What Is the Blood Type Personality Theory?
The blood type personality theory, also known as ketsueki-gata, is the belief that a person's blood type determines their personality. Though this theory isn't scientifically backed, it's seen as a fun way to explore one's traits and characteristics in Japan, similar to the way people use astrology to explore their personalities in the U.S.[1] This quiz tells you what your blood type personality would be according to ketsueki-gata—here are the possible results and what they may reveal about you:
Type A
You're a responsible, considerate, and hardworking person. You're not a risk-taker or rule-breaker—you value honesty, and you do things by the book. At times, you can come across as a bit perfectionistic or uptight, but this is just because you care so much about doing a good job, and you're always pushing yourself to be the best you can be. Luckily, you know you're at your best when collaborating with others, so you don't go it alone. You're a true team player, and your kindness radiates!
Type B
You're a creative, independent person who's always seeking out passion and intensity in life. You feel most yourself when you're having exciting adventures and exploring new things, and you're also an outgoing social butterfly. You don't like strict rules or rigid schedules—you prefer a more laid-back approach to life. At times, you can come across as a bit impulsive or irresponsible, but this is just because you're such a free spirit. One thing's for certain—with traits like these, your life will never be boring!
Type AB
With your unique mix of both Type A and Type B traits, you're a complex and adaptable person who can thrive in just about any situation. At times, you may come across as a bit indecisive or hard to pin down, but this is just because you can see all sides of a situation, and you're able to adjust your approach to fit whatever environment you find yourself in. You're rational yet creative, caring yet composed, dependable yet flexible...long story short, you're the best of both worlds, and you can succeed at anything you set your mind to!
Type O
You're a confident, ambitious person who isn't afraid to take charge in life. You approach everything you do with determination, and no one can stop you when you set your mind to something. Because you're so strong-willed, you may come across as a bit arrogant or insensitive at times, but you don't mean to hurt other people's feelings—you've just got big goals, and you're won't stop until you achieve them. You also have an amazing set of instincts that help y you make the right calls in your journey toward your dreams. With traits like these, you're clearly a natural-born leader!
