Well, you have several "points", but you haven't supplied any substantive support in the form of logical arguments; just several assertions without any basis. And the phrase "think so poorly of your peers" implies something that is subjective judgement on your part. I would say, that other appraisers are locked into a system that was handed to them and there are an insufficient number of intelligent leaders in the appraisal world to set things right.
Much of the problem was the mentorship requirements for trainees. That itself, preselected lower IQ and docile people into the profession who were willing to work at substandard wages for a number years and do what they were told. Yes, some trainees were smart college graduates who went to work for MAIs for a number of years, but eventually discovered the system for career advancement was extremely defective. Leaders in the profession, and I could name names, would tell trainees that they simply had to "pay their dues" to get to the top, i.e. attain MAI certification. Roadblocks were placed here and there that thwarted their progress. The carrot stick so visible at the beginning of their career disappeared slowly but surely. Would an MAI in an office doing reasonable amount of business on the backs of maybe 5 college graduate trainees were smarter than him, actually take the final step to get them their MAI, or would they be thrashed around unendlessly in clerical work and research at ultra-low pay until they quit?
The Appraisal Profession was architected to its modern day form, through both intention and incompetence. The incompetence in Appraisal is truly systemic and will be hard to correct, should there ever be a serious effort. .... Because there is no one around in the profession competent enough to rearchitect and rebuild it. Stupidity breeds stupidity and that is precisely where the profession is at.
Yes, there are a few around who could do something, but not enough to reach the required threshold to make things happen.
The profession will stagnate, and probably die. But there is some hope it may turn around in another 30 years or so.
