Double-barreled Questions and How to Avoid Them

What are double-barreled questions?

A double-barreled question, also known as a compound question, a double-ended question, or a double-direct question, is a question that touches upon two different issues However, it only allows for a single answer.

Essentially, a double-barreled question makes the mistake of combining what should be two questions into one.

Double-barreled questions are one of the most common but easily avoidable mistakes we see at PickFu. In this article, you’ll learn to recognize and avoid double-barreled questions.

An example of a double-barreled question in surveys

The following are examples of double-barreled questions:

How satisfied are you with your work environment and compensation?
In this example, a respondent could potentially be satisfied with her work environment but feel she is underpaid. Or, she may be satisfied with her paycheck, but hate her workplace. So how should she answer this question? And how should you interpret her answer? What did she truly intend to say?

Is this video clear and interesting?
In this example, clear and interesting are both positive attributes. However, the two attributes are not interchangeable. The video might be clear but dull at the same time. Or it might be interesting to watch but not make sense. So, should survey respondents say yes? Some might think so, others won’t, but almost assuredly, not everyone will answer this question in the same manner.

What’s the problem with double-barreled questions?

The problem with double-barreled questions is that they lead to confusion. Respondents are confused because they’ve been asked two questions, but aren’t sure which one to answer. Then, when it comes time to analyze the responses, survey creators are confused by the results. Because you can’t be sure which question the respondents answered, you also can’t be sure exactly what is being measured.

Sometimes survey creators ask a double-barreled question in order to make their surveys shorter. While this is well-intentioned, asking double-barreled questions returns inaccurate or unreliable results. This, in turn, makes the survey a waste of time and money. Worse, if you don’t realize the results are skewed, the survey could lead you to make unwise business decisions, such as changing something that didn’t need to be changed or focusing on an area that isn’t the most pressing problem.

How to avoid double-barreled questions

Double-barreled questions are one of the most common surveying mistakes, but also probably the easiest to fix. You correct a double-barreled question by separating the combined question into two distinct questions.

Double-barreled question:
How satisfied are you with your work environment and compensation?
Separated questions:
How satisfied are you with your work environment?
How satisfied are you with your compensation?

Double-barreled question:
Is the video clear and interesting?
Separated questions:
Is the video clear?
Is the video interesting?

A shorthand way to identify double-barreled question is carefully examining the use of the word and. Though this is not a fool-proof test (the use of and does not always indicate a double-barreled question), it is a good watchword to double-check yourself.

Additionally, another way to correct a double-barreled question is to ask follow-up questions. For example, if you ask, “Is the video clear?” and the respondent answers affirmatively, you could then follow up by asking whether it was also interesting.

Double-barreled questions on PickFu

Sometimes, in the interest of maximizing a poll’s value, a surveyor will inadvertently ask a double-barreled question. Usually, the person will try to test a title and a subtitle in a single poll, or a logo and a tagline in a single poll.

But because a title is distinct from a subtitle, it’s judged by different criteria. Each has different considerations. The same goes for a logo and tagline. Or, in the case below, a logo and a business name:

A comparison of a double barreled question where the question asked two questions, one inside of one another that will skew the results.

When a double-barreled question asks two separate things, respondents usually only respond to the one that means the most to them.

In the poll’s results, you can see the divide. Some respondents commented on both the name and the logo. Some respondents commented only on the name. Some only on the logo. But even in cases where the respondent only reacted to one element, the reaction was likely subconsciously influenced by the other: Those who commented on the name were influenced by their feelings about the logo, and those who commented on the logo were influenced by their feelings about the name. And in the end, how did everyone determine which to vote for — by which name was better, or by which logo was better?

You only want to test one thing at a time. So if you’re testing your business name, test your business name only. Leave the logo design, tagline, and any other considerations for later tests.

Double-barreled questions with authors

Authors often make the mistake of asking double-barreled questions by testing their book titles and subtitles together.

Double-barreled questions combine two questions that should be distinct. Here, subtitles and titles are muddled together. The question that's asked is "Which Book title is more appealing".

What’s the problem? Some people might like 101 Real Estate Tips You Wish You Knew (the title in Option A), but prefer “The Ultimate Collection of Tips, Tactics, and More for Getting a Great Deal” (the subtitle in Option B). So how should the reader judge the appeal?

To fix this double-barreled question, the author should test the two titles against each other, without a subtitle, i.e.:

Which book title is more appealing?
Option A: 101 Real Estate Tips You Wish You Knew
Option B: 101 Real Estate Tips for Buying a House

Then, once a title had been decided upon, the author could run a second test with the subtitle options paired with the winning title.

Let’s suppose that Option A won the first test. The second test would look like this:

Which subtitle is more appealing?
Option A: 101 Real Estate Tips You Wish You Knew: The Ultimate First-Time Homebuyer’s Collections of Tips, Tactics, and More to Get the Best Deal Possible
Option B: 101 Real Estate Tips You Wish You Knew: The Ultimate Collection of Tips, Tactics, and More for Getting a Greal Deal

Another example for authors

This example of a double-barreled question shows an author who tried to test a subtitle and a book cover design at the same time.

Double-barreled questions often combine a book cover with an element like title or subtitle. This is a mistake.

Even though the design difference is subtle, some respondents reacted to the arrow design, while others responded to the subtitle text. And once again, those who only wrote responses to one element were likely still influenced by their feelings about the other. Every respondent used different criteria to make a choice, meaning that the winning vote tally is unreliable.

Here’s a better example of a book cover design poll because the design is the only variable. The title, subtitle, and author attribution are the same, so respondents are only reacting to the visual elements.

A picture of not a double barreled question between two book covers and which ones more appealing. This is more of a design aspect, one Option has different hues and positioning and the other one is dark.

Have you made the mistake of asking a double-barreled question? If so, don’t feel bad — it’s a common error. But now that you know what a double-barreled question is, how to recognize one, and how to fix it, you can poll with confidence.

FAQs about double-barreled questions

What is an example of a compound question?

A compound questions asks two distinct things but only allows for a single answer. So an example might be, “Do you like your car and commute?” A survey respondent might like their car but hate their commute, or like the commute but dislike their car. How should they answer this question? Because respondents (and you) don’t know, your results will be murky.

What is a leading question?

A leading question prompts or encourages a respondent to answer in the desired way. A leading question subtly suggests the wanted answer. For example, a lawyer might ask a witness, “this firearm was the one you saw, correct?” By adding “correct” and through the lawyer’s intonation, this generally leads the witness to answer in the affirmative.

How are double-barreled questions used in law?

Sometimes a double-barreled question (called a compound question) may raise an objection if the witness may be unable to provide a clear answer to the inquiry. As we noted in the examples above, this can usually be corrected by separating the double-barreled question into two distinct questions.

What is a fallacy of many questions?

The fallacy of many questions is when someone asks a question that presupposes something. For example, if you asked, “where do you like to party?,” it would be considered fallacious because it presupposes the person you’re asking does indeed like to party. This may not be the case; the respondent might prefer quiet nights at home.

What are ambiguous questions?

Ambiguous questions are questions where is no specific query being asked. An ambiguous question could be interpreted several ways because the wording of the question does not clearly define the subject or object. For example, “Did you see the movie last weekend?” is an ambiguous question because it doesn’t specify which movie. Ambiguous questions generally lead to more questions, not straightforward answers.

What are assumptive questions?

Assumptive questions assume something about the person who’s being asked. Assumptive questions are most commonly seen in sales. For example, “how many orders can I put you down for?” assumes that the person being asked wants to put in some orders, and the asker only needs to know how many.
