This study shows that China’s wheat and rice regions have different cultures. China’s rice regions have several markers of East Asian culture: more holistic thought, more interdependent self-construals, and lower divorce rates. The wheat-growing north looked more culturally similar to the West, with more analytic thought, individualism, and divorce. Furthermore, Table 4 presents an instrumental variable regression instrumental variable regression showing that climatic suitability for rice significantly predicts all of the cultural variables in this study, which suggests that reverse causality is unlikely.
Unresolved questions: 
There are still unresolved questions with the rice theory. For example, studies can test whether irrigation is central to the effect of rice by comparing paddy rice with dryland rice cultures, which grow rice without irrigation. Studies can also explore how rice differences persist in the modern world, whether through values, institutions, or other mechanisms.
An obvious follow up can be to explore violence (homicies) within those cultures.
