Yes, they had no 'qualifications.' The thing is, many psychometrics created by 'experts' are probably bullshit too: (Stanford-Binet, Rorschack). Qualified psychometricians can kiss my ass.
As already mentioned, it wasn't 'plagairized' (I can only assume you're going for shock value)
Jung wasn't a collaborator in WWII. He was probably antisemetic (history of some of his comments), but he protected jewish psychologists, and when he fled to america he worked for the government by psychoanalyzing top nazi officials.
