What is a political ideology?
A political ideology is a connected set of beliefs that (1) describes how society is now, (2) says how it should be, and (3) suggests how to get there. Each ideology gives its own answer to a few big questions:
- Human nature – are people mainly selfish, cooperative, or shaped by society?
- The state – how big and how strong should government be?
- Society – is it a set of individuals, or a community with shared bonds?
- The economy – free markets or public ownership and planning?
The word was coined in France around 1796. Some thinkers (like Karl Marx) used it in a negative sense: ideas that hide who holds power.
Political socialisation: where our views come from
Political socialisation is the lifelong process by which we learn political values. Main agents:
- Family – the strongest early influence.
- School – civics, rituals, debates.
- Peers and religion.
- Media and social media – what news we see shapes what we think matters.
- Events – a war, a recession or a pandemic can shift a whole generation (a generational effect). Views can also change with age and life-cycle (job, children, taxes).
Left, right and the political spectrum
In the French National Assembly of 1789, supporters of revolution sat to the left of the chair and supporters of the king to the right. Since then, left usually means stress on equality and change, and right on tradition, order and markets.
Views on change can also be named: reactionary (go back), conservative (keep, change slowly), reformist (improve step by step), revolutionary (change everything quickly). Ideas from the Enlightenment – reason, rights, equality – fed the 19th-century rise of liberalism, socialism and nationalism.
Core ideologies: liberalism, conservatism, socialism
Liberalism
The individual comes first: freedom of speech and religion, rights, rule of law, government by consent, toleration. Classical liberals (John Locke, Adam Smith) want a small state; modern liberals (J. S. Mill, later welfare liberals) accept a bigger state to give everyone a fair chance (education, health).
Conservatism
Value tradition, order, family, property and gradual change; doubt grand plans built only on theory. Edmund Burke said society is a partnership between the dead, the living and the unborn. The New Right later mixed free markets with strong traditional values.
Socialism
Stress equality, cooperation and common good; criticise capitalism for inequality. Ranges from revolutionary communism (Marx: workers take over all property) to social democracy (markets plus welfare state, public services, workers' rights).
Other ideologies
- Feminism – equality of women and men; the personal is political; liberal, socialist and radical strands.
- Ecologism – humans are part of nature; growth has limits; protect future generations.
- Anarchism – the state is harmful and unnecessary; society can run by voluntary cooperation.
- Multiculturalism – recognise and respect cultural diversity within one state.
- Nationalism – the nation should rule itself; can be liberal or exclusive.
Many ideologies also imagine utopias – ideal societies (from Thomas More's Utopia to socialist communes), which inspire reform but can turn harsh when forced on people.
Two axes are better than one line
A single left–right line mixes two different questions. A two-axis model separates them: economic (equality and public ownership ↔ free market) and social (personal freedom ↔ authority and tradition). Since the 1990s many people have also described a crisis of ideologies and the rise of populism, which divides society into “the pure people” and “the corrupt elite” and can join with left or right ideas.
Ideology, parties and policy
Parties turn ideologies into programmes (manifestos). Ideology shapes:
- Economic policy – taxes, spending, regulation, minimum wage, privatisation.
- Social policy – education, health, marriage, drugs, immigration, speech.
In most countries parties are broad coalitions, so a real party may combine ideas from several ideologies.
Measuring public opinion
Public opinion is measured with polls (surveys). A good poll uses a random sample large enough (often about 1,000 people gives a margin of error near ±3 percentage points), neutral question wording, and is open about who paid for it. Watch out for leading questions, tiny or self-selected samples (online votes) and polls far from the event.
Exam tips
Learn each ideology's view on human nature, state, society and economy, plus one key thinker. Compare two ideologies on one issue. In data questions, check sample size, margin of error and question wording before drawing a conclusion.
Try it at home
Ask three family members: “Should the government provide free bus travel for everyone?” Note their answer and their reason. Is the reason about equality, freedom, tradition or the environment? Place each answer on the two-axis board in step 6.
Key formulas and definitions
- Ideology = view of how society is + how it should be + how to get there
- Agents of socialisation: family, school, peers, religion, media, events
- Left (1789) = change and equality · Right = tradition, order, markets
- Liberalism: individual + rights · Conservatism: tradition + order · Socialism: equality + common good
- Two axes: economic (equality ↔ market) × social (freedom ↔ authority)
- Good poll = random sample + enough people + neutral wording + margin of error
Worked examples
1. Which ideology best fits: “Cut taxes, keep government small, protect free speech and property.”?
Classical liberalism (on economics it overlaps with the New Right). Small state + individual rights + market economy.
2. A party wants free healthcare, higher taxes on the rich and stronger trade unions. Where does it sit on the economic axis?
Left side (equality/public provision). This is typical of social democracy, a moderate form of socialism.
3. A poll of 50 people who answered an online vote says 80% want a new law. Should we trust it?
Not much. The sample is tiny and self-selected (only interested people vote), so it is not random. With 50 people the margin of error would be roughly ±14 points even if random.
4. Compare how a conservative and an ecologist might view a plan to build a big highway through an old forest.
A conservative may worry about losing a traditional landscape but may also value economic growth and property rights; an ecologist will stress limits to growth, biodiversity and future generations and will likely oppose it. Both may resist rapid change, but for different reasons.
Common mistakes
- Thinking left and right are fixed forever. Their meaning has shifted over time and differs between countries.
- Treating every ideology as one single idea. Each has strands (classical vs modern liberalism, revolutionary vs democratic socialism).
- Confusing a party with an ideology. Real parties often mix several ideologies.
- Trusting any poll result. Always check sample size, sampling method and question wording.
