Valence Secession? Voting Shocks and Independence Support in Scotland

National identifications, cues from political actors, and cost-benefit calculations have been pointed as the main determinants of secession preferences. However, a recent surge in independence support in Scotland suggests that abrupt political changes may also affect these preferences: Brexit and the differentiated management of the Covid-19 pandemic by the UK and the Scottish governments are named as causes of the first independence sustained majority registered by polling in Scotland. In this article, I discuss how voting shocks may affect the levels of support for independence, revise the evidence that sustains these claims, and analyse how they have changed the profile of the pro-independence voter. The effect of these questions has substantial implications for a possible second independence referendum in Scotland, as well as for the broader debate on the sources of secession support.
