The study of the Pruitt-Igoe housing project in St. Louis by Yancey and his colleagues concluded that the architectural design of the project produced
◦ such a thriving set of informal social networks that it is hard to understand why the project did not work.
◦ an atomizing effect on the residents' informal social networks.
◦ an example that led many of the young residents to pursue a career in architecture.
◦ no effects either positive or negative on the project.
