One Question Too Many: Why Double-Barreled Questions Skew Results

We can only do good research if the questions to investigate are clear. Surveys should not confuse respondents, as that will impact your data quality. The double barreled banning is when you ask about two different ideas in the same question but receive only one answer.
It appears to be quite efficient at first glance. It actually makes everything less certain and less effective.
Double Barreled Question − What is It?
Double barreled question is one which combines two unrelated subjects into a single question. This means that respondents have to answer on the spot, even if they disagree with one of those parts.
Questioning someone if they are “happy with the price and quality” implies their opinion of the two is the same. Often, it isn’t.
Why That Isn’t the Type of Question Which Works?
The problem with a double-barreled question is that it creates ambiguity. There is no clarity about which aspect the respondent is reacting to.
This leads to:
- Confusing or unreliable data
- Misleading averages or trends
- Poor decision-making
Conjectures formed from ambiguous results can be dangerous.
Questioning Double Barreled: The Effect on Respondents
This leaves respondents not knowing how to respond. Some guess. Others skip the question. Both outcomes damage data quality.
Double barreled questions also increase frustration. If they cannot answer the question and the engagement dies, the response rates will fall.
Common Places They Appear
These are the kind of questions that creep into surveys unnoticed. They appear in:
- Customer satisfaction surveys
- Employee feedback forms
- Market research questionnaires
The risk is greater whenever fast is valued over clear.
Identifying a Double Barreled Question
A simple test helps. Does the question contain an ‘and’? If it does, pause.
If you want to spot a double barreled question, see if you can pick out:
- We are measuring two ideas at a time
- If you ask me two questions, one answer cannot be enough for both of them.
If yes, the question needs to be reformulated.

How to Fix the Problem
The answer is straightforward: break the question in two.
Split a double-barreled question into two questions. Focus on one single idea for each.
This approach:
- Improves clarity
- Increases response accuracy
- Makes analysis easier
Clear questions produce strong insights.
Why Clarity Always Wins
Short surveys are good. Clear surveys are better. If question design is compromised, then the data is also compromised.
The use of double-barreled questions provides less value and this practice weakens research quality and protects decision-making.
Final Thoughts
Surveys must minimize the ambiguity, not maximize it. This double-barreled question removes clarity and trust in data.
Researchers elicit clearer responses and usable insights by asking one question at a time.
