BRITAIN IS outside the European Union after a referendum to leave in 2016, and now the Scots are eyeing another referendum on whether to remain in the United Kingdom. But back in 2016, few Brexit supporters contemplated that the country might also leave arrangements like the European Economic Area or customs union, which it has. How did it come to this? One factor, obviously, was the choice of the majority of voters (to Remainers’ dismay). But a bigger, less obvious factor was the ballot and voting process itself. The conventional binary voting method is outdated and needs to be modernised to produce outcomes that hew to the will of the people.
