Dr. Falk divides the 13 stigmas into two categories. Persons who are excluded because of a condition that they did not choose or over which they have little control may suffer from "existential stigma." Such conditions include mental illness, sexual identity, obesity, mental retardation, aging, marital status, and race (particularly for Native Americans). The second category, "achieved stigma," includes persons who have somehow contributed to their inclusion in a stigmatized group. Here Falk describes stigma associated with achievement, immigration, homelessness, prostitution, addiction (including alcoholism), and criminal conviction. Many of us fall into at least one of these categories and, with the inclusion of "resentment against achievement," no one seems to be exempt from membership of some stigmatized group.
