Formation of Groups

Campbell (1963) proposed that groups pass through five stages:

Stage 1 - Forming (Uncertainty)

• People meet, share interests, and evaluate mutual benefit.
• Positive evaluation → group forms; no evaluation → group disintegrates.​

Stage 2 - Storming (Intra-group Conflict)

• Members debate goals; differences of opinion cause conflict.
• If conflict is resolved, the group continues; if unresolved, the group disintegrates.​

Stage 3 - Norming (Closeness & Cohesiveness)

• Members grow closer; a group bond is formed.
• Agreed-upon norms and values are created → a group is formed.

Stage 4 - Performing (Full Functionality)

• The group becomes fully functional; members carry out assigned tasks.
• Activities are evaluated regularly; the group achieves its goal.​

Stage 5 - Adjourning (Wrapping Up)

• The goal is achieved; group activities are wrapped up.
• The group formally dissolves; members are free from obligations.

​Groups do not always follow these stages in order—they may overlap, skip, or revert.

Six key factors help groups form:

• Proximity – People who are physically close interact more and discover shared interests, leading to group formation.​
• Similarity – People with similar personalities, attitudes, and interests come together because they validate and reinforce each other.​
• Common Goals – Shared objectives bring people together; most informal groups develop due to common goals.​
• Attractiveness – Attraction to other members, group activities, or the group as a means to personal goals facilitates formation.​
• Amount of Effort – Hard-to-join groups form slowly but last longer; easy-to-join groups form quickly but break up easily.​
• External Threats- Common threats like natural calamities or war rapidly unite people into groups.​

Three theories explain why humans prefer group life:​

Instinct Theory (Freud, Lorenz)

• Humans are biologically programmed to form groups.
• Freud's Eros (constructive) and Thanatos (destructive) instincts find expression in groups.
• Lorenz proposed an inherited sense of belongingness shared with other species.​
• Criticism: Uses circular reasoning; cannot explain cross-cultural variation in group behaviour.​

Biological Theory (Moreland)

• Long childhood dependency keeps humans in primary groups (family) for basic needs.
• This creates a lifelong tendency to seek group membership.​
• Higher dependency in child-rearing → stronger need for group affiliation (Moreland, 1987).​

Role Theory

• People join groups to fulfil the social roles assigned to them.
• Based on the division of labour (traditional) and the specialisation of skills (modern).

• Roles are socially defined expectations that individuals in a given situation are expected to fulfil.
• Roles refer to the typical behaviour that depicts a person in a given social context.

People join groups to satisfy different needs:

• Security — Groups reduce insecurity and make people feel stronger and protected.
• Status — Membership in an important group brings recognition and a sense of power.
• Self-Esteem — Groups provide self-worth and a positive social identity.
• Psychological & Social Needs — Groups satisfy belongingness, love, attention, and power needs.
• Goal Achievement — Some goals cannot be attained alone; groups multiply collective capacity.
• Knowledge & Information — Groups broaden individual knowledge by sharing information.​

Four elements make up group structure:

• Roles – Socially defined expectations about how a person in a given position should behave (e.g., a student is expected to study and respect teachers).
• Norms – The group's unspoken rules; agreed-upon standards of behaviour shared by all members.
• Status – The relative social position of a member; can be ascribed (by seniority) or achieved (by expertise).
• Cohesiveness – The "we feeling" or team spirit; highly cohesive groups are hard to leave and hard to enter.

Status refers to the relative social position given to group members by others.

• Cohesiveness refers to togetherness, binding, or mutual attraction among group members.
• Cohesiveness refers to the team spirit or ‘we feeling’ or a sense of belongingness to the group.

Irving Janis identified groupthink as a process where a group's desire for unanimity overrides realistic decision-making:

• No one expresses disagreement for fear of being unpopular or disrupting group harmony.
• The group develops an exaggerated sense of its own power and ignores real-world warnings.
• Groupthink is most likely in cohesive, homogenous, isolated groups under high pressure.​

Example: During the Vietnam War (1964–67), President Johnson's advisors suppressed dissent, leading to a catastrophic escalation that cost 56,000+ American and 1 million+ Vietnamese lives.

Prevention:

• Encourage critical thinking and disagreement among members.​
• Always consider alternative courses of action.
• Invite outside experts to review decisions.
• Seek feedback from trusted people outside the group.​

• Five-Stage Model of Group Formation – Groups pass through five stages: forming, storming, norming, performing, and adjourning.
• Factors for Group Formation – Proximity, similarity, common goals, and external threats influence group formation.
• Group Cohesiveness – High cohesiveness strengthens unity, but excessive cohesiveness can lead to groupthink, where critical thinking is suppressed.
• Reasons for Joining Groups – People join groups for security, status, self-esteem, goal achievement, and psychological/social needs.
• Instinct & Biological Theories – Humans have an innate need for belonging, which drives group formation.
• Role Theory – People join groups to perform specific roles and contribute to group goals through division of labour.
• Stages of Group Development – Groups develop through forming, storming, norming, performing, and adjourning, with group norms and cohesiveness influencing behaviour.
