Frequently asked
Is blood type personality real?
No. Decades of psychological studies have failed to find any reliable link between ABO blood type and personality traits. Ketsueki-gata is a Japanese cultural belief popularized in the 1970s — a fun social lens, not a scientific finding. Treat this quiz the way you’d treat a magazine horoscope.
What is ketsueki-gata?
Ketsueki-gata (血液型) literally means “blood type.” In Japan, the phrase carries a second meaning: the widespread pop belief that ABO blood type reveals personality. It shows up in dating apps, TV panel shows, morning-drama character bios, and small talk. Outside Japan the idea is barely known, which is exactly what makes it a fun cultural export.
Where did the idea come from?
The modern version was popularized by Masahiko Nomi’s 1971 book Understanding Compatibility from Blood Types, drawing on discredited pre-war research. It spread through the 1980s manga, magazines, and radio. Mainstream psychology reviews (in and outside Japan) have consistently found no meaningful correlation between ABO type and personality dimensions.
Should I use blood type to judge people?
No. Doing so has a name in Japan: bura-hara (“blood type harassment”), and it is widely criticized. Enjoy the quiz as a cultural artifact — never as a hiring, dating, or parenting rubric.
How does this quiz work?
You answer 10 everyday-life questions. Each option is tagged with one of the four stereotype profiles (A, B, O, AB) and adds a point to that type. Whichever type collects the most points is your result — with a small tie-break rule if two types match. Everything runs in your browser: your answers are not stored, sent, or logged anywhere.
