The Emotional Drive: NSI is based on the human desire for social approval and the fear of rejection or ridicule. It is an emotional process where individuals conform to the 'norms' of a group to fit in and be accepted, even if they personally disagree with the group's actions.
Situational Triggers: NSI is most likely to occur in unambiguous situations where the correct answer is clear, but the social pressure to agree is high. It is particularly strong in the presence of friends or peers where the cost of social exclusion is perceived as high.
Outcome - Compliance: Since the motivation is social rather than intellectual, NSI typically leads to compliance. This is a superficial and temporary change where the individual agrees with the group in public but maintains their original private beliefs.
| Feature | Informational Social Influence (ISI) | Normative Social Influence (NSI) |
|---|---|---|
| Primary Goal | To be accurate/correct | To be liked/accepted |
| Type of Process | Cognitive (Rational) | Emotional (Social) |
| Situation | Ambiguous or novel | Unambiguous or social |
| Resulting Type | Internalisation | Compliance |
| Duration | Permanent/Long-term | Temporary/Short-term |
Internal vs. External: ISI changes the internal mindset of the individual, whereas NSI primarily changes the external behavior to satisfy social demands.
Ambiguity vs. Clarity: ISI relies on the lack of clarity in a task to gain power, while NSI can exert power even when the task is perfectly clear and the individual knows the group is wrong.
Task Difficulty: As a task becomes more difficult or the correct answer becomes more obscure, the reliance on ISI increases. Individuals are more likely to look to others for information when they lose confidence in their own judgment.
Group Size: The strength of NSI generally increases with the size of the majority, though this effect levels off after the group reaches a certain size (typically 3-4 people).
Unanimity and Social Support: The presence of just one other person who disagrees with the majority (a 'dissenter') drastically reduces the power of NSI. This provides the individual with social support, making them feel less isolated and more able to resist the pressure to conform.
Identify the Motivation: When analyzing a scenario, always ask: 'Is the person conforming because they are confused (ISI) or because they are afraid of being the odd one out (NSI)?'
Check for Private Change: Look for clues about whether the person continues the behavior when they are alone. If they do, it is likely ISI leading to internalisation; if they stop, it is NSI leading to compliance.
Link to Task Type: Remember that ambiguous tasks (like estimating a distance in the dark) favor ISI, while clear tasks (like matching line lengths) favor NSI.
Evaluate Individual Differences: Be prepared to discuss how some people are more 'nAffiliators' (have a greater need for social relationships) and are thus more susceptible to NSI than others.
Mutual Exclusivity: A common mistake is assuming a situation involves only ISI or only NSI. In many real-world social interactions, both processes operate together to influence behavior.
Confusing Outcomes with Explanations: Do not confuse the explanation (ISI/NSI) with the type of conformity (Internalisation/Compliance). ISI is the reason why someone conforms; internalisation is the result of that influence.
Overstating NSI in Private: Students often incorrectly suggest that NSI leads to a change in private opinion. NSI is specifically about public face-saving; the private opinion usually remains unchanged.
