Key takeaways

  • Social support helps people resist because a dissenter or disobedient peer breaks the group's unanimity and models independent behaviour; in Milgram's variation with a disobedient peer, obedience to 450V fell to 10%.
  • Locus of control is how far a person feels they control their own life; people with an internal locus of control tend to resist social influence more than those with an external locus.
  • Minority influence typically causes internalisation (a genuine, private conversion), which makes it deeper and more lasting than majority-driven compliance.
  • A minority is more persuasive when it is consistent, committed and flexible; Moscovici's blue-green slide study showed a consistent minority influenced the majority far more than an inconsistent one.
  • The snowball effect describes how, as more individuals convert to the minority view, that view gradually spreads until it becomes the new majority position.

Two Ways People Resist Social Influence

Most of the social influence topic explains why people give in to a group or an authority figure. This lesson covers the opposite: how some people hold out. AQA names two explanations of resistance to social influencesocial support and locus of control — and you must be able to describe and evaluate both.

Resistance to social influence means the ability to withstand pressure to conform to a majority or to obey an authority figure. It is not the same as never feeling the pressure; it is being able to act independently despite it.

ExplanationType of factorCore idea
Social supportSituationalOthers who resist make it easier for you to resist
Locus of controlDispositionalA personality trait affecting how much you resist

Keeping these apart matters. Social support is about the situation you are in, while locus of control is about the kind of person you are. Many exam questions ask for one specifically, so learn which is which.

Resistance is the capacity to act independently of the majority or an authority figure. Social support explains it through the situation; locus of control explains it through personality.

Social Support: Breaking the Unanimity

Social support is the presence of other people who also resist the pressure. When someone else refuses to go along with the group, it becomes much easier for you to do the same. The key is that they break the group's unanimity and act as a model for independent behaviour.

Social support works differently in the two situations you must know:

Resisting conformity. In Asch's line-judgement study, adding a dissenter — a confederate who did not conform to the wrong majority answer — sharply reduced conformity. Importantly, the dissenter's answer did not even have to be correct. Simply having someone break away from the unanimous majority freed the genuine participant to give their own answer. The dissenter shows that disagreement is possible and that the majority is not all-powerful.

Resisting obedience. In one of Milgram's variations, the real participant was paired with two confederate "Teachers" who refused to continue and withdrew from the study. With these disobedient peers modelling dissent, obedience to the full 450 volts dropped to 10%, compared with 65% in the baseline study. A disobedient peer provides a model of dissent and makes the authority figure appear less legitimate.

SituationSource of supportEffect on the participant
ConformityA dissenting (non-conforming) confederateConformity falls sharply
ObedienceDisobedient confederate "Teachers"Obedience to 450V falls to about 10%

The dissenter does not have to be right. What matters is that they break the majority's unanimity, which is enough to release others to resist.

Locus of Control: An Internal-External Scale

Locus of control, proposed by Rotter in 1966, refers to how much people feel they are in control of the events in their own lives. It is measured on a continuous scale running from a high internal locus of control at one end to a high external locus of control at the other.

Internal locus of control. People with an internal locus of control believe they are largely responsible for what happens to them. Their choices and effort determine outcomes. These individuals tend to resist pressure more, because they are typically more self-confident, more achievement-oriented, and have less need for social approval.

External locus of control. People with an external locus of control believe that what happens to them is determined by outside forces such as luck, fate, or powerful others. Feeling less in control of their own outcomes, they tend to be less resistant to social influence.

Locus of controlBelief about outcomesTendency to resist
Internal"I am responsible for what happens to me"Higher
External"Luck, fate or others control my life"Lower

The direction to memorise: internals resist more. They are more self-assured and less dependent on others' approval, so they find it easier to stand against a majority or an authority figure.

Minority Influence: When the Few Change the Many

Minority influence is a form of social influence in which a small number of people, or even a single person, changes the beliefs or behaviour of the majority. This is the reverse of conformity, where the majority pulls the individual in.

The crucial difference from majority influence is the type of change it produces. Minority influence typically leads to internalisation — a genuine, private change of view often described as conversion. Because the person is persuaded to actually rethink and privately accept the new position, the change is deeper and more durable than the compliance usually produced by a majority, where only public behaviour shifts.

According to Moscovici, three behaviours make a minority influential. Remember them as the three Cs, with flexibility as the third:

FactorWhat it meansWhy it works
ConsistencyThe same message over time and between membersMakes the majority rethink their own view
CommitmentDedication, sometimes through personal riskDraws attention via the augmentation principle
FlexibilityWillingness to adapt and accept fair pointsAvoids appearing rigid and dogmatic

Minority influence produces internalisation (a private conversion), not compliance. This is the single most tested distinction on this topic.

The Three Behaviours in Detail

Each of the three factors earns marks in its own right, so learn what makes each one distinct.

Consistency means the minority keeps the same message. There are two forms: diachronic consistency (staying consistent over time) and synchronic consistency (all members of the minority saying the same thing as each other). A consistent minority is harder to dismiss and forces the majority to stop and reconsider their own position.

Commitment means the minority demonstrates real dedication to its cause, sometimes by taking a personal risk or making a sacrifice. This engages the augmentation principle: when a minority is prepared to suffer or take a risk for its view, the majority assumes the view must be strongly held and takes it more seriously.

Flexibility was emphasised by Nemeth, who argued that being completely consistent can tip over into looking rigid and dogmatic. A minority is more persuasive when it is prepared to adapt its position and accept reasonable counter-arguments, rather than refusing to shift at all. The skill is balancing consistency with a willingness to negotiate.

