Ronson examines the history of psychopathy, its definition and diagnostic criteria. Philippe Pinel first described “manie sans delire”—insanity without delusions—in early 19th-century France. J. L. A. Koch coined the term “psychopathy” in 1891. By the 1960s, the consensus held that 1% of people were “psychopaths,” prompting urgent questions about treatment and its efficacy. Ronson then discovered academic papers about a young Canadian psychiatrist named Elliott Barker, who believed he could cure individuals diagnosed as psychopaths. The papers described him in unusually warm, idealistic terms despite his unconventional methods. Barker and his colleagues developed their Oak Ridge program, an intensive treatment meant to cure psychopathy.
Curious about Oak Ridge, Ronson performed extensive research to uncover the story, eventually learning the full history. In the mid-1960s, Barker and his wife traveled worldwide visiting radical therapeutic communities. In Palm Springs, he encountered Paul Bindrim’s nude psychotherapy sessions featuring 24-hour marathons where participants stared at one another’s genitals and spoke unabashedly about their bodies and feelings. In London, Barker visited R. D. Laing and D. G. Cooper’s Kingsley Hall, where individuals with schizophrenia were allowed to work through their mental health crises without intervention—the psychiatrists believing mental disorders were curable if allowed to run their course. Barker would later marry these nontraditional psychotherapeutic elements into his own experimental project.
Determined to understand more, Ronson interviewed Adrian Laing, R. D. Laing’s son, who described Kingsley Hall’s dual nature: rooms with Indian silks hosting celebrities like Sean Connery, contrasted with Mary Barnes’s basement “shit room” (71). Encouraged by psychiatrists to return to her childlike self to grow beyond her schizophrenia diagnosis, Barnes lived naked, smeared her excrement on her walls and body, and ate from a bottle. Barnes was eventually given paints, which she began using in place of excrement, and went on to become a celebrated artist.
Ronson returns to Barker’s story, who took a job at Oak Ridge Hospital in Ontario after returning from his trip abroad. Theorizing that psychopaths buried insanity beneath more typical behavior, he obtained government-supplied LSD and created the Total Encounter Capsule—a small green room for 11-day nude therapy marathons. Psychopaths discussed feelings constantly while high on LSD, and ate through straws, as Barker watched from behind a one-way mirror. Visiting teenagers wore gruesome crime-scene photos to maintain the radical atmosphere.
One participant in the Total Encounter Capsule was Steve Smith, a former inmate recruited even though he was only a minor car thief. When Ronson met with him, Smith recalled 11 days locked in a padded room with serial killers while on hallucinogens. He was strapped to Peter Woodcock, a notorious child-killer serving as his “buddy.” They later got matching tattoos.
The program appeared successful. A 1971 CBC documentary showed prisoners expressing tenderness. Some requested delayed parole to complete the therapy. In the mid-1970s, Gary Maier, Barker’s hippie prodigy, took over the program. He introduced the Dream Group, where participants shared their dreams at length, and also led mass Om chanting.
In 1975, the Oak Ridge director Barry Boyd sent Maier a memo asking him to de-escalate LSD use. Maier had organized a mass LSD trip for 26 convicted murderers to prevent therapy regression. Angry guards changed the locks overnight, effectively firing Maier.
Now living and working outside the context of Oak Ridge, Barker continued his program, hosting released patients at his farm. His father had been a violent person with alcohol addiction who died by suicide when Barker was 10, which Ronson speculates inspired his lifetime of compassionate work.
Intrigued, Ronson wondered why a high-security psychiatric hospital like Broadmoor hadn’t adopted methods similar to Barker’s, particularly given their alleged success. Ronson soon discovered a study from the early 1990s, which found 80% of Oak Ridge graduates reoffended, compared to the typical 60% who had not participated in Oak Ridge, suggesting the program worsened outcomes. One Oak Ridge participant, Cecil Gilles, sexually assaulted a teenager days after release. Joseph Fredericks repeatedly reoffended after multiple releases, eventually murdering 11-year-old Christopher Stephenson. Notably, Peter Woodcock murdered fellow patient Dennis Kerr with a hatchet on his first three-hour pass in 1991, calling it curiosity. He said the program had taught him “to manipulate better” (88).
After the program ultimately ended, a crushed Barker became a director for the Canadian Society for the Prevention of Cruelty to Children. A former colleague said Barker later faced frequent malpractice suits from former patients.
Continuing his psychiatric investigations, Ronson met Bob Hare in rural Pembrokeshire, West Wales, and asked him about Barker and Oak Ridge. Hare mocked Oak Ridge’s approach. Hare argued that teaching empathy to psychopaths will always backfire because psychopaths use it as manipulation training. Ronson learns that Maier disagrees with Hare’s assessment, believing his firing from Oak Ridge caused psychopaths to reoffend as revenge. Ronson muses that unlike Barker and Maier, whose names have faded, Hare’s work has remained influential. Justice departments worldwide use his Psychopathy Checklist-Revised (PCL-R), which was also used to assess Tony at Broadmoor.
