"[Denworth] has a solid command of the complex material before her and a seemingly effortless ability to make it not just digestible but engaging.… [She] sticks to the science, calmly telling us the truth no matter what we think we need to hear. What else are friends for?"
Wall Street Journal - Daniel Akst
"A mind-blowing book about the science and power of friendship."
Armchair Expert - Dax Shepard
Science writer Denworth takes a broad look at the origins and functions of friendship in her intriguing debut. Her focus ranges from animal behavior to neurobiology and from sociology to psychology and physiology. After speaking with many leading researchers, Denworth draws several striking conclusions—notably that, having been found in an extensive variety of species, friendship has deep evolutionary roots. This helps explain the large panoply of positive health benefits associated with friendship and, inversely, the dire medical consequences she reports as sometimes arising from loneliness. Denworth also examines the impact of virtual relationships and the increased use of technology by different generations, concluding that research demonstrates no net benefit or harm from social media use: “Friendship, real friendship, hasn’t changed much. It is alive and well, even thriving.” Her reporting is peppered with personal asides about how she and her family members have navigated various relationships. While this enlivens her work’s more technical facets, it does potentially give the impression of putting anecdotal experiences on a par with evidence-based studies, thus undercutting the importance of the latter. Science enthusiasts may find Denworth’s survey wider than it is deep, but it does provide an effective introduction to its subject.
"Accessible and enlightening...By highlighting the importance of human connection, Denworth has crafted a worthy call to action."
Washington Post - Barbara King
"The power of friendship—in many ways the most essential of our relationships—has long been underestimated. It's an absolute pleasure to see Lydia Denworth do it justice in this lovely, insightful, and important book."
"I can think of no better rebuke to today’s success-obsessed brand of parenting than Denworth’s clarion call for friendship. Her convincing narration of the science shows that for our kids to live happily ever after, and successfully too, we must let them spend many more afternoons with friends."
"The science of friendship has grown remarkably rich in recent years, with scientists studying everything from the chemicals that create bonds in our brains to the friendships animals make for years on end. There's a deep evolutionary story to friendship now, and Lydia Denworth tells it in clear, lyrical prose."
"A sweeping, precise, and engaging narrative about our primordial capacity for friendship. If you care about what really matters in life, read this fantastic natural history of human friendship."
"Friendship was once mocked as a naive notion, irrelevant in our species and nonexistent in others. In her lively, personable style, Lydia Denworth reviews what we know about the benefits of close relationships and their long evolutionary history"
"Critical and convincing... Denworth’s work achieves the best of science writing by making complicated concepts clear. She uses intelligent observation, empathy, and curiosity to offer a friendship manifesto that will absolutely affect readers' own personal approaches to friendship."
Booklist (starred review)
(I Can Hear You Whisper) argues that humans are wired for friendship, and that in order to thrive we have a biological need for connection. In a personable and accessible style, Denworth lays out her argument, exploring the biological underpinnings and the evolutionary history of friendship. Denworth takes readers along with her as she travels to the island of Cayo Santiago off the coast of Puerto Rico to learn about the complex social dynamics of rhesus macaque monkeys and to Los Angeles, where she spends time with older adults participating in Generation Xchange, a loneliness intervention program that pairs older adults with elementary school classrooms. In between, Denworth writes about the work of many scientists and their numerous studies, covering topics such as the connection between social relationships and mortality and the evolutionary advantage that friendship provides, all the while peppering her writing with tales of her own children and their friendships. VERDICT After reading Denworth's treatise on friendship, you may want to immediately call your best friend, or make a new one. Recommended for fans of human biology and nonfiction browsers. —Ragan O'Malley, Saint Ann's Sch., Brooklyn
Exploring the science of friendship.
In the past few decades, friendship has become the target of studies by neuro- and social scientists who have established that seeking and building connections to others is essential for human survival. As
Scientific American contributing writer Denworth ( I Can Hear You Whisper: An Intimate Journey Through the Science of Sound and Language, 2014, etc.) notes, the science has its roots in the studies of the mother-infant bond as well as the animal behavior work of Konrad Lorenz and others, later field studies of chimpanzees, macaques, and other primates, and, more recently, the work of primatologist Frans de Waal. Their observations can now be complemented by advances in technology. For example, near-infrared spectroscopy has been used to show that a section of the brain of a 5-month-old infant lights up when the baby sees a video of a mother playing peekaboo but not when viewing, say, an animated toy. The evidence from brain scans, genetic studies, and other physiological data underscores how social connectivity has been built into our systems; we demonstrate a "need to belong." Denworth traces this need over the lifetime, discussing the behavior of toddlers, preteens, adolescents, and adults. Of special interest is a second major growth spurt in the brain that occurs during puberty and features rapid growth in the emotional sections of the brain. At this time, scans show that the mere presence of peers lights up reward areas of the brain—a possible spur to impulsivity and risk-taking. (Most teenage driving accidents happen when friends are in the car and not when the driver is alone.) The author also discusses social networks and social media (not likely to replace face-to-face friendships). In addition to examining the scientific underpinnings of friendship, Denworth capably demonstrates how loneliness, an increasing hazard as Americans age and lose friends and family, is truly a health- and life-threatening condition, and there are things to be done to avoid it.
Convincing evidence that evolution endowed us with a need for friends, support, comfort, stimulation, and, ultimately, happiness.
