[HM] Benford's Law
Posted:
Jul 19, 2000 9:37 PM


There is a "law" commonly called "Benford's Law" after Frank Benford who wrote a paper (*The Law of Anomalous Numbers* was its title) about it in 1938 (Proc. Am. Phil. Soc. vol 78, p551ff), with no indication that it was not original with him. Many other papers about this "first digit phenomenon" appeared in later years, usually naming it after Benford, but it had in fact been announced and discussed by Simon Newcomb sixtyseven years earlier (Amer. J. Math vol 4, 1881, p3940). When I wrote a history of the attempts at proving this law (*The First Digit Phenomenon*, Amer. Math. Monthly vol 83, 1976, pp 521538) I had the pleasure not only of announcing for the first time in print, so far as I knew, that it had been anticipated by Newcomb, but of comparing Benford's Law with an alternate, though similar one I dubbed "Stigler's Law", which was a slightly different proposed frequency distribution of first digits in the tables of data that have reason to exhibit the phenomenon in question.
However, the Stigler I referred to was apparently the real author of that "law", or at least he was the one who had written me about it (privately), explaining it had been the result of a lunch table conversation between himself and other members of a certain group of wartime statistical analysts of military efficiency in 1944, the actual calculation having been made by Stigler himself after the lunch was over. This 1944 Stigler was the famous economist George Stigler (Nobel Laureate in later years), the father of the statistician Stephen Stigler whose Law of Eponymy is the subject of the exchange I reproduce below.
George Stigler was also the author of another "law", this one a law of economics, the name of which I've now forgotten. This Stigler law says that all (economic) elasticities are small, if not zero. Since the assertion is manifestly impossible his (humorous, but nonetheless serious) essay on the subject is worth reading, and appears in one of his two or three collections of more or less nontechnical essays on economics. I believe there is no question that this particular law of economics is properly named Stigler's Law, and is unlikely to be discovered again.