Ronson joined Hare’s three-day course on his checklist and how to use it. Some attendees were fans of Hare’s methods; others questioned whether it was fair to label people with a checklist. Hare promised Ronson that he would be among the former by the end of the program.
Ronson describes his experience at the conference and the insights he discovered about Hare and his work. Hare recounted starting as a prison psychologist in Vancouver in the mid-1960s. Psychopaths constantly tricked him—one ruined his uniform, another cut his brake cables. He devised detection tests to better understand the brains of people with psychopathy, strapping volunteers to monitors before administering painful electric shocks. Non-psychopaths showed rising fear; psychopaths showed no anticipatory response. Even repeated tests showed psychopaths didn’t learn from pain, suggesting threats of imprisonment would be meaningless to them. Hare concluded that the amygdala—a part of the limbic system meant to detect fear—does not function in a psychopath’s brain.
Another facet of Hare’s research was his Startle Reflex Test, where non-psychopaths leapt when viewing grotesque images, while psychopaths remained calm, suggesting fascination rather than horror. Science magazine rejected his findings, with the editor writing that “Those EEGs couldn’t have come from real people” (95).
When electric shocks were outlawed in the early 1970s, Hare shifted to behavioral observation. In 1975, he hosted a Les Arcs conference where 85 experts pooled observations of psychopathic behavior to make a more streamlined diagnostic consensus. The conference ultimately produced the 20-item PCL-R Checklist.
At the course Ronson attended, Hare played Case Study H’s video testimony. H exhibited atypical behaviors, which classified him as a psychopath according to Hare’s criteria. For example, he moved his chair under a panic button during an interview with one of Hare’s researchers as a subtle intimidation tactic. H also used detached language while describing breaking a boy’s arm, locking his stepmother in a closet for 12 hours, and manipulating a troubled youth into attacking three people in his parents’ house with a baseball bat, leaving one dead and two severely injured.
Amid the conference, Ronson describes feeling newly convinced of Hare’s methods and empowered to spot psychopaths himself. Privately, he began imagining using his skills against critic A. A. Gill.
Ronson continues detailing his experiences at the conference. Hare offered more examples of dangerous psychopathic behaviors. For example, he recounted Norman Mailer championing prisoner-writer Jack Henry Abbott’s 1981 parole. Abbott became literary New York’s toast, dining with Mailer and Random House editors. Six weeks later, after a restaurant employee denied him toilet access, Abbott stabbed aspiring actor Richard Adan to death, then told police Adan would never have made it as an actor.
At the end of the conference, Ronson drove Hare to Cardiff. On the way, they passed an overturned car. Ronson initially worried he was a psychopath because he had no instinct to stop and help the victim, but soon realized his shock at witnessing the incident was affecting his driving. Hare explained that Ronson’s amygdala was functioning normally, unlike psychopaths.
Ronson and Hare then mused on the intersection of psychopathy and power. Hare told Ronson he should have studied the Stock Exchange alongside prisons—asserting that serial killers ruin families, but corporate and political “psychopaths” ruin economies and societies. Ronson cites Harvard’s Martha Stout on the matter; she asserted that psychopaths gravitate toward power, advising partners to leave them because they do not experience hurt feelings and only seek to win. She reassures readers that worrying about being a psychopath means you aren’t one.
Interested in understanding more about his own mental state, Ronson visited Adam Perkins, a neuroscientist at the Institute of Psychiatry. During the meeting, Perkins administered anxiety tests on Ronson using painful shocks, and confirmed that Ronson scored above average. However, Perkins warned him to be careful as he continued his research, recounting a 19-year-old female history student who admitted sadistic urges and showed sexual reward responses to gory images. She tried joining the RAF to kill legally but was rejected. Perkins could not report her because his participants were anonymous.
Ronson muses on his investigation and what he learned from Hare. Hare argued that powerful psychopaths hide early antisocial histories and urged Ronson to investigate CEOs and politicians, saying it could change how people see the world. Ronson’s desire to uncover this outweighs his anxieties. He resolves to take his psychopath-spotting skills into the corridors of power.
