Offender profiling , also known as criminal profiling , is an investigative strategy used by law enforcement agencies to identify likely suspects and has been used by investigators to link cases that may have been committed by the same perpetrator. The originator of modern profiling was FBI agent Robert Ressler . He defined profiling as the process of identifying all psychological characteristics of an individual and forming a general description of their personality based on an analysis of crimes they have committed.
83-463: The earliest reference to the use of profiling, according to R.S. Feldman, is Quintilian 's essay "Instruction to the Speaker", written in the 1st century AD. It included information about gestures used by people at that time. M. Woodworth and S. Porter believe that the first development on the topic of profiling should be considered the notorious Malleus Maleficarum ("Hammer of Witches"), written in
166-591: A close advisor of the Emperor, which probably ensured his survival after the assassination of Galba in 69. After Galba's death, and during the chaotic Year of the Four Emperors which followed, Quintilian opened a public school of rhetoric . Among his students were Pliny the Younger , and perhaps Tacitus . The Emperor Vespasian made him a consul . The emperor "in general was not especially interested in
249-475: A filthy dungeon. The influential scholar Leonardo Bruni , considered the first modern historian, greeted the news by writing to his friend Poggio: It will be your glory to restore to the present age, by your labour and diligence, the writings of excellent authors, which have hitherto escaped the researches of the learned... Oh! what a valuable acquisition! What an unexpected pleasure! Shall I then behold Quintilian whole and entire, who, even in his imperfect state,
332-582: A focus on correct predictions over the number of incorrect ones, ambiguous profiles benefiting from the Barnum effect , and the popular appeal of the fantasy of a sleuth with deductive powers like Hercule Poirot and Sherlock Holmes . Notable profilers include Roy Hazelwood , who profiled sexual predators; Ernst Gennat , a German criminologist, who developed an early profiling scheme for the police of Berlin; Walter Charles Langer , who predicted Hitler's behavior and eventual suicide; Howard Teten , who worked on
415-770: A link between crime scene actions (A) and offender characteristics (C), a necessary supposition of the A to C paradigm proposed by Canter (1995). A 2002 review by Alison et al. concluded, "The notion that particular configurations of demographic features can be predicted from an assessment of particular configurations of specific behaviors occurring in short-term, highly traumatic situations seems an overly ambitious and unlikely possibility. Thus, until such inferential processes can be reliably verified, such claims should be treated with great caution in investigations and should be entirely excluded from consideration in court." Quintilian Marcus Fabius Quintilianus ( Latin: [kᶣiːn.tɪ.li.ˈaː.nʊs] ; c. 35 – c. 100 AD)
498-480: A man of physical strength and great coolness and daring... subject to periodic attacks of homicidal and erotic mania. The characters of the mutilations indicate that the man may be in a condition sexually, that may be called Satyriasis ." In 1912, a psychologist in Lackawanna, New York delivered a lecture in which he analyzed the unknown murderer of a local boy named Joey Joseph, dubbed " The Postcard Killer " in
581-421: A mistake since the 1960s. Profilers have been noted to be very reluctant to participate in studies of profiling's accuracy. In a 2021 article it was noted that out of 243 cases, around 188 were solved with the help of criminal profiling. As of 2021, although the practice of offender profiling is widely used, publicized and researched globally, there is a significant lack of empirical research or evidence to support
664-503: A practical model in the art he was expounding, neither Aristotle, nor any less austere among the Greek rhetoricians, has any pretensions to measure himself with Quintilian. In reality, for a triumph over the difficulties of the subject, and as a lesson on the possibility of imparting grace to the treatment of scholastic topics, naturally as intractable as that of Grammar or Prosody, there is no such chef-d'œuvre to this hour in any literature, as
747-436: A profile than any other participating groups. A survey of statements made in offender profiles done for major cases from 1992 to 2001 found that "72% included repetition of the details of what occurred in the offence (factual statements already known by the police), references to the profiler’s competence [...] or caveats about using the material in the investigation." Over 80% of the remaining statements, which made claims about

After the war, British psychologist Lionel Haward , while working for the Royal Air Force police, drew up a list of characteristics which high-ranking war criminals might display. These characteristics were used to identify high-ranking war criminals amongst captured soldiers and airmen. Offender profiling

