Experimenters took advantage of a natural situation to study the effect of "propinquity," or close physical position, on friendships. The participants were 40 first-year students who were attending an orientation meeting at their university. None of the freshmen knew each other before the meeting, and they were assigned to sit in one of the 40 classroom seats at random. The researchers recorded who sat by whom. Two months later, they asked each person about which of the other students, among the 40 freshmen at the first meeting, they had become friends with. The researchers compared friendship rates between people sitting next to each other at the first meeting with friendship rates between people sitting more than one seat away from each other. The students were more likely to have become friends with people in neighboring seats. (Adapted from Back, M. D., Schmuckle, S. C., & Egloff, B. [2008]. Becoming friends by chance.
