S3E19: Social Network Analysis: Making Connections with Tracy Sweet


In this week’s episode Greg and Patrick have a wonderfully engaging conversation with social network analysis expert Tracy Sweet who is an Associate Professor in the Department of Human Development and Quantitative Methodology at the University of Maryland. Tracy patiently helps us understand what social network analysis is, and how it can be used to better understand the complexities of human behavior. Along the way they also discuss sliding into DMs, fax machines, older millennials, baboons, too much math, inside voices, penguin data, swiping left, probation advice, unreciprocated social isolates, Wordle, the floss dance, power, and talking to your dog.
