In China's one-party bureaucracy, central directives issued by the Central Committee of the Chinese Communist Party and the State Council are the most important instrument of formal policy communication, yet their language has rarely been studied. This study highlights three politically salient varieties of directives: grey (ambiguous about what can or cannot be done), black (clearly states what can be done) and red (clearly states what cannot be done). Grey directives encourage flexible policy implementation and experimentation, black ones strongly endorse and thereby scale up selected initiatives, while red ones forbid certain actions. Together, this mixture of ambiguous and clear directives forms a system of adaptive policy communication. Using automated text analysis, I classify nearly 5,000 central directives issued from 1978 through 2017 into the categories of grey, black and red. This first-of-its-kind measurement effort yields new insights into the patterns and evolution of central commands from Deng Xiaoping to Xi Jinping.

Recent years have seen rapid developments in automated text analysis methods focused on measuring psychological and demographic properties. While this development has mainly been driven by computer scientists and computational linguists, such methods can be of great value for social scientists in general, and for psychologists in particular. In this paper, we review some of the most popular approaches to automated text analysis from the perspective of social scientists, and give examples of their applications in different theoretical domains. After describing some of the pros and cons of these methods, we speculate about future methodological developments, and how they might change social sciences. We conclude that, despite the fact that current methods have many disadvantages and pitfalls compared to more traditional methods of data collection, the constant increase of computational power and the wide availability of textual data will inevitably make automated text analysis a common tool for psychologists.