Once a minority starts to persuade people, the snowball effect can take over: as more and more individuals convert to the minority view, it gradually gathers momentum until it becomes the majority position.

Consistency and flexibility sound contradictory but are not. Consistency is about the core message; flexibility is about being reasonable in how you argue it. Nemeth's point is that rigid consistency can backfire.

Moscovici's Blue-Green Slides Study (1969)

Moscovici et al. carried out the classic demonstration that consistency drives minority influence. The study is the key piece of evidence you should be able to describe.

Method. Groups of six people were shown a series of 36 blue slides, each a slightly different shade of blue, and asked to state aloud the colour of each slide. In each group, two of the participants were confederates — the minority. In one condition the confederates consistently called every slide "green"; in another they were inconsistent, calling the slides green on two-thirds of trials and blue on the rest.

Findings. When the minority was consistent, the real participants agreed that the slides were green on about 8.42% of trials. When the minority was inconsistent, agreement fell to about 1.25% of trials.

Minority conditionParticipants answering "green"
Consistentabout 8.42% of trials
Inconsistentabout 1.25% of trials

Conclusion. A consistent minority is far more influential than an inconsistent one. Although 8.42% may look small, it is a meaningful effect given that the majority answer (blue) was obviously correct, and it shows a minority can shift the views of a majority when it stays consistent.

Moscovici's study is the go-to evidence for consistency. The consistent minority had over six times the influence of the inconsistent one, supporting Moscovici's claim.

Evaluation (AO3)

Describing these theories earns AO1 marks; the higher marks come from evaluating them. Cover a mix of strengths and limitations across both strands.

Research support for consistency. Moscovici's blue-green study directly supports the claim that consistency matters, and Wood et al. conducted a meta-analysis of almost 100 studies which found that minorities seen as consistent were the most influential. This convergence of evidence strengthens the argument that consistency is central to minority influence.

Support for deeper, internalised processing. Martin et al. presented participants with a message and later exposed them to a conflicting view. Participants were more resistant to the conflicting view when the original message had come from a minority than from a majority. This suggests minority positions are processed more deeply, supporting the idea that minority influence produces genuine internalisation rather than surface compliance.

Mixed evidence on locus of control. Support for the role of locus of control is not clear-cut. Twenge et al. found that over time people have become more external in their locus of control, yet also more resistant to obedience. If internals resist more, these two trends should move together, so this finding challenges the proposed link. Rotter himself noted that locus of control only strongly predicts behaviour in new situations, which limits how far it explains resistance in familiar ones.

Artificial tasks limit real-world value. Much minority-influence research relies on artificial tasks such as identifying the colour of a slide. These lack the emotional stakes and consequences of real social change, so the studies have limited ecological validity. We should be cautious about generalising from a lab task about slide colours to how minorities bring about genuine change in society.

A strong evaluation weighs research support (Moscovici, Wood, Martin) against methodological limits (artificial tasks) and mixed findings (Twenge on locus of control), rather than listing points one-sidedly.

Common Exam Mistakes

1. Getting the locus of control direction backwards

Internals resist social influence more, not less. It is easy to muddle, but the person who believes they control their own life is the one who stands firm. Externals, who feel controlled by luck or others, tend to give in more readily.

2. Saying minority influence produces compliance

Minority influence produces internalisation (a genuine private conversion), not compliance. Compliance — a shallow, public-only change — is the outcome typically linked to majority influence. Reversing this loses easy marks.

3. Confusing consistency, commitment and flexibility

These are three separate factors. Consistency is keeping the same message; commitment is showing dedication or personal risk (the augmentation principle); flexibility is being willing to adapt. Do not blur them into one vague point about "being persuasive".

4. Assuming social support must be correct to work

In Asch's variations, the dissenter reduced conformity even when their answer was also wrong. What matters is that they break the majority's unanimity, not that they give the right answer. Saying support only works if it is correct is a common error.

5. Treating locus of control as fixed and universal

Locus of control lies on a scale, not two rigid boxes, and Rotter noted it mainly predicts behaviour in new situations. Presenting it as an absolute personality type that always determines resistance overstates the evidence.

Key terms

Social support
The presence of one or more people who resist pressure to conform or obey, which breaks the group's unanimity and makes it easier for others to resist too.
Locus of control
A person's perception of how much control they have over events in their life, measured on a scale from high internal (self-determined) to high external (determined by luck, fate or others).
Internal locus of control
The belief that you are responsible for what happens to you; associated with greater resistance to social influence.
External locus of control
The belief that events are controlled by outside forces such as luck, fate or powerful others; associated with less resistance to social influence.
Minority influence
A form of social influence in which a small number of people, or one person, changes the beliefs or behaviour of the majority, typically producing internalisation.
Consistency
A minority keeping the same message over time (diachronic) and between its members (synchronic), which makes the majority rethink their own position.
Commitment
A minority demonstrating dedication to its cause, sometimes through personal sacrifice or risk, which makes the majority take it more seriously (the augmentation principle).
Flexibility
A minority being prepared to adapt its position and accept reasonable counter-arguments, rather than being rigid and dogmatic.

Frequently asked questions

People with an internal locus of control resist more. They believe they are responsible for what happens to them, tend to be more self-confident and less reliant on social approval, so they are better able to withstand pressure from a majority or an authority figure.

Minority influence typically leads to internalisation, a genuine private change of belief often called conversion. This makes it deeper and more durable than the compliance usually produced by majority influence, where only public behaviour changes.

Consistency (keeping the same message over time and between members), commitment (showing dedication, sometimes through personal risk or sacrifice) and flexibility (being willing to adapt and accept reasonable counter-arguments rather than being rigid).
