Scoring your answers…

Social influence is the process by which an individual’s attitudes, beliefs or behaviour are modified by the presence or action of others. AQA examines four areas: conformity (yielding to group pressure), obedience (following an authority’s order), resistance to social influence, and minority influence (minorities changing majority views).

Conformity (Majority Influence)

Conformity is defined as a type of social influence. It is yielding to group pressure: a change in a person’s behaviour or opinion due to real or imagined pressure from a person or group.

Real pressure involves consequences for conforming, while imagined pressure involves none for not conforming. Conformity is also known as majority influence.

Students will be expected to know:

  • Types of conformity: internalisation (accepting the group’s view in public and in private) and compliance (agreeing in public while privately disagreeing).
  • Explanations for conformity: informational social influence (conforming to be right) and normative social influence (conforming to be liked).
  • Variables affecting conformity including group size, unanimity and task difficulty as investigated by Asch.

Types of Conformity

According to Kelman (1958), there are three types of conformity: internalisation, identification, and compliance.

These are also sometimes seen as levels of conformity. Note: you no longer need to learn about identification for the 2027 exam.

An older specification also examined conformity to social roles (Zimbardo’s Stanford Prison Experiment) as part of this topic. That content has been removed too, so do not bring Zimbardo’s study into a conformity answer on the current specification.

Compliance AO1

This refers to instances where a person may agree in public with a group, but privately disagrees with the group’s viewpoint or behaviour.

The change is temporary and superficial. It is driven by the desire to gain approval or avoid disapproval, often through normative pressure.

For example, a person may laugh at a joke because their friends find it funny, even though deep down they don’t find it funny themselves.

Drinking alcohol with friends despite not wanting to, then not drinking outside those social situations, is another example.

Compliance is the weakest form of conformity. It lasts only as long as group pressure is present.

For a study on compliance refer to Asch’s Line Study.

Internalisation AO1

Publicly changing behaviour to fit in with the group while also agreeing with them privately.

An internal (private) and external (public) change of behaviour.

This is the deepest level of conformity, where the beliefs of the group become part of the individual’s own belief system.

This type of conformity usually lasts without the majority present. It links to Informational Social Influence.

An example of internalisation is someone who lived with a vegetarian at university and decided to also become one, because they agreed with their friend’s viewpoint. Converting to a different religion after living among people of that faith would be another good example.

For a study on internalisation refer to Jenness (see below).

Normative Influence (AO1/AO3)

Normative social influence is where a person conforms because they want to be liked and be part of a group.

It is driven by a person’s need to be accepted or have approval from a group.

Normative social influence is usually associated with compliance, where a person changes their public behaviour but not their private beliefs.

This form of influence is shallow. People often use it to avoid the embarrassing situation of disagreeing with the majority, or through fear of rejection or being seen as an outcast.

For example, a person may feel pressurised to smoke because their friends do. Normative social influence tends to lead to compliance: the person smokes just for show, but deep down wishes not to smoke. Any change of behaviour is therefore temporary.

For a study on normative influence refer to Asch.

Not everyone is equally affected by normative pressure. People with a high need for affiliation (nAffiliators) are more likely to conform to be liked, whereas others less concerned with social approval may resist NSI.

Informational Influence (AO1/AO3)

Informational social influence is where a person conforms because they have a desire to be right.

They look to others who they believe have more information.

This usually happens when a person is uncertain or unsure of a situation or lacks knowledge.

It usually leads to internalisation. That is a permanent change in view or behaviour, not just a public one.

It occurs in ambiguous, difficult, or novel situations where we lack the knowledge or expertise to make our own decisions.

For example, a person may follow a crowd in an emergency, assuming others know the way.

Imagine going to a posh restaurant for the first time. Confronted with several forks and unsure which to use, a person might look to someone nearby to see which one they pick up first.

For a study on informational influence refer to Jenness (see below).

Jenness’ Bean Jar Experiment AO1

Jenness carried out a study into conformity. In his experiment, participants were asked to estimate how many beans they thought were in a jar.

Each participant had to make an individual estimate, and then do the same as a group.

He found that when the task was carried out in a social group, participants reported estimates of roughly the same value.

This is despite differing individual estimates just before.

The study successfully showed majority influence: individuals’ behaviour and beliefs can be influenced by a group.

This is likely an example of informational social influence, since participants would be uncertain about the actual number of beans in the jar.

Variables Affecting Conformity

Asch’s Line Study AO1

asch line study
  • Aim: Asch wanted to investigate whether people would conform to the majority in situations where an answer was obvious.
  • Procedure: Asch’s study had 5-7 participants per group. Each group saw a standard line and three comparison lines, and said aloud which comparison line matched the standard in length.
  • Confederates: One participant in each group was real and the rest were confederates. The confederates were told to give the incorrect answer on 12 of 18 trials.
  • Results: Real participants conformed on 32% of the critical trials where confederates gave the wrong answers. Additionally, 75% of the sample conformed to the majority on at least one trial.

