Sometimes we do not want to move. 
Sometimes we do not want to move. We may want to stay still. This can happen even if we can act. 
Some people call this being lazy. They might use names like "slacker." This can happen when we lack interest. It can also happen when we lack confidence.
In school, some students say they are lazy. Teachers might think they just cannot do the work. Sometimes, our brains just feel very tired.
Even animals do this! Many animals eat food and then rest. They do not need to be busy all day. They find enough food and then stay still.
It is okay to take a break. Do you like to rest too?
Laziness is when a person does not want to act. This happens even if they are able to do the work. People often use mean words for this. They might use names like "slacker" or "couch potato." 
In 1931, a study looked at high school students. Many students said they failed because of laziness. However, teachers thought it was because students lacked ability.
Laziness can happen for many reasons. It might come from low self-esteem. It can also come from a lack of interest. Sometimes, it is caused by too many distractions. These distractions can change how the brain works. They can increase dopamine. Dopamine is a chemical that brings pleasure. Too much of it can make it hard to value hard work.
Even animals show this behavior. Most animals eat until they are full. Then, they spend much of their time doing nothing. They do not try to find the perfect food. They just find enough to stay healthy. Some predators are very good at hunting. Because they are so fast, they have more free time. This can make them look lazy to others.
Laziness is a feeling where someone does not want to work or be active. This happens even when the person has the ability to do things. People sometimes use mean words to describe this, like "slacker" or "couch potato." 
There are many ways laziness might work in the brain. It can start with a lack of interest or low self-confidence. Sometimes, too many distractions can cause a problem. These distractions increase a chemical called dopamine. Dopamine is a messenger in the brain that brings pleasure and reward. If there is too much dopamine, a person might find it hard to value productive work. This can change how the brain perceives risks or handles tasks.
People have studied this topic for a long time. In 1931, a survey looked at high school students. The students said they failed because of laziness. However, teachers thought a lack of ability was the main cause. In 1954, Leonard Carmichael noted something interesting about psychology books. He saw that the word "laziness" was not in most technical tables of contents. This shows that experts view the topic in very specific ways.
Different thinkers have many ideas about why people stay idle. An economist named Frédéric Bastiat argued that people focus on quick pleasure. They might choose immediate fun over better long-term results. Ludwig von Mises said that working can feel like a loss of satisfaction. Because of this, people prefer leisure time whenever they can get it. Even hard-working people in history worked hard just to reach a state of rest. 
Even animals show behaviors that look like laziness. Most animals forage for food until they are full. After that, they spend much of their time doing nothing at all. They do not always look for the perfect food or home. They simply find enough to meet their needs. Some predators are so good at hunting that they have lots of free time. This can make them look much lazier than animals that struggle to find food. 
Laziness, often called indolence or sloth, is an emotional disinclination toward activity or exertion. This occurs even when a person possesses the actual ability to act or exert themselves. While it is frequently used as a pejorative term, it is distinct from certain medical conditions. For example, it should not be confused with avolition. Avolition is a negative symptom seen in neurodevelopmental disorders like ADHD, ASD, or schizophrenia. Laziness is also different from lethargy, which is a state of lacking energy, or abulia, a medical term for reduced motivation. 
Psychological studies suggest several mechanisms that cause laziness to manifest. It may reflect a lack of self-esteem or a lack of discipline caused by low self-confidence. It can also stem from a lack of interest in a specific activity. One theory involves the release of dopamine, a neurotransmitter responsible for reward and pleasure. Over-stimulation or excessive distractions can increase dopamine levels. This increase can lead to desensitization, making a person less able to value productive actions. This process can negatively affect the anterior insula, a part of the brain responsible for risk perception.
Laziness can manifest in several distinct ways, such as procrastination or vacillation. In some cases, it acts as a negative coping mechanism known as aversion. This is a desire to avoid certain situations to counter specific experiences or preconceived bad results. Researchers Thomas Goetz and John Eastwood suggest these aversive states can be adaptive for making change. However, they can also become toxic if they are allowed to fester. They recommend being mindful of these states rather than simply looking for ways to escape them. They also note that constant activity without breaks can cause oscillations of failure that impact mental health.
History shows that different groups have viewed laziness through various lenses. In a 1931 survey, high school students often blamed their failing performance on laziness. However, teachers in that same survey ranked "lack of ability" as the primary cause, with laziness coming in second. In 1954, Leonard Carmichael observed that "laziness" was rarely found in the tables of contents of technical psychology books. This suggests that while the behavior is common, it is often categorized under more technical terms in scientific literature. Religious traditions have also categorized it for centuries. In Catholicism, sloth is one of the seven deadly sins. In Buddhism, the term kausīdya refers to spiritual sloth or clinging to unwholesome activities.
Economists offer specific perspectives on why humans exhibit idle behavior. Frédéric Bastiat argued that idleness results from people focusing on pleasant immediate effects. They may prioritize these over more positive long-term consequences. Ludwig von Mises suggested that the expenditure of labor is viewed as painful. He argued that people prefer leisure over travail, or hard work. People will only work when they value the return of that labor more than the loss of leisure. Interestingly, Hal Cranmer noted that humans work very hard specifically to achieve leisure time. Even historical Puritans worked hard to reach an eternity of resting on a cloud.
Literature has long explored the social and spiritual consequences of idleness. In the 1700s, writers like David Bertelson argued for "spiritual industry" over "patriotic industry." Thomas Jefferson noted that in the rise of slave-holding society, some people experienced a rise in indolence. By the 1800s, the Romantic movement changed these views by making idleness seem glamorous. John Pendleton Kennedy wrote about idleness as being in oneness with nature. Later, Mark Twain used the character of Huckleberry Finn to contrast realist and romantic views of aimlessness. In the 20th century, authors like Flannery O'Connor used the concept to depict spiritual backwardness.
Even in the animal kingdom, behaviors resembling laziness are common. Most animals follow a pattern of foraging for food until they are satiated. Once they have met their needs, they spend much of their time doing nothing in particular. This is known as trying to "satisfice" rather than seeking an optimal diet or habitat. Even diurnal animals, which are active during the day, follow this pattern. Interestingly, extremely efficient predators often have more free time. This can make them appear much lazier than inept predators that must spend all their time searching for food. Some animals, like beetles, also appear to forage lazily due to a lack of competitors.
