Key TermsKey Terms

• public affairs: events and issues that concern the people at large, such as politics and the making of public policies

• public opinion: those attitudes held by a significant number of people on matters of government and politics

• mass media: those means of communication that reach large, widely dispersed audiences simultaneously


Key Terms, cont.Key Terms, cont.

• peer group: those people with whom one regularly associates, including friends, classmates, co-workers, and neighbors

• opinion leader: any person who has an unusually strong influence on the views of others


IntroductionIntroduction

• What is public opinion, and what factors help to shape it?

– Public opinion consists of the attitudes held by a significant number of people about public affairs—matters of government and politics.

– It is shaped by a wide variety of factors, such as family, school, race, occupation, gender, mass media, peer groups, opinion leaders, and historic events.


Different PublicsDifferent Publics

• Public opinion in the United States is typically divided.

• Any given public issue is likely to have separate groups with their own points of view.

• In addition, people disagree about which public issues are important.

• Few issues capture the attention of all Americans.

• Most issues are of little interest to the majority.


Public AffairsPublic Affairs

• Checkpoint: What do public affairs include?

– Public affairs include events and issues involving politics, public issues, and the making of public policies.

– Examples include political parties, candidates, taxes, unemployment, national defense, foreign policy, and so forth.

– Technically, public opinion includes only those views that relate to public affairs.


Public OpinionPublic Opinion

• Public opinion consists of those attitudes publicly expressed by a large number of people about matters of government and politics.– How might the

responses shown on this 2008 chart about the most important public issues change in 2012?


Political SocializationPolitical Socialization

• Public opinion is shaped by many different factors throughout our lives.

• The process by which a person gains his or her political views is called political socialization.

• This process begins in early childhood and involves the influence of many experiences and relationships. Two of these are family and school.


• Parents have a strong influence on the basic beliefs that will shape the political views of their children.

• Children tend to favor the political parties supported in the households in which they were raised.

Family InfluencesFamily Influences


• Schools try to prepare students to become good citizens by educating them about our political system.

• Schools also give students an informal education about decision-making, influence, and compromise.

School InfluenceSchool Influence


Other FactorsOther Factors

• In general, occupation and racial background are usually more significant than factors such as gender or place of residence.

• However, the nature of the issue can change what factors influence people’s views on it.

• Four other key factors that influence public opinion are the mass media, peer groups, opinion leaders, and historic events.


• The mass media includes radio, television, magazines, and newspapers.

• More than 98 percent of the 115 million U.S. households have a television, and most are turned on for eight or more hours a day.

Peer GroupsPeer Groups

• Checkpoint: How does one’s peer group shape his or her attitudes?

– Belonging to a peer group tends to reinforce what a person has already come to believe.

– This happens in part because peer group members share many socializing experiences and tend to be reluctant to disagree openly with others in their peer group.


Opinion LeaderOpinion Leader

• Some people listen to and draw ideas from opinion leaders.

• Many opinion leaders hold public office, while others are journalists or prominent members of society. – What is the cartoonist

implying about the media?


• Historic events can shape public opinion and policy.

• In the 1930s, the Great Depression wrecked the U.S. economy, shifting popular support to Democrats and persuading many Americans to support an increased role for the national government in U.S. economic and social life.

The Great DepressionThe Great Depression


The 1960s and 1970sThe 1960s and 1970s

• In the 1960s, the nation was shaken and divided by the civil rights movement, the Vietnam War, and the assassinations of President Kennedy and Martin Luther King, Jr.

• The 1970s saw the Watergate scandal and the resignation of President Nixon.

• The events of these two decades caused many American to lose respect and trust of their government.


ReviewReview

• Now that you have learned about what public opinion is and what factors shape it, go back and answer the Chapter Essential Question.– What is the place of the media and public

opinion in a democracy?


Section 2



1. Describe the challenges involved in measuring public opinion.

2. Explain why scientific opinion polls are the best way to measure public opinion.

3. Identify the five steps in the polling process.

4. Understand the problems in evaluating polls.

5. Recognize the limits on the impact of public opinion in a democracy.


Key TermsKey Terms

• mandate: the instructions a constituency gives its elected officials

• interest group: a private group that works to shape the making of public policy

• public opinion poll: a tool used to collect information by asking people questions

• straw vote: a nonscientific poll that asks many people the same question


Key Terms, cont.Key Terms, cont.

