In 2016, the UK held a referendum on our membership of the EU. Problem number one: the question was vague. It was a this or not this binary option. At no point was a choice offered on the wide spectrum of possibilities encompassed by the not this option. But that’s not to say that the various Leave campaigns failed to provide opinions on what they believed would happen. They were often contradictory, regularly disreputable and sometimes just downright untruthful. But a picture was painted, even if the result did rather resemble a Rorschach test. A test that elicited visions of joy and prosperity from 17 million participants, and doom and gloom from the other 16 million people who took part.
