Helen Fischer's work on personality types may hold some value that various hormones cause personality traits. Myers Briggs imho is just messed up thing no better than horoscopes.
It used to be used at a large company that I worked for. The preferred types were RED and BLUE around 2010. GREEN AND YELLOW I remember were overlooked for promotions. Everyone was trying to be the biggest idiot in the room to prove they were RED person. It propogated bullying and prevented good teamwork. Credit Stealing was legitimized with preference for RED. If Helen Fischer is correct and RED people are the closest to testesterone heavy people, the RED people have the shortest neural circuits.