• universe: the whole population that a poll aims to measure

• sample: a representative slice of the total universe

• random sample: a polling group of randomly selected people

• quota sample: a polling group constructed to reflect the major characteristics of a given universe



• How is public opinion measured and used?

– Public opinion is measured by election results, personal contacts, media reporting, and especially by polls.

– The most common polls are straw polls, while the most accurate measures of public opinion are scientific polls.

– Officials use public opinion to guide their public policy decisions.


Measuring Public OpinionMeasuring Public Opinion

• Election results reflect public opinion to some degree, but often express voters’ views only on a few broad issues.

• The people also express their opinions in e-mails, letters, phone calls, or public meetings.

• The media both mirrors and helps shape public opinion.

• Interest groups share the views of their members in hopes of influencing policy.


Measuring Public Opinion, cont.Measuring Public Opinion, cont.

• Public officials get feedback on public opinion from their many contacts with the public, in the form of mail, phone calls, public meetings, and personal visits with constituents.


Public Opinion PollPublic Opinion Poll

• Public opinion is best measured by polls that ask people questions, but scientific polling techniques are needed to get accurate results.– What do you think the

cartoonist is saying about pollsters here?


Straw PollsStraw Polls

• Straw polls try to measure public opinion by asking many people the same questions, often by phone, email, or mail.

• This method is very unreliable, as there is no guarantee that the people who respond represent an accurate cross-section of the population.

• For example, a straw poll during the Great Depression picked the wrong presidential winner because it overlooked the large number of poor people who voted.


Scientific PollsScientific Polls

• Scientific polls are more accurate.

• There are hundreds of polling organizations in the U.S. today. Gallup and Pew are two of the best known.

• Scientific polls have five basic steps:

– Define the universe to be surveyed– Construct a sample– Prepare valid questions– Select and control how the poll is taken– Analyze and report the results


Universe and SampleUniverse and Sample

• The universe is the group whose opinions the poll tries to discover.

• For large groups, pollsters create a sample, or representative slice.

• A random sample is made of randomly selected people. Most national polls use random samples of 1,500 people to represent the U.S. population.

• The law of probability says that a proper random sample can be quite accurate.


Samples, cont.Samples, cont.

• A typical margin of error in a scientific poll is plus or minus 3 percent.

• A quota sample is less complicated but less accurate.

• Pollsters try to create a quota sample so that it reflects the major characteristics of a given universe, such as race or gender.

• People often belong to more than one category, making it hard to create an accurate sample.


• How pollsters interact with people can affect poll accuracy.

• Most polls today are telephone surveys.

• Pollsters use computers to analyze and publish polling data.

Interviewing and AnalyzingInterviewing and Analyzing


Evaluating PollsEvaluating Polls

• When evaluating the intent of a poll, ask yourself the following questions:

– Who is responsible for the poll? Polls sponsored by political campaigns may try to mislead voters.

– Why is the poll being conducted? Polls meant to boost a candidate’s approval ratings are not reliable.


Evaluating Polls, cont.Evaluating Polls, cont.

• When evaluating a poll’s methods, ask yourself the following questions:

– What is the poll’s universe? Ask if the sample is truly representative.

– How was the sample chosen? Samples should be selected randomly.

– How were questions written and asked? Leading questions can alter results.

– When was the data collected? Opinions change quickly during elections.


Evaluating Polls, cont.Evaluating Polls, cont.

• Checkpoint: What is difficult for polls to measure?

– Scientific polls are fairly accurate, but have difficulty measuring the intensity, stability, and relevance of opinions.

• Intensity: how strongly someone holds an opinion.• Stability: how likely an opinion is to change.• Relevance: how important an opinion is to the

person who holds it.


Limits on PollsLimits on Polls

• Democracy is more than measuring public opinion, and polls are not substitutes for elections.

• Minority interests must be protected against the excesses of majority views and actions.

• Polls are best at focusing attention on public questions and stimulating discussion of them.
