What Kübler-Ross Actually Said

Elisabeth Kübler-Ross published "On Death and Dying" in 1969 based on interviews she conducted with terminally ill patients at a Chicago hospital. The five stages — denial, anger, bargaining, depression, acceptance — emerged from those conversations as descriptive categories for experiences she observed. She was describing what she heard, not prescribing a sequence that grief must follow. This is not a subtle distinction. Kübler-Ross herself spent decades of her later career clarifying that the stages were never meant to be a linear progression, never meant to apply universally, and never meant to tell grieving people what they should be experiencing. In her final book, co-authored with David Kessler, she wrote explicitly that the stages can occur in any order, can be skipped entirely, and can repeat. None of this corrected the popular understanding.

How the Stages Became a Checklist

The model was simple, memorable, and provided structure to an experience that is fundamentally structureless. Grief is chaotic. It returns without warning. It shifts between states without logic. The stages offered an explanatory framework that felt like a map. Medical training integrated the model. Hospital social workers learned it. Hospice care programs built it into their educational materials. By the time grief counseling became a recognized field, the stages were foundational — not because the evidence behind them was particularly strong (the original work was qualitative interview research, not a controlled study), but because nothing else had offered as clear a framework. The cultural installation was complete when the model moved beyond terminal illness into any significant loss. Job loss, divorce, the end of friendship — all could now be processed through the five stages. The framework expanded to fill whatever container it was placed in.

What the Research on Grief Actually Shows

Studies on bereaved populations conducted after Kübler-Ross published her framework tell a different story. A large study from Columbia University and Yale's Center for Anxiety and Traumatic Stress following bereaved adults over several years found that the most common trajectory of grief was not the progression through five stages but rather what researchers described as "resilience" — most people did not experience prolonged, debilitating grief, and a significant portion showed relatively stable functioning throughout bereavement. The study also found that depression was not universal and was not a necessary stage of grief. Many people moved through loss without a period of significant depression. The assumption that depression must occur, and that skipping it represents incomplete grieving, had no empirical support. Research from the University of Utrecht examining the stages specifically found that many bereaved people experienced stages simultaneously or in reverse order, and that the absence of anger or bargaining did not predict worse long-term outcomes. The stages, in other words, were neither universal nor sequential nor predictive of recovery.

A Tangent: The Prolonged Grief Question

One of the more consequential developments in grief research has been the identification of what is now called Prolonged Grief Disorder — a condition in which grief does not follow the typical trajectory of gradually lessening intensity over time, but instead remains acute and debilitating long after the loss. This is now a clinical diagnosis with evidence-based treatment options. The existence of prolonged grief as a distinct condition complicates the stages model in an important way: if the stage model were accurate, everyone would pass through a difficult period and emerge; the fact that some people don't, and that this requires specific clinical attention, suggests grief is not a universal process with a predictable endpoint. What happens instead is highly variable and depends on the nature of the loss, the person's attachment style and prior experiences, social support, and other factors the stages model doesn't account for.

What Kessler Added

David Kessler, who co-authored the revised edition with Kübler-Ross and has spent decades working in grief, later proposed a sixth stage: finding meaning. This addition was not about making the model more accurate as an empirical description of how grief proceeds — it was about offering a framework for what some people who navigate loss well eventually describe doing. Even this extension illustrates the problem. Adding stages is intuitive because the model feels like it should be comprehensive. But grief is not a process that moves through stages toward completion. Research from Harvard Medical School tracking bereaved spouses found that grief tended to ebb and flow over years, with unexpected triggers producing waves of acute loss long after overall adaptation had occurred. There is no final stage. There is adjustment, and periodic return. Kübler-Ross changed how medicine talks about death and dying, and that contribution was significant. The specific model should be used more carefully than it is — as one possible lens among several, not as the structure grief is supposed to follow.
