I just read these words “epistemic persistence!”  Had to look them up!  Last week’s blog talked about the power of words.  On discovering these new ones, I was gobsmacked (another cool word)!

These two words together concisely describe what has been bothering me about the appraisal function (and many other things we humans seem to concoct).  How could two words sum up the sickness, the malady which affects so much?  Close to me, it affects my chosen profession — appraisal.  And this malady affects everyone.

Anyone who lives in a house or an apartment is affected.  “Unaffordability” they call it.  So, it also affects anyone who cannot have a house, an apartment, a weatherproof box, a safe spot behind the bushes or a tent under a highway overpass.

I am in the richest large country in the world.  Incredible science.  Knowledge of human behavior.  Access to the benefits of ethical behavior (not just ethical rules)!  Good food and clean water.

So, why is there a problem?  Why is it harder for our children than it was for our parents?  Does this make sense?

I have found some of the cause.  Or rather, it gobsmacked me.

Epistemic persistence is simple, yet profound.  It means “The ability of knowledge-related objects, beliefs, or frames to remain stable or continue existing despite scientific changes, challenges or the passage of time.”

My prior perspective was expressed in the “five frictions” which hold back the ability of appraisal to advance to its potential today.  And potential beyond today.

The five frictions include appraisal:  practices, standards, education, regulation, and client expectation.

For our profession, these each in their current form, “continue to exist despite scientific changes, challenges, or the passage of time”. This is epistemic persistence!

We continue to exhort appraisers to carefully pick comparables, even where data and data science and economic theory and relevant statistics are available – and easier to use than “defending” judgment!

We continue to be taught that an appraiser must pick comps, then do a market analysis!  Our trainers tell us this.  Our education books tell us this.  Clients demand this (under threat of the “ROV”).  And state regulations require and enforce this.

Only USPAP gets it right.  Standard 1 says use all available, relevant data!  All.

So there you have it.  Four of our five frictions demonstrate and perpetuate our epistemic persistence.  It is why we are vulnerable to accusations of bias.  It is why we need a system (Reconsideration of Value) to compensate for what could have been done right in the first place.

Last week we mentioned the need to take personal and organizational inventory.  It is time.  Most all problems come from fear.  This can take the form of anger, ego, self-righteousness, or simply laziness and not caring.

Does anyone care?  Yes.  I know some who do.
