Study
Human behavior is studied by the
social sciences, which include
psychology,
sociology,
ethology, and their various branches and schools of thought. The study of human behavior includes how the human mind
evolved and how the
nervous system controls behavior. The
nature versus nurture
Nature versus nurture is a long-standing debate in biology and society about the balance between two competing factors which determine fate: genetics (nature) and environment (nurture). The alliterative expression "nature and nurture" in English h ...

Twin studies are a common method by which human behavior is studied.
Twins with identical
genomes can be compared to isolate genetic and environmental factors in behavior. Lifestyle, susceptibility to disease, and unhealthy behaviors have been identified to have both genetic and environmental indicators through twin studies.
Social behavior
Human social behavior is the behavior that considers other humans, including communication and cooperation. It is highly complex and structured, based on advanced
theory of mind that allows humans to attribute thoughts and actions to one another. Through social behavior, humans have developed
society and
culture distinct from other animals. Human social behavior is governed by a combination of biological factors that affect all humans and cultural factors that change depending on upbringing and societal norms. Human communication is based heavily on
language, typically through
speech
Speech is a human vocal communication using language. Each language uses Phonetics, phonetic combinations of vowel and consonant sounds that form the sound of its words (that is, all English words sound different from all French words, even if ...
or
writing.
Nonverbal communication and
paralanguage can modify the meaning of communications by demonstrating ideas and intent through physical and vocal behaviors.
Social norms
Human behavior in a society is governed by
social norms. Social norms are unwritten expectations that members of society have for one another. These norms are ingrained in the particular culture that they emerge from, and humans often follow them unconsciously or without deliberation. These norms affect every aspect of life in human society, including
decorum,
social responsibility,
property rights,
contractual agreement
A contract is a legally enforceable agreement between two or more parties that creates, defines, and governs mutual rights and obligations between them. A contract typically involves the transfer of goods, services, money, or a promise to tran ...

meaning

. Many norms facilitate coordination between members of society and prove mutually beneficial, such as norms regarding communication and agreements. Norms are enforced by
social pressure, and individuals that violate social norms risk
social exclusion.
Systems of
ethics are used to guide human behavior to determine what is moral. Humans are distinct from other animals in the use of ethical systems to determine behavior. Ethical behavior is human behavior that takes into consideration how actions will affect others and whether behaviors will be optimal for others. What constitutes ethical behavior is determined by the individual
value judgments of the person and the collective social norms regarding right and wrong. Value judgments are intrinsic to people of all cultures, though the specific systems used to evaluate them may vary. These systems may be derived from
divine law,
natural law,
civil authority,
reason, or a combination of these and other principles.
Altruism
Altruism is the principle and moral practice of concern for the welfare and/or happiness of other human beings or animals, resulting in a quality of life both material and spiritual. It is a traditional virtue in many cultures and a core as ...
is an associated behavior in which humans consider the welfare of others equally or preferentially to their own. While other animals engage in biological altruism, ethical altruism is unique to humans.
Deviance is behavior that violates social norms. As social norms vary between individuals and cultures, the nature and severity of a deviant act is subjective. What is considered deviant by a society may also change over time as new social norms are developed. Deviance is punished by other individuals through
social stigma,
censure, or
violence. Many deviant actions are recognized as
crimes and punished through a system of
criminal justice. Deviant actions may be punished to prevent harm to others, to maintain a particular worldview and way of life, or to enforce principles of morality and
decency. Cultures also attribute positive value to certain physical traits, causing individuals that do not have these traits to be seen as deviant.
Interpersonal relationships
Interpersonal relationships can be evaluated by the specific choices and emotions between two individuals, or they can be evaluated by the broader societal context of how such a relationship is expected to function. Relationships are developed through communication, which creates intimacy, expresses emotions, and develops identity. An individual's interpersonal relationships form a
social group in which individuals all communicate and socialize with one another, and these social groups are connected by additional relationships. Human social behavior is affected not only by individual relationships, but also by how behaviors in one relationship may affect others. Individuals that actively seek out social interactions are
extraverts, and those that do not are introverts.

interpersonal attraction toward another. Its nature varies by culture, but it is often contingent on gender, occurring in conjunction with

or extended relatives.
Politics and conflict

When humans make decisions as a group, they engage in politics. Humans have evolved to engage in behaviors of
self-interest, but this also includes behaviors that facilitate cooperation rather than conflict in collective settings. Individuals will often form
in-group and out-group
In sociology and social psychology, an in-group is a social group to which a person psychologically identifies as being a member. By contrast, an out-group is a social group with which an individual does not identify. People may for example ide ...
perceptions, through which individuals cooperate with the in-group and compete with the out-group. This causes behaviors such as unconsciously conforming, passively obeying authority, taking pleasure in the misfortune of opponents, initiating hostility toward out-group members, artificially creating out-groups when none exist, and punishing those that do not comply with the standards of the in-group. These behaviors lead to the creation of
political system
In political science, a political system means the type of political organization that can be recognized, observed or otherwise declared by a state.

s that enforce in-group standards and norms.
When humans oppose one another, it creates conflict. It may occur when the involved parties have a

anger toward one another. Conflicts purely of disagreement are often resolved through communication or
negotiation, but incorporation of emotional or obstructive aspects can escalate conflict.
Interpersonal conflict is that between specific individuals or groups of individuals.
Social conflict is that between different social groups or demographics. This form of conflict often takes place when groups in society are marginalized, do not have the resources they desire, wish to instigate social change, or wish to resist social change. Significant social conflict can cause

