Are horrific experiences indelibly fixed in a victim’s memory? Or does the mind protect itself by banishing traumatic memories from consciousness? How victims remember trauma is the most controversial issue in psychology today, spilling out of consulting rooms and laboratories to capture headlines, rupture families, provoke legislative change, and influence criminal trials and civil suits. This book, by a clinician who is also a laboratory researcher, is the first comprehensive, balanced analysis of the clinical and scientific evidence bearing on this issue—and the first to provide definitive answers to the urgent questions at the heart of the controversy.

Synthesizing clinical case reports and the vast research literature on the effects of stress, suggestion, and trauma on memory, Richard McNally arrives at significant conclusions, first and foremost that traumatic experiences are indeed unforgettable. Though people sometimes do not think about disturbing experiences for long periods of time, traumatic events rarely slip from awareness for very long; furthermore, McNally reminds us, failure to think about traumas—such as early sexual abuse—must not be confused with amnesia or an inability to remember them. In fact, the evidence for repressed memories of trauma—or even for repression at all—is surprisingly weak.

A magisterial work of scholarship, panoramic in scope and nonpartisan throughout, this unfailingly lucid work will prove indispensable to anyone seeking to understand how people remember trauma.

According to a major health survey, nearly half of all Americans have been mentally ill at some point in their lives—more than a quarter in the last year. Can this be true? What exactly does it mean, anyway? What’s a disorder, and what’s just a struggle with real life?

This lucid and incisive book cuts through both professional jargon and polemical hot air, to describe the intense political and intellectual struggles over what counts as a “real” disorder, and what goes into the “DSM,” the psychiatric bible. Is schizophrenia a disorder? Absolutely. Is homosexuality? It was—till gay rights activists drove it out of the DSM a generation ago. What about new and controversial diagnoses? Is “social anxiety disorder” a way of saying that it’s sick to be shy, or “female sexual arousal disorder” that it’s sick to be tired?

An advisor to the DSM, but also a fierce critic of exaggerated overuse, McNally defends the careful approach of describing disorders by patterns of symptoms that can be seen, and illustrates how often the system medicalizes everyday emotional life.

Neuroscience, genetics, and evolutionary psychology may illuminate the biological bases of mental illness, but at this point, McNally argues, no science can draw a bright line between disorder and distress. In a pragmatic and humane conclusion, he offers questions for patients and professionals alike to help understand, and cope with, the sorrows and psychopathologies of everyday life.
