摘要：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-item measures with a large amount of data. The result of our large-scale survey (N = 3,750) showed that respondents displayed the personality traits corresponding to their own blood type more strongly than respondents who had different blood types did. This finding was consistent across all traits, and all differences were statistically significant. In our survey, the same differences in scores were found in the groups who had no knowledge of blood type personality theory, although the values were smaller. Meanwhile, the sample in this study was limited to Japanese populations. Additional research using a large, more global dataset is needed.
