Query: Diversity and Collective Action   We elucidate the dynamics of ongoing collective action among intentional
agents with diverse beliefs and imperfect information. Their decisions on
whether or not to contribute to the collective good depend not only on the past
but also on their expectations as to how their actions will affect those of
others. We show that in attempts at collective action the onset of overall
cooperation can take place in a sudden and unexpected way. Likewise, defection
can appear out of nowhere in very large, previously cooperating groups. These
outbreaks mark the end of long transient states in which defection or
cooperation persists in groups that cannot sustain it indefinitely. Diversity
of beliefs among individuals acts as an additional source of uncertainty and
instigates the outbreaks.
