Myth: There are no two identical leaves in the world, and everyone's personality is different. So what determines personality? An article said: "Blood type determines personality, and personality plays a vital role in the success of a career. Experience shows that people with type O or type B blood are relatively stable and have affinity, which is an indispensable condition for senior sales talents. " Is it true that blood type determines personality in the article?

Let's talk about whether there is any correlation between personality and blood type.

True blood type personality theory

Japanese scholar Takeji Furukawa first put forward the theory of blood type and personality. According to his daily observation and investigation, he put forward in 1927 that "people have different temperaments because of their different blood types; The same blood type, the same temperament. " Although at that time, Takeji Furukawa's viewpoint caused quite a stir in the society, the theory of blood type personality did not cause an uproar in the psychological field. After World War II, the research on the relationship between blood type and personality in Japan has been further developed, and the representative figures are Masayoshi Suzuki and Nojiro. These researchers have different opinions, but they all correspond people's personality and blood type and divide different personality types.

In 1980s, the theory of blood type and personality was all the rage in China. After the 1990s, the theory of blood type personality appeared on the Internet in large numbers, with a very wide spread. But so far, researchers have not found any evidence to support the blood type personality theory.

How is the blood type classified?

As we all know, there are three blood types: ABO. So, what is the classification basis? Can it really be divided into three kinds of ABO?

First of all, the so-called ABO blood group actually refers to the type of antigenic determinant on human red blood cells. According to the different antigens on the surface of red blood cells, it can be divided into type A, type B, type AB and type O. In normal people's blood, there is an antigen on the surface of red blood cells, and there will also be corresponding antibodies in serum (this antibody will not bind to the antigen on the surface of red blood cells). Once antibodies find other antigens in blood, they will quickly combine with them, thus causing blood agglutination and life-threatening, which is why transfusion accidents may occur between different blood types. However, the expression of AB antigen in some people's blood is not obvious, so different AB subtypes will be formed.

But ABO blood group is not the only blood group system. Up to 20 16, 346 red blood cell antigens and 36 corresponding blood group systems have been found. Rh blood group is often mentioned, among which Rh negative blood group is not common in China, and another is Rh-null blood group. In the past 50 years, only 43 cases have been found in the world, which is a relatively rare blood type.

Does blood type really determine personality?

First of all, personality is a relatively stable psychological state of personality, which is mainly manifested in the attitude and behavior towards reality, which is the main difference between individuals and others. The formation of personality is mainly influenced by three main factors: heredity, growth and social environment, both from itself and from the external environment. According to psychological analysis, people's personalities are generally divided into four types: sanguine, depressive, choleric and mucinous. Because of the influence of genetic factors, some people are born with strong emotional expression ability and bloody personality, so genetic factors determine people's personality to some extent. So personality and blood type are not necessarily related.

Since the emergence of human beings, human blood types have been classified and evolved. With the change of living environment and the outbreak of diseases such as cholera and smallpox, their distribution is constantly changing. Blood type, like all kinds of creatures on the earth, has experienced cruel natural selection and evolution and change for hundreds of millions of years. It is by no means used to predict the fate and future for many people. Finally, it is an ignorant fallacy that blood type determines personality, not truth.
