Hi, everybody, 

 

This is Cranky-Nick, talking.

 

This conversation is reminding me of 538's constant reiteration that they 
actually accurately predicted Hillary's election in  2016.  It's just that the 
electoral college didn't play along.  If expert X tells me that the expected 
value of variable A is K, then, when it's all over and the data are in, and A 
did not equal K, I expect that expert to admit that what he expected did not 
happen.  Only after that confession has been made, should a conversation begin 
about whether the expert’s prediction process was faulted or not.  It seems to 
me that the shaded area is part of that second conversation.  

 

But all of that is moot because I think IHME’s optimistic predictions have 
largely panned out.  New York sent ventilators of Maryland yesterday!!!!  I 
certainly would never have expected that, but I think it follows from IHME’s 
optimistic predictions.   The were right to predict “K”, and I was wrong to 
doubt them. 

 

Can I apologize for being cranky today.  I realize I am riding for a fall.  
Thompson’s First Law: He  falls hardest who falls from his highest horse.  

 

But while I am being cranky, let me make a huge confession.  I must be a 
determinist at heart because I instinctively believe that to say an event is 
random is to confess one’s ignorance, one’s laziness, or both.  >>Pause for 
moaning, eye-rolling, and temple-pressing by all quantum-enthusiasts on the 
list.<<  I am pretty sure that what I just said contradicts my Peirce-worship, 
but there it is!  So when 538 says, our model was wonderful, we just got 
unlucky, The Leetle Voice In My Head, that voice that my behaviorism denies me, 
says back, “No, Son; you just didn’t work hard enough.”

I've quote-included what I think is the most important part of Dave's rant 
below your comment on consolidation of local outlets by right-leaning 
organizations. Dave's comment about "hard data" showing the model 
*extrapolations* being 20-50% higher than the numbers shown in local media.

 

To my eye, this seems similar to Nick's comments about the data at the IHME's 
site < <https://covid19.healthdata.org/united-states-of-america> 
https://covid19.healthdata.org/united-states-of-america>. That *huge* shaded 
area on each of those graphs seems to be totally ignored.

 

And this inability to grok uncertainty seems similar to our inability to grok 
exponential growth. Those of us who deal with such things (statistical power vs 
significance, confidence intervals vs error, standard deviation vs coefficient 
of variation, even median vs mean -- not implying *I* do so, but some of us do) 
MUST have an intuition about such things that prevents them from ignoring the 
uncertainty bands around the center/trend.

 

I also suppose the underlying cause of such judgement problems drives climate 
deniers' conflation of meteorology with climate science (or meteorologists vs 
climate scientists).

 

My own failure to grok large-scale, systemic iteration/evolution slapped me in 
the face in the form of an assertion I once made to a biologist friend, 
something like 20 years ago(?). I see/saw the democratization of music 
production (including the emergence of things like Acid Loops or LMMS < 
<http://lmms.io/> http://lmms.io/>, 
dub/rap/glitch/noise/circuit-bending/algorithmic music, as well as the 
emergence of the celebrity-not-a-musician-at-all musician/pop-star) as a sign 
that our music landscape was diversifying. The biologist retorted something 
like "Maybe *your* friends are making their own music. But that doesn't imply 
that more people are making their own music." And, over the years since he made 
that retort, I now *see* a drastic dearth of diversity all around me (though, 
again, in *my* circles, there's an increase in diversity ... it's just swamped 
by the homogeneity surrounding it).

 

 

Had Dave (or Nick) *mentioned* that -50% was well within the cone of 
uncertainty, along with condemning *both* the over-simplifying nature of local 
and national media, his assertion of "hard data" would have been credible. Hard 
data is always accompanied by a statement of how soft/hard it actually is. A 
claim of "hard data" (or optimism) with no accompanying claim of relative 
hardness is not credible. But what can we do? It's the nature of specialization 
and social trust that expert knowledge has to be simplified in order to 
percolate out.
