Parsimony can't an arbiter. It's not a person.
yea, that is what i said...but you insist that it behaves as one.

Parsimony would be more appropriately applied when trying to develop either theory not when trying to compare theories and concluding that the simpler theory must be true, simply because of "simpler". Parsimony applies to methodology not construction....that would be validation by economy not by parsimony. Your premise that "simpler" equals "more likely" is being misapplied on these circumstances.
Again, parsimony can't be an arbiter. It's not a person. And you are right, it is methodology we use to evaluate and develop a theory. In general the simpler ideas are viewed as superior. For example, I could propose that gravity is invisible elastic bands. However, the ramifications of that idea quickly becomes complicated and in the end doesn't lead to a better understanding on the phenomena. The same is true here. How do thoughts arise? Are they due to our brain or something external like a God? Since introducing the concept of a God external to our brain introduces complexity, parsimony would tend to favor the simpler idea that thoughts come entirely from our brain alone.
I believe you are still misusing the concept as illustrated by your examples.
Parsimony would be how you go about composing, developing and/or experimenting about your elastic-band theory...not how you decide which theory to use. The notion that simpler ideas are superior is unfounded by logic, reason, or real life. A complex idea is just as likely to be valid as a simpler idea even when they are about the same subject. Its not the simplicity of idea but rather it is the simplicity of method.
So, given your example - you are still "competing" which ultimately requires arbitration - because you, erroneously,
determine the validity of something solely by how simple it is to determine. In other words, your invisible elastic band theory is not validated or invalidated by parsimony - but rather they are validated by the methods you use to test that theory - and those methods are best served by parsimony.
Now, given your question about "how do thoughts arise" - first, that is not a theory but a question. So, you actually follow with 2 theories (1) Thoughts arise because of God and (2) Thoughts arise from Brain. Parsimony is not how you determine which theory is "more correct"...(basically assuming that since theory (X) is easier to investigate it must be true). Parsimony would be exclusive only to the methods you choose to test each theory - and it may very well be that one theory is "tested" to be true even though its method may be more "complicated" in comparison.
Rube Goldberg cartoons showed how fanciful and complicated tasks could be completed. So while Rube's method of "waking up" was more complicated it still achieved the same "waking up" as a simple alarm clock.
So, the theory would be "Alarms wake people up". By which case we would test that theory either with a Rube Goldeberg machine that triggers the alarm or just a simple alarm clock. Parsimony would say to use the simple alarm clock because it is tests the theory in the simplest, most economical, and most efficient manner. (see the parsimony of the alarm clock method does not invalidate the Rube method because Rube would have proved the theory as well).
