Good wording uses ordinary language, a clear time frame, one idea at a time, and balanced alternatives. It also names enough of the actual policy-actor, action, and important tradeoff-to make the response interpretable. A slogan such as "safe neighborhoods" may attract broad support while revealing little about a proposed surveillance rule.

Asking about a recent school scandal before asking whether the superintendent is trustworthy may lower ratings. Split questionnaires, randomized blocks, and reversed response orders can detect the effect.

Response bias concerns the reporting process. People may overstate voting, tolerance, charitable giving, or compliance with law because those answers appear socially acceptable.

The response format should match the idea. A yes-or-no choice may create false certainty when strength matters.

Keep the sources of error separate: wording determines what was asked, order shapes the context, and response bias affects what people report. Probability selection cannot rescue a misleading item administered to everyone.