Factors Affecting Conformity AO3

In further trials, Asch (1952, 1956) changed the procedure (i.e., independent variables) to investigate which situational factors influenced the level of conformity (dependent variable).  His results and conclusions are given below:

1. Group Size

An individual is more likely to conform in a larger group.

Group size matters. Asch altered the number of confederates in his study to see how this affected conformity. The bigger the majority group, the more people conformed, but only up to a point.

With one confederate, conformity was 3%. With two, it rose to 13%. With three or more, it reached 32%.

Conformity levels off at about three confederates. Adding more has little further effect. Asch treated a majority of roughly three to five as the optimal size.

group size

Brown and Byrne (1997) suggest that people might suspect collusion if the majority rises beyond three or four.

According to Hogg & Vaughan (1995), the most robust finding is that conformity reaches its full extent with 3-5 person majority, with additional members having little effect.

2. Group Unanimity

A person is more likely to conform when all members of the group agree and give the same answer.

When one other person in the group gave a different answer from the others, and the group answer was not unanimous, conformity dropped.

Asch (1951) found that even the presence of just one confederate that goes against the majority choice can reduce conformity as much as 80%.

3. Difficulty of Task

An individual is more likely to conform when the task is difficult.

When the (comparison) lines (e.g., A, B, C) were made more similar in length it was harder to judge the correct answer and conformity increased.

When we are uncertain, it seems we look to others for confirmation. The more difficult the task, the greater the conformity.

This suggests that informational social influence is a major mechanism for conformity when the situation is ambiguous.

4. Answer in Private

When participants were allowed to answer in private (so the rest of the group does not know their response) conformity decreases.

This decreases conformity because there are fewer group pressures and normative influence is not as powerful, as there is no fear of rejection.

Contemporary Research

The classic percentage is a product of period and place. Bond and Smith’s (1996) meta-analysis of 133 Asch-type experiments from 17 countries found conformity had declined in US studies since the 1950s. It was higher in more collectivist countries. Has the effect vanished? A recent replication suggests not.

  • Aim: Franzen and Mader (2023) replicated Asch’s line experiment to test whether payment for correct answers changes the error rate. They also tested political statements and personality links.
  • Method: Groups of five confederates and one naive participant (N = 210) judged lines. Some line decisions were financially incentivised in a randomised trial, and participants also faced political statements.
  • Results: The standard line task produced an error rate of 33%, in line with Asch. The incentive lowered it to 25%, and political statements produced a conformity rate of 38%.
  • Conclusion: Conformity to a unanimous group persists. Incentives reduce it but do not remove it, and it reaches opinion statements as well as perceptual judgements.

The incentive manipulation was randomised, which is a strength. However, an error on the line task cannot separate private acceptance from public compliance. The result therefore says little about the informational versus normative distinction on the specification.

Obedience

Obedience is a type of social influence where a person follows an order from another person who is usually an authority figure.

Students will be expected to know:

  • Explanations for obedience: agentic state (acting for an authority and feeling no personal responsibility) and legitimacy of authority (the perceived right to give orders).
  • Situational variables affecting obedience including proximity and location, as investigated by Milgram, and uniform.
  • Dispositional explanation for obedience: the Authoritarian Personality (a rigid, status-conscious personality type linked to obedience).

Explanations for Obedience

Milgram’s Shock Study AO1

Milgram wanted to know why Germans were willing to kill Jews during the Holocaust.

He thought it might be because Germans were simply evil.

But he thought Americans were different, and would not have followed such orders. To test this ‘Germans are different’ hypothesis, he carried out the study outlined below.

milgram obedience

  • Aim: Milgram wanted to see whether people would obey a legitimate authority figure when told to harm another person.
  • Procedure: In a lab experiment, the real participant was always the teacher and a confederate, Mr. Wallace, was the learner. They sat in separate rooms.
  • Shocks: The experimenter, Mr Williams, wore a grey lab coat and asked the teacher to shock the learner for each wrong answer. The shocks were actually harmless and rose from 15 to 450 volts.
  • Prods: When the participant refused, the experimenter gave a series of orders, or prods. If one was not obeyed, he read out the next:
    • Prod 1: please continue.
    • Prod 2: the experiment requires you to continue.
    • Prod 3: It is absolutely essential that you continue.
    • Prod 4: you have no other choice but to continue.
  • Results: All participants went to 300 volts, and 65% went all the way to 450 volts.
  • Variations: Milgram ran 18 variations, each altering the situation (the IV) to see how it affected obedience (the DV). For example, telephone instructions from another room cut obedience to 20.5%.

milgram scale

The Agentic State

This is when a person believes that someone else will take responsibility for their actions.

