The blood type personality theory is pseudoscience that is similar to astrology and the Myers–Briggs Type Indicator. They can be relatable because they’re so vague. Like you said, it’s 60 percent accurate. What this means is that a person is likely to fit into any of the categories to some extent. I read all the categories and I fit into all of them to one extent or another.
What is fascinating about these kinds of categorizations is that humans are wired to want to be categorized. It makes us feel that we belong and gives us a sense of identity and a feeling of understanding ourselves. So what we do when we come across these categories is that we tend to want to believe they’re true, and instead of questioning the details, we dismiss the parts that don’t resonate with us.
Part of the problem is also that we tend to behave differently in different situations. For example, I can see myself as both cooperative and uncooperative. So it’s easy to fit into any category, because human personalities are complex and not reducible to a single binary statement.
@Seraph it was from the work of <a href="https://en.wikipedia.org/wiki/Masahiko_Nomi" title="Masahiko Nomi" style="color: rgb(11, 0, 128); background: none rgb(255, 255, 255); font-family: sans-serif; font-size: 14px;">Masahiko Nomi</a> in the 1970s. It was more of a pseudoscientif belief in Korea and Japan. It is not proven by scientific research but more on superstition.
Some of the traits are accurate for me. So when I came across this, I was interested to know if there is accuracy for everyone.
Interesting... and by whom was this study conducted, Florian?
By the way, it 100% opposites my personality. Is there any scientific explanation to it?
It looks like a horoscope.
