Question order supplies context. An earlier item can prime an issue, provide information, create a desire for consistency, or establish a comparison for what follows. 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.

The goal is appealing, but the object is underspecified. If the budget question follows several stories about student awards, order may further elevate supportive considerations. An anonymous survey may also produce different answers from a public interview if residents fear appearing hostile to children.

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. The exact questionnaire is part of the evidence, not a technical detail hidden behind the headline.