Agency theory suggests people obey more readily in the agentic state. They do not believe they will suffer the consequences of their actions.

They believe they are acting on behalf of an agent.

 The shift from an autonomous state (where a person takes responsibility for their own actions) to the agentic state is called an Agentic Shift.

Agency theory is supported by Milgram’s evidence. When participants were reminded they had responsibility, few obeyed; but many who had been refusing continued if the experimenter said he would take responsibility.

Another example of the agentic state involved a variation of Milgram’s study whereby participants could instruct an assistant (confederate) to press the switches.

In this condition 92.5% shocked to the maximum 450 volts. This shows when there is less personal responsibility obedience increases.

Being in the agentic state makes a person ‘unthinkingly’ carry out orders and involves diffusion of responsibility.

Limitations AO3

  • Nazi behaviour: Mandel described the German Police Reserve shooting civilians in a Polish town without a direct order, despite being told they could be reassigned. They were not powerless to obey, which challenges the agentic state.
  • Plain cruelty: Zimbardo’s guards inflicted rapidly escalating cruelty with no authority figure telling them to, suggesting obedience may reflect aspects of human nature.

The Stanford prison study is itself contested, however. An archival investigation found demand characteristics and guards who received precise instructions (Le Texier, 2019). The BBC prison study found that guards who failed to identify with their role were overcome by prisoners (Reicher & Haslam, 2006).

Situational Variables Affecting Obedience as Investigated by Milgram

The Milgram experiment was carried out many times whereby Milgram varied the basic procedure (changed the IV).

By doing this Milgram could identify which situational factors affected obedience (the DV).

Obedience was measured by how many participants shocked to the maximum 450 volts (65% in the original study).

1. Authority Figure Wearing a Uniform

Milgram’s experimenter (Mr. Williams) wore a grey laboratory coat (a symbol of scientific expertise) which gave him a high status.

However, when the experimenter dressed in everyday clothes, obedience was very low. 

Uniform acts as a visible sign of authority, increasing legitimacy and status.

2. Status of Location

Milgram’s obedience experiment was conducted at Yale, a prestigious university in America.

The high status of the university gave the study credibility and respect in the eyes of the participants, thus making them more likely to obey.

When Milgram moved his experiment to a set of run down offices rather than the impressive Yale University obedience dropped to 47.5%. This suggests that status of location effects obedience.

3. Proximity of Authority Figure (and Learner)

This refers to the physical closeness between the teacher, the learner, and the experimenter.

People are more likely to obey an authority figure nearby.

In Milgram’s study the experimenter was in the same room as the participant (i.e. teacher).

Distance makes it easier to resist an order.

When the experimenter instructed the teacher by telephone from another room, obedience fell to 20.5%.

Decreased proximity to the authority figure meant participants returned to a more autonomous state.

Many participants cheated, missing out shocks or giving less voltage than ordered to by the experimenter.

Dispositional Explanation: Authoritarian Personality

Adorno felt that personality (dispositional) factors, rather than situational (environmental) ones, could explain obedience. This is the authoritarian personality.

It is a person who favours an authoritarian social system and admires obedience to authority figures. One characteristic of the authoritarian personality is that the individual is hostile to those of inferior status, but obedient toward people with high status.

They show a strict adherence to conventional norms, an intolerance of ambiguity, and a black-and-white worldview with no grey areas. Everyone should know their place.

There is no challenge to those above, and no mercy to those below. Adorno measured this using the F-scale, testing around 2,000 middle-class white Americans’ unconscious attitudes towards other racial groups.

Those with higher F-scale scores showed the traits of an authoritarian personality. They were more prejudiced. They also viewed society as needing strong leaders to eradicate evil, and were inflexible in their outlook.

Limitations AO3

  • Correlation, not causation: Adorno found many significant correlations (e.g. authoritarianism correlated with prejudice against minority groups). But one variable cannot be said to cause another. Adorno cannot claim that a harsh parenting style caused an authoritarian personality, so other explanations like legitimacy of authority must be considered.
  • Obedience without the personality: Millions of individuals in Germany displayed obedient behaviour but did not share the same personality. It is unlikely that most of Germany’s population possessed an authoritarian personality. Social identity theory may be more realistic. People identify with groups they belong to and discriminate against others.
  • Better explanations: Prejudice and submissiveness could just as easily be caused by a poor standard of education as a child. The theory lacks internal validity. It assumes obedience is dispositional when it may be situational.
  • Biased sample: Adorno used only 2000 middle class white Americans. They are more likely to have an authoritarian personality because of their demographics and the time of the study. The research lacks population validity and historical validity, so conclusions cannot be generalised to people outside the sample.

