Thought 1: Correlation/causation. It's not clear if the house causes the higher likelihood of failure or if the folks who are more likely to fail are drawn to the house. I can see arguments for both.
Thought 2: I don't think Wired is trying to write a story about intrigue as much as using the Senior House story to illustrate the larger trend of universities becoming more homogenous.
Writing a story that says "Universities are getting boring. 3 universities closed their counter-culture houses in the past year. Here's some quotes from people" is going to be, frankly, boring to read. On the other hand, a story that says "3 universities closed their counter-culture houses in the past year. Here's the story of one of them" is going to be much more compelling. It makes the story more personal, and therefore easier to understand and relate to.
