Howdy larc,
Interestingly enough, my prof. said basically the same thing you have said. Psych. tests are tools. and Different tests tend to point to different aspects of the individual.
Ted Bundy, for instance. A test to try and determine his mental capabilities would probably show he was quite intelligent. From what I've read about him.....he was.
Now a test to show a propensity towards violence, towards hatred of women, towards aggression, towards the other dozen things he had going violently for him......might have shown up these things. However, being highly intelligent....he may have tricked the tests.
Afterall, the tests are subjective - and I've not read where any professional thinks the tests are foolproof. Just guides - or tools, as you've said.
Interestingly, IQ tests used to be given to immigrants while still on Ellis Island in the early decades of this century. Not so amazingly, many didn't do well. Being foreign, little English, totally different background......many were labeled because of these things, which has nothing to do with the innate intelligence.
Btw, I would assume that you're familiar with the BITCH test? We studied about that one too
Always enjoy your posts.
