Double-Barreled Question
Accurate data collection is essential for making informed decisions in research, business, and policy. However, poorly constructed survey questions can introduce bias, confusion, and unreliable responses, leading to misleading conclusions. One of the most common errors in survey design is the double-barreled question, which asks about two or more topics at once and forces respondents to provide a single answer.
When survey questions are unclear or ask about multiple things at once, respondents may:
- Feel forced to choose one aspect to address, making it unclear which part of the question influenced their response.
- Choose a neutral or average answer, even if they have different opinions about each issue mentioned.
- Skip the question altogether, leading to incomplete data.
By recognizing and avoiding double-barreled questions, researchers can collect more reliable and actionable insights from their surveys.
What is a Double-Barreled Question?

A double-barreled question is a survey or interview question that asks about two or more issues within a single question, yet only allows for one response. This can lead to confusing or inaccurate answers, as respondents may have different opinions on each part of the question but are unable to express them separately.
Why Do Double-Barreled Questions Happen?
Many double-barreled questions arise due to poor wording or oversight during survey creation. They often appear when researchers attempt to streamline surveys by combining related topics, but in doing so, they reduce clarity and reliability in responses.
For example, consider the following question:
“How satisfied are you with our customer support and refund policy?”
This question assumes that customer support and the refund policy are equally important and related. However, a customer may be happy with customer support but frustrated with the refund policy. When faced with such a question, respondents might:
- Answer only one part of the question, leading to misleading results.
- Select a neutral response, even if they have contrasting opinions on each issue.
- Skip the question entirely, reducing response quality.
To ensure meaningful insights, each aspect of a survey question should focus on one specific issue at a time.
Examples of Double-Barreled Questions
Double-barreled questions are problematic in surveys because they introduce ambiguity and force respondents to provide a single answer to multiple questions. This can lead to unreliable data, making it difficult to interpret what aspect of the question influenced the response. Below are several examples of double-barreled questions, along with explanations of why they are problematic and how they can lead to inaccurate results.
1. “How satisfied are you with your job and salary?”
At first glance, this question seems straightforward. However, it combines two different aspects—job satisfaction and salary satisfaction. A person might love their job but feel underpaid or be satisfied with their salary but dislike their role or work environment.
Since respondents are only allowed one answer, they might feel conflicted, leading them to either:
- Pick a neutral option, even though their feelings about each aspect differ.
- The answer is based on one aspect, making the data unreliable.
For example, if most people answer “dissatisfied”, it remains unclear whether they are dissatisfied with their job duties, salary, or both. This kind of unclear data makes decision-making difficult, especially when employers use surveys to improve employee retention.
2. “Do you agree that our website is user-friendly and has a great design?”
This question assumes that user-friendliness and design quality are the same thing when, in reality, they are two separate aspects of a website. A website might be visually appealing but difficult to navigate, or highly functional but lacking a modern design.
By grouping these two factors, the survey:
- Forces users to evaluate two aspects simultaneously, making it unclear which one they are responding to.
- Fails to provide actionable insights—if users say “no,” does that mean they dislike the usability, the design, or both?
If a company is trying to improve both functionality and aesthetics, this question does not provide useful insights to guide its strategy.
3. “Was your experience with our online ordering process and customer service satisfactory?”
The ordering process and customer service experience are two distinct stages in a customer’s journey. A customer may find the ordering process easy but have a frustrating experience with support when resolving an issue.
By combining both aspects into one question, the business loses the ability to:
- Identify specific areas for improvement.
- Understand if negative feedback is due to checkout issues or poor customer support.
If survey respondents mark this question as “dissatisfied,” the company will not know which aspect needs improvement.
4. “Do you support government policies on education and healthcare?”
Education and healthcare are separate policy areas, and people often have different views on each. Someone might support education funding but disagree with healthcare policies.
By combining them into one question, respondents are forced to either agree or disagree with both, which:
- Misrepresents public opinion because it does not allow for nuanced responses.
- This leads to unreliable data, making it difficult for policymakers to understand public priorities.
This question would be especially problematic in a political survey, where policymakers need to make informed decisions based on public sentiment.
5. “How would you rate our hotel’s cleanliness and breakfast options?”
While both cleanliness and food quality contribute to the hotel experience, they are two completely different factors. A guest may find the hotel spotless but dislike the breakfast or love the breakfast but feel the rooms were not properly cleaned.
By forcing respondents to evaluate both in one response, the hotel management:
- Fails to collect clear feedback on either aspect.
- Misses opportunities for targeted improvements.
