According to a 2005 issue of the Journal of Association Leadership, ULI "taps into the experience and expertise of its members to advance real estate development practice and to change the urban landscape using many of the principles identified in The Wisdom of Crowds to solve problems — cognition, cooperation, and coordination problems." With a membership representing "26 disciplines and 13 industry sectors, working in the public interest and private enterprise, the institute documents best practice by aggregating members’ collective wisdom and structures communities of practice as self-organizing systems."
