There is no Church of Myers--Briggs, and no secrets. Everything is open.
There are charlatans in any field, and they will use anything. They all use money, but using money does not make you a charlatan. That corporate HR departments hire charlatans only demonstrates that HR departments will hire anybody willing to give the HR director a kickback.

Very secretive, offered a free personality test to lure you into lots of paid courses. They were selling courses to an astonishing percentage of large corporations.