The structure of these chapters contrasts the idealistic, experimental treatment of mental illness with the clinical, punitive framework of modern diagnostics—developing the theme of Labels as Instruments of Power. Chapter 3 details Elliott Barker’s LSD-fueled Total Encounter Capsule, designed to cure criminal patients by breaking down emotional barriers through marathon nude therapy sessions. In Chapter 4, Ronson shifts to Bob Hare’s PCL-R Checklist, which dismisses rehabilitation entirely in favor of strict behavioral detection and labeling. Via this juxtaposition, Ronson highlights a historical shift in psychiatric philosophy, moving from the humanistic radicalism of the 1960s to a rigid, structural categorization. Barker’s method assumes a buried humanity that can be excavated through shared vulnerability, while Hare’s approach treats psychopathy as a permanent, neurological deficit. The catastrophic failure of Barker’s program, evidenced by an 80% recidivism rate, paves the way for Hare’s checklist to dominate the field. Consequently, Ronson underscores how the psychiatric establishment’s understanding of extreme behavior evolves from attempting to heal the individual to protecting society through relentless categorization.
Within these clinical settings, Ronson transforms the concept of empathy from a tool of healing into a mechanism for manipulation. At the Oak Ridge hospital, patients participated in intensive group therapy to foster emotional connection, but the outcome actively worsened their conditions. Serial child-killer Peter Woodcock murdered a fellow patient immediately upon release, later admitting that the therapeutic environment taught him how to manipulate his psychiatrists and “keep the more outrageous feelings under wraps better” (88). Hare echoes this danger, warning that teaching empathy to individuals who lack it merely provides them with an empathy-faking finishing school. Instead of internalizing moral restraint, psychopathic patients weaponized the vulnerability of therapeutic language. Through these case studies, Ronson dismantles the assumption that emotional openness universally yields positive results. Barker’s unconventional therapy, for example, taught psychopathic subjects to mirror their typically-brained counterparts—mirroring expected neurotypical responses enabled these subjects to exploit the very system designed to cure them, suggesting that applying standard psychiatric frameworks to anomalous profiles equips dangerous individuals with better camouflage.
The text examines the shifting dynamics of power between the observer and the observed, emphasizing how the act of diagnosis empowers the diagnostician and furthering the theme of The Allure and Risk of Armchair Diagnosis. Barker observes his subjects through a one-way mirror, maintaining a detached authority over their hallucinogenic experiences. Similarly, Hare instructs his attendees on how to decode subtle intimidation tactics, such as a subject moving a chair beneath a panic button. Ronson himself experiences a palpable shift during the Hare training, noting, “I was attaining a new power, like a secret weapon” (104), as he fantasizes about applying his new diagnostic skills against personal critics. Ronson thus suggests that diagnosis operates as a form of control, establishing a hierarchy where the trained observer claims to see a truth invisible to the layperson. Ronson’s own transition from a skeptical journalist to a convinced spotter of pathology mirrors the seductive nature of psychiatric authority. The ability to categorize human behavior into a quantifiable 20-point checklist offers the illusion of mastery over chaos, revealing how the pursuit of psychological truth is often entangled with a desire for interpersonal power.
Using detailed descriptions of prominent psychiatrists' work alongside personal anecdotes, Ronson frames morality and conscience as measurable physiological functions instead of abstract philosophical concepts. For example, Hare’s experiments measure anticipation and fear using electric shocks and grotesque images to categorically prove that psychopaths’ brains function differently—in this case, the amygdala does not function. Later, when Ronson drives past an overturned car, he experiences a visceral, physical reaction, which Hare explains evidences Ronson’s central nervous system and amygdala communicating distress—a neurological process “that psychopaths are incapable of experiencing” (109). By anchoring the vague notion of “madness” within tangible physiological experiences Ronson shifts psychopathy from a moral failing to a structural brain anomaly. Ronson’s physiological reaction to the car crash validates his neurotypicality while simultaneously underscoring the atypical nature of the psychopathic brain. This biological determinism complicates traditional notions of justice and blame; if empathy is merely the result of a functioning amygdala, Ronson suggests, the chaotic and violent actions of individuals like Jack Henry Abbott are inevitable biological outputs rather than conscious moral choices.
Ronson’s experiences at Hare’s conference and reflections on his work expand the scope of psychopathy from individual deviance to systemic, institutional dominance. Hare expresses regret that his research was confined to prisons, arguing that corporate, political, and religious psychopaths ruin economies and societies. Harvard psychologist Martha Stout reinforces this theory, asserting that individuals devoid of empathy naturally gravitate toward the top of societal hierarchies because they are unburdened by conscience and driven solely by the will to win. Leaning on Hare’s and Stout’s theories, Ronson reframes the core investigation of his text. Rather than an isolated anomaly found in high-security hospitals, he begins to question if psychopathy is a driving force behind global political and economic structures. He holds that the traits identified on the PCL-R Checklist—such as glibness, grandiosity, and a lack of remorse—align closely with the characteristics rewarded in capitalist and political arenas. By suggesting that society is organized and manipulated by those at the extreme edges of psychological deviation, the text forces a reevaluation of modern leadership, positioning systemic inequality as the direct result of unchecked pathology.
