The Blood type personality
Blood type personality is based on blood group theory given by a Japanese professor ‘Tokeji Furukawa’. According to him, the differences among people’s characteristics are genetic and based on the blood group they possess. However, his ideas are not backed by scientific evidence. It is similar to the horoscope trend which is popular among people. In the same way, in the Japanese culture, people inquire about blood groups of people to assess personality and compatibility between people. Each blood group has a different personality. So, there are four types i.e. blood group A personality, blood group B personality, blood group AB personality, and blood group O personality. Their details are discussed as follows.
An Overview of Blood Type Personality
In different countries, people have different ways of understanding the personality of others. Some cultures feel comfortable relying on astrological information to understand personality. Whereas, other cultures rely on different methods. Blood type or blood group is one of these methods. The Japanese and South Korean culture likes to rely on the blood group of someone in order to understand their personality and characteristics.
In companies, among friends, and even among romantic partners, this practice is quite popular in Japan. They check compatibility by inquiring about the blood group of someone. Despite the fact, that scientifically it is not backed up and warnings have been given to the general public to not rely on the authenticity of blood group personality, its usage continues to this day. Employers select employees based on their blood group. Similarly, schools split up children based on their blood group and so on. However, it must be mentioned that this discrimination is not too severe. It is similar to the horoscope addiction some people have with no drastic implications. In the same way, the general public varies in terms of their beliefs about blood groups determining the personality of a person.
Blood Type Theory Development
The term commonly used in Japan is ‘Ketsueki-gata’ when evaluating a person and their traits based on the blood group they possess. A Japanese Professor in the 1930s published a paper stating that a blood group of a person gives an insight into the personality they possess. His name was Tokeji Furukawa. He used chi-square to test his findings. However, his motivation behind the study was to figure out why racism was done by Taiwanese soldiers. He tried to support the argument that their cruel behavior was genetic. He concluded that Taiwanese people should marry Japanese people to reduce blood type O and accordingly decrease toxic personality traits.
Masahiko Nomi revived this theory in the 1970s. He had no medical background, yet he continued to produce statistically significant findings based on the blood group theory. He was criticized by Japanese psychologists based on no prior scientific or medical background. After his death, his work was re-evaluated and it was concluded that his study was not controlled properly and had unclear methodology. Yet, his son built upon his father’s work and continued with his research.
The blood type personality is mostly dismissed in the scientific community. It is considered to be a pseudoscience and superstition since the evidence does not back up the claim that blood group predicts a person’s personality.
Based on blood group theory, incidents of discrimination and racism have been reported. Blood type harassment or ‘bura-hara’ also exists. It is when children are discriminated against based on the blood group they possess. Similarly, job opportunities and relationships can also get strained due to this.
Personalities based on Blood Groups
There are four types of blood groups i.e. A, B, AB, and O. Each blood group is different from the other based on their antigens. Antigens refer to a molecule that is present on the surface of the red blood cells. These decide how well our immune system works. According to Japanese people, these antigens are a medical basis of why our personality differs from one another.
Personality based on Blood Group A
People with blood group A can be described as someone who likes to cooperate with others. Blood Type A personalities are also emotional and sensitive people who are quite passionate in their relationships. They are committed and loyal to their friends. Their priority is to maintain peace and harmony both internally and externally. This points to the idea that these people do not like to get into conflicts.

Personality based on Blood Group B

They dislike being ordered around by authority. So, this indicates that they like to follow their own rules. They invest their energy and put effort into making their work stand out.
