As I was looking for some background information on the fraternity/sorority community at Princeton, to try to better understand the recent ban on freshmen participating in any aspect of the recruitment process, I came across this five-part story from the Princeton student newspaper. It is likely that this series may have triggered some of the initiatives that led to the recent ban. Although the Princeton administration sees otherwise, these articles make a very strong case for having a strong connection between the institution and the fraternities/sororities.
I am also curious about how Princeton justifies its differentiation of the fraternities/sororities with the selective eating clubs. Neither group is recognized by Princeton, but the open relation with the eating clubs has allowed them to evolve with changing times. The confrontational approach to the fraternities/sororities has done a lot to keep them developing a symbiotic relationship that would benefit the entire community.
