Trajectories of Collective Action and Social Change

Social identities and movements change over time and in relation to each other, and these trajectories are contested and under-theorised. The Queensland Longitudinal Survey has recruited N ~1000 each year from 2022 to 2025, with ~20% of respondents longitudinally retained and ~80% new participants each year. Participants report their support for democracy and political violence, along with their activism for various causes and (for their preferred cause) their perceptions of movement failure and success, their past behaviour, and their future intentions. In the present talk I present new theories and methods that illuminate multi-dimensional trajectories of psychological change.
