Just curious, Bert. Who is we? I was under the impression everyone except you are morons? Let me know if I'm typing too slow - I'll try to speed up.
The traditional classification in psychometrics is:
Idiot: IQ 0-25
Imbecile: IQ 26-50
Moron: IQ 51-70
But these terms are no longer used in contemporary psychology or psychometrics because they carry an awful stigma. Instead, the terms "intellectual disability" or "developmental disability" are used. Yeah, they just changed the names to get rid of the stigma, to hide the problem as best possible. And who knows - maybe someday they will figure out a cure. Could be!
So, where does that leave our precious terms "idiot", "imbecile," and "moron"? They are used very loosely in speech. In reality, this means that whatever group of people someone is using as a reference for "average" intelligence, a so-called idiot, imbecile, or moron would be someone who falls considerably below this standard of average.
So we can add to the above classifications:
Below Average Intelligence: 70-84
Average Intelligence: 85-115
Above Average Intelligence: 116-129
Superior or Gifted: 130 and above.
At the University level, "Gifted" really means, I tend to think, having an IQ over 150 -- but it, again, really depends on the milieu, your social environment.
So, if your group, or social milieu, is the set of students going to Stanford University, where 80% of the students have IQs over 130, then I suppose a "moron" would be someone with an IQ of 120 or lower. In that context, that would be the vast majority of appraisers. Then that 20% at Stanford - they are probably ace swimmers, football players or whatever .... or have very good connections.
And not to forget, Feynman always said he had an IQ of 127, and physicists with IQs well over 160 still worship him. He had very special abilities, and it is hard to think his IQ was really 127. Yep, it's just a rough measure of intelligence.
I could say I think appraisers should have such and such skills and be done with it - but given that the audience doesn't understand the skillsets, I may substitute IQ 140 - to convey, to communicate, that the number of appraisers that have such a useful skill set is very low. And given that the majority of current appraisers are well over 50, most will never be able to pick up the new skills needed anytime soon.
