Silent wounds: how intergenerational trauma persists through unspoken family histories

A personal essay explores how childhood silence around family tragedies, from 9/11 responders to Holocaust survivors, shapes inherited trauma and hinders healing until stories are finally told.

A new account of intergenerational trauma argues that what children inherit is often less the event itself than the silence around it. In a personal essay published by Slate, a cognitive neuroscientist links her own childhood confusion about family losses to her research on the children of 9/11 responders, suggesting that families often pass down fear, grief and omission in equal measure.

The writer recalls growing up with only fragments of her father’s past: a clipped answer about cousins, a sense that something had been broken, and an early encounter with Holocaust material that her mother thought she was too young to read. That private family history becomes the starting point for a broader investigation into whether trauma can shape the lives of the next generation, even when parents try to protect their children by keeping painful memories at a distance.

Her research focused on World Trade Centre responders who lived with post-traumatic stress disorder after working amid the devastation of the attacks. Studies of the cohort have found that the aftermath of 9/11 left a lasting mental health toll on many workers, and recent research on their families has examined whether that burden is reflected in the emotional health, relationships and quality of life of their adult children. In some cases, parents were willing to take part but hesitated to involve their offspring, suggesting that even decades later the attacks remain difficult to discuss openly.

That reluctance fits a wider pattern seen in studies of Holocaust survivors and their families. Earlier research on the children of survivors found themes of fear, mistrust, overidentification with parents’ suffering and a heightened awareness of the trauma that shaped the household, even when parents did not speak about it directly. At the same time, broader reviews have found that not every family shows the same pattern and that many survivors’ descendants display considerable resilience, with some studies finding no clear evidence of secondary or third-generation trauma.

The 9/11 aftermath has also remained a public policy story. The Atlantic recently revisited the long fight over toxic exposure at Ground Zero, while Axios reported that New York City had released more than 170,000 pages of records on Sept. 8, 2026, adding to claims that officials knew more about the air risks than they told the public. Against that backdrop, the writer’s conclusion is quieter but sharper: children often grow up sensing the shape of a wound before anyone names it, and families can begin to heal only when the silence is finally broken.
