Scientology is an American cult started by a science fiction writer. It is not unlike MBTI which is also an American cult based not on science but fiction.
It is important to remember that America is the land of cults run as wealthy businesses. And MBTI is as American as apple pie.
Indeed MBTI is an American cult run as a business. In America MBTI is a registered business trademark. And if you in anyway use their business trademark, they will take you to Court and seek monetary damages.
The reason this site is not called MBTI Central is because the MBTI business threatened to take us to Court and claim monetary damages.
MBTI is not a benign personality test it is a threatening business cult, not unlike Scientology.
Scientology, for instance, has its bogus E-meter while MBTI has its bogus personality test.
And the purpose of the E-meter and the personality test is to distract your mind and put you in a trance where you are susceptible to suggestion.
