Branching Survey Design: How to Build Surveys People Actually Finish
Key Takeaways Branching exists to remove questions, not add them. The goal of every branch is a respondent who never sees an irrelevant question â not a more elaborate survey. Design the ânoâ path as carefully as the âyesâ path. Most abandoned branching surveys fail on the answer the designer didnât plan for, not the one they did. Shallow beats clever. Two or three branch levels cover almost every real use case; anything deeper usually means the survey is trying to do too much. Every path needs to be walked, not just the main one. A branching survey thatâs only ever tested top-to-bottom will have broken paths nobodyâs found yet. A branching survey shows or hides questions based on how someone answers the ones before it â so a respondent who says ânoâ to owning a car never sees three follow-up questions about their commute. Done well, it feels like the survey is paying attention. Done poorly, it feels like a maze: dead ends, questions that donât make sense given what was already answered, or a âbackâ button that undoes more than intended.
