The Nature of Groups
A group is more than just a collection of people; it is an organised system of interaction and interdependence.
A group is defined as an organised system of two or more individuals who are interacting and interdependent, have common motives, have a set of role relationships among its members, and have norms that regulate the behaviour of its members. Unlike a crowd, which is a chance collection of people (like spectators at an accident), group members are interdependent. This means the actions of one member have direct consequences for others, such as a fielder dropping a catch in a cricket match affecting the whole team's score.
Teams are special kinds of groups where members often have complementary skills and are committed to a common goal or purpose. In a team, members are mutually accountable for their activities and achieve positive synergy through coordinated efforts. In contrast, in a general group, performance is often dependent on individual contributions, and the leader typically holds the primary responsibility for the work.
| Feature | Group | Crowd |
|---|---|---|
| Structure | Organised with roles and norms | Lacks formal structure |
| Interdependence | High; members depend on each other | Low or none |
| Belongingness | Strong sense of 'we-feeling' | No feeling of belongingness |
| Behaviour | Rational and goal-directed | Often irrational or impulsive |

Why Do People Join Groups?
Human beings are social animals who join groups to satisfy various psychological and social needs.
One of the primary reasons for joining a group is security. Being part of a collective reduces feelings of insecurity and provides a sense of protection and comfort. Groups also provide status; being a member of a group perceived as important by others makes an individual feel recognised and powerful. For instance, being part of a winning school debate team enhances one's social standing.
Groups also bolster self-esteem by providing a positive social identity. Membership in prestigious groups enhances an individual's self-concept. Additionally, groups satisfy social needs like belongingness, love, and the desire to give and receive attention. They also facilitate goal achievement, allowing individuals to accomplish tasks that would be impossible to do alone. Finally, groups provide knowledge and information, broadening an individual's perspective by supplementing what they know with the collective knowledge of the group.

Factors Facilitating Group Formation
Groups do not form randomly; specific social conditions facilitate the interaction between individuals.
Proximity is a major determinant of group formation. Repeated interactions with people living in the same colony or attending the same school provide opportunities to discover common interests. Similarity is another key factor; people prefer consistency and are drawn to those who share their attitudes and values. When we meet similar people, they validate our opinions, making us feel 'right' and increasing our liking for them.
Common motives and goals also bring people together. When individuals realise they share a specific objective—such as cleaning up a local park—they form a group to facilitate the attainment of that goal. This collective effort allows for the pooling of resources and energy that an individual acting alone could not provide.

Tuckman's Stages of Group Formation
Groups are dynamic entities that evolve through a series of developmental sequences.
Psychologist Bruce Tuckman suggested that groups pass through five stages: Forming, Storming, Norming, Performing, and Adjourning. In the 'Forming' stage, members first meet and experience uncertainty about the group's goals. This is followed by 'Storming,' a period of intragroup conflict where members compete for roles and disagree on how to achieve targets.
Once conflict is resolved, the group enters the 'Norming' stage, where standards of behaviour are established and a positive group identity develops. In the 'Performing' stage, the group structure is settled, and members work effectively toward their goals. Finally, for temporary groups like a school function committee, the 'Adjourning' stage occurs when the task is finished and the group is disbanded.
The Five Stages of Group Development
- 1
Forming
Initial meeting; high uncertainty about goals and fit.
- 2
Storming
Intragroup conflict over leadership, tasks, and resources.
- 3
Norming
Development of group norms and a cohesive social identity.
- 4
Performing
The group structure is accepted and focused on goal achievement.
- 5
Adjourning
The group disbands after the task or function is completed.
Tuckman's model shows the typical progression of a group from its initial meeting to its eventual dissolution.

Elements of Group Structure
As members interact, they develop a structure consisting of roles, norms, status, and cohesiveness.
Roles are socially defined expectations for individuals in specific positions, such as the role of a student or a parent. Norms are the agreed-upon standards of behaviour that act as 'unspoken rules' for the group. Status refers to the relative social position given to members, which can be 'ascribed' (based on seniority) or 'achieved' (based on expertise).
Cohesiveness is the 'we-feeling' or the degree of mutual attraction among members. Highly cohesive groups have members who are strongly motivated to stay in the group. However, extreme cohesiveness can lead to 'Groupthink,' where the desire for unanimity overrides the realistic appraisal of different courses of action, often leading to irrational decisions.

Major Types of Groups
Groups can be classified based on their formation, structure, and the nature of member relationships.
Primary groups (like family or religion) are pre-existing formations that are central to an individual's values and involve face-to-face, emotional bonds. Secondary groups (like political parties) are joined by choice and involve more impersonal, indirect relationships. Formal groups have explicitly stated functions and rules (like a university), while informal groups (like a group of friends) are based on close personal relationships rather than laws.
Ingroups and outgroups are based on social categorisation. The 'ingroup' is the group one belongs to ('we'), while the 'outgroup' refers to others ('they'). People generally view their ingroup members more favourably and perceive outgroup members as different or even negative. Tajfel's 'Minimal Group Paradigm' experiments showed that people favour their own group even when the groups are formed on trivial criteria, like a preference for a specific artist.

Social Loafing: Reduced Effort in Groups
Social loafing occurs when individuals exert less effort in a group than they would when working alone.
When individual outputs are pooled into a collective task, such as a game of tug-of-war, it becomes difficult to identify the specific contribution of each member. This leads to social loafing, where individuals become 'free riders.' Experiments by Latane and his associates demonstrated this by asking male students to clap or cheer as loudly as possible. They varied the group size, having individuals work alone or in groups of two, four, and six.
The results of Latane's study showed that although the total amount of noise rose as group size increased, the amount of noise produced by each participant dropped. This happens because members feel less personally responsible for the outcome and realise their individual efforts won't be specifically evaluated. To reduce social loafing, group leaders can make individual efforts identifiable, increase the perceived importance of the task, or strengthen group cohesiveness.

Group Polarisation
Group interaction often leads to the strengthening of the group's initial position, a phenomenon known as group polarisation.
Groups are more likely to take extreme decisions than individuals acting alone. If a group initially leans toward a particular view, discussion within the group often makes that view even stronger. For example, if a group is deciding on a punishment for an unethical act, they might move toward a much harsher or much more lenient decision than any single member would have chosen initially.
Polarisation occurs for three main reasons. First, members hear new arguments that support their existing views. Second, seeing others share the same view creates a 'bandwagon effect' that validates the opinion. Third, as people identify with the 'ingroup,' they conform to the group's perceived norms, which further strengthens their convictions.
