The constellation blood typeAnd the disposition relationship forever is the most popular topic of urban white-collar workers.Some scoffed, some revel in.For many white-collar workers, which couples out blood type may quarrel, who and who sign matches can be matched together, and so on gossip, is an essential part of every day dinner seasoning.

According to the description of a book is very popular in Japan [1] : type O people love life, attaches great importance to the power;Type A people attaches great importance to the outside world, is A perfectionist;Type B people behaviour, the interest is extensive;Type AB people engage, freedom is bold and unrestrained.If written in the book the relationship between different blood types corresponding to different character compared to the colleagues around, some people might exclaim, "too", also some people will complain that "no".Accurate or not, scientists might help you answer this question.

Although blood type and constellation often appear in the same page of newspapers, magazines, however, by contrast, blood type looks more scientific personality theory, even the horoscope for such articles as pseudoscience, may also agree that type of personality, and blood type and close relationship may serve to deepen the impression in the field of medicine.Blood types are classified on blood method [2], the basis of classification is to look at the surface of red blood cells can if there is a certain genetic material.In layman's terms, blood type is according to the material on the surface of the red blood cells of different methods for the classification of human blood, and the marking substance on the surface of the red blood cells for everyone is usually determined by genetics, nature, life remains the same.Since 1900, the Austrian scientist Karl Landsteiner discovered for the first time in his lab in Vienna since the ABO blood group, scientists have discovered, including Rh blood group, Lewis, blood type, etc, as many as hundreds of blood type system (i.e., different blood classification method).The blood group system, the nature is the best known ABO blood group system.Often people talk about is related to the character of the ABO blood group system.

First suggested ABOBlood type and personalityRelationship of the expedition, is a bamboo two [3].In 1927 he proposed "people find different blood type, have their own different temperament;The same blood type, has the temperament of the common "hypothesis.Duration between the two world wars, sino-japanese from 1895The war"The defeat, qing to a paper of shimonoseki" Taiwan was ceded to Japan has more than 30 years.The expedition hypothesis is put forward by the Japanese colonial rule in Taiwan.On the basis of the expedition [4], the theory of Taiwan in the crowdType O bloodProportion is as high as 41.2%, far higher than the Japanese people, and people with type O blood "bold, aggressive, like to command others, confident, strong, positive and enterprising", and more aggressive type O blood.Living in the northeast of Japan, by contrast, ethnic minorities, according to Mr In 23.8% of those with type O blood, and according to Mr Race than Taiwanese more moderate and obedient.The expedition to explain why the Taiwanese to constant resistance to Japanese rule.Accordingly, he also suggested that to the authorities promote consanguineous marriages between Taiwanese to reduce the proportion of Taiwan people with type O blood.

From the expedition proposed his theory can be seen how ridiculous it is.These bizarre research is not uncommon in the fascist countries under the rule of [5], the Nazi German scientists have made investigation, type of different ethnic differences found that the blood type distribution of different ethnic groups, and thus makes more noble "Germanic blood" absurd conclusions.Attempt to use blood to prove that the crazy experiment of racial superiority finally come to an end after world war ii, the relationship between blood type and personality began to a pure science subject came to the attention of scientists.

To be clear, however, blood type and character of the relationship is not so easy.A different blood type can distinguish easily through blood tests, different personality and how to distinguish?

Personality is consistent and stable psychological characteristics, thinking and behavior.Want to use the way science is it is not easy to quantify the characteristics of these is subjective, scientists are the most commonly used method is to all kinds of questionnaire, through the results of the questionnaire to analyze the subjects' personality.The questionnaire made by professional psychology or psychiatrist, and after repeated calibration, after revision, can more objectively reflect the characteristics of the subjects' personality.Commonly used questionnaire has multiple personality test of Minnesota (MMPI), eysenck personality test (EPQ), the cartel of 16 personality factor questionnaire (16 pf), a vector field of guildford (Y - G) personality test and so on.The results of these tests are usually one's character can be divided into different Angle analysis, participants get high score in a certain way or low grade evaluation, representing the opposite character traits.For example 16 pf tests a person's character can be divided into 16 angles (referred to as the "dimension"), in one of the "N" sophisticated "dimension had lower scores on a more honest, forthright and naive, and the most high score is very smart and capable, very sophisticated;In the "H: dare to" low scores on the dimensions of timid retreat, lack of confidence, dare to adventure, have won high marks are few scruples.By means of the subjects in the history of the "dimension", one by one analysis, researchers can be roughly draw the outline of the whole picture of their character.
