1
Stubborn Type As know exactly what they want and how they want it, so it can be difficult for them whenever someone else wants something different. They may be quick to shut down others’ ideas if they don’t align with what the type A thinks is best, and they can have a hard time admitting when they’re wrong.
- It’s important for type As to remember to look at things objectively. Just because an idea came from someone else doesn’t automatically mean it’s bad. They should consider what’s best for the whole group or project rather than what’s best for themselves.
2
Uptight and obsessive Type As are rule followers. They place a lot of value on etiquette and social standards, and they often have an individual moral code that they strictly follow. On the rare occasion they do break the rules, things usually end poorly, often as a self-fulfilling prophecy.^{[5]XResearch source}
- Type As should try letting their hair down once in a while. It’s okay to enjoy things without worrying about someone else’s opinion.
3
Overly sensitive People with type A blood often take things too personally, which leads to them feeling hurt quite frequently. Because they try so hard to make sure everything goes smoothly, any critique on the situation can feel like a personal attack because they put so much of themselves into everything they do.^{[6]XResearch source}
- Type As need to understand that constructive criticism isn’t an insult; it’s valuable feedback that allows them to better themselves or their project. There’s always room for improvement, and that isn’t a bad thing!
4
Easily stressed Because people with type A blood tend to be perfectionists, they often panic when even one little thing goes wrong. They may take on additional tasks to try to correct the situation, which often leads to them becoming even more stressed and overwhelmed.
- Many type As benefit from allowing someone else to take charge and stepping away for a bit. They need to understand that some things are out of their hands and it’s okay to take a breather now and then.
Reserved and shy, Type As often seem secretive and closed-off to others. They tend to keep to themselves because they struggle with self-consciousness and have difficulty trusting others.^{[7]XResearch source}

Blood Type A Compatibility

Type As are most compatible with other type As and ABs. Since type As are often perfectionists and strict rule-followers, it makes sense that they’d look for someone who also has those traits—which often means they end up with another type A. Type ABs are adaptable and possess traits of both types A and B, so they may also have some of the characteristics a type A looks for in a partner.^{[8]XResearch source}
- Some also say type As are compatible with type Os because Os are confident leaders who can help break the type A out of their shell.
- Type As are least compatible with type Bs because Bs are outgoing, impulsive, and can be impatient and reckless.
- Type As get to know people slowly, so they’re not looking for someone who wants to rush into a relationship.

Blood Type Theory Overview

Download Article

East Asian cultures believe blood type influences your personality. Also known as ketsueki-gata, this theory is prominent in countries like Japan and South Korea, and it has begun gaining interest in Western countries like the United States. Someone might ask “What’s your blood type?” the same way we ask “What’s your zodiac sign?”^{[15]XResearch source}
- Like zodiac signs, your blood type is believed to affect your personality strengths and weaknesses, how you behave, who you’re compatible with, and what careers you’re most suited for.
- While this theory is a pseudoscience and there is no scientific evidence to support it, it’s mostly considered a fun way to get to know someone and break the ice.
- The 4 blood types are A, B, AB, and O. Different antigens, or molecules on the surface of red blood cells, determine your blood type.^{[16]XTrustworthy SourceRed Cross Blood Donation ServicesWebsite run by the Red Cross Organization providing information about how and where to donate blood safelyGo to source}
- Whether your blood type is positive or negative does not seem to affect your personality. So someone with A+ blood and someone with A- blood would have similar traits, for example.
- The blood type personality theory originated in 1930 when Japanese professor Tokeji Furukawa published a report called “A Study of Temperament and Blood-Groups” in the Journal of Social Psychology, in which he argued that establishing a link between blood type and personality might aid in the study of temperament.^{[17]XResearch source}
