The brillouin measure of an author's contribution to a literature in psychology

The Brillouin measure of an author's importance to a subject literature relates closely to that author's total contribution to the literature. Synthetic authors (those with negative entropy) are generally highly cited but citation ranking does not correlate well with synthetic strength. Synthetic authors do not concentrate in highly productive journals. The analysis is based on a 40-year bibliography of the psychological phenomenon of extinction containing 894 distinct authors and 877 items.
