Yes—Ronson blends humor, suspense, and critical analysis to explore complex questions about sanity and societal norms.

It’s praised for challenging perceptions of mental illness and power.

The Hare Psychopathy Checklist is a 20-item diagnostic tool developed by psychologist Robert Hare to identify psychopathic traits, such as superficial charm and lack of empathy. Ronson examines its use in prisons, corporations, and mental health institutions, revealing controversies about its accuracy and ethical application.

No—Ronson highlights that many psychopaths thrive in corporate or political roles due to traits like charisma and ruthlessness. He interviews figures like former CEO Albert J. Dunlap, whom Fast Company labeled a psychopath, showing how non-criminal environments can reward manipulative behavior.

Ronson uses investigative journalism, blending interviews with psychologists, incarcerated individuals, and executives. His “faux-naïf” style allows subjects to reveal their perspectives organically, while he critiques the mental health industry’s power to label and stigmatize.

Ronson questions the Hare Checklist’s reliability, noting it can conflate impulsivity with calculated cruelty. He also critiques overdiagnosis, citing cases where labels like “psychopath” led to lifelong institutionalization without clear evidence. The book warns against reducing complex behaviors to a checklist.

Yes—Ronson explores the idea that psychopathic traits (e.g., charm, risk-taking) exist in milder forms across the population. This challenges the traditional view of psychopathy as a binary diagnosis, suggesting societal structures often reward such traits in business or politics.

Ronson interviewed individuals diagnosed as psychopaths, including Tony, a Broadmoor Hospital patient who claims he faked insanity to avoid prison. He also profiles leaders like Toto Constant, exploring how psychopathic traits manifest in different contexts.

The book critiques institutions like Broadmoor’s DSPD unit, where controversial diagnoses lead to indefinite detention. Ronson highlights conflicts between psychiatry’s diagnostic power and its potential for misuse, such as conflating criminal behavior with mental illness.

Ronson argues that society often conflates rationality with sanity, while psychopaths and institutions alike exploit vague definitions. The book questions whether “insanity” is a useful label, given its subjective application in criminal justice and corporate culture.

The book urges skepticism toward oversimplified mental health labels, emphasizing the ethical risks of tools like the Hare Checklist. Ronson concludes that psychopathy—and sanity itself—are fluid concepts shaped by power dynamics, not absolute truths.
