This article challenges the prima facie differences between the Scottish independence and pro-Brexit movements, drawing similarities based on shared promotion of nationalism, incorporation of populism, and policy radicalism challenging consensuses over austerity/immigration.
The analysis tests four hypotheses: first, their respective supporters hold nationalist beliefs; second, their supporters adhere to different but relatively radical policy preferences (tested on three dimensions: economic, cultural, immigration); third, their supporters adhere with populism; and fourth, their supporters are cynical towards perceived experts. The article finds the expected nationalist support, as well as supporters of independence/Brexit holding more radical policy beliefs compared to anti-independence/anti-Brexit voters. Furthermore, the analysis reveals a clearer picture of anti-expert and anti-elite populism support for Brexit, with little evidence showing these being features of Scottish independence support. This leaves the conclusion of some voter-level similarities between supporters of both movements, but also differences in the levels of populism among their respective voters.
