A Pilot Study Using AI for Genetic Effects on Personality: ABO Blood Type in Japan/Korea

Abstract

It is estimated that genetic factors contribute to approximately 50% of an individuals personality. However, despite this estimate, statistical analyses have yet to establish a significant and consistent relationship between personality tests and genetic factors. Conversely, a large number of individuals in Japan, South Korea, and Taiwan believe in a connection between genetically determined ABO blood type and personality traits. This pilot study aimed to investigate this relationship by analyzing data from a Japanese survey (N=1,827) and a South Korean survey (N=482) using a combination of traditional statistical methods and AI. The findings demonstrated a relationship between ABO blood type and self-reported personality traits, as assessed through several single-question items, consistent with the anticipated outcomes. The findings of this study imply that the relationship between blood type and personality may extend the ABO blood type to other heritable personality traits. Additionally, this study also explores the influence of the level of interest on personality and the potential role of evolutionary psychology.
