  We study the influence of hesitating agents in the Axelrod model by
introducing an intrinsic noise, which is proportional to the disagreement
between the interacting agents, and thus coupled to the dynamics. Our results
show that, unlike the effect of the cultural drift where the noise is just
controlled by an external parameter, the intrinsic noise never allows the
system to reach a frozen state in the thermodynamic limit. Moreover, we show
that when the intrinsic noise affects the agents' variables, the system's
behaviour is also different from the case when it affects the network of their
interactions.
