The writer of this paper critically analyzes the ways in which De Munch and Korotayev start out by explaining that it is
difficult to
research across cultures because of "cross-
cultural pollenization" that is, one culture tends to absorb some traits of the other. They point out that without adequate controls, the research can give both false confirmations of the hypothesis as well as false negatives. This paper is a negative critique of Cultural Units in Cross-Cultural Research.
