Hervey M. Cleckley

Hervey M. Cleckley is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hervey M. Cleckley rather than just read about it. In short: Hervey Milton Cleckley (September 7, 1903 – January 28, 1984) was an American psychiatrist and pioneer in the field of psychopathy. His book, The Mask of Sanity, originally published in 1941 and revised in new editions until the 1980s, provided the first clinical description of psychopathy.

Key takeaways

  • Hervey M. Cleckley belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hervey M. Cleckley to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hervey M. Cleckley from memory before moving on to harder problems.

Reference excerpt

Hervey Milton Cleckley (September 7, 1903 – January 28, 1984) was an American psychiatrist and pioneer in the field of psychopathy. His book, The Mask of Sanity, originally published in 1941 and revised in new editions until the 1980s, provided the first clinical description of psychopathy. He defined the term somewhat more broadly than it is understood today, as referring to somebody who behaves in a destructive manner despite lacking overt signs of psychosis or neurosis; this is reflected in the term "mask of sanity", derived from Cleckley's belief that a psychopath can appear normal and even engaging, but that the "mask" conceals a mental disorder. By the time of his death, Cleckley was better remembered for a vivid case study of a female patient, published as a book in 1956 and turned into a movie, The Three Faces of Eve, in 1957. His report of the case (re)popularized the diagnosis of multiple personality disorder in America. The concept of psychopathy continues to be influential through forming parts of the diagnosis of antisocial personality disorder, the Psychopathy Checklist, and public perception.

Life and career Cleckley was born in Augusta, Georgia, in the Southeastern United States. His parents were William and Cora Cleckley. His younger sister, Connor Cleckley, was schooled for some time in England (e.g. Headington School, Oxford) and later married and widowed by Aquilla J. Dyess, the only person ever to be granted America's highest awards for both civilian and military heroism (the Carnegie medal and, posthumously after World War II, the Medal of Honor). Cleckley graduated from the Academy of Richmond County high school in 1921, then graduated in 1924 summa cum laude with a Bachelor of Science degree in mathematics and science from the University of Georgia (UGA) in Athens, where he was a member of the varsity football and track and field teams. Cleckley won a Rhodes Scholarship to study at Oxford University, England, graduating in 1926 with a Bachelor of Arts. Cleckley then earned his M.D. from the University of Georgia Medical School (now known as the Medical College of Georgia) in Augusta in 1929. After several years of psychiatric practice in the Veterans Administration, he became professor of psychiatry and neurology at the Medical College of Georgia and, in 1937, the chief of psychiatry and neurology at University Hospital in Augusta. In 1955, Cleckley was appointed clinical professor of psychiatry and neurology at the medical college and became founding chairman of the Department of Psychiatry and Health Behavior. He served as a psychiatric consultant to the Veterans Administration Hospital in Augusta and the US Army Hospital at Camp Gordon. He was a member of the forensic committee of the Group for the Advancement of Psychiatry and a fellow of the American Board of Psychiatry and Neurology and the Society for Biological Psychiatry. He also worked in the private practice of psychiatry along with Corbett Thigpen and later also Benjamin Moss, Jere Chambers, and Seaborn McGarity. His first wife was Louise Martin; after her death, he married Emily Sheftall.

Psychopathy In 1941, Cleckley authored his magnum opus The Mask of Sanity: An Attempt to Clarify Some Issues About the So-Called Psychopathic Personality. This became a landmark in psychiatric case studies and was repeatedly reprinted in subsequent editions. Cleckley revised and expanded the work with each edition published; the second American edition published in 1950 he described as effectively a new book (Cleckley 1988, p.vii). The Mask of Sanity is distinguished by its central thesis, that the psychopath exhibits normal function according to standard psychiatric criteria, yet privately engages in destructive behavior. The book was intended to assist with the detection and diagnosis of the elusive psychopath for purposes of palliation and offered no cure for the condition itself. The idea of a master deceiver secretly possessed of no moral or ethical restraints, yet behaving in public with excellent function, electrified American society and led to heightened interest in both psychological introspection and the detection of hidden psychopaths in society at large, leading to a refinement of the word itself into what was perceived to be a less stigmatizing term, "sociopath".

Military application In the same year as he published The Mask of Sanity during World War II, Cleckley wrote an address warning: "In our present efforts to prepare for national defense no problem which confronts the examining boards for selective service is more pressing or more subtle than that of the so-called psychopathic personality". He argued such soldiers were likely to fail, be disorganized, and be a drain on time and resources. He recommended routinely checking for past encounters with law enforcement or drinking alcohol until incapacitated. In The Mask of Sanity, under a subsection entitled "Not as single spies but in battalions", and further detailed in the appendix, Cleckley describes a survey he and others conducted between 1937 and 1939 at a large federal Veterans Administration (VA) hospital on the southeastern seaboard, where he worked as one of the psychiatrists for the ex-servicemen who were mainly veterans of World War I. Cleckley critiques the "benign policy" of the VA of not diagnosing more psychopathic personalities due to giving the benefit of the doubt to issues such as neurasthenia, hysteria, psychasthenia, posttraumatic neuroses, or cerebral trauma from skull injuries and concussions. He concludes that psychopathic personalities have "records of the utmost folly and misery and idleness over many years" and if considering also the number in every community who are protected by relatives, "the prevalence of this disorder is seen to be appalling."

Worked examples

Example 1 — a first encounter with Hervey M. Cleckley

Start with the simplest possible case. Write down what Hervey M. Cleckley claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hervey M. Cleckley before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hervey M. Cleckley ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hervey M. Cleckley

In research
Hervey M. Cleckley appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hervey M. Cleckley in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hervey M. Cleckley is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1903 births, 1984 deaths, 20th-century American medical doctors, so understanding it makes those chapters shorter.
In everyday life
Look for Hervey M. Cleckley outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
