How Not to Get Sued

I have read many places, including here, how medical doctor's getting sued has no correlation to how effective they are. It has to do with their people skills, specifically how long they sit with their patients and how quickly they apologize. I wonder if it is the same for counselors? Many of my professors have said that if you do become a full time therapist you will eventually get sued or at least deposed. But I am curious if the counselor's who aren't sued as often are the ones who treat their clients kinder? Counselors are supposed to be good at people skills, but I have met a few who are arrogant, unapproachable and harsh. I would love to see a study about this, because being sued does not sound fun to me
