I don't consider it marketing.
SO, in my opinion, there is a ton of rubbish with regard to so-called Appraisal Statistics. Absolute rubbish and nonsense perpetrated by some well known MAIs and others in the appraisal field who teach statistics for appraisers or voice their opinions in articles, books, podcasts and videos. -- It seems they take advantage of the fact that even the simplest statistics is beyond the reach of most appraisers, and they get very reckless in their statements, as they feel safe in what they consider is a knowledge level superior to most other appraisers.
Their day is coming to an end. Just about anyone can just take their statements, even articles and books to some Chat Box and get an objective and even detailed opinion as to their conceptual correctness and relevance. It is not just my opinion. It's the opinion of a massive computer system that has digested hundreds, or even thousands of relevant publications, that has itself been trained on multiple tests, and also has highly advanced reasoning and mathematics engines at its disposal.
The day of MAI charlatans comes to an end. You would think they realized that by now. But that is apparently not the case, these idiots stubbornly proceed a bit longer.
There is a group of these charlatans stemming from some oldies in the field. They all pat each other on the back and say they have done a good job. Well, "good" things don't last forever.
Be careful who you support. Think twice before giving a thumbs up --- because you may dirty yourself as a result. That applies to everyone. I made that mistake long ago, in using someone as reference in a presentation -- because I simply couldn't find any appraiser to quote as a reference and thought I needed one. I should have just foregone using the damned idiot. But, I thought I needed some kind of reference. That someone is still around and selling the same rubbish.
However, things are progressing very fast now, everything moves ahead. The charlatans need to be dumped. The sooner, the better.
The latest thing we need is MAIs who claim to understand AI and Statistics showing off what they think are strokes of genius on LinkedIn. Then I make a negative comment, which rarely makes it beyond their private eyes and next thing you know, their bright idea is pulled off LinkedIn, or whatever. Well, that's a good thing.
One could argue, that presenting fallacious interpretations and incorrect concepts is better than nothing. Well sure, if they don't mind criticism, I'd agree.
I am marketing, if anything, removal of incompetency. In appraisal, that is a big job. I am constantly moving forward to Valuation Engineering - and hoping for even more progress.
What is the purpose of all this? Well, it is what it is. You can make up your own mind. - I will keep doing the same thing in trying to improve valuation. Somewhere or another, what I actually do changes with time.
I draw a line between those who have some hope of progressing further and themselves improving things and those who are tied up in the past, supporting their status quo.
Here is a very good book to read. See if you can really understand the nuances:
Clayton, Aubrey. Bernoulli's Fallacy: Statistical Illogic and the Crisis of Modern Science (pp. 97-100). (Function). Kindle Edition.
Aubrey Clayton's writing on math, statistics, and probability has been featured in Boston Globe Ideas and internationally-renowned journals.
