Whenever a problem is complex, binary ballots are not the best. Politicians, however, often reduce everything to either an “option ‘x’ or ‘y’?” choice or an “option ‘x’, yes or no?” question – as in “the eu withdrawal or ‘no deal’?” – because if ‘x’ is what they want, such a stark dichotomy increases the chances of their success.
The outcome of such a vote, however, is often unclear: do people really want ‘x’, or do they just dislike ‘y’? And would they have preferred ‘z’?
