Summary: In this nice introductory lecture to the discipline of sociology, physician and sociologist Nicholas Christakis explodes the popular myth that people are masters of their own destiny. As the YouTube blurb states, "If you think you're in complete control of your destiny or even your own actions, you're wrong. Every choice you make, every behavior you exhibit, and even every desire you have finds its roots in the social universe." 1. This insight is an expression of a fundamental tension explored in the discipline—that between the power of individual agents (i.e., agency) and the power of supra-individual forces (i.e., structure), such as the neighborhood in which one lives or one's location within a social network. 2. The second big idea Christakis explores in his lecture is emergence, or that society is something more than simply the sum of its individuals and that collective phenomena are not mere aggregations of individual phenomenon. To illustrate the concept of emergence, Christakis embarks on a discussion of social networks and other central concepts to the discipline, such as social capital. He then concludes his lecture by pointing out that while many scientific disciplines have broken up phenomenon into smaller and smaller bits, and are now engaged in an effort to put the pieces back together in order to discern how their assembly gives rise to new, emergent properties, this pattern of disassembly and reassembly has always been a central feature of sociological work.
