Why do people with AB blood easily get schizophrenia?

I am a Gemini! In fact, blood type is not very accurate in judging personality, but it is said that AB people have two sides. In addition, Gemini people also have two sides, so compared with other constellations, their emotions fluctuate. As for schizophrenia, not necessarily. Only when people are traumatized by a huge blow can they get schizophrenia. However, everyone has the ability to self-repair mental trauma, which does not mean that AB+ Gemini is very likely. The basic psychology of people who get it is very fragile!