Resistance to Social Influence

Resisting social influence means not yielding to pressures to conform or obey. Two key factors help people resist: the presence of social support, and an individual’s locus of control. Locus of control is how much control a person feels they have over events in their life.

Students will be expected to know:

  • Explanations of resistance to social influence, including social support and locus of control.

Other possible explanations for resistance include reactance (the “boomerang effect”), status, morality, and being in an autonomous state.

  • Previous experience and a high level of moral reasoning
  • Situational factors: lack of uniform, increased distance, reduced group size, or lack of task ambiguity
  • Prior commitment

Social Support

The presence of people helps others resist pressure to conform or obey.

Having an ally or seeing someone else resist can strengthen an individual’s ability to withstand group or authority pressure

1. Resisting Conformity:

Seeing others non-conform gives confidence to do so. Having an ally breaks the unanimity of the group.

In Asch’s conformity experiments, a single confederate who disagreed with the majority cut a participant’s conformity to about a quarter of its previous level. This held even with a different wrong answer.

Just one dissenter broke the unanimity and provided a model of independent behaviour, making it easier for the participant to follow their own conscience.

The ally’s dissent confirms the participant’s own perceptions: “I’m not the only one who sees it differently.” It also reduces normative pressure. The majority is no longer unanimous in disapproval.

Essentially, the presence of a non-conforming person frees others to not conform. This effect isn’t long-lasting if the ally starts conforming again, but at least temporarily, it boosts confidence.

2. Resisting Obedience:

Disobedient models facilitate disobedience.

Seeing others disobey shows that defying the experimenter is possible. It can also sharpen a participant’s own sense of personal responsibility. This is powerful.

In Milgram’s obedience variations, participants worked in a team of three teachers, two of them confederates who refused to continue at certain points. The real participant’s obedience plummeted.

Only 10% continued to 450V once they saw their peers disobey the experimenter.

The disobedient confederates modelled rebellion. They showed the participant that one can stand up to authority, making it far easier to defy the experimenter’s orders.

Gamson et al. (1982) ran a related study. Participants in groups discussed a morally questionable situation, helping an oil company smear a manager’s reputation.

They found that 88% of groups rebelled against the orders, a much higher rate than Milgram found in individuals. Groups can reinforce each other’s resistance. This is the key difference from Milgram’s individually tested participants.

These findings show that social support undermines the legitimacy of authority or majority pressure, giving individuals courage to resist.

Why does it work? Social support works through two pathways: normative social influence (NSI) and informational social influence (ISI).

An ally reduces the fear of isolation, since you’re not the only deviant. That is NSI. They can also provide an alternative viewpoint that might be correct. That is ISI.

For example, in Asch’s study, a dissenter giving the correct answer broke unanimity and validated the participant’s own judgment. This reduces conformity through both normative and informational influence.

In essence, there is strength in numbers. Even a small break in consensus can tilt the balance towards independent behaviour.

Locus of Control

Locus of control (LOC) is a measurement of an individual’s sense of control over their lives.

It measures the extent to which people feel events in their lives are under their own personal control. This is internal LOC, versus under the control of external powers like fate, which is external LOC.

There is a continuum, with most people lying in between.

Internal LOC:

People with a more internal locus of control conform and obey less.

  • They take more responsibility for their actions and see themselves as having more control.
  • An internal LOC enables greater personal efficacy and self-confidence.
  • They are more likely to make decisions based on their own moral code.
  • People with a high internal LOC are more likely to be leaders, not followers.

External LOC:

People with an external locus of control believe the majority of their life events are beyond their control.

  • They are more likely to act on behalf of another (as an agent) and shift responsibility.
  •  They are particularly susceptible to obedience.
  • Externals may be more prone to learned helplessness and tend to follow others because they don’t think they can control what happens anyway.
  •  In social influence, externals are more likely to conform or obey, attributing outcomes to external pressure rather than their own agency.

Research Support (AO3)

 
Avtgis (1998) found that externals were more easily persuaded and more likely to conform than internals.
 
Holland (1967) found that 37% of internals refused to continue to the maximum shock, compared with only 23% of externals.
 

Limitations (AO3)

Rutter argued LOC only explains resistance in novel situations; prior experience usually matters more.
 
Twenge et al. (2004) found externals rose over 40 years, yet resistance to obedience also rose. That is the opposite of the LOC prediction.
 
Some candidates confuse high/low with internal/external LOC

Minority Influence

Students will be expected to know:

  • Minority influence including reference to consistency, commitment and flexibility.