In 1968, he moved to New York City to work for the Associated Press until 1974 when he began work on his debut novel, Black Sunday . Harris avoids publicity and conducted few interviews between 1976 and 2019. At Baylor University, he met and married Harriet Anne Haley, a fellow student, in June 1961. They had one daughter, Elizabeth Anne, before they divorced in August 1968. Harris remained close to his mother Polly and called her every night no matter where he was. He often discussed particular scenes from his novels with her. Polly died on December 31, 2011. Harris lives in South Florida and has

In the United Kingdom, 29 profilers provided 242 instances of profiling advice between 1981 and 1994, its usage increasing steadily over that period. The usage of profiling has been documented in Sweden , Finland , New Zealand , South Africa , Germany , Canada , Ireland , Malaysia , Russia , Zimbabwe , and

Harris' friend and literary agent Morton Janklow said of him: "He's one of the good guys. He is big, bearded and wonderfully jovial. If you met him, you would think he was a choirmaster. He loves cooking—he's done
1162-413: A well-educated man, sent him to Rome to study rhetoric early in the reign of Nero . While there, he cultivated a relationship with Domitius Afer , who died in 59. "It had always been the custom … for young men with ambitions in public life to fix upon some older model of their ambition … and regard him as a mentor". Quintilian evidently adopted Afer as his model and listened to him speak and plead cases in
1245-406: A “professional” criminal profiler, and when considering that support for criminal profiling is largely based on the opinion of police officers. The most routinely used typology in profiling is categorizing crime scenes, and by extension offender's personalities, as either "organized" or " disorganized ". The idea of classifying crime scenes according to organized/disorganized dichotomy is credited to
1328-548: Is also seen in Luther's contemporary Erasmus of Rotterdam. He above all shaped the implicit depth of humanism and had studied at Steyn. It has been argued by a musicologist, Ursula Kirkendale, that the composition of Johann Sebastian Bach 's Das musikalische Opfer ( The Musical Offering , BWV 1079), was closely connected with the Institutio Oratoria . Among Bach's duties during his tenure at Leipzig (1723–1750)
1411-551: Is believed to have died sometime around 100 AD, not having long survived Domitian, who was assassinated in 96. The only extant work of Quintilian is a twelve-volume textbook on rhetoric entitled Institutio Oratoria (generally referred to in English as the Institutes of Oratory ), written around 95 AD. This work deals not only with the theory and practice of rhetoric, but also with the foundational education and development of
1494-476: Is given to him. Quintilian believed that "his style is for the most part corrupt and extremely dangerous because it abounds in attractive faults". Seneca was regarded as doubly dangerous because his style was sometimes attractive. This reading of Seneca "has heavily coloured subsequent judgments of Seneca and his style". Quintilian also made an impression on Martial , the Latin poet. A short poem, written in 86 AD,
1577-409: Is highly unregulated. There is no governing body which determines who is and who is not qualified to be a criminal profiler, and therefore those who identify themselves as criminal profilers may range from someone with minimal to someone with extensive experience in the realm of criminal investigation. In addition to the lack of criteria as to what makes an expert in the field of criminal profiling, there
1660-402: Is his criticism of the orator Seneca the Younger . Quintilian was attempting to modify the prevailing imperial style of oratory with his book, and Seneca was the principal figure in that style's tradition. He was more recent than many of the authors mentioned by Quintilian, but his reputation within the post-classical style necessitated both his mention and the criticism or back-handed praise that
1743-507: Is little empirical evidence supporting the accuracy of criminal profiling. There is an abundance of anecdotal support for criminal profiling, much of which originates from reports made by police officers and investigators regarding the performance of criminal profilers. However, law enforcement agents have been found to greatly support the use of criminal profiling, but studies have shown that detectives are poor profilers themselves. One study presented police officers with two different profiles for

