The Santa Fe Institute was created to be a visiting institution, with no permanent or tenured positions, a small group of resident faculty and postdoctoral researchers, a large visitors program, and a larger group of external faculty affiliated with the Institute but located at other institutions. The motivation of this structure was to encourage active turnover in ideas and people, allowing the research to remain on the cutting edge of interdisciplinary science.[1][2][3] Today, the Santa Fe Institute continues to follow this organizational model.
