Surveys have become one of the most popular tools in UX research. Their appeal lies in their ability to quickly reach a large number of respondents and generate numerical data that departments across organizations readily understand. However, with the rising use of surveys, researchers also face significant challenges such as survey fatigue, low response rates, and quality issues. To master UX research, particularly survey usage, it is crucial to grasp both the strengths and limitations of surveys and to apply strategies that avoid common pitfalls.
Why Are Surveys So Popular — and What Are Their Limitations?
Surveys are favored because they are faster and easier to deploy than one-on-one interviews. They seemingly provide a broad sample and quantifiable results, giving an impression of objectivity and reliability. Additionally, the advent of automated tools has simplified creating and distributing surveys, contributing to their explosion in popularity.
However, this widespread use has led to problems:
- Declining response rates: From 1997 to 2018, responses to phone and online surveys dropped considerably due to respondents’ reluctance to engage repeatedly.
- Survey fatigue: Respondents often feel surveys are repetitive, confusing, or tedious which affects their willingness to participate and the reliability of their answers.
- Superficial answers: Unlike interviews, surveys don’t allow for probing or clarifications, resulting in less detailed and nuanced responses.
- Hidden biases and errors: Question phrasing, order, and sampling biases can skew results without obvious signs.
- Misinterpretation of numbers: Survey data can be misread or manipulated, creating a false sense of objectivity.
Because surveys can be “treacherous water,” researchers must approach them with caution.
Key Strategies to Avoid Common Survey Mistakes
1. Consider If a Survey Is the Right Method
Before launching a survey, ask:
- Do we need quantitative data about how many or how often something happens?
- Or are we seeking qualitative insights into why people behave or think a certain way?
Surveys excel at collecting quantitative data but often fail to capture the deeper motivations or feelings behind respondents’ choices. For “why” questions, interviews, focus groups, or ethnographic research may be more effective.
For example, if you want to understand why people smoke, a survey with an open-ended question puts the entire cognitive effort on the respondent, which might not yield helpful insights. Instead, grounded options based on previous qualitative work improve clarity and response quality.
2. Differentiate Between Attitudinal and Behavioral Data
Surveys rely heavily on self-reported data, which may not always reflect reality.
- Attitudinal data reflects what people say they think or feel.
- Behavioral data reflects what people actually do.
Often, there’s a discrepancy: people’s claimed preferences or habits might differ from their real actions. For example, a study showed that although people claim to prefer positive news, their actual behavior favors consuming negative news.
Whenever possible, behavioral data should be collected through analytics or direct observation rather than surveys.
3. Design Surveys to Be Short and Focused
Lengthy surveys with many questions exhaust respondents and increase the likelihood of careless or incomplete answers. Ask yourself:
- Can the survey be cut from 20 questions to 10 or fewer without losing essential information?
- Are there filler or redundant questions that don’t contribute meaningful insights?
Timing a test respondent can reveal if the survey is too long. Aim for completion within 10 minutes to minimize fatigue.
4. Avoid Complex and Confusing Question Formats
Certain question types frustrate respondents and reduce completion rates:
- Grid questions requiring multiple answers along rows and columns can overwhelm and slow respondents.
- Overly hypothetical questions about uncertain future behaviors tend to generate unreliable responses.
Questions should be straightforward, easy to understand, and quick to answer.
5. Mind the Question Order to Prevent Bias
The sequence of questions impacts how respondents interpret and answer them. For instance, presenting a question about “balanced diets” before asking about “fruit consumption” may prime respondents to provide healthier answers than they otherwise would.
To reduce such biases:
- Carefully consider which questions come first.
- Test different question orderings.
- Avoid leading or loaded questions that push respondents toward certain answers.
6. Conduct Cognitive Interviews Before Launch
The most foolproof method to improve survey quality is to conduct cognitive interviews ahead of time. In this process, a participant takes the survey while verbalizing their thought process in real time. This helps identify:
- Ambiguous or confusing questions.
- Unexpected interpretations.
- Difficult or frustrating sections.
Cognitive interviews serve as a rehearsal, revealing pitfalls unseen by researchers and enabling fixes before mass distribution.
Conclusion
Surveys are powerful but double-edged tools in UX research. While they offer speed and quantifiable insights, poorly constructed surveys lead to low-quality data and disengaged users. Mastering survey design requires carefully evaluating when to use surveys, focusing on simplicity and clarity, avoiding biases, and pre-testing with cognitive interviews. By sidestepping these classic pitfalls, UX researchers can unlock accurate, actionable customer insights that truly inform product decisions.
