Blood Type and Horoscope

 

Using blood type and horoscope to match personality is seemingly popular among female regardless of age and education background. For instance, one colleague of mine has PhD from Princeton University majoring Economics, but  her believing in horoscope  is almost close to “exuberant” level.  Her morning routines include to have a cup of Caffé  Mocha from Starbucks and to check daily  horoscope section on Financial Analytics. So to avoid her cranky mood we’d let her have both before daily briefing. 

However, I think that neither blood type nor horoscope has convincing scientific backing and useful application to qualify what believers have claimed. It is my own opinion that our personalities are most likely affected by environments we grew up with. Furthermore, personalities might not be chiseled on the stone as we may like to think. There are plenty evidences to show many people would modify their personalities during their life in order to adapt or respond to “ecosystem” they live.
