The Science of Social Influence
Introduction: There’s one Indian saying, vaguely translated to: “The company we keep influences our lives.”
This captures one core point of social influence: our thoughts, feelings, and behaviour are shaped not only by our own choices, but also by the people and social environments around us. We might think of our choices as entirely formed on our own, yet they could be shaped by the people around us.
The way we speak, dress, or spend money can change because of peers, family, media exposure, and society. Social psychology studies this connection between the individual and the social world. It shows that people are not truly independent decision-makers; their thoughts, feelings, and actions develop and construct within social situations.

Anthony R. Pratkanis’s View of Social Influence
According to Anthony R. Pratkanis in the book The Science of Social Influence, social influence includes conformity, persuasion, compliance, and changes produced by the social situation. It can happen through direct pressure, but it can also happen without anyone intentionally trying to influence us. One may change an opinion after hearing peers discuss an issue, mimic online trend, or follow a rule simply because it feels ‘normal’.
Peers Influence
Peers are one of the most important daily sources of influence. People often want to belong, so they may adjust their behaviour to match any group. Conformity can come from the desire for approval, or protection from being rejected or left out.
However, conformity is not always bad. Following common or shared rules, such as following traffic rules, helps social life remain orderly. The same pressure, though, can end up produce harmful behaviour as well when people follow a group without ever questioning it, for example ‘human sacrifices’ to appease the gods or slavery.
Family Influence
Family is another major institution of influence, especially for socialization. Children learn language, manners, beliefs, norms, and ideas about ‘acceptable behaviour’ through interaction with their family. The social environment in which one grows up contributes to how one understands themselves. Family therefore does not simply tell a person what to do; it also helps build the standards through which future choices emerge.
Influence of Social Media Platforms
Furthermore, social media platforms can frame how people perceive behaviour through likes, comments, shares, and trends. A person may get fixated on one particular opinion, or lifestyle, as normal because algorithm shows it repeatedly or because many other netizens might support it. This connects with informational influence: when a situation is uncertain, people may look to others for clues regarding what is correct. Persuasion also works through messages, especially when the source appears credible or the message feels personally relatable.
Social Influence & Society
Society also constructs a framework. Cultural norms influence what people consider polite, successful, attractive, appropriate, or acceptable. Social influence can spread through social networks rather than from one person alone. Pratkanis describes influence as operating through communication networks, social institutions, and patterns of interaction. A belief can become common or normal because people repeatedly influence one another and keep following the certain norm; while a minority can also challenge an established norm.
Conclusion
The behaviour is shaped through continuous interaction with others in the social system. Peers can affect choices, family can shape habits and values, media can spread opinions and trends, and society provides broader norms for behaviour. Yet influence does not remove individual agency. People can question peer pressure, examine information available online, and decide whether a social expectation deserves acceptance or is outdated and irrelevant. Understanding social influence is therefore not only about explaining why people conform. It is also about recognizing the social forces around us so that our decisions become more conscious, informed and relevant.
