Sometimes people try to diagnose personality traits based on blood type.
Here are some common “blood type clichés” that supposedly reveal one’s true nature, divided into the four blood types.
The content describes various types—like Type A, known for attentive consideration, and Type B, who tends to prefer acting alone.

In this “Scariest-When-They-Snap Blood Type Ranking,” adorable cats present the traits of how each blood type loses their temper, all to a rocking heavy metal beat!

A psychology test that reveals your hidden blood type

You might be thinking, “What do you mean by ‘real’ blood type?” or “You can find out your blood type with a test!” Here, the ‘real blood type’ refers to the one that’s closest to the popular theories about what each blood type is like.
Some people will match the typical traits of their actual blood type, while others won’t feel it fits.
If you’re in the latter group, the type with the most traits that apply to you is your ‘real blood type.’ Compare general perceptions of each blood type with your own case, and try it out casually!
Personality diagnosis based on blood type

This is a test that diagnoses the basic personality traits of blood types A, B, O, and AB, along with the true nature behind them.
For example: “Type A is meticulous, but in reality they’re only meticulous about the parts where it matters to them, and they’re sloppy about the rest.” It’s a seemingly contradictory observation, yet it oddly rings true, doesn’t it? Even putting blood types aside, when you look back on your own lifestyle, you may notice some behavior that’s a bit inconsistent.
Let this be a good opportunity to reflect on your daily habits!
A psychological test to find out your real blood type

Check your blood type objectively! In this quiz, you’ll find out which blood type you match when mapped to the common images of each type.
Questions like “What’s your biggest flaw?”, “What are your traits?”, and “What’s your favorite color?” are all quick and easy to answer.
To get realistic results, it’s important to answer intuitively! Did the result match your actual blood type? Since personality differences by blood type haven’t been scientifically proven, it’s only natural if they don’t align! Why not enjoy the contrast between general stereotypes and your real blood type?
Behavior during commuting to work or school, as understood by blood type

Even the little “commuter/student life clichés” supposedly differ by blood type! For example, Type A folks, even if they forget their commuter pass, casually breeze through with a spare ticket, and on the train they pretend to look at their phone while actually thinking hard about work or studies.
In contrast, Type O people, when they forget their pass, just buy a ticket for the day, keep forgetting it for about a week and repeat the same thing, and on the train they struggle to hold back laughter at a funny message from a friend.
It’s an extreme stereotype, but many of you probably kind of get it, right? If you use it as a reference, it might help you look at yourself more objectively!
