Now I understand that most of you are not Petrologists, (although of course some of you are), but do you really need to be to question the wisdom of this prediction?
....
It seems impossible to me that any reasonable person could actually believe such nonsense, so I conclude that they in fact, do not actually believe it, despite their public commentary.
A lot of joe public will not understand why this presentation is so flawed..
in fact members of the admin and government looking to the EIA/USGS for guidance will not understand it.
It has credibility because it is official and its a graph...
We do not need to understand whether the red line...
historical instrumental data is accurate or not to see the falsehood presented in this graphic.
SPELLING IT OUT
the methodology for determining the green line is portrayed as as "averaging out" the lower and higher case estimates for future discovery.
why is that unreasonable?
well it depends on the integrity of ones upper and lower case estimates.
one can move the average green line up by increasing ones estimate of the upper case, the blue line.. in other words no matter how bad the lower case yellow line looks one can create a more optimistic green line (which the USGS claim is the most likely answer) by just adding a wildly optimistic blue line.
so to do this they need someone of some "credible" character to make a wildly ridiculous estimate
QUESTION: who? the USGS theselves or is it sourced from elsewhere?
BUT WAIT there's more
if we look at the graph we will see the lower case yellow line is an extention of the
real past historical record.. in other words the range of predictions for the future are set by the blue line.. a massive deviation from the current trend and the yellow line a continuation of the current red line.
IE the worst case scenario is not one were the current trend falls off but just continues
how honest is that?
on one hand to have a fantastically optimistic higher case that deviates massively and on the other a complete non moving trend for the lower case?
note these flaws exist even if we accept the validity of the red line.. we do not need to question USGS interpretation of past discoveries to see how statistically flawed this representation is.
recap
Flaws
1. assumes "average" of lower and higher case is the most likely truth, single high estimated skews graph. One could have 10 surveys that all pointed to the lower case and just one absurd higher case study
2. incredulous high estimate can"fix" any pessimistic scenario and create a rosy future.
3. No pessimistic lower case scenario that envisages a sharper fall off in discoveries
I'm sure some one can do this better
