Definition of Pressure Group
Definition of Pressure Group

There are several groups in the political system which attempt to influence the political process. Apart from political parties, pressure groups are also important in this respect. The study of pressure groups has its origin in the “group theory” of politics. This theory emphasizes that the group rather than the individual is central to the study of politics. The major concern of government, therefore, is the adjustment or balance of group interests. The first systematic study of pressure groups was by Arthur Bentley (1908), a famous English writer. There has since then a been great deal of interest in the study of pressure groups.

What Does Pressure Group Actually Mean?

There is a lot of confusion about the meaning of pressure group. As such, various towns such as – pressure group, interest group, attitude group or political group have been used to describe the same phenomenon. Some writers disagree with the use of the term “pressure group” because it is not every group that uses pressure to achieve its objectives, and even if it does, it does so intermittently.

Many writers even see it as a term of abuse and not a neutral description because there is this suspicion of a group attempting to subvert the processes of representative government through dark and secretive intrigues. This partly explains the deep-rooted suspicion of labour unions and other pressure groups by political leaders.

In spite of this disagreement about terminology, the term pressure group has come to stay. It has come to stick like a sore thumb.

Definition of Pressure Group

A pressure group may simply be defined as an association of individuals whose main objective is to influence government in a manner favourable to the interest of its members.

Unlike political parties, a pressure group has no interest in becoming the government. Rather pressure groups are organised groups seeking to achieve defined goals.

Classification of Pressure Groups

Pressure groups may be classified into two categories depending on the types of goals they pursue. These are the interest groups and attitude groups. The interest groups is otherwise known as a protective groups. As the name implies, the interest group usually protects the interests of a section of the society. In other words, its membership is limited to a part of the society. Examples of pressure groups in this category are professional and labour associations.

On the other hand, the promotional or attitude groups promote a particular cause, which may be of interest to the whole society. The members of this group hold certain values in common. They may be concerned about smoking, child trafficking or examination malpractice. The Royal Society for the Prevention of Cruelty to Animals, for example, campaigns against all forms of cruelty to animals.

These two classes of pressure groups are very important to our understanding of the topic but this is not to say that the classification has no problem of its own. it is difficult, for instance, to draw a line between defending an interest and promoting an interest. In the game of football, for example, there are defenders and attackers. But nowadays, defenders do score goals and the two full back players (now called wing backs) are even encouraged by coaches to join the attack. The attackers also help to defend when necessary. In spite of this however, the primary role of the defenders to defend while that of the attacker is to score goals. Similarly an interest group protects or defends an interest while an attitude group primarily promotes a cause. It is therefore difficult to separate one from the other.