Minority influence occurs when a minority group influences the majority. Minority influence is the main cause of social change: a society’s large-scale shift in its attitudes, beliefs or behaviour. It often leads to internalisation: the majority actually change their private views after being influenced, though this tends to happen gradually.

Key processes that make minority influence effective are consistency, commitment, and flexibility.

Other processes involved in minority influence and social change include:

  • Drawing attention to their beliefs, and deeper processing of the issue by the majority group
  • The augmentation principle: a risky or costly act of commitment makes a minority more persuasive
  • The snowball effect: converted individuals bring others with them until a once-minority view becomes the majority one
  • Social cryptomnesia: a society adopting a once-minority position while losing conscious memory of where the idea originally came from

Consistency

Consistency is one of three behaviours that enable a minority to influence a majority.

What Consistency Means

Minorities need to be consistent.

This has two parts: staying consistent over time (diachronic consistency) and staying consistent between members (synchronic consistency). Both parts matter.

Diachronic consistency means the minority sticks to its guns and does not modify its views.

Synchronic consistency means all members agree with each other and back each other up. Both matter equally.

For example, a minority group that repeats the same argument at every meeting, with every member saying the same thing, is highly consistent on both counts.

AQA’s specification names consistency explicitly as one of the three processes examiners expect students to describe and evaluate. Learn the two terms precisely, since exam questions sometimes ask for them by name.

Why Consistency Works

Consistency forces the majority to think deeply about the issue. The repetition and united front imply a strong, valid point.

A consistent minority causes the majority to at least reassess the issue: “They keep saying the same thing… they might have a point.”

Moscovici theorised that consistency makes majority members start to doubt themselves and take the minority view more seriously. That doubt is the point.

Confronted with a consistent opposition, the majority sits up and takes notice, because the minority has focused attention on itself.

A consistent minority also disrupts established norms, creating uncertainty and doubt that makes the majority question its own views.

However, too much consistency without flexibility can seem dogmatic.

In practice, consistency should be combined with rational argumentation. Simply repeating an assertion isn’t enough, but holding firm to a clear stance is what matters (see Flexibility, below).

Key Study: Moscovici’s Blue-Green Slide Study

  • Aim: Moscovici et al. (1969) aimed to determine the importance of consistency to a minority’s influence.
  • Method: Female participants were shown 36 blue slides of different intensity and asked to report the colour. Each group had two confederates (the minority) and four real participants (the majority).
  • Conditions: A control group had no confederates. In one condition the confederates answered “green” for all 36 slides (consistent); in the other, “green” 24 times and “blue” 12 times (inconsistent).
  • Results: When confederates were consistent, about 8% of responses were “green”, and roughly a third of participants said green at least once. With inconsistent confederates, only about 1% of responses were “green”.
  • Conclusion: A consistent minority influences the majority far more than an inconsistent one. Moscovici’s finding is often cited as the founding evidence for consistency as a key factor in minority influence.

Wood et al.’s (1994) meta-analysis of nearly 100 minority-influence studies confirmed the pattern: consistent minorities were significantly more influential than inconsistent ones.

Commitment

Minorities need to demonstrate commitment. They show resistance to social pressures and abuses against their viewpoint.

The Augmentation Principle

A minority that shows dedication to their cause, especially through personal sacrifice or suffering, is more likely to be influential.

This is explained by the augmentation principle: if the minority undergoes extreme activities or risks to further their cause, it amplifies their impact.

It shows they are not acting out of self-interest. They truly believe in their view.

For example, environmental activists who chain themselves to trees or go on hunger strikes make their commitment obvious.

This is why hunger strikes, public sacrifice, or highly visible risk-taking are such persuasive minority tactics: the cost to the individual signals the strength of their conviction.

A minority that risks nothing looks far less credible than one that visibly risks something real.

The Effect on Observers

Observers are more likely to pay attention. They ask themselves: “why would they do that unless they really have a strong point?”

High commitment can also create a sense of guilt in the majority: “perhaps our complacency is wrong if these people are willing to suffer for this.”

This works both ways.

Commitment can therefore convert more onlookers by demonstrating certainty and courage, making the minority’s message more compelling.

This is informational social influence at work.

Observers treat the minority’s willingness to suffer as evidence that their position deserves serious consideration. Over repeated exposure, this can shift bystanders from indifference to active reconsideration of their own views.

Commitment, in other words, quietly buys attention it would not otherwise get.

Flexibility

Minorities should be moderate, co-operative, and reasonable.

While consistency is vital, being inflexible and rigid can backfire.

If the minority refuses to compromise or consider alternate ideas, the majority may dismiss them as extremists or unrealistic.

