which profiling has been abused. Where the area has been redolent with poor policy and practice we attempt to outline an alternative to the scenario of the lonely expert contributing to the enquiry. Thîs involves closer lîaison with and education of the individuals relevant to the enquiry and of conceptual and empîrically derivable hypotheses appropriate to developing systematic and replicable models of behaviour set within a social science framework.

Criminal profiling is designed to generate information on a perpetrator of a crime, usually a serial offender, through an analysis of the crime scene left by the perpetrator. The two main approaches to criminal profiling, crime scene analysis and investigative psychology, are examined for the presence of a paradigm and the possibility of falsifiability to determine whether they can be considered as science.
Article
Criminal profiling is a useful investigative technique that combines art and science. This article provides a brief overview of profiling that includes discussions of definitions of profiling, the training and expertise necessary to do profiling, how profiling can be helpful in criminal investigations, the types of crimes that lend themselves to profiling, and the profiling process. The current scientific status of profiling is reviewed, and suggestions are made for future research establishing the reliability and validity of the technique, and updating and expanding the database from which the behavioral analyses in profiling are deduced.
