I should mention, the medication-prescription issue and the fecal matter don't stink thankfully rarely come up, and I think the debates that occurred on this forum of that nature were somewhat heightened because we don't see each other in person plus some trolls messing things up.
My dept. has some great psychologists working in it and no one's ever gave a dirty eye to the other. Same happened when I worked in a state hospital. If a psych didn't like the psych of the other dept, it was usually only because one of them was bad and the other was good, and the good one didn't like working with the bad one---and only because of that. Not because of a rivalry.
I was able to kick out a malingering patient threatening quite extensively that he was going to kill himself from the inpatient unit. The psychologist on my unit did a SIRS exam showing with 100% certainty that this guy was malingering giving me rock-solid footing in having the guy discharged. Thank God I had this guy working with me. Had I done a SIRS myself, they are tedious and his knowledge of the SIRS is better than mine.
