“Brilliant. . . . An absorbing read and a potent lesson in moral behavior—both of rodents and of humans.”—Deborah Blum, Pulitzer Prize–winning author of The Poison Squad • “A fascinating read about an immensely influential scientist.”—Robert M. Sapolsky, author of the New York Times–bestseller Determined • “Stimulating scientific history. . . . Colorful accounts. . . . This fascinates.”—Publishers Weekly

A bizarre and compelling biography of a scientist and his work, using rodent cities to question the potential catastrophes of human overpopulation.
 
It was the strangest of experiments. What began as a utopian environment, where mice had sumptuous accommodations, had all the food and water they could want, and were free from disease and predators, turned into a mouse hell. Science writer and animal behaviorist Lee Alan Dugatkin introduces readers to the peculiar work of rodent researcher John Bumpass Calhoun. In this enthralling tale, Dugatkin shows how an ecologist-turned-psychologist-turned-futurist became a science rock star embedded in the culture of the 1960s and 1970s. As interest grew in his rodent cities, Calhoun was courted by city planners and his work was reflected in everything from Tom Wolfe’s hard-hitting writing to the children’s book Mrs. Frisby and the Rats of NIMH. He was invited to meetings with the Royal Society and the pope and taken seriously when he proposed a worldwide cybernetic brain—a decade before others made the internet a reality.

Readers see how Calhoun’s experiments—rodent apartment complexes like “Mouse Universe 25”—led to his concept of “behavioral sinks” with real effects on public policy discussions. Overpopulation in Calhoun’s mouse (and rat) complexes led to the loss of sex drive, the absence of maternal care, and a class of automatons that included “the beautiful ones,” who spent their time grooming themselves while shunning socialization. Calhoun—and those who followed his work—saw the collapse of this mouse population as a harbinger of the ill effects of an overpopulated human world.

Drawing on previously unpublished archival research and interviews with Calhoun’s family and former colleagues, Dugatkin offers a riveting account of an intriguing scientific figure. Considering Dr. Calhoun’s experiments, he explores the changing nature of scientific research and delves into what the study of animal behavior can teach us about ourselves.

Fatal Misconception is the disturbing story of our quest to remake humanity by policing national borders and breeding better people. As the population of the world doubled once, and then again, well-meaning people concluded that only population control could preserve the “quality of life.” This movement eventually spanned the globe and carried out a series of astonishing experiments, from banning Asian immigration to paying poor people to be sterilized.

Supported by affluent countries, foundations, and non-governmental organizations, the population control movement experimented with ways to limit population growth. But it had to contend with the Catholic Church’s ban on contraception and nationalist leaders who warned of “race suicide.” The ensuing struggle caused untold suffering for those caught in the middle—particularly women and children. It culminated in the horrors of sterilization camps in India and the one-child policy in China.

Matthew Connelly offers the first global history of a movement that changed how people regard their children and ultimately the face of humankind. It was the most ambitious social engineering project of the twentieth century, one that continues to alarm the global community. Though promoted as a way to lift people out of poverty—perhaps even to save the earth—family planning became a means to plan other people‘s families.

With its transnational scope and exhaustive research into such archives as Planned Parenthood and the newly opened Vatican Secret Archives, Connelly’s withering critique uncovers the cost inflicted by a humanitarian movement gone terribly awry and urges renewed commitment to the reproductive rights of all people.
