People think about what is right and wrong. 
Some thinkers ask if these rules are the same for everyone. Others think rules change from place to place. 
Many groups have their own ways to live. These ways can help a group stay safe. Some people feel more care for their own group.
Some say we feel things like guilt to help us work together. This helps humans live in a big world. Do you wonder how people decide what is good?
Morality is the study of right and wrong. 
Some thinkers ask if moral rules are facts. This idea is called moral realism. They believe some things are truly right or wrong. Others believe morality comes from feelings or ideas. This is called moral anti-realism.

Many people study ethics. Ethics is a branch of philosophy. It asks big questions about how we should live. Immanuel Kant was a famous thinker. He spoke about duty and rules.
Rules can change between different groups. This is often called moral relativism. What is okay in one place might be bad in another. However, some researchers found rules that most groups share. These include being brave and helping your family. Some think these rules help humans work together. This helps our species survive and grow.
Morality is a system used to judge how people act. It helps us decide if an action is moral or immoral. We also use it to look at character traits. Good traits are called virtues, like being honest. Bad traits are called vices, like being cruel. Some people are against morality, which is called immorality. Others may be unaware of moral rules, which is called amorality. 
Philosophers study these ideas through a branch called ethics. Many people use the words ethics and morality to mean the same thing. However, some thinkers use them differently. For example, some use ethics to talk about practical reasoning. They might use morality to talk about specific rules or duties. Immanuel Kant was a famous philosopher who studied these rules. He created an idea called the categorical imperative. This idea suggests you should only act on rules that could become universal laws. 
There are different ways to think about where morality comes from. Moral realism is the idea that moral facts are real and objective. This means some things are right or wrong regardless of what people think. On the other hand, moral anti-realism suggests that moral statements do not report objective facts. Some believe morality is just a way to express emotions. Others think it comes from the commands of a god. This is often called divine command theory.
Morality can also change depending on a person's culture. This idea is called moral relativism. It suggests that what is okay in one community might be wrong in another. For example, a 2014 study showed different views on topics like gambling or alcohol. However, some researchers found rules that seem to be the same everywhere. They found seven universal rules in many societies. These include helping your family and being brave. They also include returning favors and respecting property. 
Some scientists believe morality comes from how living things survive. This is linked to how groups evolve over time. Some thinkers say we developed emotions like empathy or guilt. These feelings help humans cooperate with each other. This cooperation helps the whole group stay safe. Other observers notice that people often favor their own "in-group." This can include family or people from the same nation. This behavior might have helped our ancestors pass on their genes. 
Morality is a doctrine or a system of moral conduct. It involves making evaluative judgments about agents and their actions. These judgments assess whether actions are moral or immoral. They also evaluate character traits as virtues or vices. For example, honesty is often seen as a virtue. Cruelty is often viewed as a vice. 
There are different ways to describe a person's relationship to these standards. Immorality is the active opposition to morality. This means a person actively opposes what is moral or immoral. Amorality is different from this active opposition. It refers to an unawareness of, indifference toward, or disbelief in moral principles. An amoral person may lack moral standards or restraints entirely.
Philosophers study these concepts through a branch called ethics. While many use the terms interchangeably, some thinkers make distinctions. Some use morality to describe systems based on duty and obligation. This approach is often linked to the philosopher Immanuel Kant. 
Scholars also distinguish between descriptive and normative morality. Descriptive morality refers to the actual values and codes of conduct found in a society. It looks at what a significant number of individuals accept as right or wrong. It does not claim that these values are objectively true. Instead, it studies the claims people make. Normative ethics is the study of what is actually right or wrong. This field explores whether morality is independent of cultural values.
In the study of meta-ethics, theories are divided into realism and anti-realism. Moral realism is the belief that there are true moral statements. These statements report objective moral facts. Realists argue that cultural norms do not define what is truly right. On the other hand, moral anti-realism holds that moral statements do not report objective facts. Some anti-realists believe moral sentences express emotions. Others, called non-cognitivists, believe they are commands. Some theories, like divine command theory, claim morality comes from a god. Others, like ideal observer theory, claim it comes from a perfectly rational being.
Morality also functions through different social structures. Celia Green distinguished between tribal and territorial morality. Tribal morality is prescriptive. It imposes the norms of a collective onto the individual. These norms are often flexible and depend on culture. Territorial morality is predominantly negative and proscriptive. It defines a person's territory, such as property or dependents. It forbids interference with that territory. However, it is permissive regarding other behaviors. This type of morality aims for universal and absolute rules.
Social groups often create boundaries between "in-groups" and "out-groups." An in-group includes the individual and those they believe are part of their group. An out-group consists of people not entitled to the same moral rules. Some biologists believe this discrimination helps group survival. Computational models of evolution have supported this idea. In simulations, this can cause cooperation within the in-group. It can also cause irrational hostility toward the out-group. This preference can also occur at the individual level. For example, a mother may favor her own children to ensure their survival. This helps pass on her genes to the next generation.
Researchers have looked for patterns across many different cultures. Anthropologists at Oxford analyzed ethnographic accounts from 60 different societies. They studied over 600,000 words from more than 600 sources. They discovered seven universal moral rules. These include helping your family and helping your group. They also include returning favors and being brave. Other rules include deferring to superiors, dividing resources fairly, and respecting property.
