# Avoid design-biased market research issues I understand that you are asking how to identify and avoid biased design in market research. When conducting reliable market research, the goal should be to obtain true and objective data, not to manipulate the results. ## Common biased questionnaire design methods (should be avoided)： 1. **Guided questions**: Use vocabulary that hints at the expected answer *For example: "Don't you think our products are better than our competitors?" " 2. **Hypothetical questions**: Contains unproven premises * For example: "Why do you like our new features?" "(Assuming the interviewee already likes it) 3. **Double question**: Ask two things in one question * For example: "What do you think of the quality and price of our products?" " 4. **Lack of balance options**: Only positive options are available * For example: there are only "very satisfied", "Satisfied", and "More satisfied" options. ## Suggestions for designing objective market research： -Use neutral language - Provide a complete range of options -Test different concepts separately -Conduct a trial survey to verify the objectivity of the questionnaire Responsible market research should pursue objective and truthful consumer feedback, rather than creating data that is biased towards specific conclusions.