However, in his celebrated Autobiography, John Stuart Mill (arguably the nineteenth-century's most influential English intellectual) spoke highly of Quintilian as a force in his early education. He wrote that Quintilian, while little-read in Mill's day due to "his obscure style and to
1909-451: Is some dispute over the real writer of these texts: "Some modern scholars believe that the declamations circulated in his name represent the lecture notes of a scholar either using Quintilian's system or actually trained by him". Institutio Oratoria (English: Institutes of Oratory ) is a twelve-volume textbook on the theory and practice of rhetoric by Roman rhetorician Quintilian. It was written around year 95 AD. The work deals also with
1992-619: Is still used successfully to this day. The historical roots of criminal profiling in the United States and Europe have been discussed elsewhere (1). Many European countries have now developed their own approaches to criminal profiling and established specialized academic research institutions and trained police units (1,6), for example, the German Bundeskriminalamt (7,8), implementing the first quality standards in 2003 (9,10), as well as Austria (11), Scandinavia (12), and
2075-509: Is the idea that an offender's crimes will tend to be similar to one another. Homology is the idea that similar crimes are committed by similar offenders. Fundamental assumptions that offender profiling relies upon, such as the homology assumption, have been proven outdated by advances in psychology and behavioral science. The majority of profiling approaches assume that behavior is primarily determined by personality, not situational factors, an assumption that psychological research has recognized as
2158-427: Is the unique similarities in each of the kills. Mainly, linkage analysis is used when physical evidence, such as DNA , cannot be collected. Labuschagne states that in gathering and incorporating these aspects of the offender's crime pattern, investigators must engage in five assessment procedures: One- Obtaining data from multiple sources. Two- Reviewing the data and identifying significant features of each crime across
2241-432: Is used to determine the possibility of a series of crimes as having been committed by one offender." Gathering many aspects of the offender's crime pattern such as modus operandi (MO), ritual or fantasy-based behaviors exhibited, and the signature of the offender, help to establish a basis for a linkage analysis. An offender's modus operandi is the habits or tendencies during the killing of the victim. An offender's signature
2324-466: The Barnum effect . In addition, an investigator's judgement of the accuracy of a profile is impacted by the perceived source of the information; if the officer believes that the profile was written by an “expert” or “professional”, they are likely to perceive it as more accurate than a profile written by someone who is identified as a consultant. This poses a genuine problem when considering that there are no true criteria which determine who may be considered
2407-666: The Boston Strangler for the Boston Police Department . In 1972, after the death of J. Edgar Hoover , who was skeptical of psychiatry, the Behavioral Science Unit of the FBI was formed by Patrick Mullany and Howard Teten . Investigations of serial killers Ted Bundy and Gary Ridgway were performed in 1984 by Robert Keppel and psychologist Richard Walter . They went on to develop

Quintilian's definition of rhetoric shares many similarities with that of Cicero, one being the importance of the speaker's moral character. Like Cicero, Quintilian also believes that "history and philosophy can increase an orator's command of copia and style;" they differ in that Quintilian "features

2739-544: The Netherlands . Surveys of police officers in the United States, the United Kingdom, and Canada have found an overwhelming majority consider profiling to be useful. A 2007 meta-analysis of existing research into offender profiling noted that there was "a notable incongruity between [profiling's] lack of empirical foundation and the degree of support for the field." Profiling's continued popularity has been speculatively attributed to broad use of anecdotes and testimonials,

The Middle Ages saw a decline in knowledge of his work, since existing manuscripts of Institutio Oratoria were fragmented, but the Italian humanists revived interest in the work after the discovery by Poggio Bracciolini in 1416 of a forgotten, complete manuscript in the Abbey of Saint Gall , which he found "buried in rubbish and dust" in

In addition, there are two sets of declamations, Declamationes Maiores and Declamationes Minores , which have been attributed to Quintilian. However, there

There is also an opinion that the first "professional profiler" was the protagonist of Edgar Allan Poe's short story The Murders in the Rue Morgue (published 1841), who used the method of constructing a psychological portrait of the killer. The first work with a scientific approach (at the level of the 19th century)

An article in the April 1980 issue, "The Lust Murderer," introduced the dichotomy of "organized" and "disorganized" offenders. The August 1985 issue described a third, "mixed" category. In 1985, Dr. David Canter in the United Kingdom profiled "Railway Rapists" John Duffy and David Mulcahy . David Canter assisted police detectives from

A typology of serial sexual homicides advocated by Robert Keppel and Richard Walter categorizes them as either power–assertive, power–reassurance, anger–retaliatory, or anger–excitation.

