Are Remainers brighter than Brexiteers? People who voted 'Leave' in the 2016 referendum have lower cognitive ability, study claims

What exactly tipped the Brexit referendum in the favour of the Leave campaign on voting day – June 23, 2016 – may never been clear cut. But a new study suggests the intelligence of voters – and their susceptibility to being duped by misinformation – played a part. From a sample of Brits, researchers looked at how exactly they voted, as well as their intelligence, as determined by performance in cognitive tasks. They found a link between high performance in the tasks and voting Remain, which suggests people who wanted to stay in the EU have higher intelligence. However, the study method only looked at data from just over 6,000 referendum voters – a far cry from the 33.5 million who cast their ballot that day.
