Project Outline

We study a new methodology for applying statistical analysis to assess an AI's performance and adaptability to society. Human activities such as natural language and financial markets have statistical properties characterized by power laws. Using these properties, we focus on the differences in behaviors and outcomes between AIs and humans to examine the societal impacts, capacities, and limitations of AIs.

Achieving these goals involves two themes. The first theme investigates quantitative analysis with respect to power laws on models of human activities such as natural language and financial markets. We seek to clarify the divergences between pseudo-data generated by AIs and real data on language and investment. The second theme applies insights from the first theme to the investment field. We suggest improvements in social design and legal systems in the AI era. Because the first theme involves a technical study and the second applies the resulting understanding to society, the two themes constitute an example of a coevolutional research platform.
