I think somebody must be pretty intelligent to manipulate a psych test.
Let's just say the designers of the test aren't very smart to let be manipulate-able. So, go for it, as you really should get what you need from the system and maybe that's the best way. If you do want therapy, the T will probably feel it's good to work with someone who can think things through pretty well.
P.S. I've done it too. They really do seem to think we can't see what's going on.
