Blood type personality theory - Wikipedia
There is a lot of information available online about perceived connections between blood types and personalities, but there is no scientific support See full . The results of Chi tests showed that, there was a statistically insignificant difference between Blood group and Personality (P>) so there is no relationship. Morning television shows, newspapers and magazines often publish blood type horoscopes and discuss relationship compatibility.
The Department of Home Science relationship between achievements, intelligence, study habits and personality characteristics are the point University of Calcutta, Kolkata of attraction in many studies. In the present study, the association between blood groups and personality West Bengal, India. The study was conducted on respondents, among them 50 were male and 50 were females. It stems from us as an individual. It predicts our behavior over a wide range of situation.
It does not alter dramatically over time. It distinguishes us in meaningful ways from others. Personality is that pattern of characteristic thoughts, feelings, and behaviors that distinguishes one person. Although he was a behaviorist who considered learned habits of great importance, he considers personality differences as growing out of our genetic inheritance. He is, therefore, primarily interested in what is usually called temperament.

Hall and Linz, Temperament is that aspect of our personalities that is genetically based, inborn, there from birth or even before. That does not mean that a temperament theory says we don't also have aspects of our personality that are learned, it's just that Eysenck focused on "nature," and left "nurture" to other theorists. Hall and Linz, Eysenck initially conceptualized personality as two, biologically-based categories of temperament.
Traits making up the type concept of a Neuroticism. Eysenck and Eysenck,pp. A subsequent univariate analysis their red cells clumped when mixed with separated sera from showed a significant difference in the mean scores for people. A fourth group AB was soon found. Blood of group A contains antibodies to antigen B; personality characteristics are confirmedin many studies.
It is group B blood contains anti-A antibodies or iso-agglutinins; assumed that blood groups have genetic properties and group AB has neither.

In the present study, A review of previous studies suggests that compared to those the association between type A personality with ABO blood with other blood types, blood Type B individuals would be groups were examined. The results of one AB individuals would be higher on conscientiousness. A main way ANOVA and post hoc LSD tests showed that, there was a effect for gender on neuroticism and an interaction effect for statistically significant difference between O blood group than gender and blood Type B on neuroticism were also predicted.
MANOVA results showed that the Mean of neuroticism in blood type O and blood type B had the combined dependent variables were not significantly affected highest Mean by blood type, nor by gender, nor were there any interaction of extraversion in blood type A and blood type B had the effects. No relationship between blood type and personality is highest In Japan extensive research on blood type and personality began more than 60 years ago.
Blood type can be a valuable clue for understanding your own uniqueness. Today, it is even more common to hear the Japanese ask your blood type than it is for Americans to ask your astrological sign. To most Japanese both biology and genetics have a role in determining personality. I lived there from the ages of 12 to During my years of travel and study in Japan, I had an opportunity to learn first-hand the ways that the Japanese used blood types and it immediately caught my attention -- especially because several years earlier I had also become fascinated with the work of Dr James D'Adamo.
His theory focused on how blood type could indicate the foods and lifestyle choices most compatible for you. One man's food is another man's poison. After meeting Dr James D'Adamo and reading his book, I began to question everyone about their blood type in an attempt to verify if blood type diet indeed provided clues to our individual uniqueness.
Twenty six years later, I am certain it does have merit and is worth our attention. In fact, when I began working with children with autism, I quickly saw that 8 out of 10 of them are blood type "A". An "A" myself, this told me a lot about the little bodies they were in and what their special needs were. Please reflect on this theory yourself and see if you don't agree.
While there is not a lot of "hard science" to date on blood type, it makes a lot of "common sense" to look further into this theory.
Blood carries the nutrients of foods into our cells and clearly not all blood is exactly the same. James D'Adamo's theories were based on patient observation, his son Peter D'Adamo has tried to use a more scientific approach on the activity of lectins proteins found in food.
Peter found that eating the wrong lectins for your blood type could cause weight gain, early aging and immune problems. Blood Type and Personality There are four blood types: O, A, AB and B, with blood type A being the most common where so much research on blood types have been focused -- in Japan. I find it interesting that the Japanese diet very much favors those with blood type A.
Fish is an important protein for B's and the Japanese consume more fish that any country in the world.
Lamban important protein for B's, is not available there. Here are some examples of blood type and personality, based on James and Peter D'Adamo's work: These studies are not yet fully confirmed, except that the ABO antigens are expressed in early embryos. Quite a few academic researchers[ who? Therefore, the blood type explained only 0. This result suggests that blood type explained very little of people's personalities. Nawata came to the conclusion that there is actually no relevance of blood type for personality.
Controversial statistically significant data[ edit ] However, some academic researchers have shown several statistically significant data in Japan and Korea. Akira Sakamoto and Kenji Yamazaki, Japanese social psychologists, analyzed 32, samples of annual opinion polls from through Cosy Muto and Masahiro Nagashima et al.
Nagasaki University conducted a supplementary survey of Yamazaki and Sakamoto in In the s, difference due to blood types was stabilized and variances became smaller.
Then in the s, difference was definitely statistically significant, too.
However, the effect magnitude was extremely small, despite 'significance' in the statistical sense. Another Japanese social psychologist, Shigeyuki Yamaoka Shotoku Universityannounced results of his questionnaires, which were conducted in 1, subjects  and 1, subjects In both cases, the subjects were university students, and only subjects with enough knowledge of and belief in the "blood-type diagnosis" showed meaningful differences.
He concluded that these differences must be the influence of mass mediaespecially TV programs.

Yamaoka later examined 6, samples from through in total and found the same result. In Japan, penetration rate of blood-typical personality traits were investigated. Yoriko Watanabe, a Japanese psychologist then Hokkaido Universitychose "well-known" traits and found most traits were known to no more than half of Japanese subjects were university students.
However, Kanazawa was not able to discover any association with blood-type differences and penetration rates.
