Pregnancy Loss May Be the Norm, Not the Exception, Says Leading Anthropologist

When most of us picture pregnancy, the story that comes to mind is almost cinematic: a positive test, a glowing ultrasound, a growing belly, and finally the miracle of a newborn. Yet, as Kate Clancy, an anthropologist at the University of Illinois Urbana‑Champaign, points out, that tidy narrative leaves out a very messy reality that has been part of human reproduction for ages.

In her freshly released book, Pregnancy Interrupted: The Science and Stories of How Pregnancies Really End, Clancy argues that loss—whether in the earliest weeks or later on—may actually be the rule rather than the exception. “We’ve trained ourselves to treat a full‑term pregnancy as the normal experience,” she told Newsweek. “Anything else is automatically seen as a deviation.” Instead of viewing miscarriages as rare tragedies, she suggests we think of them as built‑in checkpoints in a biological process that is, frankly, a bit like throwing spaghetti against a wall.

Human reproduction is riddled with “tests of viability.” From the moment an egg is released, countless potential embryos are produced, and most of them never make it past the first few hurdles. Some never even implant; others stall weeks later because of chromosomal errors or other hidden factors. Interestingly, recent research shows that embryos can sometimes “self‑correct,” shunting faulty cells into placental tissue while healthier cells continue to develop. This nuance reshapes how we talk about pre‑implantation testing and the predictions we make about a baby’s health.

For many who have suffered a miscarriage, guilt can be a heavy burden. Clancy emphasizes that science largely absolves individuals of blame. “A large percentage of pregnancy loss is inevitable,” she says. “Even the best‑behaved lifestyle can’t prevent it if the underlying biology or environment is hostile.” She flags factors such as infectious disease, pollutants, endocrine‑disrupting chemicals, and even intimate partner violence as contributors—issues that are largely out of a single person’s control and more about public health policy.

The book also pushes back against the old‑fashioned idea of “maternal‑fetal conflict,” the notion that a mother and her fetus are locked in an evolutionary tug‑of‑war. Clancy argues that the relationship is far more cooperative; both parties benefit from each other’s survival. This reframing can help shift the language we use—from “a parasite eating me” to a shared biological partnership.

One of the most poignant findings from Clancy’s interviews with people who have experienced miscarriage is how isolating the experience can feel. “It’s often a quiet, lonesome process,” she notes, underscoring the need for broader societal understanding and support.

Ultimately, Pregnancy Interrupted asks us to broaden our view of what “normal” pregnancy looks like, acknowledging loss as an integral—though painful—part of the human story.
