It pumps through your veins and arteries keeping every cell in your body alive, yet you rarely think about your blood. How often have you consider how it relates to your personality? Your blood type and personality may have more in common than you might think.

Much of our personality is determined by genetics. It makes sense that personality and blood type could be connected. Your blood type is also determined by your genetic heritage. In a cross-cultural study of blood antigens and personality traits, researchers found correlations between type and personality.

In another study of teenage boys and personality styles, blood type A was typically seen as more “tender-minded.” Meanwhile, types O, B, and AB came across as more “tough-minded.”

You may recall the book Eat Right for Your Type by James D’Adamo, which spoke to matching diet with your blood type. Donna Gates worked with the research of James D’Adamo for her book, The Body Ecology Diet. There are definite connections between blood type and health. For example, eight out of 10 children with autism have type A blood.

Japanese employers will ask the blood type of their job candidates because they feel strongly that personality is linked. In Japan, many people also consider this information when seeking out potential romantic partners. Marketers there use similar consideration for marketing specific products.

Personality of Blood Type O

Famous “Type O” People: Al Capone, Gerald Ford, Mikhail Gorbachev, John Gotti, Crystal Kay, Queen Elizabeth II, John Lennon, Paul Newman, Elvis Presley, Ronald Reagan.

The O in type O could stand for outgoing because that is a typical personality trait. These people tend to be go-getters who set high standards for themselves and achieve them.

The type O personality is usually a leader, has excellent intuition and can manage stress better than other blood types. These personalities demonstrate confidence, but can come off as insensitive to others.

O’s are most romantically compatible with other O’s or AB’s.

Personality of Blood Type A

Famous “Type A” People: George H. W. Bush, Ayumi Hamasaki, O.J. Simpson, Britney Spears, Alan Alda, Adolf Hitler, Lyndon B. Johnson, Richard Nixon, Jet Li, Maki Nomiya, Rick James.

The most research on personality and blood types comes from Japan, where 74% of the population have type A. A’s tend to have a more sensitive constitution than other types. Stress can weaken their immunity. Unfortunately, they tend to handle stress poorly.

Those with blood type A generally demonstrate more anxiety and less trust than other blood types. These personalities tend to follow intellectual pursuits in fields such as science, math and research. Since they lean toward introversion, they work best independently. At the same time, they are also good at cooperating with others.

Blood type A personalities can be passionate, but require trust to be established before they can be intimate with someone. They tend to be perfectionists who demonstrate patience.

A’s are most compatible with other A’s or with the blended personality of AB.

Personality of Blood Type B

Famous “Type B” People: Akira Kurosawa, Jack Nicholson, Luciano Pavarotti, Tom Selleck, Mia Farrow, Paul McCartney, Leonardo DiCaprio, Vince Young.

If you are a blood type B, your personality tends to be creative, introspective, empathetic, emotional and intelligent. At the same time, you can be self-focused and come across as selfish, but you tend to be the most caring of the blood types.

B’s generally balance the personalities attributed to both type O and type A. B’s are ambitious like O’s are, but they are also thoughtful like the A.

Health-wise, B’s are more likely to develop lupus, multiple sclerosis and chronic fatigue.

B’s are compatible with other B’s. They can also relate well to AB’s.

Personality of Blood Type AB

Famous “Type AB” People: John F. Kennedy, Marilyn Monroe, Mick Jagger, Thomas Edison, Bob Sapp, Miyavi, Jackie Chan, Ken Kitamura.

As you might imagine, people with a mixed type AB also have a mix of personality traits. AB types are trustworthy, but they can be both shy or outgoing depending on the situation.

AB’s can be charming, connected to their spirituality, relaxed, open to change and friendly. The AB blood type personality is very individualistic and prefers to be different from other people.

Romantically speaking, AB’s are compatible with any of the types, including other AB’s.
