What is your Blood Type (혈액형)?

“Who would’ve thought that blood type could be used to infer a person’s personality?”


The blood type personality theory is pseudoscience, but it is an intriguing conversation topic in South Korea. It also remains a popular way to perceive a person’s personality.

When getting to know someone, if “What’s your sign?” is a common question asked in the West, “What’s your blood type?” is a common question asked in South Korea. Despite the lack of scientific evidence, similar to how people regard horoscope in the West, Koreans believe that a person’s blood type can predict his/her personality.

F(x)'s "NU ABO"

The theory is a cultural belief which emerged in 1990s. It became prominent in 2000s after the release of pop songs like Kim Hyun Jung’s “Type B Men” and f(x)’s “NU ABO”, and films like “My Boyfriend is Type B” which propagated the belief.

While most Koreans may ask about your blood type without explicit intentions, some might subconsciously gauge your personality based on the theory. In extreme cases, some might apply the theory to determine your likability and even, compatibility with them.
