The socializing nature of protest events. Consequences of the 15-M protests on participants’ political engagement over time

Abstract

In spite of the widespread belief that firsthand experience with protest is able to change participants’ hearts and minds, the empirical evidence tracking actual changes after participation in protest events is scant and mixed. We examine whether participation in significant protest events increases political engagement in terms of both attitudes (interest, internal efficacy) and behaviors (later participation in demonstrations, overall political participation), and whether these effects persist over time. We use a unique panel survey that covers nine years (2010–2019) and tracks individuals before and after the major protests that took place in Spain in 2011, known as the Indignados or 15-M protests. Our results indicate that participating in the 15-M protests had a positive effect on all the studied political engagement indicators immediately after the protests and, in particular, about two years after they occurred. However, eight years after the protest events, most of these effects had faded.
