"But, you do have whatever side of the bed the judge woke up on decisions."

Then you have appeals. And you don't have closed room meetings with only one other person who can label you and have others believe the label without question.

I am not saying lawyers/plumbers etc don't have to be skilled at arguments or plumbing nor that law or plumbing is free from human error. Or take on only cases they have experience in handling.
I am saying no one tries to sell just one sort of argument and often, in my experience, therapists/clients do.
I will never ever do cbt - there are people who will only do cbt - in law you can't say I have a child custody problem but I will only bring that problem to tax court - that was my point.
