The structure of Likert scales, specifically the inclusion of a midpoint or 'no idea' option, significantly influences consumer responses, particularly for sensitive product categories. This innovation & markets research insight is drawn from a 2026 study published in Humanities and Social Sciences Communications. Using Online survey with 1333 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When researching consumer attitudes towards sensitive products, avoid a one-size-fits-all approach to Likert scale design; tailor the scale to mitigate potential biases.

Key Findings
- 01The optimal Likert scale structure for measurement validity is dependent on the sensitivity of the issue being measured.
- 02Response bias and social desirability bias are important considerations when choosing Likert scale formats for sensitive topics.
Application
Design takeaway
When researching consumer attitudes towards sensitive products, avoid a one-size-fits-all approach to Likert scale design; tailor the scale to mitigate potential biases.
How to apply
Before deploying a consumer survey, pilot test different Likert scale formats to see which yields the most nuanced and reliable data for your specific research question and target audience.
Project actions
- 01When designing your survey, think about whether your topic is sensitive and how that might affect responses.
- 02Consider offering a 'no idea' or 'prefer not to answer' option if your topic could make participants uncomfortable.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Large sample size provides statistical power.
- +Systematic comparison of multiple scale formats across different product sensitivities.
Limitations
The sample was composed of students, so results might not apply to all age groups or demographics. The specific products studied (beer, coke, energy drink) might have unique associations that influence responses.
Reliability & validity
The study aims to improve measurement validity by examining how scale structure affects response patterns, thereby enhancing the reliability of findings related to consumer attitudes.
Think critically
How might the cultural context of participants influence their response to sensitive issues and their interpretation of Likert scale options?
Design Principles
"Scale design should be context-aware, adapting to the psychological and social sensitivities of the subject matter to ensure data integrity."
Understanding how scale design affects responses is crucial for accurate market research. Inaccurate data can lead to flawed marketing strategies, misallocated resources, and missed opportunities.
What This Means for Your Design
How you ask questions in a survey matters! If you're asking about something sensitive, like alcohol, the way you give people choices (like having a 'don't know' option or an even number of choices) can change their answers.
How to use in your project

Paragraph starter
The selection of appropriate response scales is critical in design research, as demonstrated by Kurtuluş et al. (2026). Their findings indicate that Likert scale structures, including the presence of a midpoint or 'no idea' option, significantly impact consumer responses, particularly when addressing sensitive issues. This highlights the need for researchers to tailor scale design to the specific context of their inquiry to mitigate response and social desirability biases and ensure the validity of collected data.
