Entomology is the scientific study of insects, a branch of zoology. In the past the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use.
Antisocial personality disorder, sometimes referred to as dissocial personality disorder, is a personality disorder characterized by a limited capacity for empathy and a long-term pattern of disregard for or violation of the rights of others. Other notable symptoms include impulsivity, reckless behavior, a lack of remorse after hurting others, deceitfulness, irresponsibility, and aggressive behavior.
Remorse is a distressing emotion experienced by an individual who regrets actions which they have done in the past that they deem to be shameful, hurtful, or wrong. Remorse is closely allied to guilt and self-directed resentment. When a person regrets an earlier action or failure to act, it may be because of remorse or in response to various other consequences, including being punished for the act or omission. People may express remorse through apologies, trying to repair the damage they've caused, or self-imposed punishments.

Psychopathy, or psychopathic personality, is a personality construct characterized by impaired empathy and remorse, and bold, disinhibited and egocentric traits, masked by superficial charm and the outward appearance of apparent normalcy.
The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those high in this trait from those with antisocial personality disorder, a related diagnosable disorder. It is a 20-item inventory of perceived personality traits and recorded behaviors, intended to be completed on the basis of a semi-structured interview along with a review of "collateral information" such as official records. The psychopath tends to display a constellation or combination of high narcissistic, borderline, and antisocial personality disorder traits, which includes superficial charm, charisma/attractiveness, sexual seductiveness and promiscuity, affective instability, suicidality, lack of empathy, feelings of emptiness, self-harm, and splitting. In addition, sadistic and paranoid traits are usually also present.
The dark triad is a psychological theory of personality, first published by Delroy L. Paulhus and Kevin M. Williams in 2002, that describes three notably offensive, but non-pathological personality types: Machiavellianism, sub-clinical narcissism, and sub-clinical psychopathy. Each of these personality types is called dark because each is considered to contain malevolent qualities.
The Psychopath Test: A Journey Through the Madness Industry is a 2011 book written by British author Jon Ronson in which he explores the concept of psychopathy, along with the broader mental health "industry" including mental health professionals and the mass media. It spent the whole of 2012 on United Kingdom bestseller lists and ten weeks on The New York Times Best Seller list.
The Psychopathic Personality Inventory (PPI-Revised) is a personality test for traits associated with psychopathy in adults. The PPI was developed by Scott Lilienfeld and Brian Andrews to assess these traits in non-criminal populations, though it is still used in clinical populations as well. In contrast to other psychopathy measures, such as the Hare Psychopathy Checklist (PCL), the PPI is a self-report scale, rather than an interview-based assessment. It is intended to comprehensively index psychopathic personality traits without assuming particular links to anti-social or criminal behaviors. It also includes measures to detect impression management or careless responding.
The Levenson Self-Report Psychopathy scale (LSRP) is a 26-item, 4-point Likert scale, self-report inventory to measure primary and secondary psychopathy in non-institutionalized populations. It was developed in 1995 by Michael R. Levenson, Kent A. Kiehl and Cory M. Fitzpatrick. The scale was created for the purpose of conducting a psychological study examining antisocial disposition among a sample of 487 undergraduate students attending psychology classes at the University of California, Davis.
Psychopathy, from psych and pathy, was coined by German psychiatrists in the 19th century and originally just meant what would today be called mental disorder, the study of which is still known as psychopathology. By the turn of the century 'psychopathic inferiority' referred to the type of mental disorder that might now be termed personality disorder, along with a wide variety of other conditions now otherwise classified. Through the early 20th century this and other terms such as 'constitutional (inborn) psychopaths' or 'psychopathic personalities', were used very broadly to cover anyone who violated legal or moral expectations or was considered inherently socially undesirable in some way.
George Everett Partridge was an American psychologist credited with popularizing the term sociopath in 1930 that Karl Brinbaum had suggested in 1909. He worked with the influential G. Stanley Hall at Clark University. One year after his death, the George Everett Partridge Memorial Foundation was incorporated in 1954 by the Partridge family to memorialize his life's work in the study and treatment of mental and personality disorders. The Foundation focused on developing programs to promote treatment centers for mentally disabled children, often referred to as the "forgotten children." Partridge schools were established. The first of which was in Herndon, Virginia, for older boys with moderate mental retardation resulting from brain damage. However, the foundation was forfeited in 1991.

The Society for the Scientific Study of Psychopathy is an international learned society dedicated to promoting and advancing scientific research on the personality disorder psychopathy. It was established in 2005 and held its first meeting that year in Vancouver, British Columbia, Canada. Since then, the society has held biennial conferences to provide a venue for psychopathy researchers to present their most recent findings. As of 2009, the society had over 160 members, most of whom were from the United States.
In the field of personality psychology, Machiavellianism is the name of a personality trait construct characterized by interpersonal manipulation, indifference to morality, lack of empathy, and a calculated focus on self-interest. Psychologists Richard Christie and Florence L. Geis named the construct after Niccolò Machiavelli, as they used truncated and edited statements inspired by his works to study variations in human behaviors. Their Mach IV test, a 20-question, Likert-scale personality survey, became the standard self-assessment tool and scale of the Machiavellianism construct. Those who score high on the scale are more likely to have a high level of manipulativeness, deceitfulness and a cynical, unemotional temperament.
The influence of childhood trauma on the development of psychopathy in adulthood remains an active research question. According to Hervey M. Cleckley, a psychopathic person is someone who is able to imitate a normal functioning person, while masking or concealing their lack of internal personality structure. This results in an internal disorder with recurrent deliberate and detrimental conduct. Despite presenting themselves as serious, bright, and charming, psychopathic people are unable to experience true emotions. Robert Hare's two factor model and Christopher Patrick's triarchic model have both been developed to better understand psychopathy; however, whether the root cause is primarily environmental or primarily genetic is still in question.
