Before revision:  Because early agents are disproportionately influential, standard network structures can lead to herding on incorrect beliefs . The probability of mislearning increases when link densities are higher and when networks are more integrated. When actions can only communicate limited information, segregated networks often lead to persistent disagreement between groups.
After revision:  Because early agents are disproportionately influential, standard network structures can lead to herding on incorrect beliefs and we compute comparative statics of the probability of herding with respect to network parameters. When networks are segregated, divergent early signals can lead to persistent disagreement between groups.
