Scriven number In 2012, an article published in the Journal of MultiDisciplinary Evaluation posed the necessity of a Scriven number. Similar to an Erdős number, a Scriven number describes a person's degree of separation from Dr. Scriven through published collaborations directly with him or with others who have collaborated with him. Michael Scriven holds the unique Scriven number of 0 while any persons publishing directly with him hold a Scriven number of 1. In addition, those who have published with those individuals who have directly published with Dr. Scriven hold a Scriven number of 2. This algorithmic format continues indefinitely. For those published with multiple papers with paths to Dr. Scriven, the shortest path will serve as the Scriven number. This type of number is hypothesized to help centralize the field of evaluation.
