Need in the context of "Want"

Commerce is the organized system of activities, functions, procedures and institutions that directly or indirectly contribute to the smooth, unhindered exchange of goods, services, and other things of value—predominantly through transactional processes—at the right time, place, quantity, quality and price through various channels among the original producers and the final consumers within local, regional, national or international economies. The diversity in the distribution of natural resources, differences of human needs and wants, and division of labour along with comparative advantage are the principal factors that give rise to commercial exchanges.

Commerce consists of trade and aids to trade (i.e. auxiliary commercial services) taking place along the entire supply chain. Trade is the exchange of goods (including raw materials, intermediate and finished goods) and services between buyers and sellers in return for an agreed-upon price at traditional (or online) marketplaces. It is categorized into domestic trade, including retail and wholesale as well as local, regional, inter-regional and international/foreign trade (encompassing import, export and entrepôt/re-export trades). The exchange of currencies (in foreign exchange markets), commodities (in commodity markets/exchanges) and securities and derivatives (in stock exchanges and financial markets) in specialized exchange markets, typically operating under the domain of finance and investment, also falls under the umbrella of trade. On the other hand, auxiliary commercial activities (aids to trade) which can facilitate trade include commercial intermediaries, banking, credit financing and related services, transportation, packaging, warehousing, communication, advertising and insurance. Their purpose is to remove hindrances related to direct personal contact, payments, savings, funding, separation of place and time, product protection and preservation, knowledge and risk.

Social influence comprises the ways in which individuals adjust their behavior to meet the demands of a social environment. It takes many forms and can be seen in conformity, socialization, peer pressure, obedience, leadership, persuasion, sales, and marketing. Typically social influence results from a specific action, command, or request, but people also alter their attitudes and behaviors in response to what they perceive others might do or think. In 1958, Harvard psychologist Herbert Kelman identified three broad varieties of social influence.

1. Compliance is when people appear to agree with others but actually keep their dissenting opinions private.
2. Identification is when people are influenced by someone who is liked and respected, such as a famous celebrity.
3. Internalization is when people accept a belief or behavior and agree both publicly and privately.

Morton Deutsch and Harold Gerard described two psychological needs that lead humans to conform to the expectations of others. These include our need to be right (informational social influence) and our need to be liked (normative social influence). Informational influence (or social proof) is an influence to accept information from another as evidence about reality. Informational influence comes into play when people are uncertain, either from stimuli being intrinsically ambiguous or because of social disagreement. Normative influence is an influence to conform to the positive expectations of others. In terms of Kelman's typology, normative influence leads to public compliance and identification, whereas informational influence leads to private acceptance and internalization.

In social science and economics, public interest is "the welfare or well-being of the general public" and society.

While it has earlier philosophical roots and is considered to be at the core of democratic theories of government, often paired with two other concepts, convenience and necessity, it first became explicitly integrated into governance instruments in the early part of the 20th century.

Belongingness is the human emotional need to be an accepted member of a group. Whether it is family, friends, co-workers, a religion, or something else, some people tend to have an 'inherent' desire to belong and be an important part of something greater than themselves. This implies a relationship that is greater than simple acquaintance or familiarity.

Belonging is a strong feeling that exists in human nature. To belong or not to belong is a subjective experience that can be influenced by a number of factors within people and their surrounding environment. A person's sense of belonging can greatly impact the physical, psychological, and spiritual emotions within themselves.

Social connection is the experience of feeling close and connected to others. It involves feeling loved, cared for, and valued, and forms the basis of interpersonal relationships.

Increasingly, social connection is understood as a core human need, and the desire to connect as a fundamental drive. It is crucial to development; without it, social animals experience distress and face severe developmental consequences. In humans, one of the most social species, social connection is essential to nearly every aspect of health and well-being. Lack of connection, or loneliness, has been linked to inflammation, accelerated aging and cardiovascular health risk, suicide, and all-cause mortality.

In Freudian psychoanalysis, the pleasure principle (German: Lustprinzip) is the instinctive seeking of pleasure and avoiding of pain to satisfy biological and psychological needs. Specifically, the pleasure principle is the animating force behind the id.
