US Government and Politics Unit 4: American political ideologies and beliefs

Americans form political beliefs through socialization, which polls measure and ideologies organize into views on government's role.

Covers: Political socialization, core values, public opinion polling, liberal, conservative and libertarian ideologies, ideology and policy

Study guide

Americans share core values such as individualism, equality of opportunity, free enterprise, the rule of law and limited government, though they disagree about how to apply them. Political socialization is the process of forming political beliefs. Family has the strongest influence, and schools, peers, media, religion and major events also matter. Generational effects come from shared experiences (like growing up during a war), and life-cycle effects come from changing needs with age. Globalization has also shaped views on trade and immigration.

Public opinion is measured through polls. Scientific polls use random samples that represent the population, keep the margin of sampling error small, and ask neutral questions; biased wording, poor samples and nonresponse reduce accuracy. Types include opinion polls, tracking polls, benchmark polls and exit polls. Polls influence campaigns and policymakers, but critics worry about bandwagon effects.

Ideologies organize beliefs about government's role. Liberals generally favor more government involvement in the economy and social programs but less regulation of personal behavior. Conservatives generally favor less government in the economy, lower taxes and a stronger emphasis on traditional values and law and order. Libertarians favor minimal government in both economic and personal matters. These views shape positions on economic policy (Keynesian versus supply-side approaches), social policy and the role of the Federal Reserve. The Democratic Party leans liberal and the Republican Party leans conservative, though both contain a range of views.

In *The Wealth of Nations* (1776), Adam Smith argued that free markets, guided by individuals pursuing their own interests (the 'invisible hand'), produce more wealth than government control. His ideas underlie laissez-faire and free-enterprise arguments for limiting government's role in the economy. Fiscal policy is Congress and the president changing taxes and spending. Monetary policy is the Federal Reserve adjusting interest rates and the money supply to control inflation and unemployment. Keynesians favor government spending to boost demand in downturns, while supply-side economists favor tax cuts and deregulation to encourage investment.

Over recent decades, Americans have sorted more consistently into parties by ideology. Conservatives have become more Republican and liberals more Democratic, and more voters pick the same party for every office (straight-ticket voting) instead of splitting their tickets. Political efficacy is a citizen's belief that they can understand politics (internal efficacy) and that government will respond to people like them (external efficacy). People with higher efficacy are more likely to vote and participate.

Key ideas

• Family is the strongest agent of political socialization.
• Scientific polls rely on random samples and neutral wording.
• Liberals favor more economic intervention; conservatives favor less.
• Libertarians want minimal government in all areas.
• Ideology shapes views on economic and social policy.

Formulas and rules

Common mistakes

• Thinking a bigger sample always fixes bias; a biased sample stays biased.
• Treating ideology and party as identical; they overlap but differ.
