Get to Know the Personality of People from Their Blood Type Japanese Style Lifestyle – 1 hour ago

Jakarta, CNBC Indonesia – The Japanese have a personality concept based on the so-called blood group ketsueki-gata. In Sakura Country, blood type has a great influence on one’s life, work, and even love.

Ketsueki-gata considered pseudoscience, a thought that appears to be based on scientific principles but is not actually rooted in facts. Although there is no concrete evidence that blood type influences personality, this belief is widespread in Japan and other Asian countries.

History of Ketsueki-gata

To quote Very Well Mindin 1930, the Japanese professor Tokeji Furukawa published a report in Journal of Social Psychology entitled “A Study of Temperament and Blood-Groups.” In this paper, he argues that establishing a link between personality and blood type could be a useful basis for the study of temperament.

He compared these efforts to the classification of temperaments by the ancient Greek physician Hipporcrates as follows: optimistic, apathetic, irritable, and melancholic.

According to Furukawa, blood types A, B, O, and AB each have a unique influence on personality. Medically, blood types differ from one another because of their antigens, which are molecules on the surface of red blood cells that trigger the immune system to produce antibodies.

In his paper, he included detailed charts to suggest that blood type is related to temperament, but his research was criticized for relying too heavily on questionnaires and providing no empirical evidence.

Other researchers began challenging Furukawa’s claims about blood type personality just six years after he published his report.

Even so, concept ketsueki-gata never went away, along with the many books on blood personality types that hit the market in the 1970s. The study of ketsueki-gata continues into the 21st century around the world, including Australia, Taiwan and the United States.

Blood type and personality according to the concept of Ketsueki-gata

Followers of Ketsueki-gata argue that each blood type has different personality traits.

The following is an analysis of a person’s personality according to blood type which is said to be broken down based on temperament:

1. People with blood type A are associated with positive traits such as creativity, intelligence, and teamwork, while their negative traits are stubbornness and tension. People with type A blood are reported to be more common in Japan than people with other blood types.
2. People with blood type B exhibit strong, passionate, empathetic, and assertive personalities, but they are also associated with selfishness and erratic behavior. People with this blood type are said to clash with those with blood type A.
3. People with blood type AB are generally very rational and adaptable, but their weaknesses are indecision, criticality, and forgetfulness. This blood type is largely seen as sharing the characteristics of both type A and type B individuals. As this blood type is rare, people who have it are highly regarded in Japan.
4. Type O blood is associated with characteristics of being confident, persistent, and full of intuition, but they are also seen as selfish and unstable. They are said to be seen as selfish especially in individuals with blood type A.

Blood group and disease

Meanwhile, in America, blood type has not been associated with personality, but rather with certain diseases.

For example, blood type A individuals are known to have an increased risk of stomach cancer and heart disease; People with type B also have an increased risk of heart disease and ovarian cancer.

People with type AB blood have an increased risk of heart disease and pregnant women develop preeclampsia; and type O individuals are more likely to get boils, attract mosquitoes, and experience Achilles tendon injuries
