How did people’s expectations of the consequences of Brexit affect their vote?

A new paper by Stephen Fisher and the Unit’s Alan Renwick sheds fresh light on these issues, examining what people thought they were voting for in 2016 and how that affected their vote choice. In this post, the authors summarise the findings and draw out lessons for today’s debates.

With increasing discussion of the possibility of the UK holding another referendum on its relationship with the EU, it is important to better understand what happened at the last one. Understanding how voters made up their minds in 2016 could provide insights into how another referendum might play out. Also, one of the key arguments against another referendum is to maintain respect for the outcome of the previous one. What it means to respect that outcome depends on understanding why the UK voted to leave the EU.

In our recently published paper in Acta Politica (available free-to-view here), we focus on the role of voter expectations of the consequences of leaving the EU. Following previous research by Sara Hobolt and John Curtice showing that attitudes to the EU, including expectations regarding Brexit, were the most powerful and proximate predictors of vote choice at the referendum, we wanted to investigate further how Brexit expectations mattered, and whether it made a difference if voters did not have clear expectations. In particular, we wondered whether, perhaps because of risk aversion, uncertainty about the implications of leaving the EU was associated with Remain voting.

In April 2016, before the referendum campaign, the British Election Study (BES) internet panel asked people what they thought would happen with respect to various different economic and political outcomes in the event of the UK leaving the EU. For most of the outcomes the modal response was to say that things would stay ‘about the same.’ These outcomes included the economy, unemployment, international trade, risk of terrorism, rights for British workers, personal finances, British influence abroad, and the risk of big business leaving the UK. There were just two exceptions. There was a slight tendency for people to think that Scottish independence would be more likely and a strong expectation that immigration would be lower after a Brexit. Continue reading
