A hypothesis that is unfalsifiable is a failure by the scientific standard.
I see no honest way to fail something that has not been tested. I do not believe this is a feature of the scientific method, but rather of the prejudice against unfalsifiable claims of those who carry out the scientific method.
Jon, I think you have the wrong idea about what the scientific concept of "falsifiability" actually means.
Do you know what "falsifiable" means for a hypothesis or even a recognized established theory?
General Relativity is falsifiable. Why?
QCD and Evolution are falsifiable. Why?
Whether it is your definition or Mod's definition, either one, "Supernatural" is not falsifiable. Why not?
In science, a hypothesis that is not falsifiable has already failed. Why?
