There are five stages of grief in the most widely known model: denial, anger, bargaining, depression, and acceptance. This framework comes from psychiatrist Elisabeth Kübler-Ross, who first described it in her 1969 book On Death and Dying. But while these five stages are deeply embedded in popular culture, the science behind them is surprisingly thin, and most grief researchers today consider the model outdated or incomplete.
The Five Stages, Explained
Kübler-Ross developed her model after spending years interviewing terminally ill patients. She originally intended the stages to describe what dying people themselves experience, not what their surviving loved ones go through. Over time, the framework was adopted more broadly to describe bereavement of all kinds.
The five stages are:
- Denial: A sense of disbelief or numbness that buffers the initial shock.
- Anger: Frustration directed at the situation, at other people, or even at the person who died.
- Bargaining: “What if” thinking, replaying events and imagining how things could have gone differently.
- Depression: Deep sadness as the full weight of the loss sets in.
- Acceptance: Not necessarily feeling “okay,” but acknowledging the reality of the loss and beginning to adapt.
Even Kübler-Ross herself later clarified that these stages are “not stops on some linear timeline in grief” and that not everyone goes through all of them or experiences them in order.
Why Many Experts Disagree With the Model
The five stages were never built on rigorous research. They came from a collection of case studies and bedside conversations, not from controlled studies tracking how people actually grieve over time. Researchers at McGill University’s Office for Science and Society have described the model as “not science-based” and note that it “does not well describe most people’s experiences.”
When researchers have tested the model, the results haven’t supported it. A 1981 study of 193 widowed individuals found no evidence of separate stages of adaptation. A later study by psychologist George Bonanno tracked 205 people before and after a spouse’s death and found that only 11% followed the grief trajectory the stage model assumes is “normal.”
The bigger concern is that a descriptive idea became prescriptive. People who don’t experience anger, or who skip straight to acceptance, can feel like they’re grieving “wrong.” In reality, there is no set pattern of emotions that must be experienced to come to terms with a loss.
Alternative Frameworks That Fit Better
Several models have emerged that reflect how grief actually works for most people.
Worden’s Four Tasks of Mourning
Psychologist William Worden reframed grief not as stages you pass through passively, but as four active tasks. The first is accepting the reality of the loss, which can take months or years as the truth sinks in during moments the person would have been present for. The second is processing the pain, emotionally, physically, and spiritually. The third is adjusting to a world without the person, which includes practical changes like taking on new responsibilities, internal shifts in identity, and spiritual questions about meaning. The fourth is finding a way to maintain a connection to the deceased while moving forward with life. These tasks don’t follow a set order. People move back and forth between them over time.
The Dual Process Model
Developed by researchers Margaret Stroebe and Henk Schut, this model describes grief as an oscillation between two types of coping. One is loss-oriented: sitting with sadness, longing, and the pain of what happened. The other is restoration-oriented: handling the practical, even mundane, changes that follow a death, like learning to manage household tasks alone or building new relationships. Healthy grieving involves moving between these two modes rather than staying stuck in either one. This model has gained enough clinical support that it now forms the basis for treatments used in complicated grief cases.
What Grief Feels Like in the Body
Grief isn’t just emotional. The stress response it triggers raises your heart rate, blood pressure, and breathing rate while flooding the body with stress hormones. A 2014 study in JAMA Internal Medicine found that within 30 days of a partner’s death, people 60 and older had more than twice the risk of a stroke or heart attack compared to those who hadn’t experienced such a loss. Research published in the American Heart Association journal Circulation showed the danger was highest in the first 24 hours. Grief has also been linked to disrupted sleep, immune system changes, and increased risk of blood clots.
How Long Grief Typically Lasts
There’s no universal timeline, but for most people, the most intense symptoms of grief, the numbness, the waves of sorrow, the difficulty functioning, gradually ease over the first several months. That doesn’t mean grief disappears. It means the acute, overwhelming quality of it softens enough that daily life becomes manageable again.
For roughly 7 to 10% of bereaved people, grief doesn’t follow this trajectory. Instead, it intensifies or remains at the same overwhelming level. The American Psychiatric Association now recognizes this as prolonged grief disorder, a formal diagnosis added to the diagnostic manual in 2022. To qualify, the loss must have occurred at least a year ago for adults (six months for children), and the person must experience at least three specific symptoms nearly every day for the prior month. These include feeling as though part of yourself has died, a sense that life is meaningless without the person, and intense loneliness or detachment from others.
How Culture Shapes the Grieving Process
The five-stage model reflects a particular Western, clinical lens. Grief looks and feels different across cultures. Some Chinese communities observe a 100-day mourning period. Some Aboriginal peoples express sorrow through physical acts like cutting across the arm or chest. In some cultures, mourning means wearing black; in others, white. These aren’t just surface differences in customs. The inner emotional experience of grief itself varies between cultural groups, and feelings of loss are often so deeply tied to early life that they can only be expressed in the language of one’s childhood.
No single model captures every person’s experience. The five stages remain a useful shorthand for naming some of the emotions grief can bring, but they were never a roadmap, and treating them as one can do more harm than good. Grief is less like climbing a staircase and more like weather: unpredictable, sometimes calm, sometimes overwhelming, and always personal.
