WOW!!!! You still don't get it, big time!!
I am NOT discussing your obsession with the Dunlap case as my prime concern. I AM TRYING TO WORK OUT HOW WE SHOULD EVALUATE EXPLANATIONS. You are rather confused as to what is going on here: you speak demeaningly about my 'little model' (its not 'a model' but we'll let that pass). You deny it can be useful because it is like scientific method. And yet you happily use the criteria to attack the sample explanation!!! I'll assume from this that you agree that the criteria ARE adequate to evaluate explanations.
So... my explanation is that "Somewhere deep down in his brain was a circuit that could react and fire up his whole being. And nobody could find it, because the tests just weren't precise enough, detailed enough, appropriate enough".
First...is the model to be used in assessing fact or fiction?
Unless you can demonstrate that the nuero-biological community believes your thesis...then this is purely a fictional assessement.
The criteria (not model) are to be used in assessing an offered explanation. Whether the n-b community has offered this or not is immaterial. Someone has - is it a good explanation... well, lets apply the criteria to find out.
Accuracy - predicting all or most of the data to be explained and explaining away the rest - i.e. showing where there may be errors of data collection or interpretation.
Accuracy - well, it accounts for the observable fact that ZD 'woke'. That he had appeared brain dead i.e that the AAN tests were not sufficient.
It would only be accurate if your thesis is correct....what support do you have that your thesis is correct?
Without authoritative corroboration, "accuracy" is impossible to determine, therefore making this element false.
What data was explained?
What data was explained away?
Based on what is known...given the same set of data, what other outcome could be predicted or interpreted?
You misunderstand the criterion - does the explanation address all the data? Show me what data it doesn't address - it takes all the data (the description of what happened), therefore no data needs to be explained away. Base on that data another explabnation could I am sure be proposed. You just haven't, despite numerous invitations.
Consistency - that there are no contradictions within the theory or model.
Consistency - it is internally consistent, but...
Internally consistent with what?
Does the fact that someone declared brain dead using the theories and models used to determine brain death suddenly and unexpectedly awoke reveal a contradiction with the theory or model?
"Internally consistent with what?" - huh? Do you understand what "internally consistent" means?
What are you talking about? The explanation ("Somewhere deep down in his brain was a circuit that could react and fire up his whole being. And nobody could find it, because the tests just weren't precise enough, detailed enough, appropriate enough") is what is being assessed. No other 'theory or model'.
Coherence - with surrounding beliefs and theories which are not to be superseded by the new, or at least consistency with them.
Coherent - ... it does not fit with our present view (that we can currently scan the whole brain and detect potential for recovery - i.e. the theory behind the AAN procedures).
So, you say "it does not fit".....so what does that do for us?
And we CAN scan the whole brain....and do....CAT, chemically, magnetically (MRI), with radio-nucleotides, electrically, doppler, blood flow, PET, etc......"potential for recovery" can not be determined from ALL existing tests....perhaps you can tell us what other scan can be done, without invoking Star Trek or other science fiction.
Errrm, I am simply explaining that the current tests are insufficient and that a research program is needed to try to extend them. This should take on board that ZD appeared dead, therefore there is
possibly a brain condition that needs to be searched out. Alternatively the sensitivity of the tests could be improved. You appear by your comments to believe that we know absolutely everything about the brain and can unerringly check every such aspect. I know for certain this isn't the case.
Simplicity - being expressible as economically as possible, with the fewest commitments to distinct kinds of fact and process.
Simplicity - the essence of the explanation is very simple. It does not rely on many new things, since it basically says that our current tests for brain death are lacking precision and (possibly) there is a condition that we have not previously identified - a sort of "unextinguished potential" (it is a new state, so finding words for it is a bit awkward)
Again....this element of the model fails to explain anything useful....other than we do not know what we do not know.
I think it takes a very strange type of mind to think that discovering that we do not know something is valueless.
Fecundity - making new predictions and suggesting new lines of enquiry.
Fecundity - there is a very specific research goal here: improve the definitions and tests and look for some previously unknown state. IF such a state can be identified then there is a whole new area of neural potential to be investigated.
You make it sound like the entire medical community is just sitting on it's hands.....these unanswered questions are as old as the medical profession itself.
This last sentence rather contradicts your own comment above "Unless you can demonstrate that the nuero-biological community believes your thesis...then this is purely a fictional assessement". There is an internal inconsistency here.

What you think I am 'making it sound like' is your problem, not mine.
Scope - unifying a diverse range of data.
Scope - if found, the new state will enhance our understanding of PVS, coma and brain death.
What if never found?
If we can be assured that all aspects of the brain are known, and the tests can be sharpenned to be sure that we will not misdiagnose a ZD case, then it won't matter that research for an unknown brain state is fruitless. If none of these occurs, then the probelm of what happened to Zack Dunlap will remain.
And never forget that you have furnished no explanation of your own as to what occured in the Dunlap case - so you cannot appeal to any 'better' explanation.
You would not like a theists interpretation that is as plausible as anything you come up with.
I would evaluate in exactly the same way as I have evaluated my own 'explanation' above. I suspect however that you cannot give a plausible 'theists interpretation'. If you do post one, we can assess it according to the criteria I and you have just used. You seem (more or less, apart from those you don't understand) to be happy with them as a way of evaluating an explanation. That was what I was trying to achieve - a way, a mark scheme, a formal set of headings for assessing
explanations.
So... please - explain what happened to Zack Dunlap. You may even give your stood-back evaluation using the criteria - and any other you think we need.
BTW you can take your time (I'm sure you'll need it). I will be away from tomorrow evening, on a job in India (yea, its exciting!) for the next 10-15 days.
