It is estimated that genetic factors contribute to approximately 50% of an individual's 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 i...

Genome Wide Association Studies (GWAS) are useful for comparing the characteristics of different human population groups. However, genomes can change rapidly over time when there is a strong selection pressure, such as a pandemic. The genetic information related to the immune system is thought to be very sensitive to such diseases. Therefore, it ma...

It is estimated that genetic factors account for roughly 50% of an individual's personality. However, statistical analysis has so far failed to show a substantial and consistent relationship between personality tests and genes. Meanwhile, about half or more of Japanese, Korean, and Taiwanese people feel that the relationship between genetically det...

Raw data

AI can be applied in various ways to the measurement of personality in psychology. Measuring the impact of a single gene on personality can be handled by AI technologies, at least technically, i.e., using supervised learning models of machine learning. The ABO blood type is a relatively easy biological marker to examine; therefore, people in many c...

In Asian countries, e.g., Japan, South Korea, China and Taiwan, many studies on the relationship between ABO blood type and personality have been conducted. Recently, it has been estimated that more than half of Japanese, Korean and Taiwanese people feel that this relationship is legitimate. Therefore, when data from these countries are used in per...

The relationship between blood type and personality has long been one of the more challenging issues of scientific studies. Several large-scale surveys were conducted to address the issue, and some of them had shown statistically significant associations. Presently, more than half of Japanese people feel that the relationship is legitimate. This pi...

The influence of genetic factors on personality has been actively studied for several decades. However, there is no scientific consensus about the specific genes involved, since the previous studies using multiple-item measures yielded inconsistent results. In this study, we conducted an analysis based on the phenotype of the ABO gene using single-...

The influence of genetic factors on personality has been actively studied for several decades. This pilot study analyzed data from a large-scale survey (N = 3,750) using a combination of traditional statistical techniques and artificial intelligence (AI) to examine the relationship between ABO blood type and personality. The results showed that res...
