This book explores what it means to be a twin and to what extent twins can shape or 'escape' their identities as twins. It investigates how social expectations about twins shape twins' lives and how twins utilize their bodies, space and talk to actively display and perform their own identities.

This book draws on nearly one thousand cases and anecdotes about twins bending and breaking rules in order to fulfill or flout tenets of twinhood. Society’s unwillingness to contextualize mores and policies to suit twins may perpetuate controversy and law-breaking. Twins and Deviance shows how twins’ allegedly sacred bond violates conventions beginning at conception. Throughout their lives, they may be victimized, tortured, and neglected specifically because of their bond. Twins have lives that matter – their bond is not static or unconditional, it may be fluent and emotional. The book paints a picture of twin individuals whose lives relate to contemporary readers’ and audiences’ lives because they are weird, eccentric, ritualized, fetishized, pornographized, criminalized, and chastised by society; but what is especially interesting about twins is that society has institutionalized controversial practices and traditions sometimes implicitly or explicitly demanding that twinhood be realized or dishonored so that twins comply with social norms and expectations. Offering a truculent, unpretentious, and straightforward representation of contemporary society, Twins and Deviance does not defend or defy society’s strange, niche, and shaded view of twins. Rather, it artfully and sensitively depicts twins as historically and presently seeming like gods, heroes, renegades, saviors, mutations, terrorists, gangs, and betrayers; and skillfully discusses twins’ bodies to elucidate their individuality, decode their correspondence, and explore analytical tributaries new to sociocultural research. Using vivid examples, Twins and Deviance postulates that twins intrigue and entrance singletons because they deviate from norms, embody principles of duality, fulfill self-reflexive fantasies, and symbolize eternal life and the afterlife. The value of twins and twinhood to singletons is evident in psychoanalysis, reflections, religion and mythology, words, and politics; and yet, this is the only book to bring to light the immense depth of this captivating insight. Twins and Deviance challenges and improves previous research by collecting new topics to retool twins and deviance discussions. As such, it is a must-read for students, professors, and audiences engaging in gender, justice, sexuality, legal, and cultural studies, and all researchers conducting twin studies.

A 2022 Choice Reviews Outstanding Academic Title Takes the first in-depth look at the New York City adoption agency that separated twins and triplets in the 1960s, and the controversial and disturbing study that tracked the children’s development while never telling their adoptive parents that they were raising a “singleton twin.” In the early 1960s, the head of a prominent New York City Child Development Center and a psychiatrist from Columbia University launched a study designed to track the development of twins and triplets given up for adoption and raised by different families. The controversial and disturbing catch? None of the adoptive parents had been told that they were raising a twin—the study’s investigators insisted that the separation be kept secret. Here, Nancy Segal reveals the inside stories of the agency that separated the twins, and the collaborating psychiatrists who, along with their cadre of colleagues, observed the twins until they turned twelve. This study, far outside the mainstream of scientific twin research, was not widely known to scholars or the general public until it caught the attention of documentary filmmakers whose recent films, Three Identical Strangers and The Twinning Reaction,left viewers shocked, angered, saddened and wanting to know more. Interviews with colleagues, friends and family members of the agency’s psychiatric consultant and the study’s principal investigator, as well as a former agency administrator, research assistants, journalists, ethicists, attorneys, and—most importantly--the twins and their families who were unwitting participants in this controversial study, are riveting. Through records, letters and other documents, Segal further discloses the investigators’ attempts to engage other agencies in separating twins, their efforts to avoid media exposure, their worries over informed consent issues in the 1970s and the steps taken toward avoiding lawsuits while hoping to enjoy the fruits of publication. Segal's spellbinding stories of the twins’ separation, loss and reunion offers readers the behind-the-scenes details that, until now, have been lost to the archives of history.

A leading expert on twins delves into the stories behind her research to reveal the profound joys and real-life traumas of 12 remarkable sets of twins, triplets, and quadruplets. Segal unravels these moving stories with an eye for the challenges that life as a twin (or triplet or quadruplet) can pose to parents, friends, and spouses, as well as the twins themselves.

Exploring Twins presents an analysis of twinship considered as a specifically social phenomenom. Drawing upon a wide range of interdisciplinary, historical, and cross-cultural data, Elizabeth Stewart argues that in both traditional and modern societies, twinship represents a recurrent anomaly that calls into question the assumptions around which different types of society are organized.

Twins Talk is an ethnographic study of identical twins in the United States, a study unique in that it considers what twins have to say about themselves, instead of what researchers have written about them. It presents, in the first person, the grounded and practical experiences of twins as they engage, both individually and together, the “who am I” and “who are we” questions of life. Here, the twins themselves are the stars. Dona Lee Davis conducted conversational interviews with twenty-two sets of identical twins attending the Twins Days Festival in Twinsburg, Ohio, the largest such gathering in the world. Lively and often opinionated, each twin comes through as a whole person who at the same time maintains a special bond that the vast majority of people will never experience. The study provides a distinctive and enlightening insider’s challenge to the nature/nurture debates that dominate contemporary research on twins. The author, herself an identical twin, draws on aspects of her own life to inform her analysis of the data throughout the text. Each chapter addresses a different theme from multiple viewpoints, including those of popular science writers, scientific researchers, and singletons, as well as those of the twins themselves.

Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins sheds new light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins.

The Minnesota Study of Twins Reared Apart startled scientists by demonstrating that twins reared apart are as alike, across a number of personality traits and other measures, as those raised together, suggesting that genetic influence is pervasive. Segal offers an overview of the study’s scientific contributions and effect on public consciousness.

"A unique window into human behavior and development." —Steven Pinker The riveting story of two sets of identical twins separated at birth and improbably reunited as adults, a dream case for exploring nature and nurture. Accidental Brothers tells the unique story of two sets of identical Colombian twin brothers who discovered at age 25 that they were mistakenly raised as fraternal twins—when they were not even biological brothers. Due to an oversight that presumably occurred in the hospital nursery, one twin in each pair was switched with a twin in the other pair. The result was two sets of unrelated “fraternal” twins—Jorge and Carlos, who were raised in the lively city of Bogotá; and William and Wilber, who were raised in the remote rural village of La Paz, 150 miles away. Their parents and siblings were aware of the enormous physical and behavioral differences between the members of each set, but never doubted that the two belonged in their biological families. Everyone’s life unraveled when one of the twins—William—was mistaken by a young woman for his real identical twin, Jorge. Her “discovery” led to the truth—that the alleged twins were not twins at all, but rather unrelated individuals who ended up with the wrong families. Blending great science and human interest, Accidental Brothers by Nancy L. Segal and Yesika S. Montoya will inform and entertain anyone interested in how twin studies illuminate the origins of human behavior, as well as mother-infant identification and the chance events that can have profound consequences on our lives.
