We often encounter questions about our opinions, whether it’s about predicting the Super Bowl winner, deciding who wore it best on the red carpet, or choosing a candidate in an election. Public opinion polls are a common way to gather these opinions. In American politics, decision-makers have long used these polls to guide elections and important legislation. However, tracking public opinion accurately can be challenging, and sometimes the results are misleading.
In 1948, the Chicago Daily Tribune made a famous error with the headline “Dewey Defeats Truman,” even though Dewey did not win. This mistake happened because the newspaper relied on inaccurate polls. Such errors are not uncommon, raising the question: why do inaccuracies occur, and why do we still use polls?
A key concept in polling is the sample, which is the group of people who respond to the poll. The accuracy of a poll largely depends on its sample, which can be flawed in several ways. A sample might be too small, too narrow, or the poll questions might be too complex.
Small samples are problematic because they don’t represent the entire population. While it’s impractical to ask everyone in a country for their opinion, larger samples generally provide more accurate predictions.
Narrow samples, which only include a specific type of person, can also lead to misleading results. For example, if you ask people in Idaho whether the potato is the best vegetable, you’ll likely get a different answer than if you asked people in New Mexico, where beans are more popular. A diverse sample should include various ages, races, genders, and geographic regions.
Polls that are too complex can produce unhelpful results. If people are asked about topics they know little about, their answers might be as random as consulting a Magic 8 ball.
Bias can also come from the person conducting the poll, known as interviewer bias. People often give socially acceptable answers to avoid confrontation or appearing insensitive, rather than sharing their true opinions.
The wording of questions is crucial. Some polls, called push polls, are designed to influence responses. For example, “Would you vote for candidate Smith?” is straightforward, while “Would you vote for candidate Smith if you knew he had committed unethical acts?” is a push poll.
Despite their limitations, public opinion polls are still widely used. They offer insights into the thoughts and feelings of large groups of people. Politicians use them to gauge support for legislation, and media outlets use them to identify trending celebrities. Polls also give people a sense that their opinions are being heard.
Next time you encounter a poll, whether it’s a phone call or an online survey, think about who is asking and why. Approach the poll and its results with a critical mindset, considering the potential biases and limitations involved.
Design and conduct a simple public opinion poll among your classmates on a topic of your choice. Ensure you consider sample size, diversity, and question wording. Analyze the results and discuss any potential biases or inaccuracies that might have affected the outcome.
Research the 1948 “Dewey Defeats Truman” headline. Create a presentation explaining what went wrong with the polling methods used at the time. Discuss how modern polling techniques have evolved to prevent similar mistakes.
Participate in a simulation where you draw different sample sizes from a larger “population” of data. Compare the accuracy of the results from small versus large samples. Reflect on how sample size impacts the reliability of poll results.
Examine a series of poll questions and identify potential biases in wording or delivery. Rewrite the questions to eliminate bias and discuss how these changes might affect the responses received.
Engage in a classroom debate on the pros and cons of public opinion polls. Use examples from history and current events to support your arguments. Consider the impact of polls on politics, media, and public perception.

We are often asked for our opinions. Which team do you think will win the Super Bowl? Who wore it better on the red carpet? Who are you going to vote for in the mayoral election? Public opinion polls are everywhere. Important decision-makers in American government have long relied on public opinion polls during elections and significant legislation. The challenge is that public opinion isn’t easy to track and, at times, may not be accurate.
In 1948, the Chicago Daily Tribune ran a now-famous headline: “Dewey Defeats Truman,” displayed in large, bold letters. The issue was that Dewey hadn’t defeated Truman. The Tribune had relied on polls to reach that conclusion. This kind of error occurs frequently because public opinion polls can be inaccurate or misleading. So, why do these inaccuracies happen, and why do we continue to use them?
First, let’s define an important term: sample. A sample is the group of people that respond to questions during a public opinion poll. The quality of a poll largely depends on its sample, which can be flawed in several key ways. It can be too small, too narrow, or the poll itself can be overly complex. Polls that are too small are problematic for obvious reasons. While it’s impossible to ask every single person in America for their opinion, a larger sample generally leads to more accurate predictions.
Polls that are too narrow, which only ask a specific type of person a question, can also be misleading. For example, if you conducted a poll about whether the potato is the best vegetable in America and only asked people in Idaho, where the state food is the potato, you would likely receive a different answer than if you asked people in New Mexico, where the state vegetable is beans. Ensuring diversity in your sample means including a range of ages, races, genders, and geographic regions, among other factors.
Additionally, polls that are too complex can yield unhelpful results. If you’re asking people for their opinions on topics they know little about, the results will be meaningless. In such cases, you might as well consult a Magic 8 ball.
It’s not just the respondents that can introduce bias; the person conducting the poll can also influence the results. This is known as interviewer bias. Humans generally avoid confrontation and may worry that their answers could reflect poorly on them. As a result, people often provide socially acceptable responses rather than their true opinions, as they may not want to appear insensitive or prejudiced.
The wording of questions is also crucial. When polls are designed to sway responses in a particular direction, they are referred to as push polls. For instance, “Would you vote for candidate Smith?” is a straightforward question, while “Would you vote for candidate Smith if you knew he had committed unethical acts?” is a push poll.
Despite their limitations, public opinion polls remain prevalent. They offer a glimpse into the thoughts and moods of large groups of people. They provide politicians with insights into legislation that they believe a majority of Americans will support. They also help media outlets determine which celebrities are trending in fashion. Finally, they give those polled a sense that their voices are being heard.
So, the next time you receive a call asking for your opinion or come across a poll online, take a moment to consider who is asking and why. Then, approach that poll and its results with a critical mindset.
