The ‘Participatory Revolution’ of the past decades has caused not only a surge in political activism, but more importantly a reconsideration of the relevance of the level of political engagement: individual and collective levels of activism have started competing for political participants. In this context, a close analysis of the French case might reveal whether it is political involvement at the individual level, more than at the collective one, that drives the country's strong political activism. The testing of this political behavior paradigm will provide important conclusions on the validity of the literature on social capital, questioning the positive correlation between high levels of conventional or unconventional political activism and high levels of associationism and collective activity in social and political organizations.
