Research has found that actors use social networks to access diverse sources of information on one hand, but on the other hand, social networks have also been connected with mimicry in choices leading to cascades. We examine this question in a longitudinal network setting with actors making choices and find that uncertainty has a strong moderating effect. In more uncertain conditions, actors tend to use networks to make choices more similar to others than in conditions of less uncertainty. Jelcodes:M19,N00
