Priming Bias
Priming bias is the influence that an earlier stimulus (question, image, word) has on how a respondent interprets or answers later questions.
Priming is a specific subtype of order effect, focused on the semantic activation of concepts. Asking about politics before consumer preferences activates political identity, which then shapes brand answers. Asking about price before quality reframes the whole interview around cost-consciousness. Priming is particularly important in concept tests and brand research, where small wording differences upstream change downstream measurements substantially. The cleanest research designs avoid priming entirely by counterbalancing or by collecting attitudes before any context is provided.
Example
A pricing study: Group A is asked 'How important is value for money?' before seeing a $99 price; Group B sees the price first. Group A rates the price 'fair' at 62% vs Group B at 51% — a priming-induced 11-point gap.
