Real-World Applications of Social Influence
The research covered in this topic has important implications for understanding and addressing real-world issues. Social influence affects behaviour in everyday life, from advertising to the justice system, from workplace dynamics to online behaviour.
Applications to the Criminal Justice System
Eyewitness Testimony and Conformity
Research on conformity has important implications for eyewitness testimony:
- Post-event discussion between witnesses can lead to memory conformity (Gabbert et al., 2003) — witnesses may incorporate details from others' accounts into their own memory
- Police should keep witnesses separate to prevent conformity effects on their testimony
- Line-up procedures should be designed to minimise social influence — for example, witnesses should be told that the suspect may or may not be in the line-up
Jury Decision-Making
Conformity research is relevant to jury deliberation:
- Jurors may conform to the majority view due to normative social influence (wanting to fit in with the group)
- They may also be influenced by informational social influence (believing others have better knowledge)
- Asch's findings suggest that unanimous majorities are particularly persuasive, but a single dissenter can reduce conformity
- This has implications for the size and composition of juries
Applications to Organisations and the Workplace
Obedience in the Workplace
Milgram's research on obedience has implications for understanding:
- Corporate misconduct — employees may follow unethical orders from superiors because of the agentic state
- Whistleblowing — employees who resist obedience and report wrongdoing are acting in the autonomous state
- Military obedience — understanding the factors that promote obedience helps explain military atrocities and informs training to prevent them
Social Loafing
Understanding social loafing helps organisations:
- Design teams where individual contributions are identifiable
- Set clear goals and hold individuals accountable
- Use smaller teams for tasks requiring maximum effort
Applications to Health and Behaviour Change
Conformity and Health Behaviours
Social norms influence health behaviours:
- People are more likely to exercise, eat healthily, or quit smoking if their social group does these things
- Normative social influence can be harnessed in public health campaigns by communicating that "most people" engage in healthy behaviours
- Example: Hotel towel reuse campaigns that say "75% of guests in this room chose to reuse their towels" increase reuse rates (Goldstein et al., 2008)
Peer Pressure
Understanding conformity helps address:
- Teenage substance use — adolescents may use drugs or alcohol due to normative social influence from peers
- Interventions can teach young people about the psychology of conformity and strategies for resisting peer pressure

Applications to Online Behaviour
Deindividuation Online
The internet creates conditions that promote deindividuation:
- Anonymity — online users often use pseudonyms or anonymous accounts
- Reduced accountability — people feel they will not be identified or punished
- Physical distance — the victim is not visible
These factors explain why cyberbullying, trolling, and online aggression are common. Research on deindividuation suggests that reducing anonymity (e.g. requiring real names on social media) could reduce these behaviours.
Online Conformity
Social media also promotes conformity:
- Likes, shares, and comments create social pressure to conform to popular opinions
- Algorithmic echo chambers reinforce existing beliefs, creating the impression of unanimous agreement
- People may post content that conforms to their group's norms rather than expressing their genuine views
Applications to Education
Growth Mindset and Social Influence
Dweck's research (covered in the Development topic) connects with social influence:
- Classroom norms influence whether students adopt a growth or fixed mindset
- If the class culture values effort and improvement, students are more likely to develop a growth mindset (conformity to positive norms)
- Teachers are authority figures — their feedback and behaviour significantly influence students' beliefs and behaviours
Reducing Prejudice
Understanding obedience and conformity can help reduce prejudice:
- Schools can use authority (teachers) to model and enforce inclusive behaviour
- Group norms that value diversity and inclusion reduce prejudice through conformity
- Education about the psychology of obedience and conformity can make students more aware of social influence and more resistant to harmful group pressure
Ethical Implications of Social Influence Research
The research on social influence raises important ethical questions:
| Issue | Question |
|---|
| Manipulation | Is it ethical to use knowledge of social influence to change people's behaviour (e.g. in advertising or political campaigns)? |
| Autonomy | Should people be made aware of how social influence affects them so they can make more autonomous choices? |
| Protection | How can vulnerable individuals (children, elderly, those with cognitive impairments) be protected from harmful social influence? |
| Responsibility | If someone harms another while obeying orders, who is morally responsible — the person who obeyed or the authority who gave the order? |
Exam Tip: When discussing real-world applications, always link back to specific research and psychological concepts. For example, when discussing cyberbullying, reference deindividuation and Zimbardo's theory. When discussing peer pressure, reference Asch and normative social influence.
Key Points
- Social influence research applies to the criminal justice system (eyewitness conformity, jury decisions).
- Milgram's findings are relevant to understanding obedience in the workplace and military.
- Conformity influences health behaviours and can be used in public health campaigns.
- Deindividuation explains online aggression and cyberbullying.
- Understanding social influence helps design interventions for education, prejudice reduction, and health.
Worked study: Piliavin, Rodin & Piliavin (1969) — the "subway Samaritan"
Piliavin's subway study is a powerful real-world application of social influence research because it was conducted in a natural setting and directly informs how we understand helping behaviour in public life.
Aim: To investigate factors affecting bystander helping behaviour in a realistic setting, specifically whether the type of victim (ill vs drunk), race of victim, and size of the group of witnesses affect helping.
