The popular idea that terminally ill and bereaved people go through predictable stages, such as denial, anger, and so forth "is not supposed by research studies".

The five stages of dying are; denial, anger, bargaining, depression, acceptance. These stages start when the patient is first known of a terminal ailment. While Kubler-Ross trusted this to be general, there is a considerable amount of space for singular variety. Not every person experiences each stage and the order of the stages might be distinctive for every individual.

This idea is not supported by research studies.

Research studies have found that Kubler-Ross's theory that grieving individuals go thorough predictable stages of grief has not been corroborated by further research. Instead research on grief and bereavement has found that different individuals cope with death differently, and might experience some of Kubler-Ross's stages (denial, anger, etc.), but not in a fixed order.