Psychologist Nemeth (1986) argued that effective minorities strike a balance. They stay consistent in principle but show flexibility by adapting arguments, listening to others and making small concessions.

A flexible minority can engage the majority in dialogue.

For instance, imagine a jury where one juror argues a defendant is not guilty, but also acknowledges valid points from others and stays open to discussion. The rest of the jury are more likely to take his view seriously than if he simply repeated himself.

AO3

In short, consistency without being inflexible is key. Consistency shows commitment to the core issue, while flexibility shows an open mind.

This possibility was investigated by Nemeth (1986).

  • Aim: To test whether a minority’s flexibility, not just its consistency, makes it influential.
  • Method: In a mock jury, groups of three participants and one confederate decided on compensation for the victim of a ski-lift accident.
  • Results: A confederate who argued for a very low amount and refused to move had no effect on the majority. When he compromised, the majority also compromised and changed their view.
  • Conclusion: The minority’s change of position, not holding firm, produced the influence. This questions the importance of consistency.

Real-World Applications of Social Influence

Social influence research is used well beyond the exam hall. The clearest applications come from settings where a person is pressed to go along with a majority or an authority.

Healthcare, Uniforms and Leadership

The best-known field test of obedience outside the laboratory is Hofling et al.’s (1966) hospital study. In it, 21 of 22 nurses began to give a telephone-ordered overdose from an unfamiliar doctor. The result makes the case for teaching clinicians to question an instruction that looks wrong.

The finding is not secure, however. Rank and Jacobson (1977) published a failure to replicate it. The evidence for obedience on the ward is therefore contested.

Bickman (1974) examined the social power of a uniform in field settings. This is the real-world counterpart of the uniform variable in Milgram’s variations.

The question is whether visible markers of authority raise compliance with requests in public. It matters for security, policing and customer-service design.

Reicher and Haslam (2006) used the BBC prison study to argue that oppression becomes psychologically acceptable when groups fail.

Haslam and Reicher (2007) argued that perpetrators of atrocity act thoughtfully and with conviction rather than blindly. Both studies point training and institutional design towards group identity and leadership. They do not stop at a fear of obeying.

Social Norms, Juries and Social Change

Schultz et al. (2007) tested normative messages in a field experiment on household energy conservation. A descriptive message giving the neighbourhood average produced savings in households that used more than average.

It also produced a “boomerang” increase in households already using less. Adding a message of social approval removed the boomerang.

This is informational and normative social influence turned into policy. It shows why a message telling everyone what the majority does can backfire.

Minority influence has applications too. Nemeth (1986) used a mock-jury task to show that a minority which compromises can move a majority.

Wood et al. (1994) found minority influence strongest on private, indirect measures. That is why campaigns for change often shift attitudes before they shift public behaviour. Teams, juries and activist groups can use them directly.

Evidence Check: Does Social Influence Research Hold Up?

Verdict: Supported with qualifications.

The finding that a unanimous majority produces conformity on an unambiguous task has held up in later work. So has the finding that a large share of participants keep obeying a harmful instruction in a partial rerun of Milgram’s procedure.

What is contested is how large those effects are across time and place, and whether orders explain obedience.

Conformity Still Occurs, but the Rate Varies with Era and Culture

Level of evidence: Meta-analysis or systematic review; independently replicated.

In Asch’s line task, real participants conformed on about a third of the critical trials. That was 32% in the classic study, when the rest of the group unanimously gave a wrong answer.

Bond and Smith (1996) pooled 133 experiments. They came from 17 countries and used an Asch-type line task. The weighted mean effect size was d = 0.92 (95% CI 0.89 to 0.96). The mean error on critical trials was 29%.

Studies that strictly replicated Asch’s stimuli with confederates averaged 25% error, against the 37% they give for Asch’s own 1956 results.

Franzen and Mader (2023) reran the procedure with five confederates and one naive participant per group (N = 210). They found 33% error on the standard task.

This supports the claim that conformity to a unanimous majority on a clear perceptual task is real and replicable. It qualifies the claim in two ways.

The effect is smaller in strict replications than in Asch’s own data, and it differs by country and period. Commentators including Perrin and Spencer (1981) linked the high 1950s rates to the political climate. The classic figure is not a constant.

The line task also cannot separate private belief from public compliance. It says nothing about why people conformed.

The meta-analysis is the strongest piece of evidence, but it has limits:

  • Varied studies: The studies it pooled were heterogeneous.
  • American focus: More than two thirds of the studies were American.
  • Student samples: Only 15 used non-student samples.
  • Publication bias: The paper reports no correction for it.

Obedience Stays High in Partial Reruns, but They Stop at 150 Volts

Level of evidence: Experiment; partly replicated.