A 2000 study also showed that profilers were not significantly better at creating

The BAU "assists law enforcement agencies by their review and assessment of a criminal act, by interpreting

In addition, he appeared in the courts of law, arguing on behalf of clients. Of his personal life, little is known. In the Institutio Oratoria , he mentions a wife who died young, as well as two sons who predeceased him. Quintilian retired from teaching and pleading in 88 AD, during

According to the BAU the probability of a profiler being used as "expert testimony" in court and leading to a guilty verdict is 85%. There is a difference between the hard sciences and the social sciences related to testimony and evidence in the courtroom. Some experts contend that offender profiling should not be used in court until such processes can be reliably validated, but as seen, it

In Book II, Quintilian sides with Plato 's assertion in the Phaedrus that the rhetorician must be just: "In the Phaedrus , Plato makes it even clearer that the complete attainment of this art is even impossible without the knowledge of justice, an opinion in which I heartily concur".

This enthusiasm for Quintilian spread with humanism itself, reaching northern Europe in the 15th and 16th centuries.

Domitian was in the harshest period of his rule at that time and almost no one had the courage to speak any idea that was unlike his, but Quintilian did. He spoke as an orator in the tradition of Cicero, such as had not been seen since the beginning of

His discussions of tropes and figures also formed the foundation of contemporary works on the nature of figurative language, including the post-structuralist and formalist theories.

[...] For both, there are conceptual connections between rhetoric and justice which rule out the possibility of [an] amorally neutral conception of rhetoric. For both, rhetoric is 'speaking well,' and for both 'speaking well' means speaking justly". The influence of Quintilian's masterwork, Institutio Oratoria , can be felt in several areas. First of all, there

Afer has been characterized as a more austere, classical, Ciceronian speaker than those common at the time of Seneca the Younger , and he may have inspired Quintilian's love of Cicero . Sometime after Afer's death, Quintilian returned to Hispania, possibly to practice law in the courts of his own province. However, in 68, he returned to Rome as part of the retinue of Emperor Galba , Nero's short-lived successor. Quintilian does not appear to have been

He and a colleague coined the term investigative psychology and began trying to approach the subject from what they saw as a more scientific point of view. The Crime Classification Manual was published in 1992, and introduced
4897-707: The multivariate analysis of behaviors and any other information from the crime scene that could lead to the offender's characteristics or psychological processes. According to this approach, elements of the profile are developed by comparing the results of the analysis to those of previously caught offenders. Wilson, Lincon and Kocsis list three main paradigms of profiling: diagnostic evaluation, crime scene analysis, and investigative psychology. Ainsworth identified four: clinical profiling (synonymous with diagnostic evaluation), typological profiling (synonymous with crime scene analysis), investigative psychology, and geographical profiling. Five steps in profiling include: One- Analyzing

There is a lack of clear, quantifiable evidence of

Another practitioner, Copson, outlined some principles for profiling which include being custom made, interactive and reflexive. By following these principles, the profile should include advice that is unique and not from a stereotype, should be easy to understand for all levels of intelligence, and all elements in the profile should influence one another. The Scientific approach relies heavily on

Quintilian also "insists that his ideal orator is no philosopher because the philosopher does not take as a duty participation in civic life; this is constitutive of Quintilian's (and Isocrates ' and Cicero 's) ideal orator". Though he calls for imitation , he also urges the orator to use this knowledge to inspire his own original invention. No author receives greater praise in

The United States Office of Strategic Services asked William L. Langer 's brother Walter C. Langer ,

Rather than pleading cases, as an orator of his era might have been expected to do, he concentrated on speaking in more general terms about how sound rhetoric influences the education of the people. Quintilian cites many authors in the Institutio Oratoria before providing his own definition of rhetoric . His rhetoric is chiefly defined by Cato the Elder 's vir bonus, dicendi peritus , or "the good man skilled at speaking". Later he states: "I should like

Quintilian survived several emperors; the reigns of Vespasian and Titus were relatively peaceful, but that of Domitian was reputed to be difficult. Domitian's cruelty and paranoia may have prompted the rhetorician to distance himself quietly. The emperor does not appear to have taken offence as he made Quintilian tutor of his two grand-nephews in 90 AD. He

