Laziness

Laziness (also known as indolence or sloth) is disinclination to activity or exertion despite having the ability to act or to exert oneself. It is often used as a pejorative; terms for a person seen to be lazy include "couch potato", "slacker", and "bludger". Related concepts include sloth, a Christian sin, abulia, a medical term for reduced motivation, and lethargy, a state of lacking energy.

Despite the famed neurologist Sigmund Freud's discussion of the "pleasure principle", Leonard Carmichael noted in 1954 that "laziness" is not a word that appears in the table of contents of most technical books on psychology".^[1] A 1931 survey found high-school students more likely to attribute their failing performance to laziness, while teachers ranked "lack of ability" as the major cause, with laziness coming in second.^[2] Laziness should not be confused with avolition, a negative symptom of certain mental and neurodevelopmental disorders such as depression, ADHD, ASD, sleep disorders, substance use disorders and schizophrenia.^[3][4]
