Perspectives

SOCIAL SCIENCE:
Ignorance, Knowledge, and Outcomes in a Small World

Mark Granovetter

Thirty-six years ago, Stanley Milgram in his famous "small world" experiment found that every individual in the United States is linked to every other through a short chain of social ties, with an average chain length of six people. In a Perspective, Granovetter discusses a large-scale study of 60,000 e-mail users (Dodds et al.) that confirms Milgram's original findings and delves deeper into understanding the social networks that connect us all.
