It does seem surprising that none of the low SES women had any idea this was a party dorm. Even back in the mid-2000s, most colleges had website and many small towns probably had other kids that went to IU and would offer advice. Nowadays I doubt this is much of an issue, as it seems that kids get on social media to find roommates and learn about the various dorms. But if these women entered college in 2004 there was a lot less social media and college websites were not as useful. It is hard to remember that 10 years ago, there was no Facebook.
