Forced vs. Non-Forced Response
When some respondents cannot have an opinion, non-forced questions improve the accuracy of the results.
Do respondents not want to answer — or do they simply have no opinion?
"Don't know" / "Not applicable"
✓Use for factual questions and knowledge questions.
✕Not when measuring attitudes and opinions.
Skip logic
Deliberately steer so that respondents only get questions they can actually answer — rather than forcing responses.
Rule of thumb: Questions without a "don't know" tend to yield more accurate data — but only if respondents actually have an opinion.
