The Concept of Power (Leaving Cert Politics and Society): Revision Notes
The Concept of Power
Understanding power is fundamental to analysing decision-making in schools and wider society. Power operates in multiple ways, from obvious enforcement to subtle influence that shapes what we consider normal.

What is power?
Power refers to the capacity to influence or control other people's behaviour, decisions, or beliefs. This influence can work through different methods, creating what scholars call dimensions of power.
Power manifests in three distinct ways:
- Visible power: Direct enforcement that compels compliance
- Hidden power: Behind-the-scenes control over what gets decided
- Invisible power: Subtle influence that shapes people's understanding of what is "normal"
Lukes' dimensions of power framework
Political theorist Steven Lukes identified three key dimensions of power, with a fourth dimension added to the syllabus. Each dimension operates differently and has varying levels of effectiveness.
First dimension: Decision-making power (visible)
This dimension involves getting people to act through direct authority. Those in power use their position to enforce rules, with clear consequences for non-compliance.
School Example: Direct Authority in Action
Principals assign detention to students who break rules. Students attend these detentions even when they would prefer not to, demonstrating how authority compels behaviour through visible consequences.
Society Example: Legal Enforcement
An Garda Síochána issues speeding fines to drivers who exceed limits. Governments collect taxes from citizens. Both examples show direct enforcement of rules with immediate penalties for non-compliance.
Second dimension: Agenda-setting power (hidden)
This more subtle form involves setting rules and practices that benefit certain groups. Power holders control which issues receive attention and which are excluded from discussion, structuring who wins and loses in decision-making processes.
School Example: Behind-the-Scenes Control
Uniform policies requiring branded items create financial benefits for specific suppliers whilst adding costs for families. The school's agenda-setting power determines these purchasing requirements without consulting affected families.
Society Example: Structural Advantages
Tax systems offer incentives to large corporations whilst providing limited relief for low-paid workers. Tenancy laws often favour landlords over tenants. These examples demonstrate how agenda-setting structures economic relationships.
Karl Marx's perspective on agenda-setting power emphasises how ruling groups shape institutions to protect their material interests. What society considers a "priority" often reflects class power rather than genuine need. Examination systems, for instance, may preserve advantages for those with greater resources whilst appearing neutral.
Third dimension: Ideological power (invisible)
This represents the most subtle form of power, making particular arrangements appear to be common sense. Rather than forcing compliance, ideological power shapes beliefs so people accept existing structures as natural or inevitable.
School Example: Unquestioned Beliefs
The belief that "exams are the only fair measure of ability" often goes unchallenged. This ideological acceptance prevents discussion of alternative assessment methods, maintaining the status quo without visible coercion.
Society Example: Shaping Public Understanding
Advertising campaigns link specific brands with social status. Political discourse frames certain budget cuts as "inevitable" rather than policy choices. These examples show how ideological power shapes public understanding.
Noam Chomsky's analysis of ideological power focuses on how media and elite institutions manufacture consent. By setting narratives and frames, these institutions guide what the public sees as normal or acceptable. Headlines, soundbites, and platform algorithms steer which issues appear urgent whilst making others invisible.
Fourth dimension: Power of the 'powerless'
This dimension recognises that people without formal authority can still influence norms, rules, and agendas through collective action and social pressure.
School Example: Student-Led Change
Student councils successfully campaign for healthier canteen options. Peer groups establish trends in language and fashion that influence school culture without formal authority.
Society Example: Grassroots Influence
Youth climate strikes elevated environmental issues on political agendas. Community campaigns change local planning decisions. These examples demonstrate bottom-up pressure that can challenge established power structures.
Analysing power effectiveness
Understanding Power Impact
Different dimensions of power vary in their speed and depth of impact:
- Decision-making power produces fast results but has narrow effects that may create resistance
- Agenda-setting power creates deeper change by structuring choices and excluding alternatives from consideration
- Ideological power often proves strongest because people comply voluntarily, believing arrangements are natural rather than imposed
- Power of the powerless reminds us that democracy depends on bottom-up pressure that can reopen agendas and challenge dominant ideologies
The most effective power combines agenda-setting with ideological control, creating systems that appear natural whilst serving particular interests. However, organised collective action can disrupt these arrangements by challenging both what gets decided and what seems normal.
Key theorists and their contributions
Karl Marx emphasised how dominant groups shape institutions to protect their material interests. Class power determines what society treats as priorities, with economic relationships structuring political agendas.
Noam Chomsky analysed how media and elite institutions manufacture public consent through narrative control. By setting frames and limiting discussion parameters, these institutions guide public opinion whilst maintaining apparent neutrality.
Exam guidance
Essential Exam Strategy
When answering questions about power:
- Label examples with specific Lukes dimensions (decision-making, agenda-setting, ideological, or powerless)
- Provide both school and society examples for each dimension
- Reference Marx when discussing agenda-setting and structural power
- Reference Chomsky when analysing ideological power and media influence
- Use key terms: decision-making, agenda-setting, ideology, consent, framing
- For evaluation questions, argue that ideological and agenda-setting powers are typically most effective, then demonstrate how bottom-up action can challenge them
Key Points to Remember:
-
Power = the ability to influence behaviour, rules, and beliefs
-
Lukes' framework: 1) decision-making, 2) agenda-setting, 3) ideological power, plus 4) power of the 'powerless'
-
Marx: dominant interests shape agendas and institutions to protect material advantages
-
Chomsky: media and elite framing manufactures consent through ideological power
-
Subtle power (agenda-setting + ideological) proves most effective until challenged by organised, bottom-up action
