COM5101 Chap.9 Balance, Norms and Group Dynamics
Balance, Norms and Group Dynamics
Balance theory adds a third relation
Balance theory represents relations among a person, another person and an object. Positive and negative ties can create a coherent pattern or an unbalanced pattern that produces pressure for change.
The model turns a simple disagreement into a relational structure: changing an attitude, changing a relationship or reinterpreting another person's position can each restore balance.
Tension does not identify its endpoint
An unbalanced triangle does not reveal which tie will move. A valued relationship can encourage attitude change, while a core value can make distance from the other person more likely.
Ambiguous evidence can be reinterpreted so that no durable tie changes. Power, commitment and available alternatives help rank these routes.
Groups differ in relational function
The lecture distinguishes primary, reference and casual groups. Primary groups involve enduring intimate relations. Reference groups provide standards for attitudes and behaviour. Casual groups form temporarily.
The category matters because the cost of disagreement and the relevance of a norm differ across these relationships.
Norms and values operate at different levels
A norm is a relatively specific accepted rule or convention. A value is a broader, longer-term system of belief that can organise several norms. Both are inferred from behaviour, but frequency alone is weak evidence.
Correction, sanction, justification and reactions to deviation reveal that a rule is socially expected.
Mechanism must connect the group to change
Describing a norm does not explain conformity. The analyst should specify whether uncertainty, belonging, sanction, information or identity makes the norm influential.
This connects group dynamics back to theory construction and keeps application from becoming a list of group labels.

Key terms
- Balance Theory
- A model of positive and negative relations among a person, another person and an object.
- Primary Group
- A group characterised by enduring, intimate and often face-to-face relationships.
- Reference Group
- A group used as a standard for attitudes and behaviour even without intimate membership.
- Group Value
- A broad and durable system of beliefs that can organise several more specific norms.
Balance, Norms and Group Dynamics FAQ
Does an unbalanced triangle predict which tie will change?
No. It predicts pressure toward coherence, not the endpoint. Attitude, relationship or interpretation may change. Rank the possibilities using commitment, value centrality, power and ambiguity. A finished analysis identifies evidence that would show which route occurred rather than fitting one story afterwards.
How is a group norm different from a value?
A norm is a relatively specific accepted rule or convention, while a value is broader, more durable and capable of organising several norms. Look for correction, sanction and justification to support a norm claim. Behavioural frequency alone may reflect convenience or selection rather than social expectation.
Why does group type matter in an application?
Primary, reference and casual groups create different relational stakes. A reference group can guide attitudes without intimate contact, while a casual group may impose weak long-term costs. Identifying group type helps explain why a norm influences behaviour and which form of change is plausible.
What is the best evidence that a norm exists?
Repeated behaviour is a start, but reaction to deviation is stronger evidence. Correction, sanction or justification shows that members treat the behaviour as expected. Compare this with practical constraint and self-selection before concluding that a shared norm produced the regularity.
Assessment move
Draw signed triangles for original cases and list all three repair routes before choosing one. Add evidence beside each tie so that the model remains testable. For group concepts, keep separate cards for group type, norm, value and mechanism. Practise turning observed regularity into competing explanations: shared value, explicit sanction, practical constraint or self-selection.
In quiz answers, avoid saying that balance theory proves attitude change. State that it predicts tension and use case evidence to rank possible changes. For the paper, compare studies by how they operationalise each relation. Run a before-and-after triangle exercise.
Sign each tie before a disagreement becomes salient, predict which tie is easiest to change, then identify the observation that would show attitude change, relationship change or reinterpretation. This keeps the account from being fitted after the outcome. For norms, collect three kinds of evidence: repeated behaviour, reaction to deviation and the reason members give for correction.
The last two distinguish social expectation from convenience. Then ask whether the justification invokes a broader value. This lets you move from behaviour to norm and value without collapsing the levels.