For example, if guests answer “very satisfied”, does that mean they enjoyed both cleanliness and breakfast or just one of them? Without clarity, the hotel cannot make data-driven improvements to guest experiences.
How to Avoid Double-Barreled Questions
Avoiding double-barreled questions is essential for obtaining clear, reliable, and actionable survey data. The key is to focus each question on a single issue and ensure clarity in wording. Below are strategies to prevent double-barreled questions, with examples of how to rewrite problematic questions.
1. Break Questions into Separate Parts
One of the most effective ways to fix a double-barreled question is by splitting it into two. This allows respondents to answer each aspect individually, giving researchers a more precise understanding of their opinions.
Example Fix:
❌”How satisfied are you with your job and salary?”
After:
✅“How satisfied are you with your job?”
✅“How satisfied are you with your salary?”
By separating these into two distinct questions, employers can pinpoint whether job dissatisfaction is related to salary, work culture, job responsibilities, or other factors.
2. Be Specific and Avoid Assumptions
Questions that assume a particular opinion or group different topics together can be restructured to focus on just one element.
Example Fix:
❌“Do you agree that our great design website is user-friendly?”
After:
✅“How would you rate the user-friendliness of our website?”
This revision allows users to evaluate usability and design separately, ensuring that improvements are made in the right area.
3. Test Survey Questions Before Launching
Before sending out a survey, conducting a pilot test with a small group of participants can help identify unclear or misleading questions. Survey testers can provide feedback on whether questions are easy to understand and answer accurately.
For example, if testers express confusion over a question like:
❌“Was your experience with our online ordering process and customer service satisfactory?”
It can be revised to:
✅“How satisfied are you with our online ordering process?”
✅“How satisfied are you with our customer service?”
This ensures that each response is precise and actionable.
4. Use Clear and Neutral Wording
Sometimes, double-barreled questions also include biased wording, which influences responses. Ensuring that questions remain neutral and well-structured helps eliminate confusion and improve data accuracy.
Example Fix:
❌“Do you support government policies on education and healthcare?”
After:
✅“Do you support current government policies on education?”
✅“Do you support current government policies on healthcare?”
This ensures that each topic is addressed separately, providing meaningful insights into public opinion.
5. Keep Surveys Simple and Focused
Overcomplicating survey questions by trying to collect too much information at once can lead to confusion. Keeping each question concise and focused on a single topic ensures that respondents provide clear and relevant answers.
Example Fix:
❌”How would you rate our hotel’s cleanliness and breakfast options?”
After:
✅“How satisfied were you with the cleanliness of the hotel?”
✅“How satisfied were you with the breakfast quality?”
This revision allows the hotel to identify which areas need improvement instead of guessing whether the problem is cleanliness or food quality.
Best Practices to Increase Response Rates for Your Surveys
Collecting accurate and meaningful survey data requires not only well-structured questions but also a high response rate. A survey with a low response rate can lead to biased results, as only a small, potentially unrepresentative group of respondents may provide answers. This can distort insights and reduce the reliability of the findings.
Increasing survey response rates requires careful question design, strategic distribution, and engaging formats that encourage participants to complete the survey. Below are key best practices that can significantly improve response rates and the quality of the data collected.
Keep Questions Simple and Direct
Survey respondents are more likely to complete a survey when the questions are clear, concise, and easy to understand. When questions are overly complex, long, or ambiguous, participants may feel frustrated or confused, leading to dropouts or inaccurate answers.
A well-designed question should focus on a single topic, avoid technical jargon, and be as straightforward as possible. Instead of using vague or multi-layered wording, researchers should break down questions into simpler, more digestible parts to maintain clarity.
For example:
❌”How do you feel about our new product line, including packaging, pricing, and usability?”
✅ “How would you rate the usability of our new product?” (Separate questions can address packaging and pricing.)
When respondents can quickly understand and answer questions, they are more likely to complete the survey and provide useful insights.
Make Surveys Short and Engaging
The length of a survey has a direct impact on completion rates. People are less likely to complete long surveys, especially if they seem tedious or repetitive. Research shows that shorter surveys (5–10 minutes) tend to have significantly higher completion rates than those that take 15 minutes or more.
To keep respondents engaged:
- Limit surveys to essential questions that align with research objectives.
- Use progress indicators to show how much of the survey is left.
- Use interactive elements, such as multiple-choice options and sliders, to make responses feel effortless.
If a survey must be longer, consider offering an incentive to encourage respondents to complete it.
Offer Incentives for Participation
Providing an incentive can significantly boost response rates, as it gives participants a reason to complete the survey. Incentives can take many forms, including discounts, gift cards, sweepstakes entries, or access to exclusive content.
