Abstract

Members of two "research clusters" each in social and biological science were asked how they had first learned of work they had cited in recent publications. While scientists can learn of new work via weak ties, they hardly ever did, because, it is argued, (1) a scientist's goal is to find particularly good work rather than to maximize information about all possibly relevant work and (2) scientists who are strong ties do not necessarily know identical literature.
