This document discusses best practices for survey question and response design to reduce bias. It provides guidelines for writing good survey questions, such as making sure the question is clearly understood, the response needed is communicated, and respondents have the information to answer. For responses, quantitative anchors on scales (e.g. 1-5 ratings) may reduce bias compared to qualitative anchors by making intervals equal and responses more reliable. Odd-numbered scales allow respondents to choose rather than be forced to one alternative. A neutral middle option on scales is optimal, as it acknowledges differing opinions but too many options can reduce cognition.