Milgram’s baseline obedience rate was 65%. Most ordinary participants kept delivering shocks under the experimenter’s instruction.

Burger (2009) ran a partial replication with 70 adults. He stopped at 150 volts, when the learner first protests.

Because 79% of Milgram’s participants who went past that point continued to the end, he could estimate what participants would have done. Obedience rates were only slightly lower than Milgram found 45 years earlier.

Doliński et al. (2017) used Burger’s procedure with added control for the sex of the participant and of the learner. They found obedience similarly high to the original studies.

Packer (2008) pooled eight of Milgram’s own experiments and found disobedience most likely at 150 volts.

The evidence supports the narrower claim that most modern adults will still go past the first protest. It does not contradict the original rate, but it does not establish the full 65% figure either.

It also says nothing about why people continue. Packer’s pooled analysis suggests a decision point at 150 volts, which sits uneasily with reading obedience as automatic.

Burger also found that watching a confederate refuse did not lower obedience. That is in tension with the social support explanation.

Burger’s rerun is the most trustworthy single piece, because it states its sampling and its estimation step openly. It still has limits:

  • Inference: Both reruns stopped at 150 volts, so the full-obedience figure is estimated, not observed.
  • Small sample: Burger’s 70 adults is small for estimating a proportion.
  • Screened volunteers: They were screened for psychological risk, which limits how far they represent the general population.

Whether Orders Drive Obedience Has Had Few Independent Tests

Level of evidence: Experiment; not yet replicated.

The classic account says obedience is explained by entering an agentic state and by the legitimacy of an authority’s orders.

Haslam et al. (2014) used an analogue paradigm, in which participants were told to use negative adjectives to describe increasingly pleasant groups. They manipulated the prods between participants.

Continuation and completion were positively predicted by how far the prods appealed to scientific goals. They were negatively predicted by how far a prod was an order.

The authors read this as consistent with engaged followership (continuing because you identify with the cause, not because you follow orders). They saw no support for the traditional obedience account.

Gonzalez-Franco et al. (2018) used a virtual-reality version with 40 participants and 20 controls. Hollander and Turowetz (2018) replied by arguing for multiple compliant processes.

The agentic-state account predicts that orders produce obedience. The one direct experimental test went the other way.

However, a single analogue by one research group cannot overturn a classic account. The question stays open. The fair reading is that the reruns support the behaviour but the explanation is contested. Students should present the agentic state as one proposed mechanism, not an established one.

The Haslam et al. experiment is the most trustworthy piece here, because it manipulated the variable directly. Its limits are clear:

  • Analogy only: The analogue task is a different task from Milgram’s, so it bears on his account only by analogy.
  • Not independent: The virtual-reality study is small and shares authors with it.

Exam Practice: Worked Past-Paper Questions

The following are real AQA A-level Psychology (7182/1) past-paper questions with their official mark schemes, used here as worked exam-technique examples.

16-Mark Extended-Writing Example (June 2020)

It is the end of the school day and Freddie is pushing other students in the bus queue. “Stop it, will you?” protests one of Freddie’s classmates. “You can’t tell me what to do!” laughs Freddie. At that moment, Freddie turns to see the deputy head, wearing a high-visibility jacket, staring angrily at him. Without thinking, Freddie stops pushing the other boys and waits quietly in line.

Discuss the legitimacy of authority and agentic state explanations of obedience. Refer to Freddie’s behaviour in your answer. [16 marks]

Marks split AO1 = 6, AO2 = 4, AO3 = 6.

It is marked on a 4-band scale, from Level 4 (13–16 marks) down to Level 1 (1–4 marks).

AO1 content: recognising a social hierarchy and its symbols (legitimacy of authority); feeling no personal responsibility for one’s own actions (agentic state); the opposite autonomous state; binding factors. That is the AO1 half.

AO2 application: Freddie is autonomous when dismissing his classmate, an equal in the hierarchy. He shifts “without thinking” into the agentic state the moment he sees the deputy head. That shift is the AO2 point.

The deputy head is a legitimate authority, made visible by the high-visibility jacket.

AO3 discussion: use evidence to support or challenge the two explanations. Milgram’s variations, Bickman’s uniform study and Hofling’s hospital study all fit here. So do real-world examples, such as the My Lai massacre.

Note that neither explanation alone accounts for the disobedience seen in some studies. Consider the dispositional alternative too.

Examiner note: methodological evaluation only counts when tied back to the two named explanations. A free-standing “this study lacked ecological validity” point earns nothing on its own.

4-Mark Short-Answer Example (June 2019)

Outline two explanations of resistance to social influence. [4 marks]

Marked AO1 = 4: two marks per explanation.