However, incentives should be aligned with the target audience. For example, an e-commerce store could offer a 10% discount, while a B2B company might offer a downloadable industry report. The key is to ensure that the incentive is appealing enough to motivate participation without introducing bias in responses (e.g., respondents rushing through just to claim a reward).
Send Surveys at the Right Time
Timing is critical in determining whether respondents will take the time to complete a survey. Sending a survey immediately after a customer interaction—such as a purchase or customer support call—can result in higher engagement and more accurate feedback.
For workplace or employee satisfaction surveys, sending them during low-stress periods (e.g., avoiding the busiest workdays) can improve participation. Testing different send times and tracking response rates can help researchers determine the best timing for their audience.
Optimize for Mobile Devices
With a growing number of users accessing emails and websites on their smartphones, ensuring that surveys are mobile-friendly is essential. If a survey is difficult to complete on a phone due to small fonts, excessive scrolling, or unresponsive design, respondents may abandon it before finishing.
Best practices for mobile-friendly surveys include:
- Using a responsive design that adapts to different screen sizes.
- Minimizing the number of open-ended questions (typing on mobile is harder).
- Ensuring that answer options are easy to select without excessive scrolling.
By optimizing surveys for mobile users, businesses can reach a wider audience and improve response rates across different demographics.
Other Types of Survey Question Errors
In addition to double-barreled questions, many other common errors in survey design can introduce bias, confusion, or misleading data. Poorly worded survey questions can skew responses, reduce accuracy, and limit the usefulness of insights. Below are several common survey question mistakes, along with examples of how they can impact data collection.
Leading Questions
A leading question suggests a particular answer, often by using biased wording that influences the respondent’s choice. These questions can subtly push respondents toward a preferred response, distorting survey results.
For example:
- Before: “How much did you enjoy our excellent customer service?”
- After: “How would you rate your experience with our customer service?”
The first version assumes that the customer service was excellent, which may not reflect the respondent’s actual experience. A neutral phrasing ensures that answers are unbiased and accurate.
Ambiguous Questions
An ambiguous question lacks clarity or is too broad, making it open to multiple interpretations. Respondents may struggle to understand what is being asked, leading to inconsistent responses.
For example:
- Before: “How do you feel about your purchase?”
- After: “How satisfied are you with your purchase?” (with a scale from “Very Satisfied” to “Very Dissatisfied”).
The word “feel” in the first version is too vague—does it refer to satisfaction, regret, excitement, or frustration? Providing clear answer choices ensures that data is consistent and interpretable.
Double Negatives
A double-negative question contains two negative words that make the statement confusing and difficult to interpret. This can lead to misunderstood responses and inaccurate survey data.
For example:
- Before: “Do you oppose the government not investing in education?”
- After: “Do you support government investment in education?”
The first version forces respondents to process multiple negations, increasing the likelihood of errors in interpretation. Clear, positive phrasing eliminates confusion and improves data quality.
Complex Questions
A complex question includes too many details or conditions, making it difficult for respondents to answer accurately and efficiently.
For example:
- Before: “If you had to commute by bus, train, bicycle, car, or on foot, which would you choose, considering weather, costs, and time constraints?”
- After:
- “Which method of transportation do you use most often?”
- “What factors influence your choice of transportation?”
Breaking a complex question into smaller, more manageable parts allows respondents to provide clearer answers without feeling overwhelmed.
Using Jargon or Technical Language
Survey questions should be easy to understand for all respondents. Using industry jargon or complex terminology can confuse participants, leading to misinterpretations and unreliable data.
For example:
- Before: “How satisfied are you with our SaaS platform’s omnichannel attribution modeling?”
- After: “How satisfied are you with how we track customer interactions across multiple channels?”
By replacing jargon with everyday language, researchers can ensure that all respondents understand the question clearly, improving the reliability of responses.
Question Order Bias
The sequence of questions in a survey can influence how respondents interpret and answer later questions. This is known as question order bias, and it can lead to biased responses if earlier questions frame expectations or assumptions.
For example:
- A survey asking, “Do you support increased spending on national security?”, followed by “Do you support cutting education funding?”, might influence respondents to prioritize national security over education, even if they had no prior strong opinion on the issue.
To avoid question-order bias, it’s best to start with neutral, broad questions before introducing more specific or opinion-based ones.
To Wrap Things Up
Avoiding survey question errors, such as double-barreled questions, leading questions, and ambiguity, is essential for gathering high-quality data. Well-structured questions help eliminate bias, improve response rates, and provide valuable insights that can lead to better decision-making. By using clear, direct, and focused survey questions, researchers can ensure accurate and actionable feedback.
