El trabajo plantea, a partir de la movilización estudiantil chilena en más de una década, un análisis de su injerencia en la revuelta iniciada en octubre 2019. Sobre la base de materiales de investigaciones previas, se analizan tres coyunturas polémicas: la rebelión pingüina de 2006, el movimiento estudiantil de 2011 y el movimiento feminista de 2018, para definir sus alcances culturales. Se concluye identificando consecuencias culturales en la subjetividad, en los estilos de protesta, en las reglas del sentir y en la economía moral de la ciudadanía, que generaron condiciones político-culturales favorables para la coyuntura crítica de octubre.

The following work problematize the constructionist assumptions that underlie the theorization and sociological research of public problems. As such, we review the onto-epistemic components of constructionism and their relationship with the main authors in this research field, with the objective of problematizing them based on pragmatist proposals in the same field. Our proposal is that research on public problems is strengthened by combining both approaches. To prove the point, our argument runs as follows. After the introduction in which we situate the problem, we present the constructionist foundations from the work of Gusfield. Later, we discuss French pragmatist proposals, following D. Cefaï. We finish with a discussion about the relationship with the empirical, analytical, and political scope in the study of public problems.
