I never said that Penn secret societies or senior societies were not the same as Yale’s; in fact I know very little about Penn’s society life. I was replying to a previous poster about the point that Yale’s secret societies fulfill the role of a larger Greek life on campus, which it doesn’t. Secret societies play a very minimal role on Yale’s campus (contrary to popular stereotypes), and a far less obvious role than Penn’s Greek life does on its campus based on obvious raw % of students involved.
