Maladaptivity is frequently used as an indicator of abnormality or mental dysfunction, since its assessment is relatively free from subjectivity. However, many behaviors considered moral can be apparently maladaptive, such as dissent or abstinence. In more common indicator of normality is medical – mental illness. Abnormality is a subjectively defined characteristic, assigned to those with rare or dysfunctional conditions. A moral is a one sentence remark made at the end of many childrens stories that expresses the intended meaning, or the moral message, of the tale. A mental illness is defined by the medical profession as a disorder of the brain that results in a disruption in a persons thinking, feeling, moods, and ability to relate to others and to work.
