What are the different blood types?

There are four primary blood type groups: A, B, AB, and O. Each of which can be categorized as RhD positive or RhD negative, making a total of 8 blood types. However, in gauging blood type personality traits, you will only have to determine your blood type among the primary blood groups.

Why do Koreans believe that blood type can determine a person’s personality?

Associating one’s blood type with a person’s personality has been a part of Korean culture for around a century now. The Western world looks at different horoscopes to examine blood type compatibility with each other.

But in Korea, they may deem someone’s likability or potential as a romantic partner based on their blood type. Koreans even believe that a specific blood type can give important information on someone’s health status.

How the Blood Type Personality Theory began

The history of how one’s blood type can determine personality, health status, and more is quite bleak. It was initially incepted by Nazi Germany, where studies were conducted by analyzing blood type distribution. From here, a Japanese scholar picked up the framing and developed the theory of a link between personality and blood type.

It caught wind in Japan, although not so much within actual medical circles. From there, it spread to other countries in Asia, notably South Korea and Taiwan.

In South Korea, the idea of blood type determining your personality theory was popular in the early 2000s. During this time, it became mainstream to feature these theories in TV programs and films and even in many pop songs.

The Different Korean blood type personalities

Now it’s time to go over each blood type and explain what personality is assumed from each one. This includes their best and worst traits and even the worst blood type compatibility.

Blood Type A Personality

This blood type is typically seen as more conservative and introverted compared to other blood types. They’re expected to be quite considerate of others and are admirably punctual and patient.

Korean Blood Type Personality - All about this theory (2) Best traits

Some of their best traits are how loyal and creative they are. They do not trust easily, but once they do, you can rest assured they are loyal to you at a die-hard level.

Because those with blood type A are often perfectionists, they will absolutely go the extra mile to make sure everything has been done correctly and with care. They are valued for their trustworthiness as well as for how responsible and hardworking they often are.

Negative traits

On the flip side, they’re also assumed to be quite sensitive and lacking in courage. Trusting others or expressing various emotions also doesn’t come easy to them. With the amount of sensitivity they possess, it becomes easy for them to take things personally and, thus, tend to get hurt more easily.

You may also find a blood type A personality to be obsessive, secretive, and overall quite closed off. They may also be, unfortunately, quite self-conscious. They even lean towards having OCD, making them worry about unnecessary things sometimes.

Korean Blood Type Personality - All about this theory (3)

Positive traits

They want to get the best out of their lives and pursue their passions. They are highly curious, to the point where they may end up making numerous impulsive decisions. Some of their best traits are their sense of individualism and optimism, along with their animal-loving personality.

Blood type B people are incredibly honest and caring. Thanks to their outgoing, social butterfly personality, they also have an easy time making friends. Their honesty sometimes leads them into trouble, as they are not scared of bluntly speaking out in any situation, while others may wish for harmony and discreet behavior instead.

Negative traits

Unfortunately, others may see a blood type B person as someone who is self-centered and is considered shallow. And if some person or matter isn’t a passion, they may not move a muscle for it.

Additional bad traits of a blood type B person are their impatience and recklessness, on top of which they may also be quite moody and hold a high sense of pride. They may also be quite forgetful, especially over things that don’t align with their passions. Not everyone can handle their free and wild-spirited nature.

Unique trait

And as a fun tidbit, blood type B people typically have strong immune systems.

Positive traits

Although they seem largely unpredictable, they are quite rational and practical and have great self-control.

Much like blood type A, they also like to be meticulous with their work. Overall, they have a positive outlook on life.

Negative traits

On the more negative side, the type AB blood people only like to do things that serve them personally. They likewise tend to stay away from situations that offer any type of complexity or drama.

They like their own company a lot and have characteristics similar to being shy and aloof – which to others may show as coldness.
