Can Blood Type Determine Your Personality?
by: Natalie Josef

The history of the theory that blood type determines personality is actually a dark one. In 1900, Austrian scientist Karl Landsteiner discovered the four blood types. Like 19th-century scientists who used brain size (the larger the brain, the more advanced) to propagate theories of racial and gender superiority, many (white) scientists used the blood type theory as a way to push forward their own ideas of racial supremacy. Scientists from the west suggested (falsely, obviously) that Asians were inferior and sub-human since the vast majority of them—like animals—had type B blood. In 1927, Takeji Furukawa, a Japanese professor, introduced the theory to the Japanese public in a paper entitled, “The Study of Temperament Through Blood Type.” Even though he lacked the proper credentials and backed up nothing scientifically, the public embraced the idea of blood type as a determination of personality. The Japanese government even commissioned a study to determine if they could breed better soldiers. In the 1970s, a book by Masahiko Nomi revived the idea, which is still popular with the general Japanese public. In 2008, four books on the topic have hit Japan’s top ten bestseller lists.

What Your Blood Type Says About Your Personality

Type O
You are the social butterflies. Often popular and self-confident, you are very creative and always seem to be the center of attention. You make a good impression on people and you’re often quite attractive. Organized and determined, your stubbornness will help you reach your goals. You make good leaders. Lovewise, O is most compatible with O and AB. Common career choices: banker, politician, gambler, minister, investment broker, and pro athlete.

Type A
Type As may seem calm on the outside, but inside, you’re filled with anxiety and worry. You’re perfectionists and often shy and sensitive. Usually introverted, you’re stable and thoughtful. You make good listeners and are sensitive to color and your surroundings. You like to be fashionable and are up on the latest trends, but never flashy or gaudy. You like romantic settings and often shun reality for fantasy worlds. A is most compatible with A and AB in the love department. Common career choices: accountant, librarian, economist, writer, computer programmer, and gossip columnist.

Type B
You can be very goal-oriented and often complete the ambitious tasks set before you. Outgoing and very charming, you’re good at reading people and providing support. Though critical of appearance (but not your own), you aren’t picky and are unlikely to dwell over the little things. Type Bs are impulsive individualists who often create their own path in life. You are very strong and optimistic. B is most compatible with B and AB lovers. Common career choices: cook, hairdresser, military leader, talk show host, and journalist.

Type AB
Not surprisingly, ABs can be quite dualistic, possessing both A and B traits. You may be shy and outgoing, and hesitant and confident. You often stand out from others, don’t like labels, and are nice and easy going. You are logical and determined to do things correctly. Usually trustworthy, you like to help others. You often speak in a serious manner. Your patience, concentration, and intelligence are admirable. AB can find a soul mate with any other blood type. Common career choices: bartender, lawyer, teacher, sales representative, and social worker.

We all love to know things about ourselves and blood type is just another fun way to learn new traits and understand why we do certain things. You don’t have to believe in it to get something out of it—just have fun with it and take it with a grain of salt. My blood type is actually considered the worst in Japan; no one wants to work with ABs and most anime villains are that type. Thank God I live in America!

    I am type A and I find it quite accurate but MBTI is a more accurate test

    I have Type O blood, but would more fit the personality description for AB. More than that, since there are more in the population of Type O than any other blood type, it's hard for me to picture a balance within the scope of society on the basis of this.

    I have type O and that describes my personality to a tee! But I think for the overall population this is a huge generalization seeing as my dad and sister are both type O and the 3 of us are completely different.

    The description of my blood type does not fit my personality at all. Hmmmm.... makes me wonder if my blood is really my blood????

      Good Gawdess, Articulates! That brings up a question I have reason to worry about. I remember having a boyfriend in San Francisco, named (no joke) Mark, who was a vampire. Maybe he took more blood from me than I thought? Maybe when I passed out, somebody made a hideous exchange?

    I am B+ and my Daughter is AB.
    Love the career choices, I was a head chef for 11 years and ended up disliking it and falling back on my management degree and now I am a negotiator

    I'm both O Positive and HIV Positive, you might be on to something here..

    Hey, I am a type B+ and it sounds much like me. My brothers and I all took it from our mother and we are very much like that. I might be true. Just like we are not born under a particular star for no reason maybe our blood type can define our personalities as well and our career path too.
    It doesn’t have to work for everybody but it sure does for me.
  8. Jhangora
    I am an O+ and some points are correct. Thanx for the info.
  9. visualinked

    When I was living in Japan that was the first question anyone asked me 'What bloodtype are you?'. It was very weird...=)
  11. farangrakthai
    This is a Japanese thing, they sure believe in it.
    But I don't

    All these deterministic theories about human personality are just an evasion of responsibility. Our actions make us who we are.

    I've worked at The American Red Cross in blood collections for almost 12 years and I do find that a lot of simularities between certain blood types as far as personalities goes. I once heard that in China, that they put children in their classrooms according to their blood type.
  14. BetsyIckes
    I'm O+ So who is to say?
  15. spaceaye
    I recently discovered that I´m type O and many of these points are correct.
    1. BetsyIckes
      See what I mean! LOL

    This sounds like ... Astrology

    Every human gene interacts with at least one other one and they form the so called genetic networks. The variations in gene structure know as alleles (for example A, B and 0 are different alleles of the same gene) can change these interaction and from here the complete genetic network. If the blood group gene interacts during the embryonic development with other genes participating in nervous system formation it can actually influence the character of the people. I do not know though about serious articles dealing with this issue.
