Apathy (also called perfunctoriness) is a lack of feeling, emotion, interest, and concern. Apathy is a state of indifference, or the suppression of emotions such as concern, excitement, motivation, and/or passion. An apathetic individual has an absence of interest in or concern about emotional, social, spiritual, philosophical and/or physical life and the world.The apathetic may lack a sense of purpose or meaning in their life. An apathetic person may also exhibit insensibility or sluggishness. In positive psychology, apathy is described as a result of the individual feeling they do not possess the level of skill required to confront a challenge (i.e. "Flow"). It may also be a result of perceiving no challenge at all (e.g. the challenge is irrelevant to them, or conversely, they have learned helplessness). Apathy may be a sign of more specific mental problems such as schizophrenia or dementia. However, apathy is something that all people face in some capacity. It is a natural response to disappointment, dejection, and stress. As a response, apathy is a way to forget about these negative feelings. This type of common apathy is usually only felt in the short-term and when it becomes a long-term or even lifelong state is when deeper social and psychological issues are most likely present.
