Designing Good Referendums
The practical principles for designing referendums that produce legitimate, informed outcomes — from question wording and thresholds to campaign rules and implementation.
The Question Is Everything
A well-designed referendum starts with a well-designed question. The question must be clear (voters must understand what they are deciding), neutral (it must not lead voters toward a particular answer), binary (it must have a clear yes/no answer), and actionable (the result must translate into specific policy). Many referendum failures trace back to poorly designed questions.
Brexit's question ('Should the United Kingdom remain a member of the European Union or leave?') was clear and neutral but not actionable — 'leave' meant different things to different voters. New Zealand's 2016 flag referendum used a two-stage process: first choosing among alternative designs, then choosing between the winning design and the existing flag. Multi-stage processes can solve the problem of binary choices on multi-dimensional questions.