Two marks reward a clear, coherent, elaborated explanation.

One mark rewards a limited or muddled one, and zero marks go to simply naming an explanation with no reference to how it affects resistance.

Suggested content for locus of control: an internal locus means believing you control your own circumstances. Internals resist conforming or obeying more than externals do.

Suggested content for social support: non-conformity or disobedience is more likely when others are seen to resist. This gives an observer the confidence to do the same.

The mark scheme also credits other valid explanations, such as being in an autonomous state, prior experience, or reactance.

It also credits the inverse of factors that normally increase conformity or obedience. These include lack of uniform, greater distance from an authority figure, a smaller group size, or a less ambiguous task.

Key Takeaways

  • Definition: Social influence is a change in a person’s behaviour, attitudes or beliefs as a result of real or imagined pressure from others.
  • Four Areas: The AQA spec covers conformity, obedience, resistance to social influence, and minority influence.
  • Conformity: Compliance is public-only and temporary (normative influence); internalisation is public and private, and permanent (informational influence).
  • Obedience: Milgram found 65% of participants obeyed to 450V; obedience fell with distance from the authority figure and a less prestigious setting.
  • Resistance: Social support and an internal locus of control both make a person more likely to resist conforming or obeying.
  • Minority Influence: A consistent, committed, yet flexible minority can shift majority opinion, typically via internalisation.
  • Spec Currency: Identification (as a third type of conformity) and Zimbardo’s Stanford Prison Experiment are no longer examined under this topic.
  • Verdict: Supported with qualifications – the findings on conformity and obedience have held up in later work, but their size varies and the explanations are contested.

How This Topic Is Assessed

Social influence is the first compulsory topic on the AQA AS and A-level Psychology specification (7181 AS / 7182 A-level). It is examined in Section A of Paper 1: Introductory Topics in Psychology.

Paper Structure and Marks

At full A-level, Paper 1 is a 2-hour exam worth 96 marks. It has four sections, each worth 24 marks.

These are Social influence, Memory, Attachment, and Clinical Psychology and Mental Health.

The AS-only qualification is shorter: 1 hour 30 minutes, 72 marks, and only the first three sections. Clinical Psychology sits on AS Paper 2 instead.

The content itself does not change between AS and A-level. Only the paper structure does.

Each section mixes multiple-choice, short-answer and extended-writing questions. A student cannot predict the exact question format from the topic alone.

Revise all three question types for every topic, not just extended writing. Multiple-choice questions can cost easy marks just as a rushed essay can.

The Assessment Objectives

Every question tests one of three assessment objectives, shared across every exam board’s psychology specification.

  • AO1 (Knowledge): accurate knowledge of concepts, theories, studies and research methods.
  • AO2 (Application): applying that knowledge to a novel scenario or context.
  • AO3 (Evaluation): using evidence to judge a theory or study.

Across A-level Paper 1, AO1 carries roughly 11–14% of the total mark, AO2 roughly 6–9%, and AO3 roughly 12–14%.

Evaluation therefore matters as much as description. Many students lose marks by writing a long, accurate account and leaving too little time to discuss it.

Social influence questions frequently combine all three AOs in one extended-writing question. A strong answer weaves knowledge, application and evaluation together, rather than as separate paragraphs, and revisits the scenario throughout.

How Extended-Writing Questions Are Marked

Extended-writing questions are typically worth 16 marks at A-level, 12 at AS. They are marked on a 4-band levels-of-response scale, not a tick-list.

A top-band answer combines detailed knowledge with effective application and thorough discussion. It uses specialist terminology correctly throughout.

A Level 1 answer, by contrast, shows only basic, muddled knowledge with little attempt at application or discussion.

Most students sit between the two extremes. Sustaining Level 4 quality throughout a whole answer, not just the opening paragraph, separates the strongest scripts.

One examiner note applies across AQA’s published mark schemes. Methodological evaluation only earns credit when it is explicitly linked back to the point being discussed.

Simply writing “low ecological validity” caps the mark on its own. Saying what that limitation means for the explanation being discussed does not.

The Two-Sentence Technique for AO2

Scenario questions reward a simple pattern. State the relevant psychological knowledge in one sentence.

Then add a second sentence naming the specific detail from the scenario it explains.

For example: “Normative social influence is conforming to be liked or avoid rejection. This is shown by Freddie, who stops pushing once he sees the deputy head, a shift driven by wanting to avoid the disapproval of a visible authority figure.”

Quoting a short phrase directly from the scenario is rewarded. So is linking language such as “this suggests that…”.

Restating the scenario without naming the mechanism it illustrates earns no application credit. This same two-sentence pattern works for any AO2 question across the specification, so it is worth practising until it feels automatic.
