When making a survey there are different types of questions that can invite the respondent to answer to get the information needed. There are direct questions, open-ended questions, or double-barred questions. The important thing to get appropriate results is not to bias the question because it encourages people to respond to the question in a particular way. In the case of yes or no questions, it would violate the concept of avoiding negative terms.
