In 2001, as part of a research group project called “Thursday Meeting” that Dr. Masakatsu Murakami has been organizing since the early 1990s, we conducted three public interviews with Dr. Chikio Hayashi about his academic experiences and philosophy of statistics and science.
The first and third interviews were about the history of Dr. Hayashi’s research and the invention of the Hayashi method of quantification, which have already been published in the Japanese Journal of Bahaviormetrika (Takahashi, 2004) and The Society and Survey (Takahashi, 2012). This is the second open interview with Dr. Chikio Hayashi about his experiences and thoughts on collaborative research with researchers in various fields such as criminology, linguistics, public opinion research, psychology, economics, marketing research, forestry, medicine, and economics. Since the late 1980s, Dr. Hayashi has been putting forward the idea of “Science of Data” and the importance of looking at the total process from the design of data collection, pre-testing, data collection, data cleaning, data aggregation, data analysis, and summary for policy making, and the cyclical improvement is especially emphasized. This article should make readers aware of the major difference between his “Science of Data” and the superficial techniques of “data science” that are currently in vogue.
