I think that the faking of psychological problems in itself would be indicative of a need for psychological treatment, anyway. It's kind of like they're just making their issues more visible - whether consciously or not.
Very true, I agree --but what I wonder is how is a therapist going to know that this is going on in the first place, in order to best treat the underlying issues? Or would therapists figure it out on their own, and go on to treat the underlying problems unbeknownst to the patient?
