Current difficulty to formulate complex systems may be resolved by introducing scale constraints thanks to the development of advanced information technology. This paper concerns the identification of the first principle equation that governs complex system beviour by applying machine learning and trial study of the relationship between the public affinity and earthquake risk. The basic research of the discovery of the first principle equation has been made in the area of artificial intelligence, a kind of engineering. This outcome was extended to socio-psychology. Thus the framework is considered to be a symbiosis of natural and cultural sciences.
