Collective action is (fundamentally) a problem of moral, political or ideological consensus of meta-preferences or emotional coordination. It is also a problem of negotiation and the intensity of preference-dependent cooperation (ordering individual and collective results). Even though collective action depends on the ability to take strategic interaction and this covers rational (interests) and non-rational motivation (reasons, passions and social norms), group size constitutes a great impediment for organising mass, long-lasting action, produced bottom-up and not being dependent on controlled selective incentives by an organised minority.
