Computer Enumeration of Significant Implicational Universals of Kinship Terminology

The discovery of general patterns and their subsequent explanation is a familiar method in linguistics and other cross-cultural research. This paper addresses the computerized enumeration of significant cultural and linguistic patterns, specifically implicational universals. We dispute published suggestions that the mechanical generation of universals is inadvisable, by arguing that such claims do not distinguish clearly the noticing of a pattern with its explanation. We make use of a simple, principled method that uses permutation tests to estimate whether the discovered universals are significant. Finally, these methods are used to mine the rich kinship dataset contributed by G. P. Murdock in 1970, and to report 14 universals found therein.