Psychological profiling is described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics based on things done or left at the crime scene. There are two major assumptions made when it comes to offender profiling: behavioral consistency and homology. Behavior consistency
6142-621: The validity of psychological profiling in criminal investigations. Critics question the reliability, validity, and utility of criminal profiles generally provided in police investigations. Even over the years common criminal profiling methods have changed and been looked down upon due to weak definitions that differentiate the criminal's behaviors, assumptions and their psychodynamic process of the offender actions and characteristics that occur. In other words, this leads to poor and misleading profiles on offenders because they are based on opinions and decisions made up from one profiler conducting research on
6225-449: The years. In the year 2008, only 42% of cases were solved using criminal profiling. In 2019 the FBI was able to solve 56% of the cases that were not solved back in the year 2008. Profiling as an investigative tool has a high level of acceptance among both the general public and police. In the United States, between 1971 and 1981, the FBI had only profiled cases on 192 occasions. By 1986, FBI profilers were requested in 600 investigations in
6308-505: Was Charles Darwin's book The Expression of Emotions in humans and animals (1872). It contained only a description of external manifestations, but it was already a systematization — the beginning of a scientific study of the issue. An Italian psychologist Cesare Lombroso (1835-1909) was a criminologist who attempted to formally classify criminals based on age, gender, physical characteristics, education, and geographic region. When comparing these similar characteristics, he better understood
6391-648: Was a Roman educator and rhetorician born in Hispania , widely referred to in medieval schools of rhetoric and in Renaissance writing . In English translation, he is usually referred to as Quintilian ( / k w ɪ n ˈ t ɪ l i ən / ), although the alternate spellings of Quintillian and Quinctilian are occasionally seen, the latter in older texts. Quintilian was born c. 35 AD in Calagurris ( Calahorra , La Rioja ) in Hispania . His father,
6474-600: Was addressed to him, and opened, "Quintilian, greatest director of straying youth, / you are an honour, Quintilian, to the Roman toga". However, one should not take Martial's praise at face value, since he was known for his sly and witty insults. The opening lines are all that are usually quoted, but the rest of the poem contains lines such as "A man who longs to surpass his father's census rating" (6). This speaks of Quintilian's ambitious side and his drive for wealth and position. After his death, Quintilian's influence fluctuated. He
6557-441: Was based on his own examination of the most extensively mutilated victim and the post mortem notes from the four previous canonical murders. In his notes, dated November 10, 1888, Bond mentioned the sexual nature of the murders coupled with elements of apparent misogyny and rage. Bond also tried to reconstruct the murder and interpret the behavior pattern of the offender. Bond's basic profile included that "The murderer must have been
6640-498: Was first introduced to the FBI in the 1960s, when several classes were taught to the American Society of crime lab directors. There was little public knowledge of offender profiling until publicization with TV. Later films based on the fictional works of author Thomas Harris that caught the public eye as a profession in particular Manhunter (1986) and Silence of the Lambs (1991). The fastest development occurred when
6723-400: Was mentioned by his pupil, Pliny, and by Juvenal , who may have been another student, "as an example of sobriety and of worldly success unusual in the teaching profession". During the 3rd to 5th centuries, his influence was felt among such authors as St. Augustine of Hippo , whose discussion of signs and figurative language certainly owed something to Quintilian, and to St. Jerome , editor of
6806-541: Was so rich a source of delight?... But Quintilian is so consummate a master of rhetoric and oratory, that when, after having delivered him from his long imprisonment in the dungeons of the barbarians, you transmit him to this country, all the nations of Italy ought to assemble to bid him welcome... Quintilian, an author whose works I will not hesitate to affirm, are more an object of desire to the learned than any others, excepting only Cicero's dissertation De Republica. The Italian poet Petrarch addressed one of his letters to
6889-696: Was teaching Latin; his early training included rhetoric. (Philologist and Rector of the Leipzig Thomasschule, Johann Matthias Gesner , for whom Bach composed a cantata in 1729, published a substantial Quintilian edition with a long footnote in Bach's honor.) After this high point, Quintilian's influence seems to have lessened somewhat, although he is mentioned by the English poet Alexander Pope in his versified An Essay on Criticism : In grave Quintilian's copious works we find The justest rules and clearest method join'd (lines 669–70). In addition, "he
