Use the four-stage survey response process to diagnose weak questions.
A respondent is not a database query. They interpret your words, search memory, estimate, then fit that estimate into your scale. Each step can create error. To improve comprehension, use concrete nouns and define the reference object. To improve retrieval, use bounded time periods and observable events. To improve judgment, avoid loaded terms and impossible averaging. To improve response mapping, make options exhaustive, mutually exclusive, and aligned with the way people naturally know the answer. The four-stage model gives you a practical checklist for item repair.
