Pressure groups — also called interest groups — are organised associations that try to shape public policy in their favour while deliberately staying out of the contest for office. Their defining characteristic is this combination of influence without responsibility: they seek to affect what governments do, but because they never have to assemble a majority or answer to an electorate, they can pursue a single interest single-mindedly.
Two boundaries fix the concept. A political party seeks to capture governmental power, must therefore aggregate many interests into a programme, and accepts electoral accountability; a pressure group articulates one interest and bargains with whoever holds power. A social movement is broader, looser and more change-oriented, relies on extra-institutional action and often lacks formal membership, whereas a pressure group typically has a register, a subscription, an office and a preference for negotiation. The boundaries leak in both directions: movements spawn organisations that settle into lobbying, and groups denied access resort to agitation.
Sectional and promotional groups
The standard classification turns on whom the group speaks for. Sectional, protective or interest groups represent the material interests of a defined section of society and recruit from it — chambers of commerce, trade unions, farmers' organisations, medical and bar associations. Their membership is closed, their demands are distributive, and their strength lies in the indispensability of what their members do.
Promotional or cause groups pursue a value or a public good and are open to anyone who shares it — civil liberties bodies, environmental campaigns, anti-corruption movements, animal welfare organisations. Their members are not usually the beneficiaries, which is why they depend on conscience support and on publicity rather than on the threat of withdrawal. Sectional groups tend to be better funded and better connected; promotional groups tend to be better at moral argument. Olson's analysis explains the asymmetry: concentrated interests organise more easily than diffuse ones.
Insider and outsider status, and methods
A second, more analytically useful distinction concerns a group's relationship to the state. Insider groups are consulted as a matter of course, sit on advisory committees, supply technical evidence and are trusted to be discreet; the price of access is moderation, since a group that embarrasses officials loses its seat. Outsider groups either cannot obtain such access or refuse it on principle, and must therefore work through public opinion.
The methods follow from status. Insiders use lobbying — private representation to ministers, legislators and civil servants — along with technical submissions, expert committees, drafting assistance and the funding of research. Outsiders use publicity and media campaigns, petitions, demonstrations, dharnas and hunger strikes. Between the two lies litigation, which has become central where courts are activist, and electoral pressure, through endorsements, funding and the mobilisation of a voting bloc. The strongest weapon of a sectional group is economic sanction: the strike, the lockout, the withholding of investment, the refusal to bring produce to market.
Pluralist, elite and corporatist accounts
Three theories interpret the same activity very differently. The pluralist account, associated with David Truman and Robert Dahl, sees group competition as the substance of modern democracy: interests are multiple and cross-cutting, no group wins everything, potential groups discipline the powerful even before they organise, and government arbitrates. Elite theory replies that the arena is rigged. As Schattschneider put it, the pressure system has an upper-class accent — organisation itself is a resource distributed unequally, so business is heard while the unorganised poor are not, and the range of issues admitted to the agenda is narrowed in advance. Corporatist accounts, following Philippe Schmitter, note a third possibility: instead of competing for influence, a small number of peak associations of capital and labour are licensed by the state, given a monopoly of representation, and incorporated into policy-making in exchange for disciplining their own members. Here the group is less a pressure on the state than an instrument of it.
The Indian landscape
India's group universe is dense and lopsided. Business is represented by long-established chambers — FICCI, ASSOCHAM and the CII — which enjoy classic insider access through consultation on budgets and industrial policy. Trade unions are numerous but fragmented and largely tied to political parties, which gives them political voice while limiting their independence, and they organise only the small formal segment of the workforce. Farmers' organisations have oscillated between insider bargaining over procurement prices and mass agitation on roads and mandis. Caste associations occupy a distinctively Indian place: Rajni Kothari and the Rudolphs showed how jati bodies transformed themselves into vehicles for educational, occupational and political claims, mediating between traditional identity and modern representation. Professional bodies — bar councils, medical associations, officers' associations — defend entry, pay and autonomy with considerable success, and since the 1990s NGOs and advocacy networks have used public interest litigation, right to information and media campaigns to become influential without any mass base at all.
The recurring criticism is the skew of access. Groups representing organised, urban, literate and propertied interests are consulted; agricultural labourers, construction workers, domestic workers, forest dwellers and the informally employed — the overwhelming majority — are represented, if at all, by others speaking on their behalf. Party-linked unions, personalised leadership, opacity in funding and the absence of any statutory regulation of lobbying compound the problem, so that group politics in India tends to reproduce rather than correct existing inequalities of voice.
For the UPSC answer
Define the group by what it does not do — it does not seek office — and use that to separate it from parties and from movements in a single sentence each. Deploy both classifications, sectional versus promotional and insider versus outsider, and tie the methods to the second of these. The theoretical core of a good answer is the three-way contrast between pluralist, elite and corporatist readings, with Schattschneider's upper-class accent as the pivot. Illustrate with Indian material — business chambers, party-linked unions and caste associations after Kothari — and close on the skew of access as the central sociological problem.
