Constellation of platelets _ What constellation is platelets?

Personality refers to a person's fixed attitude and habitual behavior towards real life. A person's personality is acquired, and it will be influenced by various experiences and specific environments in the process of growing up.

Blood type refers to the blood component composed of red blood cells and platelets, which is a kind of antigen on its surface. In life, people usually refer to ABO blood group system, which is also the most well known.

Blood type is congenital, inherited from parents, but personality is acquired. Scientists have been making unremitting research on the relationship between them. This is also a long-debated topic in the field of psychology-part of the congenital and acquired dispute.

Nowadays, people know that blood type can't determine a person's personality, and personal personality is determined by social environment.

But before that, in order to prove their relationship, people have gone through a long process of exploration.

The Origin of Blood Type Personality Theory Takeji Furukawa of Tokyo University investigated 1245 subjects, and published the article "Research on Blood Type and Personality" in the magazine 1927, which is the origin of blood type personality theory.

The main viewpoints of blood type personality theory are as follows: the advantage of type A is creativity and rationality, and the disadvantage is excess; Type B has the advantages of being active and doer, but its disadvantages are selfishness and irresponsibility. O-type has the advantages of being sociable and optimistic, while its disadvantages are conceit and rudeness; The advantages of AB type are coldness, restraint and rationality, while the disadvantages are indecision and love of criticism.

Related research psychologists Carter and others once published a paper entitled "Blood Type and Personality Traits" in the American Journal of Human Genetics to introduce their experiments.

They tested 568 subjects with Cattell's 16 personality factor questionnaire, and found that one of them-docility-was significantly related to ABO blood group: type B was more docile than types A and O.

However, this result is contrary to the viewpoint of blood type personality theory.

Swan et al. investigated 547 children with the same psychological test. He found that another index was significantly related to ABO blood group-relaxation-tension: type O was more nervous than types A and B, and type AB was the most nervous.

They surveyed 534 villagers in villages around Oxford. The results showed that the IQ of type A2 was related to ABO blood group, and the average IQ of type A2 was slightly higher than that of type O, while the latter was higher than that of type A 1.

Later, some researchers confirmed that this remarkable difference was due to statistical illusion.

Some researchers published a paper in the journal Nature. They studied the blood types of blood donors in British blood transfusion centers, combined with their socio-economic status, and finally came to the conclusion that type A is more likely (about 15%) to appear in the first and second social classes (the British government divides social occupations into five classes) and engage in creative work.

In addition, many scientists have studied the relationship between blood type and personality, blood type and personality, and blood type and intelligence, and reached different conclusions.

Among them, many experiments were criticized by the follow-up research, and they ignored the influence of some extra variables on the results during the experiment. These extra variables confuse researchers' judgment and make them think that personality differences are really caused by changes in independent variables.

For example, the choice of subjects and the characteristics of subjects themselves are ignored by many researchers, which leads to the low validity of the experiment, which is related to the political and social instability in the last century.

With the deepening of our understanding of blood type and personality, modern psychology generally believes that blood type and personality have no correlation and there is no causal relationship.

Psychology is a science, and one of its characteristics is falsifiability. It is precisely because of this characteristic of psychology that many experimental conclusions can be overturned and people can further understand the truth.

Little knowledge: What constellation are you? I don't know when people began to pay attention to their horoscopes.

Constellations are so gorgeous. From the perspective of the universe, constellations are wrapped in mysterious veil, blooming with radiant light and gestating the possibility of life.

Influenced by astrology and fairy tales, people began to associate constellations with people's personality.

For example, Aries is impulsive, adventurous and thoughtful; Taurus is realistic, loves money and looks noble. Gemini is smart, smart, hot and popular; Cancer is sensitive, sensitive and considerate; The lion is realistic, domineering and controlling; Virgo is perfect and demanding; Libra is always hesitant and elegant. ...

In fact, all this is unscientific and can only be used for people's entertainment, and can't be taken seriously.

Barnum effect points out that people often think that if a general description of personality can reveal their own characteristics very accurately, then when others use some general, vague and broad adjectives to describe a person again, they are often easily accepted by the other party, and they are convinced that what they say in the description is themselves.

In other words, because people want to believe, they convince themselves that these things are true and even collect evidence to prove their authenticity.
