Blood Type Personalities: Science or Social Trend?

If you visit Japan or South Korea, asking "What's your blood type?" is like asking "What's your Zodiac sign?". This is the theory of Ketsuekigata.

The Stereotypes

• Type A: Organized, perfectionist, sensitive.
• Type B: Creative, passionate, independent.
• Type O: Confident, ambitious, natural leaders.
• Type AB: Rational, adaptable, mysterious.

The Science

Is there any truth to it? No. Modern medicine finds no correlation between red blood cell antigens and personality traits. Your behavior is shaped by genetics and environment, not your ABO group.

But it's fun to read! Try not to judge your date based on their blood type (unless you need a kidney!).