Cognitive behavior

Human cognition is distinct from that of other animals. This is derived from biological traits of human cognition, but also from shared
knowledge and development passed down culturally. Humans are able to learn from one another due to advanced theory of mind that allows knowledge to be obtained through
education. The use of language allows humans to directly pass knowledge to one another.

human brain has
neuroplasticity, allowing it to modify its features in response to new experiences. This facilitates

Humans engage in
reason to make
inferences with a limited amount of information. Most human reasoning is done automatically without conscious effort on the part of the individual. Reasoning is carried out by making generalizations from past experiences and applying them to new circumstances. Learned knowledge is acquired to make more accurate inferences about the subject.

Emotion is a cognitive experience innate to humans. Basic emotions such as
joy,
distress,
anger,
fear,
surprise, and
disgust are common to all cultures, though social norms regarding the expression of emotion may vary. Other emotions come from higher cognition, such as
love,
guilt,
shame,
embarrassment,
pride,
envy, and
jealousy. These emotions develop over time rather than instantly and are more strongly influenced by cultural factors. Emotions are influenced by
sensory information, such as
color and
music, and
moods of
happiness and
sadness. Humans typically maintain a standard level of happiness or sadness determined by health and social relationships, though positive and negative events have short-term influences on mood. Humans often seek to improve the moods of one another through
consolation,
entertainment, and
venting. Humans can also self-regulate mood through

and
meditation.
Creativity is the use of previous ideas or resources to produce something original. It allows for
innovation, adaptation to change, learning new information, and novel problem solving. Expression of creativity also supports
quality of life. Creativity includes personal creativity, in which a person presents new ideas
authentically, but it can also be expanded to social creativity, in which a community or society produces and recognizes ideas collectively. Creativity is applied in typical human life to solve problems as they occur. It also leads humans to carry out
art and
science. Individuals engaging in advanced creative work typically have specialized knowledge in that field, and humans draw on this knowledge to develop novel ideas. In art, creativity is used to develop new artistic works, such as
visual art or
music. In science, those with knowledge in a particular scientific field can use
trial and error to develop theories that more accurately explain phenomena.

rational choice models of human behavior, though it does provide community-related benefits. Anthropologists offer competing theories as to why humans adopted religious behavior.

religious organizations or family units allow the sharing and coordination of religious behavior. These social connections reinforce the cognitive behaviors associated with religion, encouraging

settings. In these societies, production is increased, ending the need for constant work and allowing some individuals to specialize and work in areas outside of food-production. This also created non-laborious work, as increasing occupational complexity required some individuals to specialize in technical knowledge and administration. Laborious work in these societies has variously been carried out by slaves, serfs, peasants, and guild craftsmen. The nature of work changed significantly during the
Industrial Revolution in which the
factory system was developed for use by industrializing nations. In addition to further increasing general quality of life, this development changed the dynamic of work. Under the factory system, workers increasingly collaborate with others, employers serve as authority figures during work hours, and forced labor is largely eradicated. Further changes occur in
post-industrial societies where technological advance makes industries obsolete, replacing them with
mass production
Mass production, also known as flow production or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch ...
and
service industries.
Humans approach work differently based on both physical and personal attributes, and some work with more effectiveness and commitment than others. Some find work to contribute to personal fulfillment, while others work only out of necessity. Work can also serve as an identity, with individuals identifying themselves based on their occupation.
Work motivation is complex, both contributing to and subtracting from various human needs. The primary motivation for work is for material gain, which takes the form of
money in modern societies. It may also serve to create self-esteem and personal worth, provide activity, gain respect, and express creativity. Modern work is typically categorized as laborious or
blue-collar work and non-laborious or
white-collar work.
Leisure

Leisure is activity or lack of activity that takes place outside of work. It provides relaxation,
entertainment, and improved quality of life for individuals. Casual leisure behaviors provide short-term gratification, but they do not provide long-term gratification or personal identity. These include
play, relaxation, casual social interaction,
volunteering, passive entertainment, active entertainment, and sensory stimulation. Passive entertainment is typically derived from
mass media, which may include written works or

Ecological behavior

Like all living things, humans live in
ecosystems and interact with other organisms. Human behavior is affected by the environment in which a human lives, and environments are affected by human habitation. Humans have also developed man-made ecosystems such as
urban areas and
agricultural land. Geography and
landscape ecology determine how humans are distributed within an ecosystem, both naturally and through planned
urban morphology.
Humans exercise control over the animals that live within their environment.

Factors
Human behavior is influenced by biological and cultural elements. The
structure and agency debate considers whether human behavior is predominantly led by individual human impulses or by external structural forces.
Behavioral genetics considers how human behavior is affected by inherited traits. Though genes do not guarantee certain behaviors, certain traits can be inherited that make individuals more likely to engage in certain behaviors or express certain personalities. An individual's environment can also affect behavior, often in conjunction with genetic factors. An individual's
personality and
attitudes affect how behaviors are expressed, formed in conjunction by genetic and environmental factors.

temperament, and
genetics may be more consistent, other behaviors change as one moves between life stages—i.e., from birth through
