” You Can Pick Your (Best) Friends”
FRIDAY May 6 4:30 King 221
In this talk, he will present some results from a recent collaboration with evolutionary psychologists and computer scientists on questions of how people choose friends and prioritize among those friends. Specifically, he will describe analysis of large samples of MySpace profiles containing “Top Friends” lists, in which an individual selects a small subset of his or her friends and organizes them into a ranked order of that individual’s choice. Different classes of behavioral hypotheses give rise to very different graph-theoretic structures in the best-friend network, and we can use these ranking data to provide supporting evidence for some of these theories.
